Abstract: A steering wheel includes a boss, two spokes supported at the boss, a grip fixed to each spoke, and a rotation control mechanism arranged between the boss and each spoke. The rotation control mechanisms are each configured to define a maximum rotation angle by which each grip is rotated from the neutral position in a near-side direction and a maximum rotation angle by which each grip is rotated from the neutral position in a far-side direction. The rotation control mechanisms are each configured to return each grip to the neutral position when a vehicle is traveling straight. The maximum rotation angle in the far-side direction is set to be larger than the maximum rotation angle in the near-side direction in each rotation control mechanism.
