A drive mechanism for a movable toy has a housing and a motor. A control gear which is movable both rotationally and axially is located on the housing and is connected to the motor through a gear train. Rotation of the control gear is transferred to a control element to rotate it. The control element in turn moves the control gear axially to engage or disengage it with an output member. The output member comprises a drive wheel which is mounted in a yoke which is pivotally mounted on the housing. Rotation of the drive wheel moves the toy along a supporting surface. Additionally, the control element is connected to a further output member and intermittently moves the further output member. Movement of the output member and the further output member are coordinated through the control element whereby when the control element engages the control gear, the drive wheel is moved and when the control element disengages from the control gear, the further output member is moved.
