Abstract: A rotary shade is disposed behind a projection lens to block a portion of light emitted from a light source. The rotary shade has a twisted end surface to form an edge projected as a peripheral edge of a light distribution pattern which changes position in relation to the rotation of the shade. The twisted end surface is arranged so that the closer the twisted end surface is to the projection lens the more the twisted end surface approaches the optical axis. The twisted end surface moves from the front to the back of a rear focal point in relation to the rotation of the rotary shade in the direction in which the illumination area of the light distribution pattern increases.

Abstract: In this instrument panel, a groove portion for forming an intended splitting portion in the door main body portion of the airbag door is formed at a cover layer side of the door main body portion. Therefore, when the door main body portion inverts from the recessed shape to a protruding shape due to inflation pressure of an airbag, the groove portion is stretched in the curvature direction of the door main body portion. As a result, stress arising at the intended splitting portion is dispersed, and splitting of the intended splitting portion before the door main body portion has completely inverted to the protruding shape is prevented. Therefore, unintended interference between a front side door portion and a rear side door portion may be prevented.
