<p>PURPOSE: To improve electromagnetic responsiveness, and to simplify constitution by fitting a semi-circularly expanded guide leg part provided with an engagement claw in an oblong fitting hole for engagement. CONSTITUTION: A guide leg part 6a of an armature hub 6 is freely fitted to a plurality of fitting holes 2 which are concentrically cut in a gear 1. A key- shaped elastic member 5 such as a leaf spring is fixed to the inner side of the gear 1, and the tip of the elastic member 5 is engaged with and locked to a recess of the armature hub 6. A clutch body 8 side is assembled by fitting a bearing 10 and a cylindrical body 9 to a yoke where an electromagnet 11 is built in, and when the current flows, an armature 7 is attracted by the electromagnet 11, and the engagement claws are engaged with each other by being slid through the guide of the semi-circular guide leg part 6a and the fitting hole 2 against the elastic force of the elastic member 5 of the gear 1 so as to be brought into press contact with the cylindrical body 9 side. The turning motion of the gear 1 is smoothly transmitted to a connecting member to be connected to a rotary shaft 13.</p> |
