A rotor, motor and brushless motor are provided. This rotor () includes a rotor core (), permanent magnets (), and a protrusion () protruding radially outward between permanent magnets (). The permanent magnets () has a parallel orientation in which the easy magnetization direction is parallel to the radial direction in the center of the permanent magnets (). The circumferential side faces () of the permanent magnets () contact the protrusion () in the circumferential direction. Connection surfaces () of the permanent magnets () are connected to the circumferential side face () and to the outer peripheral surface () on the radial outer side. The front end () of the protrusion () in the protrusion direction is arranged between the center () of the circumferential side face () in the protrusion direction and the crossing ridge portion () where the circumferential side face () and the connection surface () cross.
