Therefore, the parking brake is separated from the transmission portion into a unit, and the structure is simplified. You can do it. Further, the parking brake mechanism 10 can be sub-assembled separately from the gear mechanism inside the transmission, and then can be assembled to the transmission case 8c in the main line of the assembly conveyor. In addition, since the stopping gear 13 is also engaged and connected with one of the gears forming the gear speed change mechanism 8a, it is compared to the conventional work of engaging the spline formed between the friction plate and the shaft hole of the friction plate. As a result, it is easy to assemble and it is possible to prevent the length of the assembly conveyor from increasing. Therefore, there is an effect that the shortening of the assembly conveyor and the productivity improvement of the assembly work can be achieved at the same time.
