摘要： Yoke plates (3a, 3b) of magnetic material adapted for rotation in synchronism with a rotary shaft (2) are installed. An axially magnetized magnet (5) is disposed through the yoke plates (3a, 3b) and an air gap (G1). The outer diameter (R1) of the yoke plates (3a, 3b) is larger than the outer diameter (R2) of the magnet (5). The magnet (5) is fixed to a fixing plate (6) of magnetic material. Hall ICs (9a, 9b) are attached to the front ends of the pole pieces (8a, 8b) of the fixing plate (6). The Hall ICs (9a, 9b) are disposed in a magnetic circuit (M) formed by the magnet (5). When the rotary shaft (2) rotates, the opposed areas (S1, S2) between the magnet (5) and the yoke plates (3a, 3b) vary, so that the density of magnetic flux passing through the Hall ICs (9a, 9b) in the magnetic circuit (M) linearly varies in proportion to the rotation angle. The Hall ICs (9a, 9b) catch this variation and detect the rotation angle of the rotary shaft (2). Thereby, the cost of production of the rotation angle detection device is reduced without deteriorating the detection accuracy.

摘要： Holder anchoring grooves are arranged on the outer periphery of a rotor core so as to extend axially. A holder arm having a substantially T-shaped cross section is fitted to each of the holder anchoring grooves. The holder arm has a main body section, an engaging projection and magnet holding pieces. The engaging projection is engaged with the corresponding one of the holder anchoring grooves. Each of the magnet holding pieces includes a first contact section, a second contact section and a non-contact area. A magnet containing section is defined by the magnet holding pieces that are located vis-à-vis relative to each other of any two adjacently located holder arms and the outer peripheral surface of the rotor core. In the magnet containing sections, a rotor magnet is press fitted and anchored from the shaft direction. Thus, there is provided a magnet fixing structure that can accurately anchor magnets to a rotor core or the like at low cost.
