<p>PROBLEM TO BE SOLVED: To facilitate the removal of a cover, and firmly mount and fix the cover to a body with no mounting bolt used. SOLUTION: An air bag cover 26 is mounted and fixed to a body 1 in such a way that a housed-in air bag is enclosed, and the cover is pressed so as to be opened in such a way as to be projected out when the air bag is expanded. A locking leg 30 is disposed, provided with plural pawl pieces 31 to be inserted into a locking hole 2a provided for the body 1 so as to be locked around the circumferential periphery of the locking hole 2a on the back surface side of the body 1 in such a way as not to be pulled out. The respective pawl pieces 31 of the locking leg 30 are guided to the circumferential periphery of the locking hole 2a, when they are inserted therein in the insertion direction toward the locking hole 2a, they are so constituted as to be provided with contraction guiding parts 34 and 34 capable of maintaining an approaching condition wherein the pawl pieces 31 and 31 are mutually approached together while being guided to the circumferential periphery of the locking hole 2a.</p> |
