Reference numeral 41 also bulges obliquely forward and downward along the top and bottom of the boss portion 23 to reinforce the boss portion 23 on the rear surface side of the instrument panel 1 corresponding to the rear peripheral edge of the defroster grill mounting opening 11. With respect to the reinforcing rib 41, the tip end surface of the reinforcing rib 41 comes into contact with the mounting surface of the mounting flange 37 to effectively increase the mounting strength of the mounting flange 37 to the boss portion 23.

Here, a procedure for attaching the defroster grill 3 to the defroster grill attachment opening 11 of the instrument panel 1 will be described.

First, as shown in FIG. 2, each mounting flange 37 is attached to the defroster grill mounting opening 11 by a thin hinge 39 so that interference between each mounting flange 37 and the defroster grill mounting opening 11 can be avoided. In the state of being bent inward, the instrument panel 1 is inserted into the defroster grille mounting opening 11 from above. Then, the overlapping flange 33 is overlapped with the recess 13 at the periphery of the defroster grill mounting opening 11 from above to cover the gap between the defroster grill 3 and the defroster grill mounting opening 11. Thereafter, as shown in FIG. 1, each of the mounting flanges 37 is opened to the outside of the defroster grill mounting opening 11 by the thin hinge 39, and the tip end of each of the mounting flanges 37 opened to the outside is removed. The mounting flanges 37 are aligned with the boss portions 23 that bulge from the rear surface side of the instrument panel 1, and the mounting flanges 37 are attached to the boss portions 23 by the screw members 35 that are inserted through the openings 37a of the mounting flanges 37. The defroster grill 3 is screwed and fixed in the defroster grill mounting opening 11. After that, the downstream end opening 21a of the defroster duct 21 is joined to the upstream end opening 3a of the main body 31 of the defroster grill 3 while being overlapped from the outside.

According to the mounting structure of the defroster grill 3 as described above, it is not necessary to form the defroster grill mounting opening 11 large so that each mounting flange 37 does not interfere with the defroster grill mounting opening 11, and the overlapping flange 33 is formed. It is possible to reduce the size of the vehicle, and it is possible to avoid as much as possible that the shadow of the small overlapping flange 33 is reflected on the lower end portion of the windshield to obstruct the driver's visual field. The overlapping flange 33 of the defrost grill 3 which is a member different from that of FIG. 5 is small in size so that the appearance is good, and both the driver's visual field and the appearance of the instrument panel 1 can be improved. Moreover, when the defroster grill 3 is inserted, each mounting flange 37 is bent inwardly of the defroster grille mounting opening 11 by the thin hinge 39, so that the main body portion 31 of the defroster grille 3 is inserted into the defroster grille mounting opening 11. There is no need to make any effort when doing so, and the defroster grill 3 can be easily inserted into the defroster grille mounting opening 11 vertically downward from above with each mounting flange 37 bent inward of the defroster grille mounting opening 11. Can be inserted into.

Further, as described above, a separate flange is not required when attaching the defroster grill 3 to each boss portion 23 on the lower surface of the instrument panel 1, and the defroster grill 3 can be bent by a thin hinge 39 when the defroster grill 3 is inserted. Since it can be attached to each boss portion 23 of the instrument panel 1 with the screw members 35 and 35 with each integral mounting flange 37, separate flanges are made to correspond to the boss portion of the instrument panel and the defroster grill, respectively. Compared to the one that is fastened in a fixed state and tightened by using a screw member, etc., the number of work steps is reduced and the number of parts is reduced by not requiring a separate flange. Also, the number of parts can be reduced.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but includes various other modified examples. For example, in the above embodiment, the mounting flanges 37 are provided so as to project from the lower end of the front wall 31a and the lower end of the rear wall 31b of the body portion 31 of the defroster grill 3 corresponding to the respective boss portions 23, but the respective mounting flanges are located at six locations. It is not limited to this, but may be provided at a location corresponding to the boss portion that bulges from the lower surface of the instrument panel.

Further, in the above-mentioned embodiment, the concave portion 13 is provided at the periphery of the defroster grill mounting opening 11, but the concave portion may not be particularly provided, and the superposed flange of the defroster grill is formed in the defroster grill mounting opening 11. It may be directly polymerized from above with respect to the peripheral edge.
