In the case 10, a flow pipe 11 is formed. The oil pipe 11 of the case 10 is connected to a radiator (not shown) for cooling the oil, and the oil flowing along the oil pipe 11 is cooled by air cooling or water cooling while passing through the radiator. The radiator extends outward and is connected to the transmission of the vehicle.

The oil supply pipe 20 communicates with the flow pipe 11 and supplies oil to the flow pipe 11. The oil supplied to the oil supply pipe 20 is cooled by heat exchange in an air-cooled or water-cooled manner in a radiator provided in the vehicle transmission. The oil supply pipe (20) is provided with a through hole (21) communicating with the flow pipe (11). The fastening member 30 penetrates through the through hole 21 and the oil supply pipe 20 and the case 10 are fastened and fixed to each other.

The fastening member 30 passes through the through hole 21 of the oil supply pipe 20 and fastens the oil supply pipe 20 to the case 10. The fastening member 30 is tightened by the rotation and presses the oil supply pipe 20. The fastening member 30 includes a body portion 31 and a head portion 33.

The body 31 is hollow and has a thread formed on its outer circumferential surface. The body 31 is inserted into the case 10 through the oil supply pipe 20 and is screwed. A thread corresponding to a thread formed on the outer peripheral surface of the body 31 is formed in the case 10 into which the body 31 is inserted.

An oil inflow hole (35) is formed through the side surface of the body portion (31). The oil inflow hole 35 communicates with the flow pipe 11 to transfer the oil flowing from the oil supply pipe 20 to the flow pipe 11. That is, the oil flows through the oil supply pipe 20 to the flow pipe 11 through the oil inflow hole 35, and is transferred to the radiator connected to the case 10. The oil transferred to the radiator is cooled in a radiator in an air-cooled or water-cooled manner.
