PURPOSE:To reduce the abrasion of a vane, vane groove of a cylinder, and the outer periphery of a roller by making a vane from sintered material and allowing the vacant holes of the sintered material to be impregnated with solid lubricant. CONSTITUTION:A vane 18 is made of a sintered material, and the vacant holes in the sintered material are impregnated with solid lubricating agent. Therefore, when a motor-driven part 9 is driven, the vane 18, vane groove 21 of a cylinder 13, and the outer peripheral surface 20 of a roller 17 move in sliding, and abrasion can be reduced markedly by the self lubricity of the vane 18. |
