また、筒状部21の外周面から中心に向かって2か所のホルダ3が設けられている。ホルダ3にはブラシ5が装填され、電動モータ稼働時には、ブラシ5は端子4を介して(図示しない)外部電源と導通している。この2か所のホルダ3は電動モータの回転軸を中心として約90度の角度を成しており、2極モータを構成している。 Further, two holders 3 are provided from the outer peripheral surface of the cylindrical portion 21 toward the center. The holder 3 is loaded with a brush 5, and the brush 5 is electrically connected to an external power source (not shown) via the terminal 4 when the electric motor is in operation. These two holders 3 form an angle of about 90 degrees around the rotating shaft of the electric motor, and constitute a two-pole motor.
蓋部22は筒状部21の一端側を閉塞しており、蓋部22には後ろ側の軸受けとしての貫通孔220が形成されている。 The lid portion 22 closes one end side of the cylindrical portion 21, and a through hole 220 as a rear bearing is formed in the lid portion 22.
