出装置。[Claims for Utility Model Registration] A shaft rotation conversion mechanism that converts the rotation angle of a steering shaft caused by rotation of a steering wheel into a predetermined rotation angle, and a rotation angle obtained through the shaft rotation conversion mechanism using an electrical signal. The steering shaft includes a steering wheel rotation angle sensor for detecting the rotation angle, and the steering shaft has an oil passage switching valve section that is a valve dead zone in a neutral position region, and a metering section that sends oil in an amount proportional to the rotation angle. A steering wheel rotation angle detection device provided with a steering unit, characterized in that the shaft rotation conversion mechanism is provided with an adjustment that substantially corresponds to a valve dead zone of the steering unit.
