To switch a connected/unconnected state of left/right brake pedals without stopping travel by putting the left/right brake pedals in an unconnected state when an electric means is put into an ON-state, and putting the left/right brake padals in a connected state when the electric means is put into an OFF- state.
When turning on a brake pedal connecting changeover switch, an electric current flows to a connecting solenoid, a connecting pin 15a contracts, left/right brake pedals 13a, 13b are put into an unconnected state, and when turning off the brake pedal connecting changeover switch, the electric current does not flow to the connecting solenoid, and the connecting pin 15a extends to connect the left/right brake pedals 13a, 13b. Thus, when switching a connected/unconnected state of the left/right brake pedals 13a, 13b, the state can be switched without stopping travel by simple operation only by turning on and off the, brake pedal connecting changeover switch.
