Abstract
A steering wheel for an automobile is provided. The steering wheel comprises: two surface elements, each formed by stacking a decorative layer and a reinforce layer, joined together at seams; a core material layer disposed to the inside of the surface elements; a metal core disposed to the inside of the core material layer, the surface elements, the core material layer, and the metal core being integrated to form the steering wheel; and fiber reinforcing layers which are provided between the reinforce layer and the core material layer, and which bridge one surface element and the other surface element across the seams of the surface elements. The fiber reinforcing layers are made of material selected from glass fibers, carbon fibers, aramide fibers, and metal fibers. Fibers having lengths of at least 25 mm are scattered in the core material layer. Accordingly, the stress concentration at the seams due to thermal expansion of the core material layer can be prevented, and, cracking, along the seams, in the coating film formed on the surface of the decorative layers can be prevented.
