To facilitate a coupling work when a vehicle to be towed is coupled to a towing device.
The battery type towing tractor travels with a driving device using a battery as a power source wherein the towing device 1 provided to the rear end 30a of a vehicle body is coupled to the vehicle to be towed for towing. The tractor includes a coupling means 10, 11 provided to the towing device 1, a detecting means 5 for detecting the coupling and decoupling of the coupling means 10, 11, an accelerating means for controlling the travelling, a braking means for performing stop control, and a controlling means 2 for controlling the driving device. The controlling means 2 controls the tractor not to travel without the operation of the accelerating means when the detecting means 5 detects the coupling of the coupling means 10, 11, and controls the tractor to travel at a creeping speed even without the operation of the accelerating means when the detecting means 5 detects the decoupling of the coupling means 10, 11.
