作業の煩雑化を招く。 Conventionally, most of such tricycles have adopted a chain and sprocket mechanism, but it is planned to adopt a shaft drive mechanism instead.
By the way, the shaft drive type is equipped with a gear case to protect the final gear mechanism, and on the other hand, the axle must be rotatably supported on the frame side as a drive shaft, and on the other hand, the axle must be equipped with a brake device for braking. However, if these support structures and the like are provided individually, there is a risk that the structure will be complicated, the number of parts will increase, the assembly work will be complicated, and there will be disadvantages in maintenance. In addition, since this type of tricycle travels on muddy areas, it is necessary to make each part waterproof and dustproof. If each part was independent and provided with a sealing mechanism, the number of parts would increase, the structure would become complicated, and the assembly would be difficult. This leads to complicated attachment work.
