とを特徴とする。 Generally, a gear case is provided around the rear axle of a tricycle to protect the final gear mechanism, one axle is rotatably supported by the vehicle body as a drive shaft, and the other axle requires a brake device for braking. For this reason, it becomes complicated to attach the gear case and the brake case to the vehicle body, and it is also difficult to attach and disassemble the rear axle to these two cases. The present invention aims to improve such disadvantages, and the final transmission gear and the brake drum, which are disconnected from the rear axle by movement of the axle in the axial direction, are arranged in a transmission case and a brake case, respectively. The present invention is characterized in that both cases are integrally connected and fixed to the vehicle body, and the rear axle is detachably attached to both cases.

固定されている。 To explain this with reference to the illustrated embodiment, the figure shows a tricycle for rough terrain using balloon tires 1,
The power of the engine 3 attached to the center of the vehicle body 2 of the tricycle is transmitted to the final drive mechanism 5 via the propeller shaft 4, and the drive mechanism 5 meshes with a pinion gear 6 connected to the shaft 4, and It consists of a ring-shaped final transmission gear 8 that engages with the rear axle 7 by spline, and a transmission case 9 that houses these gears supports the final transmission gear 8 via a bearing 10 and a dust seal 11, and oil is contained in the case 9. It is formed in a sealed case that encloses the 12 indicates a braking mechanism attached to the rear axle, and the mechanism 1
2 consists of a brake drum 13 spline-engaged with the rear axle 7, a brake shoe 14 inscribed in the drum 13, and a brake cam 15 for opening and expanding the shoe 14, and a brake case 16 that houses these components. A shaft cylinder protruding from one side of the center of the brake drum 13 is pivotally supported via a dust seal 11, and a collar 17 that abuts the shaft cylinder protruding from the other side of the center of the drum 13 is supported between the bearing 10 and the dust seal 11. The case 16 has a space 18 and is integrally fixed to the conductive case 9 side by side via a coupling bolt 19, and both cases 9, 16
is attached to a bracket 20 provided on a rear support pipe 2a of the vehicle body 2 via a through bolt 21. The rear axle 7 is inserted from the gear case 9 side of both cases 9 and 16, and is secured to one side of the case 9 by a stop piece 7a formed on the outer periphery of the rear axle 7, and a screw 7b formed on the outer periphery of the insertion end. The rear axle 7 is fixed to these cases 9 and 16 by tightening the collar 17 with a nut 22 that is screwed together.

剛性を高めて軽量化できる等の効果を有する。 According to the present invention, the final transmission gear 8 and the brake drum 13, which are disconnected from the rear axle 7 by axial movement of the axle 7, are supported by the transmission case 9 and the brake case 16, respectively. At the same time, both cases 9 and 16 are integrally connected and fixed to the vehicle body 2, and the rear axle 7 is detachably attached to both cases 9 and 16, so that it is easy to remove the rear axle during disassembly and assemble it. Moreover, since the transmission case and the brake case are integrated, the area around the rear axle can be made compact, and the rigidity can be increased and the weight can be reduced.
