Original Abstract Submitted
A position detection device detects a position of a rotating body that is provided around a predetermined axis center with respect to a fixed body. A target is fixed to the rotating body. An inductive coil is fixed to the fixed body at a position facing the target in an axial center direction. The transmitting and receiving circuit applies an alternating current to the inductive coil and detects a position of the target. A magnetic circuit section is formed around the axis center and is fixed to the rotating body. A magnetic detection section is fixed to the fixed body and provided in region on a radially inner side than an inner circumferential surface of the magnetic circuit section. The target, the inductive coil, and the receiving and transmitting circuit constitute an inductive sensor, and the magnetic circuit section and the magnetic detection section constitute a magnet-type rotation angle sensor.
