The position detection device detects the position of a rotating body (3) provided so as to be capable of rotating or swinging about a predetermined axis (CL) with respect to a fixed body (2), and is provided with a target (30), an inductance coil (40), a transmission/reception circuit (41), a magnetic circuit unit (10), and a magnetic detection unit (20). The target (30) is fixed to the rotating body. The inductance coil (40) is fixed to the fixed body at a position facing the target in the axial direction. The transmission/reception circuit (41) detects the position of the target by applying an alternating current to the inductance coil. The magnetic circuit part (10) is formed in a cylindrical shape around the axis and is fixed to a rotating body. The magnetic detection unit (20) is fixed to the fixed body and is provided in a region radially inward of the inner peripheral surface (101) of the magnetic circuit unit. An inductive sensor is constituted by a target, an inductance coil, and a transmission/reception circuit, and a magnet-type rotation angle sensor is constituted by a magnetic circuit unit and a magnetic detection unit.
位置检测装置对设置成相对于固定体(2)能够绕着规定的轴心(CL)进行旋转或摆动的旋转体(3)的位置进行检测,具备靶标(30)、电感线圈(40)、收发电路(41)、磁回路部(10)和磁检测部(20)。靶标(30)固定于旋转体。电感线圈(40)在与靶标在轴心方向上对置的位置处固定于固定体。收发电路(41)对电感线圈施加交流电流来检测靶标的位置。磁回路部(10)绕着轴心形成为筒状且固定于旋转体。磁检测部(20)固定于固定体且设置在比磁回路部的内周面(101)靠径向内侧的区域。通过靶标、电感线圈和收发电路来构成电感式传感器,通过磁回路部和磁检测部来构成磁铁型旋转角传感器。
