Claims

[Claims for Utility Model Registration] (1) In a self-propelled simple vehicle equipped with at least one fixed wheel whose wheel direction is fixed and at least a pair of left and right variable direction wheels whose wheel direction can be changed. A self-propelled simple vehicle, characterized in that a steering handle is connected to one of the variable direction wheels so that this variable direction wheel is used as a steered wheel, and the other variable direction wheels are used as adjustable legs. (2) The self-propelled simple vehicle according to claim 1, wherein one of the fixed wheels is a drive wheel driven by a drive mechanism. (3) The vehicle is a wheelchair equipped with a pair of hand-operated main wheels on the left and right as fixed wheels at the rear, and a pair of variable-direction wheels on the left and right at the front, and the vehicle is steered by one of the variable-direction wheels. A self-propelled simple vehicle according to claim 1 of the utility model registration claim, in which a handle is connected. (4) The self-propelled simple vehicle according to claim 3, wherein both of the pair of variable direction wheels are adjustable wheels. (5) A driving wheel, which is a third fixed wheel, is provided between the manually operated main wheels, and a driving mechanism is provided to drive this driving wheel, so that the grounding point of the driving wheel is the same as the grounding point of each main wheel. A self-propelled simple vehicle according to claim 3 or 4 of the utility model registration claim, which is arranged so as to be located in the center. (6) The self-propelled simple vehicle according to claim 2 or 5, wherein the drive mechanism is a foot pedal type drive mechanism.
