An upper coupling groove(11a) and a lower coupling groove(11b) are formed on both ends of the body. The body detachably coupled to an operating unit through the upper coupling groove. The connecting member is detachably coupled to the lower coupling groove of the body. The striking member is inserted into the front side of the connecting member. The striking member is formed from a material, which can apply load by striking the impact point of the door trim in operation of the operating unit and prevent the metallic noise generation in striking of the impact point.
