To enable a weight to vibrate in a well-balanced manner in the front-rear direction without being affected by the deadweight of the weight itself in a seat with a dynamic damper, so that the damping effect can be exerted efficiently.SOLUTION: In a dynamic damper in which a weight 15 is supported, so that it can oscillate at least in the front-rear direction, via elastic members S2 and S3 on frames 12, 10 of a headrest 4 or a seat back 3 of a seat 1, or a cushion member 13 supported by the frames 12, 10, the weight 15 is arranged so as to extend in the vertical direction on the one vertical straight line L when viewed from the side of the seat.SELECTED DRAWING: Figure 2

    【課題】ダイナミックダンパ付きシートにおいて、重錘の自重の影響を受けることなく重錘を前後方向にバランスよく振動させ得るようにして制振効果を効率よく発揮できるようにする。【解決手段】シート1のヘッドレスト4又はシートバック3のフレーム12,10、或いは該フレーム12,10に支持されるクッション部材13に、重錘15が弾性部材S2,S3を介して少なくとも前後方向に振動可能に支持されるダイナミックダンパにおいて、重錘15は、シート側面視で一鉛直線L上を上下方向に延びるように配置される。【選択図】 図2
