ABSTRACT:
A claw extends from a tubular-shaped housing wall which is a part of a casing member to a retaining hole formed in a tubular-shaped fitting wall of the casing member, and is retained by an edge portion of a projection extending from a retaining wall hole to the inside of the retaining hole. When force generated by the air bag held in the casing member operates on the casing member, the claw pushes the projection toward an opening end side of the tubular-shaped fitting wall. However, since the projection extends from the center portion of the retaining wall into the retaining hole, the projection is only crushed toward the opening end side of the tubularshaped fitting wall, and the bottom side of the claw does not directly contact with the retaining wall of the retaining hole if the claw pushes the projection. Therefore, the retaining wall is not cracked at both sides of the projection; and the cover member does not separate from the casing member, and the air bag can be inflated smoothly.
