Abstract:
A rotor (1b) includes a first cylindrical portion (10), and a second cylindrical portion (20) including a first partial circumferential surface (21) having a width narrower than that of the first cylindrical portion (10) in the circumferential direction, and a second partial circumferential surface (22) having a radius smaller than a radius of the first partial circumferential surface; the rotor, further, including a first to-be-detected portion having a plurality of teeth (15), and a second to-be-detected portion having at least one tooth (25), and wherein the at least one tooth of the second cylindrical portion and the tooth of the first cylindrical portion corresponding to the at least one tooth are formed in one operation by machining.
