<P>PROBLEM TO BE SOLVED: To precisely suppress a rotational shift variation amount of a timing belt having an intrinsic rotational shift variation amount, in a synchronized drive unit transmitting power of a drive pulley 103 to a driven pulley 105 via a drive timing belt 101, a relay pulley 104, and a driven timing belt 102. <P>SOLUTION: A drive timing belt 101 and a driven timing belt 102 are constituted as a plurality of narrow timing belts arranged side-by-side in a rotational axis direction of a relay pulley 104. By means of a mark 106 indicating the direction and the place of the drive timing belt 101 and a mark 107 indicating the direction and the place of the driven timing belt 102, the drive timing belt 101 and the driven timing belt 102 are provided with a positional relation in which eccentric components thereof counteract each other on the driven pulley 105 (driven side member). <P>COPYRIGHT: (C)2012,JPO&INPIT |
