Bearing 10 includes: a half bearing member having an inner circumferential face that slides against an associated shaft, and a plurality of recesses provided in a first end face in an axial direction of the associated shaft; a first flange member having a plurality of projections provided at positions corresponding to the plurality of recesses provided in the first end face; and a plurality of staking marks formed in a periphery of each recess when each recess is staked in a state where each of the plurality of projections is fitted to a corresponding one of the plurality of recesses in the first end face to fix the first flange member to the half bearing member. When staking marks formed on both sides of at least one of the plurality of recesses are viewed in a radial direction of the associated shaft, a volume of a deformed portion near a staking mark located outside in a circumferential direction is smaller than a volume of a deformed portion close to a staking mark located inside.

Provided are an oil feed member that makes it possible to ensure a wide distance between oil passages and to achieve space saving in the oil passages and a lubricant feed mechanism of an engine provided with the oil feed member. An oil feed member includes a lubricant passage and a plurality of discharge ports that are formed on the downstream end of the lubricant passage and discharge lubricant flowing through the lubricant passage to a lubrication portion. The lubricant passage includes a basis oil passage, a first upstream branch oil passage that branches off from the basis oil passage and allows lubricant guided to the discharge ports to flow therethrough, and a second upstream branch oil passage that branches off from the basis oil passage and allows lubricant guided to the discharge ports to flow therethrough.


In a method, in which a plain bearing alloy layer is bonded to a surface of a backing steel sheet, and, a Bi-based overlay layer is then deposited on the plain bearing alloy layer by electroplating, replacement of Bi with the backing steel sheet and deposition of Bi on the backing steel sheet are prevented. Prior to the step of electroplating of the Bi-based overlay layer, the following metals and the like are formed on at least the back surface of the backing steel sheet. An electrochemically more noble metal than Bi, an electrochemically more base metal than Bi and capable of forming a passivation state, or resin.

The rotation of a bearing is suppressed without the need for a projecting portion on an outer circumferential surface of an arc portion in the bearing. Bearing 10 includes arc portion 11 in which a cross section orthogonal to an axial direction has an arc shape, and rotation suppressing portion 12 and rotation suppressing portion 13 that extend respectively from a first end and a second end of an arc in arc portion 11 and include a portion projecting outward from a circumcircle of arc portion 11 in the cross section orthogonal to the axial direction.


Provided are an oil feed member that makes it possible to ensure a wide distance between oil passages and to achieve space saving in the oil passages and a lubricant feed mechanism of an engine provided with the oil feed member. An oil feed member 100 includes a lubricant passage and a plurality of discharge ports 134 (134a to 134d) that are formed on the downstream end of the lubricant passage and discharge lubricant flowing through the lubricant passage to a lubrication portion. The lubricant passage includes a basis oil passage 150, a first upstream branch oil passage 125 that branches off from the basis oil passage 150 and allows lubricant guided to the discharge ports 134a and 134b to flow therethrough, and a second upstream branch oil passage 126 that branches off from the basis oil passage 150 and allows lubricant guided to the discharge ports 134c and 134d to flow therethrough.

First closing member 2 and second closing member 3 close opening portions at both ends of cylindrical member 1 in an axial direction. Base 411 is housed in a space formed by cylindrical member 1, first closing member 2, and second closing member 3, and rotates around an axis in the same direction as the axial direction of cylindrical member 1. Resin layers 410 are formed on thrust surfaces of base 411. Groove C is a plurality of concentric circular grooves or a spiral groove formed on each resin layer 410, and the center of circles of the circular grooves or the center of a spiral of the spiral groove is different from the rotation center of base 411.

There is provided a slide bearing capable of preventing or reducing the likelihood of the occurrence of galling while being provided with an oil groove in its inner periphery. A cylindrical main bearing 2 is formed by combining an upper bearing 10 disposed on an upper side and a lower bearing 20 disposed on a lower side and rotatably supports a crank journal 1 a through an oil film between the cylindrical main bearing 2 and the crank journal 1 a. The lower bearing 20 includes an oil groove 23 formed in a low-load region L set in a range in which a pressure from the oil film is low on the inner periphery of the lower bearing 20.

Provided is a slide bearing 1 with which friction can be reduced and the total amount of effluent oil can be reduced. In the slide bearing (1) in which the halved members (2), (2) made by dividing the cylinder in two in the direction parallel to the axial direction are disposed vertically, the narrow grooves (33) are provided at an end of the lower halved member (2) in the circumferential direction from a mating surface on a downstream side of a rotation direction to a predetermined bearing angle (1) and peripheral edge parts (32a) are provided outside the narrow grooves (33) in an axial direction.
