To provide a compact centrifugation pendulum vibration absorbing device that can ensure the weight of a mass body while inhibiting collisions between the mass bodies adjacent to each other and abnormal noise generation due to the collisions.
A first mass body 22 and a second mass body 23 of the centrifugation pendulum vibration absorbing device 20 are opposite to each other in the axial direction of a support member 21 via an arm member 24, and are formed with two metal plates 221 connected with each other, or a first metal plate 231 and a second metal plate 232. The two metal plates 221 for constituting the first mass body 22 form a gap G in the end of the first mass body 22 on the side of the second mass body 23, which means both ends thereof. The end 231e of the first metal plate 231 for forming the second mass body 23 on the side of the first mass body 22 is loosely fitted into the gap G corresponding to the first mass body 22 when the first mass body 22 and second mass body 23 move with respect to the support member 21 to come close to each other.
