PROBLEM TO BE SOLVED: To solve a problem of elongated cycle time due to need for concentration in assembling work because a side surface part of a pulley need be targeted in setting a carrier belt on the pulley. SOLUTION: This pulley has such structure that it is cylindrical to rotate around a center shaft 10, with the carrier belt 11 set on a side surface part 12 to be driven. Projections 14 are provided in a rotation axial direction on a circular surface 13 that is perpendicular to the shaft 10 in similar diameter to that of the circular surface 13 or larger. When the carrier belt 11 is set on the projection 14 by mistake when trying to set the carrier belt 11 on the side surface part 12, the carrier belt 11 is automatically moved to the side surface part 12 as the pulley is rotated. In setting the carrier belt 11, a target range can be larger, thereby cycle time can be shortened. COPYRIGHT: (C)2005,JPO&NCIPI
