The output shaft (5) is connected to the interlocking mechanism via the connecting shaft 071, the input shaft (8), and the clutch, and further to the left and right rear axles (Ql) via the axle.
) to rotate the cooling fan (g) via the bell +-en. The cooling air generated by the rotation of the cooling fan 0 is sucked from around the suction hole 03 QJ and the clutch housing (9) to the rear part of the radiator@, and passes through the inside of the radiator (20). The cooling water that circulates around the engine is cooled and flows forward inside the bonnet (4) while cooling the outer periphery of the engine, turning into hot air and being discharged from the front of the bonnet to the outside of the bonnet.

A spur gear [phase] is provided and fixed inside, and this input shaft (8)
Two interlocking shafts I supported on the front wall of the interlocking case 0@ are provided on the lower side of the interlocking case 0 so as to protrude forward.
, a rotatable clutch body 0 is provided which has teeth that mesh with the spur gear (c) and a friction surface on the front side of the teeth, and a front shaft of this clutch body (4) ``Secondly, a clutch plate OD pressed against the friction surface by a spring is provided to be slidable and non-rotatable, and furthermore, a clutch plate OI) is provided on the shaft (c) on the front side of this clutch plate 011. A sliding body 0 is provided which can release the pressure on the friction surface by moving in the axis 0 direction, and this clutch housing (9)
A housing cover (111) is provided on the lower side of the input shaft (8) to cover the open part of the front part of the housing (9). A shifter (b) that can move in the axis 0 direction against a spring is provided and supported.

(c) will be interlocked with the interlocking mechanism to the left and right rear wheels QυQO, etc. Also, when the shifter (b) is operated, the clutch plate OD's clutch body ((+
) is removed and the clutch plate becomes 0.
Since the frictional force between ◇ and the clutch body ■ disappears, the interlocking movement from the clutch body 61) to the clutch plate 0◇ is cut off.

When the shifter (
(b) and sliding body) are both removed from the interlocking shaft (c), so the clutch plate 00 can be taken out forward from the interlocking shaft O. Also, when assembling, this order can be done in the reverse order; When replacing the clutch plate 0D, it is possible to easily and easily replace the clutch plate 0D without requiring operations such as moving the fuselage back and forth.
