A rear imaging device is provided. The rear imaging device is attached to a mobile object such as a vehicle, and is provided with an imaging device for imaging an area rearward of the mobile object, and a housing for housing the imaging device. At a rear end portion of the housing, drainer pieces are formed extending rearward. A plurality of the drainer pieces are formed in a circumferential direction of the housing. Tip end portions of the drainer pieces are formed narrower toward tip points thereof, with base portions of the adjacent drainer pieces being adjacent to each other.

This invention enables obtainment of a reflectance variable element having a high cold tolerance. Two transparent substrates are disposed so as to face each other across a gap. On respective surfaces of the transparent substrates, the surfaces facing each other, respective transparent conductive films are formed. An electrolytic solution is charged in the gap. The electrolytic solution has a composition in which at least silver ions and copper ions, a content by weight of the copper ions being smaller than that of the silver ions, are contained in a non-aqueous solvent containing a non-aqueous solvent having a boiling point that is higher than that of methanol and methanol, a content by weight of the methanol being smaller than that of the non-aqueous solvent.


A casing of a turn signal lamp assembly includes a lamp housing and an outer lens, each of which includes a transparent member, being overlaid on each other and joined to each other at peripheral edges. The lamp housing includes a light entrance portion that receives incident light emitted from a light source, a light-guiding lens portion that guides the incident light, and a light exit portion that outputs the guided light.


The present invention is intended to, when rotation of a mirror rotation unit in a power-folding mirror is mechanically locked and its drive motor is thereby locked, make it possible to correctly detect this locked state. A motor 10 for a power-folding mirror is reversibly driven by an H-bridge drive circuit 12 formed of FETs 1 to 4. When the motor 10 is driven in normal rotation by turning the FETs 1 and 4 on and turning the FETs 2 and 3 off, the FET 1 is periodically turned off to detect a voltage of a terminal 10a of the motor 10 by means of a voltage detection circuit 14. When the FET 1 is turned off and the motor 10 is not locked, the motor 10 generates power by means of its inertial rotation, and when locked, the motor 10 generates no power, so the voltage detected by the voltage detection circuit 14 changes according to whether or not the motor 10 is locked. A CPU 20 determines whether or not the motor 10 is locked according to the voltage detected by the voltage detection circuit 14.

In a hydrophilic member including a structure in which a photocatalytic TiO_(2 )layer and a porous SiO_(2 )layer are stacked on a surface of a base material, easy forming of the porous SiO_(2 )layer so as to be thin and have a uniform film thickness distribution that enables the porous SiO_(2 )layer to cover an entire surface of the photocatalytic TiO_(2 )layer, and enhancement in durability of the porous SiO_(2 )layer are enabled. A photocatalytic TiO_(2 )layer is formed so as to have a density of 3.33 to 3.75 g/cm^(3 )(preferably 3.47 to 3.72 g/cm^(3), more preferably 3.54 to 3.68 g/cm^(3)) on a surface of a base material. As an outermost surface layer, a porous SiO_(2 )layer is formed on the photocatalytic TiO_(2 )layer in such a manner that the porous SiO_(2 )layer has a film thickness of no less than 10 nm and no more than 50 nm.

While a light source is arranged on the back side of a light guide lens, light beams can be emitted from the light source with respective optical axes directed in one direction and be guided toward opposite ends of the light guide lens. A light source and a reflective surface are arranged on the back side of a light guide lens. The light source emits light beams with respective optical axes directed in one direction. One of the light beams obliquely enters the light guide lens toward one end in a long direction of the light guide lens without being reflected by the reflective surface. Another one of the light beams is reflected by the reflective surface and obliquely enters the light guide lens toward another end in the long direction of the light guide lens.

The need for an O ring cover is eliminated when a gap between a shaft portion of a mover for mirror surface angle detection and a hole in a sensor case is sealed using an O ring. An O ring that allows a shaft portion of a slide block to be inserted therethrough is interposed between a sensor case and an actuator housing. The sensor case and the actuator housing are interconnected by means of screw-fastening via screws, and the O ring is brought into pressure contact with and held between the sensor case and the actuator housing by means of the screw fastening forces.

Moving a mover for mirror surface angle detection following a nut member along a male thread member in such a manner that the mover is rotatable relative to the nut member and is non-rotatable relative to the male thread member, without biasing the mover by means of a spring. A communication hole is provided in a male thread member along a shaft axis of the male thread member. A mover is inserted through the communication hole so as to be movable in an axial direction. A front end of the mover is connected to a position in a back of a front end of a nut member so as to be rotatable relative to the nut member around the axis of the nut member. A position detection device detects a position of the mover relative to a base member in a direction along the male thread member.
