Abstract: [Problem] To enable an airbag module to be assuredly assembled to a cored bar.
[Resolution Means] The present invention is applied to a steering wheel including: a cored bar member; and an airbag module which houses an airbag cushion and an inflator and is coupled to the cored bar member via a coupling pin, wherein the steering wheel employs a configuration in which the coupling pin extends from the airbag module side to the cored bar member side. The steering wheel according to the present invention includes: a coil spring arranged outside the coupling pin; and a support member supporting the upper end of the coil spring at a peripheral part of the coupling pin. Moreover, the support member includes a hook which includes: a support surface protruding in the direction vertical to the shaft of the coupling pin in order to support the upper end part of the coil spring; and a side extending from this support surface towards the lower side of the coupling pin. In addition, the coil spring is configured so as not to interfere with the side of the hook.

Abstract: A steering wheel is disclosed enabling suppressing unnecessary rocking of the airbag module during airbag activation and thereby ensures prescribed deployment performance of the airbag cushion. In detail, the steering wheel is provided with a core metal having a boss part configured so as to be mountable on a steering shaft and an airbag module movably provided with respect to the core metal and having an airbag cushion that can be expanded and deployed. The stopper of the core metal is separated from the stopper contact part of the airbag module in a non-activated state of the airbag, and comes into contact with the stopper contact part due to movement or deformation of the airbag module caused by expansion and deployment of the airbag cushion during activation of the airbag.

Abstract: A steering wheel includes a steering wheel body, an airbag module, and a damper unit that connects the steering wheel body and the airbag module. The airbag module is mounted to the steering wheel body via the damper unit facing in a Z-axis first direction that is an example of a first direction. The damper unit is configured to apply a force on the airbag module in a state where the airbag module is mounted on the steering wheel body in a direction of pushing up the airbag module in a direction that intersects with the Z-axis first direction.
