- the airbag device 30 is pressed toward the steering wheel 10 so that each attachment member 18 is inserted into the corresponding holding member 60. Then, the inclined surface 22a at the tip of the attachment member 18 contacts the locking body 70 (see FIG. 15). Then, the locking body 70 is elastically deformed by the inclined surface 22a so as to be pushed toward the inside thereof. And if it exceeds the latching protrusion 18b and the disengagement prevention convex part 27a of the attachment member 18, the latching body 70 will elastically return (refer FIG. 16).
