ABSTRACT:
A mechanism for covering a casing accommodating an air bag therein is formed of a lid for covering the casing, mounting pieces protruding from a back surface of the lid for mounting the lid to the casing, and high strength portions. First and second tear lines are formed in the back surface of the lid to allow the lid to be torn along the first and second tear lines. The first tear line extends in the width direction of a vehicle, and the second tear lines intersect the first tear line. The high strength portions are disposed outside the second tear lines near the respective connecting corners between the first tear line and the second tear line. The high strength portions are ribs, which are disposed on the back surface of the lid and project such that the second tear lines extend along the ribs. The ribs continue from the mounting pieces to thereby prevent a tear, which has traveled along the first tear line, from further traveling sideways at the connecting corners.
