SLIDE MEMBER FOR SHOCK ABSORBER OF VEHICLE

摘要

According to the present invention, there is provided a slide member for a shock absorber of a vehicle including a back metal, a porous sintered metal layer containing a porous sintered metal formed on the back metal and a resin with which the porous sintered metal is impregnated and covered, and a resin slide layer formed on the porous sintered metal layer and having a smooth slide surface, and the slide member is formed in a cylindrical shape so that the resin slide layer is disposed on an inner peripheral side. The resin slide layer is composed of polytetrafluoroethylene and a plurality of granular elements dispersed in the polytetrafluoroethylene, and the granular element is composed of molybdenum disulfide and molybdenum trioxide, and/or tungsten disulfide and tungsten trioxide.
