車用の前後進切り換え装置。 A forward driving rotary body 15 and a backward driving rotary body 16 are fitted onto one transmission shaft 12 so as to freely rotate while rotating in opposite directions to each other, and can freely engage with the forward driving rotary body 15. A driven rotating body 17 for forward movement
and a reverse driven rotating body 18 that can freely engage with the reverse driving rotating body 16 are movable along the axial direction of the transmission shaft 12.
a pair of forward/reverse switching operation members 20, 21 that are fitted to rotate integrally with each other and move the pair of driven rotating bodies 17, 18 along the axial direction of the transmission shaft 12; Rotating body 15,1
6 and an actuator 46 for operating the pair of operating members 20, 21 so that one of the driven rotating bodies 17, 18 is in the engaged state and the other is in the disengaged state. It is a forward/reverse switching device, and the drive rotating body 15
, 16 and the driven rotating bodies 17, 18 are in an interlocking state with respect to the pair of operating members 20, 21.
The elastic biasing means 26 elastically biases the operating members 20 and 21 between a state in which one of the pair of operating members 20 and 21 is biased toward the occlusal state and a state in which the other is biased toward the occlusal state. A forward/reverse switching device for a working vehicle that is provided to be switched in accordance with the operation of an actuator 46.
