入され固定されている。 FIG. 1 is a perspective view of an automobile door corner piece as an example of a resin molded product for a vehicle, where 1 is a molded product and 2 is an insert nut. Fig. 2 is a plan view showing a conventional insert nut, Fig. 3 is a longitudinal sectional view thereof, Figs. 4 and 5 are perspective views, and Figs. 6 and 7 are longitudinal sectional views showing the installed state. .
The insert nut 2 has a resin layer 5 covering the entire outer peripheral surface of the nut body 3 except for the bolt insertion surface 4, the screw holes 6 are closed, and a gas vent groove 7 is provided on the outer surface of the resin layer 5. ing. A boss 8 is formed on the mounting surface of the molded product 1, a mounting hole 9 is formed in the boss 8, and an insert nut 2 is inserted into the mounting hole 9 and fixed.

車体パネル１０に取付ける。 In the above structure, the insert nut 2 is inserted into the mounting hole 9 formed by the boss 8 of the molded product 1 by applying a solvent or adhesive to the outer peripheral surface of the resin layer 5, as shown in FIG. Fixed by welding or gluing. The gas and internal air generated at this time are exhausted from the gas vent groove 7. Then, as shown in Fig. 7, the bolt insertion surface 4 side is attached to the vehicle body panel 1.
0, and then tighten the bolt 11 from the opposite side.
The molded product 1 is attached to the vehicle body panel 10 by screwing into the screw hole 6.

穴６より短めにしなければならないなどの問題点
があつた。 However, in such a conventional mounting device, since the gas vent groove 7 is formed on the outer peripheral surface, the adhesion force between the resin layer 5 and the boss 8 is reduced, stress is concentrated in the groove part, and it is easy to break. Further, when molding the resin layer 5, the resin infiltrates into the screw holes 6 and fills in the spaces between the screw threads, so there is a problem that the threaded portion 12 of the bolt 11 must be made shorter than the screw hole 6.

あつた。 Furthermore, it has been proposed that an insert nut in which the outer surface of the nut body is covered with a resin layer is attached to a sandwich-like panel in which both sides of a honeycomb core are covered with an outer skin (British Patent No. 1353236).
Since this insert nut is only partially fixed to the partition wall that forms the honeycomb core, stress concentrates on the fixed part and it is easy to break. Since the bolts were not coated, there was a problem in that the strength of the screwed bolts in the axial direction was weak.

The purpose of the present invention is to solve the above-mentioned problems by fixing the resin layer to the entire inner surface of the mounting hole, and by providing an opening on the surface of the resin layer opposite to the bolt insertion surface and using it for gas venting.

is smaller than the outer diameter of the nut body 3 and larger than or the same diameter as the inner diameter, and the resin layer 5 does not cover at least a part of the surface of the nut body 3 opposite to the bolt insertion surface 4. The other configurations are the same as those in FIGS. 1 to 7. The resin forming the resin layer 5 is preferably one that is compatible with the molded article 1, particularly one that can be welded using the same solvent.

Since the resin does not penetrate into the screw hole 6, the screw hole 6 can be effectively used over its entire length, and a bolt 11 having a threaded portion 12 longer than the screw hole 6 can be used. Also, gas vent groove 7
Since the resin layer 5 is fixed to the boss 8 on the entire outer surface thereof, the fixing force is large, and destruction due to stress concentration in the groove is prevented.

られる。 As explained above, according to this idea,
The entire outer peripheral surface of the nut body except for the bolt insertion surface is covered with a resin layer, and the entire outer surface is fixed to the entire inner surface of the mounting hole, and an opening is formed on the surface of this resin layer opposite to the bolt insertion surface. Because of this, there is no need to provide a gas vent groove, which increases the adhesion force between the insert nut and the molded product, prevents destruction of the resin layer, and increases the strength of the bolt in the axial direction. I can do it. Furthermore, since resin can be prevented from entering the screw holes, the screw holes can be used effectively to increase the tightening force, and the bolt lengths do not need to be precisely aligned.
