PROBLEM TO BE SOLVED: To provide a centrifugal pendulum vibration absorbing device capable of suppressing generation of abnormal noise associated with changes in rotation of a support member mounted on a rotating element.SOLUTION: A support member 11 of a centrifugal pendulum vibration absorbing device 10 includes a plurality of guide openings 12a, 12b formed therein. Each guide opening includes, as a single opening: a first opening area 121 having a guide surface 121a for guiding a mass body 18 to swing along a predetermined track via a guide roller 181 while supporting the guide roller 181 that is radially outwardly urged by centrifugal force; a second opening area 122 having two stopper surfaces 122a, 122b for regulating a swinging range of the mass body 18 by abutment with a stopper roller 182; and a third opening area 123 having a self-weight support surface 123a for supporting a self-weight support roller 183 when the mass body 18 moves by the own weight associated with changes in the rotation of the support member 11. |
