PURPOSE:To shorten the fabrication time of fragile sections in a steering wheel, by bending each fragile section at the boss side thereof at an obtuse angle with respect to the radial direction of the boss to prevent work hardening from occurring during molding the fragile sections. CONSTITUTION:Three fragile arm sections 5 are integrally incorporated with a boss attaching section 2, and are radially formed. The boss attaching section 2 and the end part side of each fragile section 5 are welded to a notch part in the upper end section of a boss 1 and the lower surface of a spoke attaching section 3, respectively. Each fragile section 5 is bent at the boss attaching section 2 side at an obtuse angle with respect to the radial direction of the boss 1, and is also bent at its spoke attaching section 3 side in a crank-like shape.
