To provide a dynamic damper which can attenuate vibration while suppressing cost increase and mass increase.SOLUTION: This dynamic damper comprises: an orthogonal hexahedral weight (9a); a base part (8a) having a first wall part (8a1), a second wall part (8a2), and a third wall part (8a4) which respectively face a first face (9a1), a second face (9a2) connected to the first face (9a1), and a third face (9a4) connected to the first face (9a1) and the second face (9a2) among six faces of the weight (9a); a first connection part (9b) which elastically connects the first face (9a1) and the first wall part (8a1) to each other; a second connection part (9c) which elastically connects the second face (9a2) and the second wall part (8a2) to each other; and a third connection part (9d) which elastically connects the third face (9a4) and the third wall part (8a4) to each other.SELECTED DRAWING: Figure 2
【課題】コスト増加及び質量増加を抑えながらも振動を減衰出来るダイナミックダンパを提供する。【解決手段】直交六面体の錘(9a)と、錘(9a)の六つの面の内の、第1の面(9a1),第1の面(9a1)に接続する第2の面(9a2),及び第1の面(9a1)と第2の面(9a2)とに接続する第3の面(9a4)それぞれに対向する第1の壁部(8a1),第2の壁部(8a2),及び第3の壁部(8a4)を有するベース部(8a)と、第1の面(9a1)と第1の壁部(8a1)とを弾性的に連結する第1の連結部(9b)と、第2の面(9a2)と第2の壁部(8a2)とを弾性的に連結する第2の連結部(9c)と、第3の面(9a4)と第3の壁部(8a4)とを弾性的に連結する第3の連結部(9d)と、を備えた。【選択図】図2
