Abstract
A steering angle sensoris provided which can minimize a detection error even when a steering shaftis inclined. In an annular clearance tdefined between the steering shaftand an inner cylindrical wall of a first gear, there is compressed an elastic O-ring. Due to provision of the elastic O-ring, inclination of the steering shaft, which tends to occur during handling of a steering wheel, is suitably absorbed by the elastic O-ring, and thus, generation of detection error caused by inclination of the first gear, which would follow the inclination of the steering shaft, is suppressed or at least minimized.
