Abstract
A removable wheel device includes a wheel unit, a housing, and a locking unit. The wheel unit includes a wheel body and a wheel axle formed with an annular groove. The wheel axle is extendible removably into the housing. The locking unit includes an actuator connected pivotally to the housing, an elastic member mounted between an operating end portion of the actuator and the housing, and a locking pin connected to a force transmitting end portion of the actuator. The operating end portion is depressible to move the force transmitting end portion from a locking position, where the locking pin extends into the annular groove to prevent removal of the wheel axle from the housing, to an unlocking position, where the locking pin is disengaged from the annular groove to permit removal of the wheel axle from the housing.
