<p>A scroll type compressor which prevents occurrence of abnormally high pressures due to liquid compression at the time of startup so as to lighten the engine load by providing a projection (100a) on the end face of the shaft (100) and a groove (101a) in which the projection fits in the end face of the bush (101) supporting a movable scroll member (200), the projection and groove being arranged so that their abutting faces (100d,101d) are inclined a predetermined angle ( THETA ) with respect to a line connecting the center (100b) of the shaft and the center (101b) of the bush in the direction opposite to the rotational direction of the shaft and being positioned relative to each other so that the extension line of the abutting faces passes through the side opposite to the side where the center of the bush is positioned seen from the center of the shaft. <IMAGE> <IMAGE></p>
