PURPOSE:To adequately supply the lubrication oil to the bearing by extending a packing interposed between the mating surfaces of dividable cases into the upper part of an oil well to form a partition dividing the case into the left and right hand sides. CONSTITUTION:A packing 12 interposed between the mating surfaces of dividable cases 1, 2 is extended to the mating surfaces of extensions 16a, 16b, and a partition 18 large enough to divide an oil well 9 into the left and right hand parts is formed integrally with the packing 12. In this manner, even when there is a step in the mating area of the cases 1, 2 forming the oil well 9 due to the manufacturing tolerance, the lubrication oil can be supplied to bearings 4 on both sides almost evenly. Therefore, a seizure of the bearings 4 can be positively prevented.
