Abstract

A motor includes a metal base plate and a resin holder extending upward from the base plate. The base plate includes a flat plate portion, a through hole passing through the flat plate portion, and a plurality of claw portions extending upward from an edge of the flat plate portion which includes the through hole. A portion of the holder is in the through hole. The holder covers a portion of each claw portion. The holder is thus engaged with each claw portion to prevent the holder from turning around a rotation axis and from coming off in an upward direction. The holder includes a gate mark near a lower surface of the flat plate portion and at a circumferential position between adjacent ones of the claw portions to make it easier for the resin to fill a cavity inside molds during a molding process.
