Summary:To provide a scroll compressor which can prevent the abnormal wear and seizure of a slide part at the inside of a boss by stably supplying a lubricant into the boss of a scroll while suppressing a manufacturing cost.SOLUTION: A scroll compressor 10 comprises two scrolls 12, 13 for forming a compression chamber 101 in which fluid is compressed, and a rotating shaft 11 connected to the turning scroll 12. The rotating shaft 11 includes decentered parts (bush 21 and eccentric pin 11C) decentered to an axial core X. The turning scroll 12 includes a boss 23 into which the decentered part is inserted, and rotatably supported by a drive bearing 24 which is interposed between the boss 23 and the decentered part. An oil pocket 31 communicating with the inside of the boss 23, recessed in an axial cross direction D2, and capable of holding a lubricant is formed at the turning scroll 12.SELECTED DRAWING: Figure 2 【課題】製造コストを抑えつつ、スクロールのボスの内側に潤滑油を安定して供給することで、ボスの内側の摺動部の異常摩耗や焼付き等を防止できるスクロール圧縮機を提供すること。【解決手段】スクロール圧縮機10は、流体が圧縮される圧縮室101を形成する2つのスクロール12,13と、旋回スクロール12に連結される回転軸11とを備える。回転軸11は、軸心Xに対して偏心した偏心部(ブッシュ21および偏心ピン11C)を含む。旋回スクロール12は、偏心部が挿入されるボス23を含み、ボス23と偏心部との間に介在する駆動軸受24により回転自在に支持される。旋回スクロール12には、ボス23の内側に連通し、軸交差方向D2に窪んで潤滑油を保持可能な油ポケット31が形成されている。【選択図】図2
