摘要： PROBLEM TO BE SOLVED: To detect a rotation angle with high accuracy by eliminating a conventional backlash between a rotor and a driving gear. SOLUTION: An energizing member 50A exerts an energizing force in the direction of β2 on the driving gear 36 and an energizing force in the direction of β1 on an auxiliary gear 40. This eliminates a backlash between the rotor 13 and the driving member 36, and thus play can be reduced between the rotor 13 and the driving member 36. The rotation of the rotor 13 can be efficiently transmitted to the driving gear 36, and a rotation angle of a steering wheel Sh mounted with the rotor 13 can be detected with high accuracy.
