PROBLEM TO BE SOLVED: To provide a vibration reduction unit which has a piezoelectric elastic member such as piezoelectric rubber, is arranged between a support body such as a vehicle body frame of a vehicle and a supported body such as a cab, can reduce vibration transmitted from the support body to the supported body, and in particular, is low in cost and saved in space, a vibration reduction support device, and a vibration reduction method.SOLUTION: Power generation piezoelectric rubber 21 which generates electricity when deformed by being applied with an external force, and a driving piezoelectric elastic member 22 which is deformed when carried with electricity are laminated on each other, and electrodes 21b, 21b of the power generation piezoelectric elastic member 21 and electrodes 22b, 22b of the driving piezoelectric elastic member 22 are electrically connected to each other so that the deformation of the driving piezoelectric elastic member 22 becomes deformation in a direction in which the deformation of the power generation piezoelectric elastic member 21 is offset when carrying electricity which is generated by the power generation piezoelectric elastic member 21 to the driving piezoelectric elastic member 22.

    【課題】圧電ゴム等の圧電性弾性部材を有して、車両の車体フレーム等の支持体とキャブ等の被支持体の間に配設されて、支持体から被支持体に伝達される振動を低減することができ、特に、低コストかつ省スペースである振動低減ユニット、振動低減支持装置及び振動低減方法を提供する。【解決手段】外部の力が加わって変形すると電気を発生する発電用の圧電性ゴム21と、電気が通電されると変形をする駆動用の圧電性弾性部材22とを積層すると共に、発電用の圧電性弾性部材21で発電した電気を駆動用の圧電性弾性部材22に通電した時に、駆動用の圧電性弾性部材22の変形が発電用の圧電性弾性部材21の変形を相殺する方向の変形となるように、発電用の圧電性弾性部材21の電極21b、21bと駆動用の圧電性弾性部材22の電極22b、22bとを電気的に接続して構成する。【選択図】図1
