PROBLEM TO BE SOLVED: To provide a rotor capable of preventing a split core from being dropped from a base core, the rotor being configured by assembling the split core around which a coil is wound, with the base core.SOLUTION: In the state where a tab tail 16 is inserted into a groove 2, a split core 4 can be slid a little in a radial direction of a base core 3. Therefore, when the split core 4 is pushed in toward the inside in the radial direction of the base core 3, a state where the tab tail 16 partially protrudes from an inner peripheral surface 8a into a fitting space 8 is provided. When the tab tail 16 is pushed in toward the outside in the radial direction of the base core 3, a state where the tab tail 16 is brought into contact with a side face 2a of the groove 2 is provided. Even if the tab tail 16 is pushed in the direction of an arrow B further from such a state, since the split core 4 cannot be moved in the direction of the arrow B, the split core 4 can be prevented from being dropped from the base core 3.SELECTED DRAWING: Figure 4 |
