winkelsensor, which rattles through the game between gears within the winkelsensor is prevented

摘要

An angle sensor in which, when a biasing member is used, a biasing force in the beta2 direction acts on a driving gear, and a biasing force in the beta1 direction acts on an auxiliary gear. This prevents backlash from occurring between a rotary member and the driving member, making it possible to reduce rattling between the rotary member and the driving member. A fitting member is provided at the free end side of a resilient supporting member in order to resiliently press a screw shaft in the Z1 direction. Therefore, internal threads of inside surfaces of corresponding fitting portions of the fitting member and thread grooves of the screw shaft can be made to uniformly closely contact each other, making it possible reduce rattling caused by backlash therebetween. Consequently, the angle of rotation of a steering wheel which is mounted to the rotary member is detected with high precision.
