<p>PURPOSE:To simply and surely release locking and remove a cover by providing a guide part, which releases the hold of a mobile arm and also guides a cover so as to separate it from the body, at the projection on cover side. CONSTITUTION:When a lock member 20 is slid in lock condition, a mobile arm (lock arm) 30 is bent and deformed by the guide parts 19a and 19b of the salient wall 19 on cover side, and the engagement between a cover 14 and the body 12 is released. And, when the lock member 20 is further slid, the wedge part 33 of the mobile arm 30 cuts in between the salient wall 17 on body side and the salient wall 19 on cover side by the elastic restitutive force of the mobile arm 30, and the force of pulling the cover apart from the body 12 occurs by its wedge action, and the cover 14 is pulled apart from the body. Hereby, the release of the lock and the removal of the cover can be performed simply and surely merely by operating it from above (as indicated by the arrow).</p> |
