VEHICULAR AIRBAG DEVICE

A vehicle airbag device includes an inflator, a bag shaped airbag cushion, and a rectifying member on the inside of the airbag cushion. The rectifying member includes a bottom surface part into which the inflator is inserted, a roof part that, when a rim of a steering wheel is likened to a dial of a clock, extends in a 12 o'clock and 6 o'clock direction on the clock when seen from a driver regularly seated in a driver seat with the steering wheel in a neutral position, and opening parts and formed in the 12 o'clock and 6 o'clock positions. The roof part includes, when seen from a 9 o'clock direction, a top part that protrudes convexly toward a driver side, and ridge line parts and that extend in both the 12 o'clock and 6 o'clock directions of the clock from the top part in an inverted arch shape.
