<P>PROBLEM TO BE SOLVED: To efficiently conduct assembling operation by enabling the tentative assembling of a clutch mechanism and an output drum. <P>SOLUTION: The clutch mechanism 12 includes a field core 15 fixed to a base member 7 with a solenoid coil 14 assembled in it, a rotor 16 rotatably and externally fit to a shaft 10 for supporting the output drum 11 and connected to a speed reduction mechanism 9 through the center of the field core 15, an armature 17 externally fit to a shaft 10 in a manner of being rotatable and movable in a shaft direction so that a friction surface 171 faces the friction surface 164 of the rotor 16, capable of transmitting the rotation of the rotor 16 to the output drum 11 so as to be magnetically attracted by the friction surface of the rotor 16 when electricity is applied to the solenoid coil 14 and a first engaging means 27 for preventing the dislocation of the rotor 16 from the shaft 10 and a second engaging means 29 for preventing the dislocation of the field core 15 from the rotor 16 in an operation step before connecting the rotor 16 to the speed reduction mechanism 9. <P>COPYRIGHT: (C)2008,JPO&INPIT |
