<P>PROBLEM TO BE SOLVED: To highly precisely restrict rotation deflection fluctuation quantity of all the timing belts each having specific rotation deflection fluctuation quantity. <P>SOLUTION: Between a drive pulley 125 and a driven pulley 128 fixed to a rotation shaft 127 of a driven object 126 of a cylindrical form, a timing belt 129 for transmitting torque is wound and stretched. The timing belt 129 is a combined constitution of two double-faced toothed thin-width timing belts 129A and 129B obtained by separating a single double-faced toothed belt having teeth on both sides. The double-faced toothed thin-width timing belt 129A is reversed, and the double-faced toothed thin-width timing belt 129B is set as it is to be combined with it, thereby they are used as the timing belt 129. <P>COPYRIGHT: (C)2004,JPO |
