<p><P>PROBLEM TO BE SOLVED: To provide a rotation fluctuation absorbing pulley which can more efficiently reduce torque fluctuation, and has high reliability without the need for a large designing space. <P>SOLUTION: The rotation fluctuation absorbing pulley includes: a hub 1; a pulley body 2 which is disposed to be relatively rotatable with respect to the hub 1 so that axial relative displacement is regulated; and a coupling unit 3 interposed between the hub 1 and the pulley body 2. The coupling unit 3 includes: a movable mount 31 which is movable to both the hub 1 and the pulley body 2; a biasing means 32 for axially biasing the movable mount 31; a first guide means 33 having a cam-like track 33a having an end which guides the relative movement direction of the movable mount 31 in a direction diagonally crossing the axial direction with respect to one of the hub 1 and the pulley body 2; and a second guide means 34 having an axial path 34a which axially guides the relative movement direction of the movable mount 31 with respect to the other of the hub 1 and the pulley body 2. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
