The purpose of the present invention is to enable stable motion, remote control, etc. by configuring a nut, which engages with the rod of a clearance piston through screw threads, in such a manner that the nut is composed of two bodies engaged with each other through a spring member and that the nut is engaged with the rod without play. This clearance pocket for a reciprocating compressor has: a rod (59) which is provided to a clearance piston (58), has a male thread (59a), and is held by a rotation restriction element (84) so as not to be rotate; a nut (74) engaging with the male thread (59a); and first and second nut sections (75, 76) which form the nut (74) and are engaged with each other by being pressed in the opposite directions by the spring member (77). There is no play in the engagement between the threads, and stable motion can be obtained even if a varying load is applied to the rod (59). |
