PROBLEM TO BE SOLVED: To provide a revolving speed adaptive vibration absorber capable of obtaining particularly a long life and sure operability. SOLUTION: In this revolving speed adaptive vibration absorber, a plurality of inertia mass units 19 adjacent in a peripheral direction are respectively supported in two hold parts 21 adjacent in a peripheral direction in a hub part 17, the hold part includes a pin 1, and this pin can be rolled on the inertia mass unit and curve tracks 27, 29 curved mutually in the reverse direction of the hub part, in this way, when a rotational vibration overlapped in a rotary motion is generated, a space of the inertia mass unit from a rotary shaft is contracted along a curved operating track, each pin has an outer shell surrounding a hollow chamber, and the hollow chamber is left as a cavity part or charged with a material of density lower than density of the outer shell.
