Abstract
A sliding device 1 is constituted of a swash plate 3 including a first sliding surface 3A and a semispherical shoe 4 sliding with the swash plate 3. The swash plate 3 is constituted of a base material 3B of high strength brass containing Mn and Si, and very small granular Mn—Si compounds 6 are exposed on an inside of the base material 3B and on the first sliding surface 3A (surface of the base material 3B). The above described swash plate 3 increases in exposure amount of the Mn—Si compounds 6 exposed on the first sliding surface 3A by applying etching to the base material 3B after cutting the base material 3B. The sliding device 1 is favorable in seizure resistance and has a low manufacturing cost as compared with conventional sliding devices.
