PROBLEM TO BE SOLVED: To provide an angle detector used in a device for detecting torque to be generated in a vehicle steering shaft, and having a smaller dimension in a direction of extention of the steering shaft.SOLUTION: An angle detector includes a magnet 11 having a fist insertion hole, a yoke 12 having a second insertion hole, a magnetism collection plate 13 for capturing a magnetic flux, and a magnetic detection element 14 for detecting the magnetic flux. An angle detector can be inserted into the first and second insertion holes to detect a rotation angle of an object. A magnet is magnetized in an insertion direction of the object, and has a magnetic pole surface where N-poles and S-poles are alternately arranged at equal intervals in a direction of turning the outer periphery of the object. The yoke includes a first yoke facing one magnetic pole surface and having a first magnetic pole claw, and a second yoke facing the other magnetic pole surface and having a second magnetic pole claw. When the first magnetic pole claw approaches one magnetic pole of the magnetic pole surface, the second magnetic pole claw approaches the other magnetic pole. |
