摘要

A sliding end part (18) of a shoe (7) has an annular seal part (60) located to surround one opening of a lubricant supply hole (52) and sliding on a slide-receiving surface. The sliding end part (18) has a first pad part (61) that has a height from a reference surface (65) lower than the seal part (60), that is located on the same circumference to partially surround the opening, and that faces the seal part (60) in a radial direction via an annular groove present on an inner side in the radial direction of the seal part (60). The sliding end part (18) has a second pad part (62) that has a height from the reference surface (65) lower than the seal part (60), that is located on the same circumference to partially surround the opening, and that faces the seal part (60) in the radial direction via an annular groove present on an outer side in the radial direction of the seal part (60).
