To provide a dynamic damper having a novel structure which can be reduced in a size while effectively securing the durability of support rubber elastic bodies, a spring characteristic or the like.SOLUTION: Mass support bodies 14 arranged at both sides of a mass member 12 which is elongated in a length to left and right directions have structures in which attachment members 18 attached to vibration control objective members 42, and mass fixing members 20 fixed to left and right end parts of the mass members 12 are elastically connected to each other by support rubber elastic bodies 22 in a vertical direction. The support rubber elastic bodies 22 of the left and right mass support bodies 14, 14 are inclined to left and right outer sides from either of the attachment members 18 and the mass fixing members 20 toward the other, and the support rubber elastic bodies 22, 22 of the left and right mass support bodies 14, 14 are inclined to the same directions in fore-and-aft directions from either of the attachment members 18 and the mass fixing members 20 toward the other. Fore-and-aft dimensions of the support rubber elastic bodies 22 are set larger than left and right dimensions of the support rubber elastic bodies 22.SELECTED DRAWING: Figure 1

    【課題】支持ゴム弾性体の耐久性やばね特性などを有効に確保しつつ、小型化を実現することができる、新規な構造のダイナミックダンパを提供すること。【解決手段】左右方向に長尺とされたマス部材12の左右両側にそれぞれ配されたマス支持体14が、制振対象部材42に取り付けられる取付部材18と、マス部材12の左右端部に固定されるマス固定部材20とを、支持ゴム弾性体22によって上下方向で相互に弾性連結した構造を有している。左右のマス支持体14,14の各支持ゴム弾性体22が取付部材18とマス固定部材20の何れか一方から他方に向けて左右外側へ傾斜していると共に、左右のマス支持体14,14の支持ゴム弾性体22,22がそれぞれ取付部材18とマス固定部材20の何れか一方から他方に向けて前後方向で互いに同じ向きに傾斜しており、更に支持ゴム弾性体22の前後方向寸法が支持ゴム弾性体22の左右方向寸法よりも大きくされている。【選択図】図1
