Abstract
A sliding device 1 includes a swash plate 3 rotated in association with a rotating shaft 2 and semispherical shoes 4 sliding on the swash plate 3. The semispherical shoes 4 are formed of a ferrous material and the swash plate 3 is manufactured using high-strength brass as a material.On a sliding surface 4A of the shoe 4, a large number of minute annular expandingly projecting parts 7′ are formed by laser hardening and a lubricating oil passage 10′ consisting of a reticular concave part is also formed.Thereby, a sliding device 1 having excellent seizure resistance as compared with conventional sliding devices can be provided.
