PURPOSE:To increase the appearance quality of an entire steering wheel by forming a square folded part, connected to a triangular folded part, and increasing the number of folded layers on the square folded part more than that on the triangular folded part. CONSTITUTION:A part where an air bag 1 is overlapped is 6-layer at the upper side and 4-layer at the lower triangle part 1c. The lower triangle part 1c is most twisted at the right angle top and, in actual, its thickness becomes 4-layer or more. First the thickness of the air bag 1 after folding becomes mostly even. Second the air bag 1 of flat circular form can be folded in pentagonal form 1beta. By these two actions, when the air bag 1 is stored under the pad 16 of an air bag device 100, the air bag device 100 is prevented from becoming large and the pad 16 can be made in pentagonal form. becoming large and the pad 16 can be made in pentagonal form. Thus, when the air bag device 100 is installed on a three-spoke steering 12, the appearance quality of the entire steering wheel 12 is increased. |
