PURPOSE:To perform a cushion start, by providing smoothly protrusive and root parts in a suitable internal from both skirts to the idle pulley side of a V-belt, mounting the V-belt to a boss part of an idle pulley and detachably mounting the V-belt to a driving pulley. CONSTITUTION:A control handle 6 is turned to move an idle pulley 3 to the side of a driving pulley 2, when protrusive parts 15, provided in one side of a V- belt 5, are contacted to the idle pulley 3, the other side of the V-velt 5 is contacted to the driving pulley 2, when root parts, provided in one side of the V- belt 5, are contacted to the idle pulley 3, the V-belt 5 is moved to a side of the idle pulley 3 to a position separated with the other side of the belt from the driving pulley 2. Accordingly, when the idle pulley 3 is placed in said position, if the protrusive part 15, provided in one side of the V-belt 5, is contacted to the idle pulley 3, the V-belt 5 is pressed moving to a side of the driving pulley 2 and contacted to a friction surface of the driving pulley 2, then the pulley 3 can be integrally connected to the driving pulley 2 through the V-belt 5, thus a turning effect can be transmitted to a driven side speed change V-pulley B. |
