    • PROBLEM TO BE SOLVED: To provide a vibration control damper which is capable of suppressing a sectional defect range generated in a joint part by the formation of a long hole, and even when a plasticized part is broken, prevents the tip of the plasticized part beyond the broken position from being completely separated.SOLUTION: The vibration control damper includes: a pair of hysteretic type damper parts 11; an intermediate part 20; and a displacement regulation part. The pair of hysteretic type damper parts 11 are arranged at both ends in the axial direction holding the intermediate part 20 therebetween. Each hysteretic type damper part 11 includes the plasticized part 12 and a stiffening part 19. The plasticized part 12 faces alternate axial force acting in the axial direction. The stiffening part 19 is provided around the plasticized part 12 and restricts the buckling of the plasticized part 12. To the intermediate part 20, one end side of each plasticized part 12 configuring the pair of hysteretic type damper parts 11 is connected, which connects the pair of hysteretic type damper parts 11 each other. The displacement regulation part regulates the expansion amount in the axial direction of the plasticized part relative to the stiffening part. In the vibration control damper 10 of this invention, each of the pair of hysteretic type dampers 11 is provided with the displacement regulation part.
