Claims

[Scope of utility model registration request]

A mainspring wound around the outer periphery of the axle, an input clutch that is manually switched and transmits the rotational force of the wheel received from the outside to the mainspring, and the direction of the rotational force of the wheel and the output from the mainspring and the above. A vehicle comprising a direction matching device that matches the direction of the rotational force received by the wheels, and an output clutch that is manually switched to select whether to hold or output the rotational force stored in the mainspring to the wheels.
