ABSTRACT:
A front housing (20) has a shaft hole (210) and an oil path (20a) communicating with a crank chamber (15) and the shaft hole to lubricate a bearing supporting a drive shaft (3) and and a shaft seal contained in the shaft hole. A lubricating oil in the crank chamber (15) is scraped by the rotation of the drive shaft (3). An oil trap (19) is formed at one end of the oil path (20a) to effectively collect the lubricating oil which is supplied through the oil path (20a) to the shaft hole (210). The oil trap (19) is formed by a part of a first thrust race (201b) and an oil receiving groove (20g). The first thrust race (201b) has a plurality of finger portions (201d) bent towards a bottom surface of an annular groove (204) formed in an internal wall surface of the front housing (20). The annular groove (204) has a plurality of fitting holes (20h) for receiving the finger portions (201d) therein in one-to-one correspondence. The finger portions (201d) are fitted into the fitting holes (20h) to thereby inhibit the rotation of the first thrust race (201b).
