A rotor is used in a motor (17) for driving the rotation of an impeller (16) of a fuel pump (10). The rotor is provided with: a tubular bonded magnet (41, 63) configured from a plurality of magnets; an inner core (42, 62) that is a tubular member provided inside the bonded magnet (41, 63), both axial end surfaces (43, 44) of the inner core (42, 62) being outwardly exposed; and a rotor shaft (38) in which the centroid (G) of a transverse cross-section coincides with the axis of rotation (AX) while a pair of flat surfaces (45) are formed parallel to each other, the rotor shaft (38) having a connection terminal (39) that fits into the impeller (16) and is provided so as to pass through the interior of the inner core (42, 62). |
