Module cover for air bag device

摘要

Adapter members are projected from the inner surface of a cover member and tear lines including a first tear line which extends in the transverse direction of the cover member and second tear lines which extend in the longitudinal direction thereof are provided. The second tear lines are disposed at a short distance away from the adapter members. The thickness of portions of the cover member outside the second tear lines is smaller than that of the adapter members. The thickness of a portion of the cover member between the second tear lines is smaller than that of the portions of the cover member outside the second tear lines. Therefore, the tearing operation proceeding along the first tear line changes the course at the intersecting portions with certainty, and proceeds to the second tear lines. Thus, the module cover is torn open exactly along the tear line.
