To solve a problem that in a stopper structure for elastically supporting a back door 2 of a vehicle at a closing position, when loss of elasticity occurs in an elastic member on a conventional stopper reception part side due to aging deterioration, since in some cases, shortage of an interference amount of a stopper reception part with respect to a stopper on the back door side causes a gap between both of the parts and the gap causes looseness and noise generation during traveling, it is required to secure a sufficient interference amount even if aging deterioration occurs.SOLUTION: A lip part 24 of a stopper reception part 20 includes: a bent part 25 serving as a starting point of elastic deformation; and an abutment reception part 23 on which an abutment part 11b of a stopper 11 abuts. The abutment reception part 23 has a first abutment angle part 26 on a tip side and a second abutment angle part 27 on a base part side, on which the stopper 11 abuts step by step. Through sequential abutment of the first abutment angle part 26 and the second abutment angle part 27 step by step, the interference amount is secured.SELECTED DRAWING: Figure 5

    【課題】車両のバックドア2を閉じ位置に弾性的に支持するストッパ構造において、従来ストッパ受け部側の弾性部材が経年劣化によりヘタリが発生すると、バックドア側のストッパに対するストッパ受け部の干渉量が不足して、両者間に隙間が発生する場合がある。隙間は、走行中のガタツキや異音発生の原因となる。経年劣化によっても十分な干渉量が確保されるようにする必要がある。【解決手段】ストッパ受け部20のリップ部24は、弾性変位の起点となる屈曲部25と、ストッパ11の当接部11bが当接される当接受け部23を有する。当接受け部23に、ストッパ11が段階的に当接される先端側の第1当接角部26と基部側の第2当接角部27を有する。第1当接角部26と第2当接角部27を順次段階的に当接させて干渉量を確保する。【選択図】図5
