PROBLEM TO BE SOLVED: To provide a rotational fluctuation absorption pulley which prevents dust from entering into a bearing slide part without depending on a seal lip.SOLUTION: A rotational fluctuation absorption pulley includes: a hub 1 attached to a rotary shaft; a sensing plate 2 attached to the hub 1 and having a detected part 25 for detecting rotation; a pulley body 4 supported by a hub 1 side member through a radial bearing 3; and coupling rubber 5 which connects the pulley body 4 with the hub 1 side member so that the pulley body 4 and the hub 1 side member may be displaced relative to each other in a circumferential direction. An outer periphery part of the sensing plate 2 is bend toward the outer periphery side of the pulley body 4.SELECTED DRAWING: Figure 1 |
