PROBLEM TO BE SOLVED: To prevent the freezing of a stroke switch. SOLUTION: A cab lock switch and a stroke switch 86 are inserted into a control circuit of a motor for driving a pump of a tilting cylinder device 3, and in the case of the tilt-down operation, a cab is locked and the cab lock switch is switched, and thereafter, the driving circuit of the motor is cut by the switching operation of the stroke switch 86 when a stroke of a piston rod 4 becomes the minimum. In a cab tilt device with this structure, the stroke switch 86 is covered with a cover 45 fitted by screwing to a switch plate 40 fixed to the piston rod 4. Since the stroke switch is covered with the cover, adhesion of ice, snow and washing water to the stroke switch is prevented, and even when a vehicle travels in a cold district, freezing of the stroke switch can be prevented, and the wrong operation due to the freezing can be prevented. |
