Abstract
Herein disclosed is an air spoiler retracting device which comprises a casing; a reversible electric motor disposed in the casing and having a drive shaft; a carry bar held by the casing and axially movable in parallel with the axis of the drive shaft, the carry bar having one end to which a spoiler proper is connected; a first transmission mechanism including a first gear driven by the drive shaft of the motor and a second gear meshed with the first gear; a second transmission mechanism for converting the rotational movement of the second gear to the axial movement of the carry bar; a pivoting mechanism for permitting a pivotal movement of the carry bar relative to the second transmission mechanism; and a pivoting movement assisting mechanism for assisting the function of the pivoting mechanism, the assisting mechanism including at least one elastomeric member sandwiched between attached two parts.
