PURPOSE:To provide a rotor for a brushless motor, in which spaces in the circumferential direction of mutual magnets can be reduced without complicating the shapes of a core and the magnets. CONSTITUTION:A shaft 1 is installed, a core 2, in which a plurality of projection sections 5a-5d are formed at regular intervals in the circumferential direction of an outer circumferential surface, is mounted to the shaft 1, and one side faces 7 set up onto the outer circumferential surface of the core 2 among each one pair of the projection sections 5a-5d and directed in the circumferential direction are positioned and abutted against the opposed side faces 6 of the projection sections 5a-5d while a plurality of magnets 3a-3d, in which recessed sections 8 escaping the projecting sections 5a-5d are shaped on the inner circumferential sides of the other side faces, are attached. |
