- 摘要:
PROBLEM TO BE SOLVED: To provide a working vehicle having a structure changing the change gear ratio of a continuously variable transmission by an gear change actuator by the operation of a gear change pedal and securing travel stability even if an operation abnormality occurs at the gear change actuator.
SOLUTION: The working vehicle includes the continuously variable transmission 21, the gear change actuator 60 changing the change gear ratio of the continuously variable transmission 21 based on an operation quantity of the gear change pedal 16, a brake mechanism 23, a clutch mechanism 22, a mechanical interlocking mechanism changing over the connection and disconnection of the clutch mechanism 22 simultaneously by the operation of the brake mechanism 23 by the operation of a brake pedal 17, a brake apply member 75 bringing the brake mechanism 23 into an operation state, a clutch disconnection member 76 bringing the clutch mechanism 22 into a disconnection state, and a control device 80 bringing the brake mechanism 23 into an operation state by the brake apply member 75 and simultaneously bringing the clutch mechanism 22 into the disconnection state by the clutch disconnection member 76 when the gear change pedal 16 is not operated.
