1. A compressor, comprising:
a cylinder having a compression chamber and a blade housing in communication with the compression chamber; a first end plate member and a second end plate member disposed on axial ends of the cylinder; and a piston disposed in the compression chamber and inside the blade housing, the piston including an annular roller disposed in the compression chamber and a blade extending from an outer circumference surface of the roller and disposed in the blade housing so as to be movable forward and backward; a resin layer including a stack of three or more layers being formed on at least a portion of at least one of
an axial direction end surface of the piston,a surface of the first end plate member opposed to the axial direction end surface of the piston,a surface of the second end plate member opposed to the axial direction end surface of the piston,the outer circumference surface of the roller, andan inner circumference surface of the compression chamber, a hardness of a layer most distant from a base in the resin layer being smaller than a hardness of a layer closest to the base in the resin layer, and a difference in hardness between two adjacent layers in the resin layer being smaller than a difference in hardness between the layer most distant from the base and the layer closest to the base. |
