Abstract
A method of manufacturing a shoe including cutting a columnar raw material to a given length to provide a disc-shaped raw material, forming on one end face of the disc-shaped raw material a spherical sliding surface which is to be disposed in sliding contact with a spherical surface on a piston, and forming a thermal sprayed layer on the other end face of the disc-shaped raw material. The thermal sprayed layer serves as a flat plate-shaped sliding surface which is to be disposed in sliding contact with a swash plate. A shoe which is provided with the thermal sprayed layer exhibits an increased seizure resistance in comparison to a conventional shoe which is formed with a sintered layer, and can be manufactured inexpensively.
