An active knee bolster ( 28 ) and a knee bolster ( 42 ), whose accommodated positions are different, are mounted within an instrument panel ( 18 ) along a curved configuration of a wall portion ( 24 ) of the instrument panel ( 18 ) which, in a vehicle transverse direction, is convex and concave in a vehicle body longitudinal direction. At a time of a vehicle body collision, a main body ( 30 ) of the active knee bolster ( 28 ) moves from an accommodated position to a leg restraining position, and a leg restraining position of the active knee bolster ( 28 ) and a leg restraining position of the fixed-type knee bolster ( 42 ) become equal positions in the vehicle body longitudinal direction. In accordance with this invention, legs of an occupant can be reliably protected, and degrees of freedom in designing a vehicle interior wall such as the instrument panel or the like are improved.
