Abstract

PURPOSE:To provide a motor-driven type handcart which is highly practical and whose operation is easy and whose structure is simple, by providing in the vicinity of the hand grip portion of a handcart handle a switch to conduct a travel mode changeover, providing, at the same time, a control lever within the range of hand grip operation. CONSTITUTION:At the time of use, advance and retreat are selected by means of a switch 7 for the travel mode changeover of a hand push handle 8, and when a control lever 9 is grasped together with the hand push handle 8, a parking brake is released, and a volume switch is made ON, and a motor 5 is rotated, and a drive wheel 3 is driven by its decelerated output. When travel speed increase is desired, the control lever 9 is pulled on this side, then a variable resistance in the volume switch is operated according to its stroke quantity, and speed control can be conducted steplessly. Also, when stop is desired, by separating fingers from the control lever 9, the volume switch is made OFF by means of springs 13, and a handcart body is stopped together with the motor 5.
