Description of the Related Art As illustrated in FIG. 7, a gear 1 and a gear 2 in a vehicular transmission are engaged with each other by a spline portion 3, and the gear 2 is formed by bearings 4 and 4 of a transmission (not shown). In the case where the gear 2 is rotatably supported by the casing, the gear 2 conventionally has a shaft hole 5 and an oil hole 6 extending in the radial direction of the shaft hole 5 and communicating the spline portion 3 and the shaft hole 5. As a result, the lubricating oil in the transmission case hits the baffle plate 7 fixed in the transmission casing, and the lubricating oil is fed into the shaft hole 5 by being appropriately bounced off by the baffle plate 7, and the lubricating oil is sent into the shaft hole 5. The internal lubricating oil is configured to receive centrifugal force due to the rotation of the gear 2 and to be guided from the oil hole 6 to the spline portion 3 to prevent wear of the spline portion 3. Must be provided separately , The number of parts is increased, to join their assembly steps, there is a problem that much cost is increased.

The stored lubricating oil flows into the shaft hole from the other end of the lubricating oil guide that is close to the opening of the shaft hole or that extends into the opening, and is rotated from the shaft hole through an appropriate oil hole. Guided to the outer peripheral surface of the shaft, the outer peripheral surface can be lubricated appropriately, but since the lubricating oil guide is formed integrally with the casing or the retainer of the bearing, lubricating oil is supplied into the shaft hole of the rotating shaft. Therefore, the number of components required for performing such operations does not increase, and the man-hour for assembling those additional components is not required at all. Moreover, the lubricating oil guide is disposed on an extension of the shaft hole in the rotary shaft, and the stored lubricating oil in the shelf formed at one end of the lubricating oil guide flows into the shaft hole from the other end of the lubricating oil guide. In addition, the structure of the lubricating oil supply path to the shaft hole can be greatly simplified.
