A tolerance ring for a torque transmission device is arranged in an annular space between an inner shaft member and an outer shaft member. The tolerance ring has a ring-shaped portion and a plurality of protrusions. The ring-shaped portion has a cylindrical shape and is brought into contact with one of the shaft members. The plurality of protrusions undergo elastic deformation and are arranged in a peripheral direction. The ring-shaped portion has seat portions formed between the protrusions that are adjacent to each other in the peripheral direction. The plurality of protrusions include selected protrusions that have the same shape and that are situated at the same axial position and unselected protrusions other than the selected protrusions. The selected protrusions and the unselected protrusions differ from each other in axial position of center point in a length direction.

A purpose is to render a gripping operation of grip tabs more stable. A hose clamp (1) includes a clamp body (3) formed by bending a plate spring into an annular shape while two ends of the plate spring are caused to cross each other on a circumferential plane and grip tabs (51, 52) formed to be raised radially outward from both ends of the clamp body (3), respectively. An expanded-diameter state of the clamp body (3) is retained when a locking claw (34) is locked by a catch (35). The clamp body (3) is released from the expanded-diameter state when a gripping operation is further carried out in this state. The second grip tab (52) has a distal end formed to be wider than a distal end of the first grip tab (51). The distal ends of the grip tabs (51, 52) are bent in respective directions in which the distal ends depart from each other with respect to a thicknesswise direction, thereby serving as bent portions (61, 62) for the gripping operation, respectively.

Embodiments of the present invention may include a connector cover covers a connector body having a pipe connection portion to which a pipe is connected and a tube connection portion to which a tube is connected. The connector cover has two divisional bodies formed through division in a radial direction of the connector body and configured to be capable of being engaged with each other. At least one of the divisional bodies has a large-diameter fit-engagement portion fit-engaged with a divergent portion of the tube connected to the tube connection portion, and a small-diameter fit-engagement portion which is of a smaller opening diameter than that of the large-diameter fit-engagement portion and which is fit-engaged with a non-divergent portion of the tube adjacent to the large-diameter fit-engagement portion.

Preventing a checker from becoming waste even after fulfillment of a detecting function and stably maintaining a retainer in a locking state. A pipe connector includes a connector body (1), a retainer (2) preventing a pipe from pulled from the connector body (1) and a checker (3) detecting normal insertion of the pipe. The checker (3) is formed with front legs (37). When the pipe (P) has been inserted into a normal position, the front legs (37) are spread by a flange (10) of the pipe (P) with the result that the checker (3) is released from the lock to the connector body (1). Consequently, the checker (3) is movable from a preliminary holding position to a detection position by pressing a cover (34). Locking legs (26) are spread when a release operation portion (28) of the retainer (2) has been pressed, so that the pipe (P) is allowed to be pulled from the connector (1). However, when the checker (3) assumes the detection position, the release operation portion (28) of the retainer (2) is covered with the cover (34) with the result that the retainer (2) is prevented from inadvertent unlocking.

A purpose is to increase a clamping force without increase in a plate thickness. A wide region (X1) is formed at one of lengthwise sides to be relatively wider and has portions bifurcated by an opening (2). A narrow region (X2) is formed at the other lengthwise side to be relatively narrower and has a portion passed between the bifurcated portions. Both widthwise side edges of the wide region (X1) are formed with respective flanges (6) by bending and a bead (7) is formed on a widthwise middle of the narrow region (X2). The flanges (6) and the bead (7) are set so that a change in a section modulus is substantially symmetric about a Y axis that is a lengthwise central axis of the hose clamp.

An inlet hole capable of inserting a pipe thereinto is formed in a pipe joint body along an axis. Retainer attaching holes for attaching with a retainer that prevents detachment of the pipe are formed in a side surface of the pipe joint body to extend therethrough. These retainer attaching holes are configured symmetrically with respect to an X axis passing through a center of the inlet hole as a symmetrical axis. Thus, a circumference of the inlet hole opens symmetrically, so that the heat shrinkage condition after molding is equalized in the circumferential direction. Accordingly, it is not necessary to process a molding pin for the inlet hole with imbalance of heat shrinkage amount in mind, so that the molding pin becomes easy to process. In addition, the retainer can selectively utilize the retainer attaching holes at two positions, so that selective use depending on installation environment can be achieved.

The pinching operation is facilitated. A hose clamp (H1) is formed by bending a strip-like plate material (1) into a ring-like configuration, and includes a first end portion (5) having a first pinching operation surface (9), and a second end portion (6) having a second pinching operation surface (15). A through-hole (7) is open near the center in the longitudinal direction of the first pinching operation surf ace (9). At the time of bending into ring-like configuration, expansion regions (19) arranged at both side portions in the width direction of the second pinching operation surface (15) are folded at folding edges (20) with respect to a proximal region (18), whereby the second pinching operation surface (15) is narrowed in the width direction and can enter the through-hole (7). After bending into ring-like configuration, the expansion regions (19) are unfolded at the folding edges (20) and regain a widened state.

This torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body comprises a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.
