PROBLEM TO BE SOLVED: To solve the following problem: since oil is supplied to a slide part by using only centrifugal force caused by rotational movement, there is a possibility that oil runs out in the slide part after restarting a refrigerant compressor. SOLUTION: This refrigerant compressor is equipped with a connecting rod 122 for forming a slit groove 124 one end of which is in communication with the slide surface of a small end hole 19 and the other end of which is in communication with the top face of an arm part 121. Since oil 102 is retained in the slit groove 124 when the compressor is stopped, by forming the slit groove 124, oil is surely supplied to the slide surface of the small end hole 119 even immediately after restarting it. Thereby, oil between the slide surface of the small end hole 119 and a piston 112 does hardly run out, and the highly reliable refrigerant compressor can be provided. COPYRIGHT: (C)2006,JPO&NCIPI
