Claims

[Scope of utility model registration request]

A traveling work vehicle is equipped with a side clutch 3 that is disengaged by a sliding displacement operation of a clutch gear 4, and a multi-plate hand brake 10 that is activated after the side clutch 3 is disengaged.
In the handbrake 10, the pressure receiving body 21 against which the friction plate 11 and the group of mating plates 13 are pressed when the brake is activated can be slidably and rotationally displaced from a regulated position in the direction of the friction plate 11 and the group of mating plates 13. A cam slope 2 inclined along the circumferential direction is provided between the pressure receiving body 21 and the mission case wall 16.
A ball 26 is provided within the cam grooves 24 and 25 having the cam grooves 4a and 25a, and the pressure receiving body 21
The rotational displacement of the pressure receiving body 21 is operated via the ball 26.
The operation tools 27 and 28 are slidably displaced in the direction of the friction plates 11 and the mating plates 13 to bring the friction plates 11 and the mating plates 13 into frictional engagement when the side clutch 3 is fitted. Further, a pressing portion 4a for operating the handbrake 10 by pressing the friction plate 11 and the group of mating plates 13 toward the pressure receiving body 21 after the side clutch 3 is disengaged is provided on the clutch gear 4. A brake device characterized by being integrally formed with.
