Kind Code:
A1
Abstract:
The power steering device pertaining to the present invention has a steering angle sensor (3) for detecting a rotation angle of a steering shaft, and a torque sensor (4) for detecting a torque generated in the steering shaft. The steering angle sensor (3) detects a magnetic field generated from a first gear magnet (33) and a second gear magnet (34) through use of a first gear magnetic detection unit (35) and a second gear magnetic detection unit (36) installed on a first mounting surface (81) of a substrate (8). The torque sensor (4) detects a magnetic field generated from a torque sensor magnet (40) through use of a torque detection magnetic detection unit (45) installed on a second mounting surface (82).
