<p>PURPOSE:To provide a steering wheel with which the outside apperance is improved and the slip in operation is prevented, and the seaming work in winding leather on a ring part can be carried out easily. CONSTITUTION:A steering wheel is formed by gradually changing the inner peripheral side of a ring part R so that the thickness of the ring part R in plan view is reduced by forming small diameter parts 11, 12, 13 and 14 at four places in the longitudinal and lateral directions of a vehicle, and increasing the thickness by forming the large diameter parts 15, 16, 17 and 18 at four places in the intermediate part in the longitudinal and lateral directions of the vehicle.</p> |
