Abstract: A steering wheel deice comprising: a horn spring provided between a steering wheel and an airbag module which serves as a damper mass; a damper unit provided on the airbag module; and a pin, one end of which is held by the steering wheel, and at another end of which the damper unit is disposed in a slidable manner. A conduction circuit of a horn includes: the pin which is formed from an electrically conductive material; a horn contact that is provided on the airbag module and that contacts and separates from the pin due to elastic deformation of the horn spring; and a U-shaped spring that is provided to the steering wheel and that conducts by clipping the pin.

Abstract: Providing of a gripping determination system and gripping determination method enabling detecting whether or not the driver is gripping the steering device with higher accuracy.
A gripping determination system that determines a gripping state of a steering device having an electrode on a part of a steering device of a vehicle, includes:



an electrostatic capacitance detecting part that detects electrostatic capacitance of the electrode,
a steering torque sensor that detects steering torque of the steering wheel shaft, and
a determining part that determines whether or not the steering device is being gripped based on detection results of the electrostatic capacitance detecting part and the steering torque sensor.
