A bumper is provided with to-be-engaged projections, a radiator grille is provided with engaging projections. The radiator grille is allowed to move and approach bumper rearward of a vehicle. According to this configuration, the engaging projections engage the to-be-engaged projections and they are engaged with and fixed to each other. At this time, a bumper-side seizing unit of the bumper is fitted into a grille-side seizing unit of the radiator grille, thereby limiting the vertical direction. In an engaged state between the engaging projections and the to-be-engaged projections, an inclining surface of one of the engaging projections comes into contact with a rearward inclining surface of the one of the to-be-engaged projections, and an inclining surface of the other engaging projection is separated from a rearward inclining surface of the other to-be-engaged projection.
