<P>PROBLEM TO BE SOLVED: To thin (miniaturize) a driving unit. <P>SOLUTION: A supporting shaft 36 and an output shaft 47 parallel with each other are rotatably supported in a case 26 of the driving unit 22 and connected in a power transmissible manner by a spur gear 48 on one axial end side. A worm gear mechanism 32 and an electromagnetic clutch 41 are arranged on the other axial end side of the supporting shaft 36, and a driving drum 55 is arranged on the other axial end side of the output shaft 47 to reduce and transmit rotational drive of an electric motor 27 to the driving drum 55 through the worm gear mechanism 32, the electromagnetic clutch 41 and the spur gear 48. <P>COPYRIGHT: (C)2010,JPO&INPIT |
