ABSTRACT OF THE DISCLOSURE This invention discloses a preventing mechanism for preventing the axial movement of a drive shaft in a hermetically sealed scroll type compressor so as to protect the members disposed therein from abrasion and breakage by vibration. The compressor includes a drive mechanism operatively connected to an orbiting scroll which orbits within a fixed scroll. The drive mechanism includes a drive shaft which penetrates the center of a pair of inner blocks and whose two ends are each rotatably supported by a bearing. The bearing is fixedly supported by the inner block. Each of the bearings includes an inner race, an outer race and a plurality of rolling elements disposed between the inner and outer races. The drive shaft engages with the inner race of the bearings so as to prevent the axial movement thereof. Accordingly, collision between the drive shaft and the internal component parts of the compressor is effectively prevented so that the internal component parts of the compressor are protected from abrasion or breakage due to vibration.
