PROBLEM TO BE SOLVED: To prevent grease loss, noise, discoloration, and abrasion, by forming at least one linear grease groove on the surface of a liner plate which contacts with a rolling bearing in almost parallel with the longitudinal direction of the rolling bearing. SOLUTION: In the center part of the surface of a liner plate 6 which contacts with a rolling bearing 5, and in the center part of the surface of a cross-slider 2, linear grease grooves 20, 21 which accumulate grease and supply it between the both parts are formed in almost parallel with the longitudinal direction of the rolling bearing 5. Thus, by forming grease grooves 20, 21 on the surfaces of the liner plate 6 and the cross-slider 2 which slide and become hot, grease is satisfactorily accumulated in both of the grease grooves 20, 21, and the grease is supplied to the sliding surfaces. Therefore, even when a multistage compressor is driven continuously, grease loss, noise, discoloration, and abrasion can be prevented on the sliding surfaces of the rolling bearing 5, the liner plate 6, and the cross-slider 2. |
