[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator shroud mounting structure, and more particularly to a sub-assembled radiator shroud mounting structure.

[0002]

2. Description of the Related Art Radiators, front grills, bumpers,
Assembling headlamps and other parts into a radiator shroud into one unit, and attaching this unit to the front of the vehicle body of the vehicle, the vehicle body front structure of the vehicle and the assembling method aiming at reducing the number of assembly steps are Kaihei 3-22778
No. 2 publication. According to this structure and the assembling method, the wheel apron 101 at the front of the vehicle body of the automobile 100 is used.
Wheel apron reinforcement 102 above
Are joined. A radiator shroud mounting bracket 103 protruding inward in the vehicle width direction is mounted near the front end portion of the wheel apron reinforcement 102. As shown in FIG. 23, the mounting bracket 103 includes a base portion 103a fixed to the wheel apron reinforcement 102 and a mounting portion 103b extending inward in the vehicle width direction from the base portion. Bolt insertion holes 106 for attaching the fastening portions 104 provided at both ends of the radiator shroud to the attachment portion 103b.
Is formed, and the nut 105 is joined from the back surface corresponding to the bolt insertion hole 106.

When mounting the radiator shroud on the vehicle body, as shown by the arrow in FIG. 24, the radiator shroud is engaged with the mounting bracket 103 from the front of the vehicle body, and the fastening portion 104 is installed above the mounting portion 103b. Next, with the positioning hole 108 on the fastening portion side and the positioning hole 109 on the mounting portion side being further tentatively aligned with the bolt insertion hole 107 of the fastening portion 104 and the bolt insertion hole 106 formed in the mounting portion 103b, Positioning hole 1 from above
08, 109 through the positioning pin 110, the relative positioning of the mounting portion and the fastening portion, the relative positioning of the bolt insertion holes 106, 107, then using the bolt 111, the nut 105 The shroud fastening portion 104 and the mounting bracket 103 are integrated.

[0004]

In such mounting work, if the hole formed in the fastening portion 104 and the hole formed in the mounting portion 103b corresponding to this hole are not completely aligned, the upper portion Positioning pin 110 that came down from
Alternatively, the fastening bolt 111 is used for the hole 1 of the mounting portion 103b.
Around the circumferences of 06 and 109, there is a problem that the mounting portion 103b is pressed downward and the mounting portion 103b is bent downward as shown by a chain line in FIGS. 26 and 27.
