PROBLEM TO BE SOLVED: To provide an alignment adjustment jig in which a mutual alignment among several pulleys can be identified and adjusted accurately by simple mechanism and operation. SOLUTION: The alignment adjustment jig according to the invention comprises reference shaft 2 projected from the end face of each pulley 55-57 and an engagement jig 3 engageable with each of the reference shaft 2. The engagement jig 3 further comprises reference holes 7 to which the reference shaft 2 of each pulley 55-57 is inserted, a connecting member 5 to fix each of the reference hole 7 at specified location, and an adjustment means 6 which enables an insertion of the reference shaft 2 of a tension pulley 56 into the reference hole 7 in the direction of adjustment between shaft center distance. Alignment of each of the pulley 55-57 is confirmed and adjusted by whether each of the reference hole 7 of the engagement jig 3 fits snugly or not against each of the reference shaft 2.
