PROBLEM TO BE SOLVED: To three-dimensionally operate a door for opening-closing, while having sufficient strength to a load from a side surface.SOLUTION: Respective left-right front pillars are curved in an outward swelling shape toward the outside in the lateral direction in response to proceeding to a midway part from both ends in the vertical direction, an upper part more than a lower part is formed in a backward inclined shape positioned in the rear, and a door openably-closably arranged between the respective left-right front pillars and respective left-right rear pillars, is pivoted on the left-right rear pillars via a hinge metal fitting. Respective left-right fenders comprise a vertical surface part joined to an end part of a floor sheet and a top plate part for covering an upper part of a rear wheel with an upper part of this vertical surface part and becoming a forward-downward shape to the front of the rear wheel, and are connected to the lower end of the rear pillars in an upper part of this top plate part. An outside surface of the respective left-right rear pillars is curvedly formed in an outward swelling shape, and the outside surface of the rear pillars and a pivot shaft of the door are arranged so that the lower end side becomes the rear on the outside of the upper end side.
【課題】 側面からの負荷に対して十分な強度を有しながら、ドアを三次元的に開閉動作できるようにする。【解決手段】 左右各前ピラーを上下方向両端から中途部に行くに従って左右方向外側方に向かう外側方膨出状に弯曲するとともに、下部より上部が後方に位置する後方傾斜状に形成しており、左右各前ピラーと左右各後ピラーとの間に開閉自在に配置されるドアを左右後ピラーにヒンジ金具を介して枢支しており、 左右各フェンダは、フロアシートの端部に接合された立面部と、この立面部の上部で後輪の上方を覆いかつ後輪の前方へ前下り状となっている天板部とを有し、この天板部の上部で後ピラーの下端と連結しており、左右各後ピラーの外側面を外側方膨出状に弯曲形成するとともに、後ピラーの外側面及びドアの枢支軸を下端側が上端側より外側方でかつ後方になるように配置する。【選択図】図1
