PURPOSE:To sufficiently maintain the height of an oil level even in case of the oil level of an oil basin chamber being inclined and to surely feed an oil always by arranging the volume body having the specified volume at the space of the oil basin chamber fitted to the lower end part of a cylinder block. CONSTITUTION:An oil basin chamber 2 is faxtened by a bolt 3 at the lower end part of a cylinder block 1. An oil strainer 17 is then arranged at the inner part of the oil basin chamber 2. In this case, the volume body 19 having the specified volume is arranged between the oil level 18a of an oil 18 inside the oil basin chamber 2 and a crankshaft 6 and fastened by a bolt 20 to the lower end of a skirt part 1b. At the time when the oil level 18a is inclined 18a'' at the revolving and speed adjusting times of a vehicle one part of the volume body 19 is set under the oil level to ascend 18a' the oil level by the volume part thereof. The oil level at the inlet port part 17a of the oil strainer 17 is ascended and the suction prevention of an air and the suction security of an oil are achieved. |
