PURPOSE:To make yet highly speedier operation performable, by forming a part of the sliding part of a compressor with the plastic material made up of compounding a reinforcer such as a carbon fiber, a glass fiber or the like and an abrasion resisting modifier with crystalline ternary system aromatic polyester. CONSTITUTION:A compressive mechanism part being driven by a motor part 1 to be housed in a hermetically sealed vessel of a rotary compressor for dichlorodifluoromethane compression has a roller 8 and a vane 9 or the like as its sliding parts. And, these sliding parts are molded with the plastic material made up of polymerizing a reinforcer and an abrasion resisting modifier with crystalline ternary aromatic polyester to be obtained by making a monomer or a polymer of hydroxycarboxylic acid, aromatic diol and aromatic dicarboxylic acid react into condensation polymerization, so as to cause the total of the reinforcer and the heat resisting modifier to become less than 40% of total. The reinforcer uses a carbon fiber, a glass fiber, a ceramic fiber or the like, while the abrasive resisting modifier uses ethylene tetrafluorise resin, black smoke power or the like.
