Swash plate

Abstract

A swash plate has a base material having an annular shape including a surface facing a mating member, a plurality of grooves extending in a direction intersecting with a sliding direction of the mating member on the entire circumference of the annular shape on the surface, and a resin coating layer formed on the surface and forming a sliding surface with the mating member.

1 . A swash plate comprising:
 a substrate having an annular shape including a surface facing a mating member;   a plurality of grooves extending towards a direction intersecting the sliding direction of the mating member on the entire circumference of the annular shape on the surface; and   a resin coating layer formed on the surface and forming a sliding surface with the mating material.   
     
     
         2 . The swash plate according to  claim 1 , wherein
 the plurality of grooves extend radially from a center of the annular shape.   
     
     
         3 . The swash plate according to  claim 1 , wherein
 in the plurality of grooves, the distance between adjacent grooves is 20 to 240 μm.   
     
     
         4 . A swash plate according to  claim 1 , wherein
 the roughness of the surfaces is 5 to 15 μm (RzJIS).   
     
     
         5 . The swash plate according to  claim 2 , wherein
 in the plurality of grooves, the distance between adjacent grooves is 20 to 240 μm.   
     
     
         6 . A swash plate according to  claim 2 , wherein
 the roughness of the surfaces is 5 to 15 μm (RzJIS).   
     
     
         7 . A swash plate according to  claim 3 , wherein
 the roughness of the surfaces is 5 to 15 μm (RzJIS).   
     
     
         8 . A swash plate according to  claim 5 , wherein
 the roughness of the surfaces is 5 to 15 μm (RzJIS).
