Abstract
In a scroll compressor, a fixed scroll () and a movable scroll () each having a spiral body are engaged with each other, grooves () extending along the spiral shape of the spiral body are formed on the forward end surface of the spiral body of at least either one of the fixed scroll and movable scroll, and tip seals () are disposed in the grooves so as to project from the forward end surface and be slidable on the bottom plate surface of the other scroll facing the forward end surface. The tip seals have large projection parts () with a larger amount of projection from the forward end surface and small projection parts () with a smaller amount of projection from the forward end surface, and the large projection parts and small projection parts are arranged alternately in the direction along the spiral shape of the spiral body. The scroll compressor does not produce an excessive load at the end of the wall of the scroll while achieving the same sealability as in the case of conventional structures, i.e., the efficiency of the compressor can be improved.
