Claims

[Claims for Utility Model Registration] 1. A rotor that rotates in conjunction with a steering wheel, a deceleration rotating body that is provided coaxially with the rotor and to which the rotation of the rotor is transmitted via a deceleration mechanism, and the rotor and the deceleration rotation. The deceleration mechanism is equipped with a signal generation means for generating an angle signal corresponding to the relative rotation angle between the bodies, and a slip ring device for extracting the angle signal from the signal generation means through the deceleration rotating body. The reduction ratio is set such that the relative rotation angle between the rotor and the reduction rotating body is 36
A rotation detection device for a steering wheel for an automobile, characterized in that the rotation detection device is set to a value that is 0° or less. 2. The speed reduction mechanism is characterized in that it is configured as a gear mechanism including a drive gear and a driven gear formed around the rotor and the speed reduction rotating body, respectively, and an intermediate gear interposed between these gears. A rotation detection device for a steering wheel for an automobile according to claim 1 of the utility model registration claim.
