Abstract: A steering wheel enabling suppressing hanging down of an airbag module due to its own weight and stabilizing the position of the airbag module. The steering wheel includes a steering wheel body, an airbag module, and at least one coil spring that biases the airbag module in a direction separating from the steering wheel body. The coil spring is arranged between the steering wheel body and the airbag module in a state with the axis line thereof offset from that of a free state; thereby applying a force on the airbag module in a direction that intersects with the axis line of the coil spring in a free state.
