Description

[Detailed explanation of the invention] (Industrial application field) This invention is applied to outer panels such as automobile roof panels.
Concerning structures for mounting exterior parts such as roof racks and air spoilers.

(Prior art and its problems) As a structure for attaching a roof rack to a roof panel, as shown in Japanese Utility Model Application No. 56-139640, there is a structure that uses a mounting bracket hooked to a drip channel. As shown in Fig. 2, there is a roof rack in which the legs c of the roof rack are screwed using mounting holes b formed in the roof panel a.

The latter roof rack mounting structure, as shown in FIG. 8, has an elastic protector e interposed between the boss portion d of the leg portion c of the roof rack and the bottom outer edge j and the roof panel a. A screw shaft f protruding downward is passed through the mounting hole b, and the screw shaft f is passed through a hole h of a reinforcement g arranged inside the roof panel a,
By tightening the nut i screwed into the protruding end of the screw shaft f, the leg part c of the roof rack, the protector e, the roof panel a and the reinforcement g are connected, and the roof rack is attached to the roof panel a.
It is to be installed on.

This conventional example has the following problems.

The fastening means consisting of the screw shaft f and the nut i is brought into a tightened state by the elastic compression of the protector e, but since the protector e is made of rubber, the nut i is said to easily loosen due to vibrations of the vehicle body. There's a problem.

Since the portion of the reinforcement a that serves as the seating surface of the nut i needs to be arranged perpendicular to the helical axis f, a gap is generally formed between this portion and the roof panel a. Ru. Therefore, the torque during tightening is applied from the boss d to the peripheral edge of the mounting hole b via the protector e, which may deform the peripheral edge of the mounting hole b, as shown by the imaginary line. In order to avoid this, if the tightening force is weakened, the nut i tends to loosen, making the support of the roof rack c unstable.

In order to avoid the above-mentioned disadvantages, the boss portion d and the screw shaft f may be formed perpendicularly to the roof panel a, but the curvature of the roof panel a differs depending on the vehicle model, which impairs versatility.

Although the above-mentioned problem relates to the roof rack mounting structure, the same problem also occurs when the structure shown in FIG. 8 is used as a mounting structure for other exterior parts such as an air spoiler.
