VEHICLE SEAT SUPPORT PART STRUCTURE

PROBLEM TO BE SOLVED: To provide a vehicle seat support part structure which enables further improvement of seat vibration absorption performance.SOLUTION: A vibration absorber is disposed between a movable rail side member and a seat body side member. The vibration absorber includes: an inner cylinder 24 which is attached to a first member that is one of the movable rail side member and the seat body side member with its axial end surface butted with the first member; and a rubber elastic member 25 in which an outer periphery part is attached to a second member that is the other member of the movable rail side member and the seat body side member and an inner periphery part is fixed to the inner cylinder 24. At least one axial end part of the rubber elastic member 25 faces the first member through axial gaps d1, 2d which enable the rubber elastic member 25 to contact with the first member.SELECTED DRAWING: Figure 3 【課題】シートの振動吸収性能をより高めることができる車両のシート支持部構造を提供する。【解決手段】可動レール側部材とシート本体側部材の間に振動吸収体を介装する。振動吸収体は、可動レール側部材とシート本体側部材のいずれか一方の部材である第１の部材に軸方向の端面を突き当てて取り付けられる内筒２４と、外周部が、可動レール側部材とシート本体側部材のいずれか他方の部材である第２の部材に取り付けられるとともに、内周部が内筒２４に固定されるゴム状弾性部材２５と、を備える。ゴム状弾性部材２５の軸方向の少なくとも一方の端部は、第１の部材に対して、当接可能な軸方向の隙間ｄ１，ｄ２をもって対峙させる。【選択図】図３
