摘要： An automobile airbag door is formed by a door base member, a door cover member, and a tear line. The door base member and the door cover member form a part of a base member and a part of a cover member of an instrument panel, respectively. When pressed by an airbag being deployed and inflated, the door base member is torn from the tear line. The first zone is defined as the bonded part between the outer surface of the door base member and the door cover member which extends along the tear line and includes a part on which the tear line is projected. The second zones are on both sides of the first zone and extend along the tear line. The automobile airbag door has a mechanism that makes the bond strength in the first zone weaker than the bond strength in each second zone.
