As described above, by opening the lower end surface of the skirt (77) close to the bottom surface of the oil sump (1a),
The lower end of the skirt (77) becomes the suction opening of the pump (7), and the effective oil amount in the oil reservoir (Ia) can be taken up to the lower end of the skirt (77). As a result, the amount of effective oil can be increased and the amount of wasted oil can be reduced. Further, when the lubricating oil in the oil sump (1a) is sucked into the suction port (73) through the inside of the skirt (77), the area of the suction opening formed from the lower end of the skirt (77) is Since it can be made larger than the suction port (73), the suction flow rate of the lubricating oil passing through the gap between the lower end and the oil m (L a, ) is reduced, which reduces the suction of dirt into the suction port (73). is effectively prevented, and a strainer is not particularly required. Therefore, with a simple configuration and low cost, it is possible to increase the amount of effective oil in the oil reservoir (1a) and prevent dust from being sucked in.
