The stem 5 is formed with hook portions having retaining portions respectively for engagement with retaining grooves formed in the inner side faces of the housing, the hook portions 5d being respectively formed with relief portions on sides thereof opposed to the rubber spring 4 to receive therein bent portions of the rubber spring. <IMAGE>
