A form comprising a belt transmission device that continuously changes the speed of a point traveling device by means of a belt, a speed change operation lever that performs a speed change operation of the belt transmission device, a braking mechanism that brakes the traveling device, and a braking body that performs a braking action on the braking mechanism. When braking this braking body on a running vehicle, it is necessary to shift the belt transmission to the low speed side using the gear shift operation lever at the same time or before this operation, but this braking operation is often done in a hurry because it is dangerous. At this time, it is not easy to operate the gear shift lever in a timely manner, and this operation may be dangerous.
