PROBLEM TO BE SOLVED: To provide a joint structure for a shaft, capable of reducing its manufacturing cost while allowing easy control of a boundary between a soft magnetic region and a non-magnetic region.SOLUTION: The joint structure for a shaft 100 includes a soft magnetic material component 10 as part of a shaft component on one end side in the axial direction, and a non-magnetic material component 20 as part of the shaft component on the other end side in the axial direction. One of the soft magnetic material component 10 and the non-magnetic material component 20 has a female screw part, and the other has a male screw part. With the male screw part threaded to the female screw part, screw joint is allowed between the soft magnetic material component 10 and the non-magnetic material component 20. |
