Therefore, the support rigidity of the plurality of intermediate fixing portions 110 with respect to the load can be increased.
  • the attachment positions of the plurality of intermediate fixing portions 110 to the outer surface 12 a of the side sill 12 are substantially vertical to the plurality of intermediate fixing portions 110. It is located near the wall portion 116. For this reason, the load of the vehicle width direction which acts on each attachment location can fully be supported by the vertical wall part 116 with large support rigidity. Therefore, the support rigidity of the plurality of intermediate fixing portions 110 with respect to the load in the vehicle width direction can be increased.
  • a rear extension 81 extends upward from the rear end of the garnish 60.
  • the rear extension 81 covers the lower portion of the outer surface 73 a of the rear outer panel 73 of the rear pillar 15.
  • the rear pillar 15 forms a part of the edge of the door opening 52.
  • the fixed end portion 71 of the garnish 60 is attached to the vehicle body 11 such that the relative movement in the longitudinal direction is restricted.
  • the rear extension 81 Since the rear extension 81 is located in the vicinity of the fixed end 71, when the garnish 60 is thermally expanded or contracted, the amount of relative movement in the longitudinal direction with respect to the rear outer panel 73 is very small. That is, the rear extension 81 is hardly displaced relative to the door opening 52. Due to the effect of thermal expansion, the rear extension 81 does not affect the door opening 52 in terms of dimensions. Sufficient dimensional accuracy between the door opening 52 and the door 22 can be ensured. Although the lower part of the outer surface 73a of the rear outer panel 73 is covered by the rear extension 81, the accuracy of the construction (opening / closing condition) of the door 22 with respect to the door opening 52 can be sufficiently secured.
  • the exterior component 60 is not limited to the side sill garnish, and may be configured as a door garnish that is attached to the outer surface of the front door 21 or the rear door 22, for example.
  • the exterior component 60 may be configured such that one of the rear end portion 71 and the front end portion 91 in the longitudinal direction is a fixed end portion, and the other of the rear end portion and the front end portion is a movable end portion.
  • the vehicle exterior member mounting structure of the present invention is suitable for mounting the side sill garnish 60 to the side sill 12.

Abstract

L'invention porte sur une structure de montage pour un composant extérieur de véhicule pour monter un composant extérieur en résine (60) sur une caisse de véhicule métallique (11). Le composant extérieur est construit avec un matériau long qui a une conductivité au moins sur une surface de celui-ci et qui est long dans la direction avant-arrière de la caisse de véhicule. Soit l'extrémité arrière (71) soit l'extrémité avant (91) du composant extérieur dans la direction de la longueur est une extrémité fixe qui est attachée à la caisse du véhicule avec un boulon métallique (75), de telle sorte que des mouvements relatifs de l'extrémité fixe sont restreints. L'autre extrémité, à savoir l'autre soit de l'extrémité arrière soit de l'extrémité avant du composant extérieur dans la direction de la longueur, est une extrémité mobile qui est attachée à la caisse de véhicule de telle manière que l'extrémité mobile est autorisée à se déplacer par rapport à la caisse de véhicule dans la direction de la longueur en fonction de la dilatation thermique du composant extérieur. Le boulon est fixé à la caisse du véhicule tout en étant maintenu en contact avec une surface de l'extrémité fixe.
