PURPOSE:To enable to transmit high load without enlarging a space by winding a separate belt body to make an endless circle on pulleys inside a V-belt between a drive pulley and a driven pulley. CONSTITUTION:A V-belt 12 is wound between a drive pulley 1A and a driven pulley 1B, and inside this V-belt 12, another endless circle belt body 13 is wound between pulley 1A and 1B in the same plane with the V-belt 12. In this way, though severals belts are wound between the drive pulley 1A and the driven pulley 1B, the space required for wrapping can be equalized with that for the winding of a single belt. This construction permits to obtain a high load transmission equivalent to the winding of several belts even in a narrow space. |
