を施されて閉じるようにした。 The shock absorber 8 is of a type in which a front half 8a spline-engaged with the propeller shaft 9 and a rear half 8b spline-engaged with the input shaft 7 are pressed against each other by a front spring 8c. The outer case 11 is made up of a cylindrical frame housing which is elongated in the front-rear direction on its outer periphery, and is attached to the shaft 9 at its front end so as to rotate together with the outer case 11. The rear end portion thereof is fitted and supported by the rear half portion 8b via a front guide ring 14 made of nylon and a rear seal ring 15 made of rubber. Further, the input shaft 7 is connected to a bevel gear 16 on the axle 3a of the rear wheel 3.
It consists of a pinion shaft extending forward integrally from a pinion 17 that meshes with the pinion shaft, and a spherical hand type universal joint 10 is interposed between the outer periphery of the pinion shaft and the rear half portion 8b. In the drawing, 18 indicates a gear case on the outer periphery that accommodates these,
The above-mentioned outer cover 12 is provided on its inner periphery, and an oil chamber 1 is provided therein by front and rear seal rings 19, 19.
2a is formed, and the inside of the oil chamber 12a is connected to the outer case 1 through the communication passage 13 described above.
I tried to keep it within 1. More specifically, the communication passage 13 has a radial through hole 13a that communicates with the oil chamber 12a and extends inward, and a central axis within the pinion shaft 7 that communicates with this and extends in the front-rear direction. The inside of the shaft hole 13b is connected from the front open end thereof to the outer circumferential portion of the outer case 11 described above through the side through hole 13c, and in parallel thereto, the inside of the propeller shaft 9 described above. The shaft hole 13d is connected to the inner peripheral portion of the case 11 through a hole 13d at the center thereof and a through hole 13e on the side thereof. In the drawings, reference numeral 21 indicates an oil supply port formed in the case 18 to introduce oil from the outside to the oil chamber 12a in the cover 12, and the oil supply port 21 is normally connected to the oil bolt 20.
