PROBLEM TO BE SOLVED: To provide a centrifugal pendulum type vibration control device which has an improved vibration control performance and simplified structure.SOLUTION: A centrifugal pendulum type vibration control device 1 comprises a support 2 rotatable around a central axis line O by an output from a driving source; a plurality of inertial bodies 3 spaced in the rotating direction of the support 2; and supporting means 4 movably supporting the inertial bodies 3 in a direction perpendicular to the axis line O in respect to the support 2. Caps 5 having cavity parts 51 storing each of the opposing end portions 31 of each of the inertial bodies 3 are arranged between the adjoining inertial bodies 3. The supporting means 4 supports the inertial bodies 3 as a variation of output from the driving source is increased in such a way that they may be moved to the axis line O in a radial direction of a circle with the axis line O as a center. The cap 5 forms a clearance between the bottom surface of the cavity part 51 and an end surface of the end portion 31 facing against the bottom surface when no variation of output from the driving source occurs. As the variation of output from the driving source is increased, a total sum of clearances decreases. |
