PROBLEM TO BE SOLVED: To provide a magnet holder of low manufacturing cost capable of attaching a magnet firmly to a shaft while saving the space.SOLUTION: A magnet holder 100 includes a magnet 80 having a through hole 81, and a bush 90 in contact with the lower part of the magnet 80. The magnet 80 has a plurality of recesses 85 formed to separate each other from the inner peripheral surface of the through hole 81 to the outside in the circumferential direction of the recess. A bush 90 has a plurality of claws 95 projecting upward so as to be fitted in the recess 85. At the tip of the claw 95, a protrusion 97 projecting outward and fitting in the recess 85, and a contact portion 98 protruding inward are provided. The magnet holder 100 is attached to a shaft 2 so that the shaft 2 abuts against the contact portions 98 of the plurality of claws 95, respectively, in a state where the bush 90 is attached to the magnet 80, so that the protrusion 97 is fitted to the recess 85.SELECTED DRAWING: Figure 3 |
