Further, since the rigidity of the vehicle body is improved, the thickness of the headlight support plate 5 can be reduced, so that the vehicle body 1 can be made lighter. Further, the 'stretching arm 1G' extends in the vertical direction of the vehicle body to join the flange portion (10) to the front end upper rod 6, and at the same time, the flange portion iQd is coupled to the headlight support plate 5 and the mud sealing plate 7 Therefore, a closed section is also formed in the up and down direction of the vehicle body, because & 'by the car body!
