PURPOSE:To simplify fitting of a transmission gear by providing, in the engaging part of a transmission body, a locking projection to be engaged in a locking groove on the clutch outer periphery, providing a guide projection on the reservoir side. CONSTITUTION:A transmission body 5 is provided with an engaging part 3 for engaging an one-way clutch 2 placed on a reciprocal rotary axis 1 with the inner periphery, and the provided with a reservoir 4 for lubricating oil adjoining to said engaging part 3. And, the engaging part 3 is provided with a locking projection 7 for engaging guiding a locking groove 6 formed in the axial direction onto the outer periphery of the one-way clutch 2, and a guide projection 8 is provided on the reservoir 4 side for guiding the locking groove 6 to the position of the locking projection 7 by engaging with the locking groove 6. Now, when the one-way clutch 2 is fitted into the engaging part 3 from the reservoir 4 side while adapting the guide projection 8 to the locking groove 6 during an assembly process the locking groove 6, 5 is guided by the guide projection 8 in order to be further guidedly engaged with the locking projection 7 for locking the rotation in the axial direction of the transmission body 5. Consequently, assembly process of a transmission gear can be easily carried out.
