Abstract
A sliding member includes: a lining layer formed from an alloy having a predetermined shape; and an overlay layer formed on an inner circumferential surface of the lining layer, the overlay layer being formed of a resin, the overlay layer sliding with a shaft, the overlay layer including a raised portion a height of which in a predetermined area including each of an edge in an axial direction of the shaft is greater than a height of another area of the overlay layer.

A sliding member comprising:
- a lining layer formed from an alloy having a predetermined shape;
- and
- an overlay layer formed on an inner circumferential surface of the lining layer, the overlay layer being formed of resin, the overlay layer being configured to slide along a shaft, the overlay layer including a raised portion in a predetermined area at each axial edge of the overlay layer, a height of the raised portion being greater than a height of an entire remainder of the overlay layer,
- in a cross section parallel to an axial direction, the height of the overlay layer gradually decreases from a top of the raised portion to the axial edge.

A sliding member comprising:
- a lining layer formed from an alloy having a predetermined shape;
- and
- an overlay layer formed on an inner circumferential surface of the lining layer, the overlay layer being formed of resin, the overlay layer being configured to slide along a shaft,
- the overlay layer including:
- a first radially projecting rib extending in a circumferential direction along a first axial edge of the overlay layer,
- a second radially projecting rib extending in the circumferential direction along a second axial edge of the overlay layer, and
- an uninterrupted surface occupying an entire area between a base of the first rib and a base of the second rib,
- the uninterrupted surface being:
- recessed relative to the first and second ribs, and
- substantially planar in cross section,
- in a cross section parallel to an axial direction, the height of the overlay layer gradually decreases from a top of the first and second radially projecting ribs to the first and second axial edges, respectively.
