ABSTRACT:
An endless belt 1 for transmission is provided with a number of blocks 2, 3 which frictionally engage input and output pulleys, and vibration-absorbing members 6, 7 are interposed between mutually adjacent ones of the blocks 2, 3. The vibration-absorbing members 6, 7 are constituted by a first retainer 6 which clamps one block 2 of the mutually adjacent blocks 2, 3, and a second retainer 7 which clamps the other block 3, these retainers being intervening between the mutually adjacent blocks 2, 3. Accordingly, neighboring blocks 2, 3 are reliably prevented by the vibration-absorbing members 6, 7 from directly colliding with each other, as a result of which noise can be effectively reduced. In addition, vibration produced by the block 2 itself is absorbed by the first retainer 6 constituting the vibration-absorbing member. Likewise, vibration produced by the other block 3 itself is absorbed by the second retainer 7.
