To provide an antivibration device 1 having improved antivibration performance.SOLUTION: An antivibration device 1 includes plate springs 11, 21 connecting a vibration generation source 2 to a vibration transmitted part 3. Elastic deformation parts 11a, 21a are formed in a plate shape having a thickness in a X direction and adapted to be elastically deformed by vibration transmitted from the vibration generation source 2 to vibrate themselves in the X direction. An elastic deformation part 11b is formed in a plate shape having a thickness in a D2 direction and adapted to be elastically deformed by vibration to vibrate itself in the D2 direction. An elastic deformation part 21b is formed in a plate shape having a thickness in a D5 direction and adapted to be elastically deformed by vibration to vibrate itself in the D5 direction. The X direction, the D2 direction, and the D5 direction are set to be different directions from one another. Thus, the antivibration device 1 vibrates itself in three different directions by vibration transmitted from the vibration generation source 2.SELECTED DRAWING: Figure 1 【課題】防振性能を向上するようにした防振装置１を提供する。【解決手段】防振装置１は、振動発生源２と被振動伝達部３とを接続する板バネ１１、２１を備える。弾性変形部１１ａ、２１ａは、Ｘ方向に厚みを成す板状に形成され、振動発生源２から伝わる振動によって弾性変形してＸ方向に振動する。弾性変形部１１ｂは、Ｄ２方向に厚みを成す板状に形成され、振動によって弾性変形してＤ２方向に振動する。弾性変形部２１ｂは、Ｄ５方向に厚みを成す板状に形成され、振動によって弾性変形してＤ５方向に振動する。Ｘ方向、Ｄ２方向、Ｄ５方向は、それぞれ異なる方向に設定されている。したがって、防振装置１は、振動発生源２から伝わる振動によって、それぞれ、異なる３つの方向に振動する。【選択図】図１
