<P>PROBLEM TO BE SOLVED: To increase the efficiency of the work for winding a cable body around a driving drum stored in a main body case. <P>SOLUTION: A tip part of a driving shaft 34 supported rotatably in the case 25 by a bearing 33 protrudes into a drum storage chamber 31a, and a male screw part 55 is formed in the tip part of the driving shaft 34. The male screw part 55 is provided with a first male screw part 56 and a second male screw part 57, and a nut for fixing is screw-fitted into the second male screw part 57 while a female screw part 59a of the driving drum 41 and the first male screw part 56 are mutually screw-fitted to fix the driving drum 41 on the driving shaft 34. When winding a closing side cable 24b around a guide groove 41a of the driving drum 41, a part of the driving drum 41 is held at the position where it axially protrudes from outer peripheral walls 50a, 50b of the drum storage chamber 31a by mutual meshing of the first male screw part 56 and the female screw part 59a. <P>COPYRIGHT: (C)2010,JPO&INPIT |
