Abstract: The present invention provides a resin composition for sliding member and a sliding member having excellent moldability and sliding properties that contains plant-derived polyethylene resin as a main component. In the resin composition for sliding member, as additives, petroleum-derived polyethylene resin of 0.1 to 20% by mass, modified polyolefin resin of 0.1 to 10% by mass, lubricating oil of 0.5 to 5% by mass, and plant-derived filler of 0.1 to 50% by mass are blended in addition to plant-derived polyethylene resin as a main component. A sliding member is produced by molding this resin composition for sliding member.

Abstract: A slide bearing (1) is provided with an upper case (2) attached to an upper support for attaching a strut assembly to a vehicle body, a lower case (3) which is rotatably combined with the upper case (2) and which forms an annular space (7), and an annular center plate (4) and sliding sheet (5) disposed in the annular space (7). The upper case (2) has a load-transmitting surface (27) constituting part of an upper surface of the annular space (7), the center plate (4) is provided with an annular recess (43) filled with a lubricant, and the center plate (4) has a bearing surface (41) for supporting loads exerted on the load-transmitting surface (27). The sliding sheet (5), which is disposed between the load-transmitting surface (27) and the bearing surface (41), has a sliding surface (51) that slides against the bearing surface (41). The sliding sheet (5) is formed of a thermoplastic plastic, and the center plate (4) is formed from a thermoplastic elastomer having a lower modulus of elasticity than the thermoplastic plastic.
