A stator and a rotator, which relatively rotate concentrically with a steering, are formed. A torque transmitting portion, which transmits a rotation torque of the steering to an angle detection rotating body provided in an angle detection sensor for detecting a rotation angle of the steering, is formed concentrically with the angle detection rotating body. Fitting portions for fitting to fitting allowance portions, which are formed on at least a part of a circumferential direction of the angle detection rotating body, are formed on the torque transmitting portion. Fitting abutting portions of the fitting portions, which fit and abut against the fitting allowance portions, are formed in shapes tapered toward the fitting allowance portions.
