<p>An instrument panel integrally including an airbag door that may make door opening performance excellent even when a cross-sectional shape of a door main body portion of the airbag door as viewed in a vehicle width direction is formed in a recessed shape that curves so as to recess toward the opposite side thereof from a vehicle cabin, and a curvature direction one side door portion and curvature direction other side door portion that are specified in the door main body portion open to the vehicle cabin side about hinge line portions at the sides of the two ends in the direction of curvature. In this instrument panel, a groove portion (68) for forming an intended splitting portion (70) in the door main body portion (24) of the airbag door (16) is formed at a cover layer (62) side of the door main body portion (24). Therefore, when the door main body portion (24) inverts from the recessed shape to a protruding shape due to inflation pressure of an airbag (58), the groove portion (68) is stretched in the curvature direction of the door main body portion (24). As a result, stress arising at the intended splitting portion (70) is dispersed, and splitting of the intended splitting portion (70) before the door main body portion (24) has completely inverted to the protruding shape is prevented. Therefore, unintended interference between a front side door portion (24C) and a rear side door portion (24D) may be prevented.</p> |
