WIPO Patent Application WO/2016/136498
Kind Code:
A1
Abstract:
A friction drive pulley mechanism is provided with an idler pulley (30) which is located between a drive pulley (10) and a driven pulley (20), is held in contact with the drive pulley (10) and the driven pulley (20) by pressing force applied by a pressing means, and transmits, by means of frictional force caused by the contact, the rotational force of the drive pulley (10) to the driven pulley (20). The friction drive pulley mechanism is further provided with an idler pulley pressing mechanism (40) for pressing the outer-diameter surface of the idler pulley (30) toward the radial center thereof against the pressing force to release the contact of the idler pulley (30) with the drive pulley (10) and/or the driven pulley (20).
