Structure and method for mounting damper

摘要

A damper attaching structure which enables a damper provided with a thin rotational shaft to be assembled inside a casing or the like by employing an opening formed in the casing, is obtained by providing a concave groove which is formed in the inner surface of wall member and which is continuous from a casing opening; a positioning plate provided at the base of a damper thin shaft on the damper side thereof; a shaft hole which opens at the concave groove and which is larger than the cross section of the damper thin shaft; and a shaft fixing member which is provided on a lever, and which has an engaging hole into which the damper thin shaft is inserted and which engages the damper thin shaft member to enable torque transmission, and rotatably inserted into the shaft hole. The concave groove has a larger shape than the positioning member, the positioning member is inserted into the concave groove at the attachment position of the damper, and the positioning member adjusts the position of the damper along the shaft direction by intersection with the concave groove at the rotation position of the damper.
