PURPOSE:To obtain a simple structure and improve fabrication performance by forming, on an oil pipe, a branched part which crosses at right angles with a case divided surface and inserting said pipe into one case and assembling the other case so that the divided surface is fitted. CONSTITUTION:An oil pump 25, the main pipe 38a of a T-shaped pipe 38 and the left side 38b of a branched-pipe part are fabricated beforehand onto a left- half body 21. A rib 38e is installed upstream on the top edge part 38f of a right branched-pipe part 38c, and a seal ring 39 is fitted beforehand onto the periphery of said top edge part 38f, and said top edge part 38f is inserted into a small diameter part 43c from the stepped part 43b of the opening part 43a of a transverse passage 43 when a right-half body 22 is joined, and the seal ring 39 is attached under pressure by the rib 38e and the shoulder part of the stepped part 43b, and thus seal is performed. Since a feeding passage leading from the oil pump 25 is formed through mutual joint of the half bodies, the accuracy and the fabrication performance can be improved with a simple construction. |
