使用できる。 When meshing the input gear 27 of the side clutches 29A and 29B, which need to have a large diameter for deceleration, with the driven gears G3 and G4, the gear diameter of the large gear 27 is not affected by the outer diameter of the hydraulic clutch. There is a large degree of freedom in designing the reduction ratio. Therefore, as in the embodiment (Fig. 3), the diameter of the large gear 27 can be made large so that it fits between the hydraulic clutches, and the diameter of the driven gear can be made small, and even with this gear engagement, a large deceleration can be obtained. , the hydraulic clutch operates at a relatively high rotational speed without requiring unreasonable deceleration between the input shaft and the hydraulic transmission shaft, and a clutch with a small torque transmission capacity can be used.
