A clutch sleeve 5 connects the intermediate shaft 3 and the output shaft 4 and transmits the torque of the intermediate shaft 3 to the output shaft 4. A ball bearing 6 is fitted in the front interior of the extension housing 1, and a rear bushing 7 is fitted in the rear interior. Rotatably supported. intermediate shaft 3
A lubrication passage 8 is provided through the axial center of the shaft, and a plug 9 is attached to the rear end thereof. The lubricating oil pumped through the lubricating passage 8 is fed through the plug 9
It is blown out from the orifice 9a into the connecting hole 4a of the output shaft 4. A plurality of radial lubricating ports 10 are provided on the front side of the output shaft 4, and the lubricating oil supplied via the intermediate shaft 3 is blown out into the extension housing. A rear cover 11 is fitted close to the outer periphery of the lubricating port 10. As shown in FIG. 2, the details of the rear cover 11 are as follows: The main body 11a has a substantially cylindrical shape, and is fitted onto the output shaft 4 with a flange 11b at the front end and a partition wall 11c at the rear end. have. Flange 11
b is located forward of the lubricating port 10, and its peripheral edge is press-fitted into the housing wall 1a. Partition wall 11
C is located at a portion of the output shaft 4 that has a smaller diameter than the rear bush bearing surface, and a notch 11d that slides into contact with the outer periphery of the output shaft 4 is provided. A through hole 11e for introducing lubricating oil into the extension housing is provided on the upper surface of the main body 11a at a position facing the lubricating port 10 of the output shaft 4. The notch 11d is brought into sliding contact with the outer periphery of the output shaft 4, and the main body 11a is inserted therethrough.
When the flange 11b is press-fitted into the housing wall 1a, the lower part of the extension housing 1 is surrounded by the rear bushing 7, the rear cover 11, and the housing wall 1a, and the oil level is lower than the bearing of the rear bushing 7. An oil reservoir 12 is formed that extends beyond the lowest part 7a of the surface.

の耐久性が向上する効果がある。 Since this invention is a bearing lubricating port cover having the structure described above, the lubricating oil blown out from the lubricating port of the driven shaft element is prevented not only during normal driving but also at low vehicle speeds and at low temperatures. The lubrication of the sliding bearing of the driven shaft element is achieved by freely diffusing into the extension housing and storing enough lubricating oil in the oil sump below that the oil level exceeds the bottom of the bearing surface of the sliding bearing. This has the effect of improving its durability.
