    摘要： The disclosure relates to a sliding member. This sliding member includes a base material, and an amorphous hard carbon film formed on a surface of the base material, in which a sp 2 ratio of the amorphous hard carbon film increases from an inner surface side corresponding to the base material side toward an outer surface side thereof to become a maximum value and further decreases toward the outer surface side.

    摘要： A piston ring (1) which is resinous includes an annular main body portion (2) having an inner peripheral surface (2c) and an outer peripheral surface (2d) facing each other and a pair of side surfaces (2a, 2b) interconnecting the inner peripheral surface (2c) and the outer peripheral surface (2d) and a joint portion 3 formed in the main body portion (2). The joint portion (3) has a step shape when viewed from at least one of the pair of side surfaces (2a, 2b) and the outer peripheral surface (2d). The outer peripheral surface (2d) has a tapered surface having an outer diameter increasing from a side of one side surface (2a) of the pair of side surfaces of the main body portion (2) toward a side of the other side surface (2b).

    摘要： [Object] To provide a seal ring such that an oil leak can be inhibited while a friction loss is decreased. [Solving Means] A seal ring according to a first aspect of the present invention includes a center axis, an outer peripheral surface, an inner peripheral surface, a side surface, and a groove. The center axis is a rotation center. The outer peripheral surface is an outward cylindrical surface whose center is positioned at the central axis. The inner peripheral surface is an inward cylindrical surface disposed between the center axis and the outer peripheral surface whose center is positioned at the central axis. The side surface connects the outer peripheral surface and the inner peripheral surface. The groove is formed in a dented groove from the side surface, extends along a radial direction spaced from the outer peripheral surface, has a first end connected to the inner peripheral surface and a second end at an opposite side of the first end, and returns oil entered from the first end to an inner peripheral surface side via the second end.
