A pad for a steering wheel includes a membrane switch forming member and a cover member. The switch forming member includes a switch body and a support plate. The switch body has a plurality of conductive thin metal sheets and an insulating space interposed between the metal sheets. The support plate is made of rigid synthetic resin for supporting the switch body on its upper face and is formed in its outer peripheral edge with a plurality of mounting holes extending vertically. The cover member covers the air bag of an air bag device and is formed with a rupture portion adapted to be ruptured when the air bag is inflated, and mounting ribs projecting from the back face thereof and engaged with the mounting holes of the support plate. At least one of the outer peripheral edge of the support plate and the back face of the cover member is formed with gap regulating projections for setting a predetermined gap between the upper face of the support plate back face of the cover member.
