<p>PROBLEM TO BE SOLVED: To suppress a relaxation phenomenon in the part becoming an outer peripheral side by making a distance of a contact range of a V groove pulley to an inner wall part of a V groove in the radial direction of the V groove pulley a half or above of a whole thickness in the direction. SOLUTION: In this belt for the pulley, the distance of the contact range of the V groove pulley to the inner wall part 102 of the V groove in the radial direction of the V groove pulley is made a half or above of the whole thickness in the direction shown by the arrow A. Then, the belt for the pulley is bent in circular arc along peripheral surfaces of respective pulleys 101, 104. However, in the belt for the pulley, since the distance of the contact range to the inner wall part 102 of the V groove in the radial direction of the V groove pulley is made a half or above of the whole thickness in the direction, the matter that an expansion amount of a planar surface part 1 becomes remarkably larger than the expansion amount of the inner peripheral side part abutted on respective pulleys 101, 104 is eliminated, and the relaxation phenomenon in the planar surface part 1 hardly occurs.</p> |
