Abstract

PURPOSE:To prevent a bolt from inclining by notching a part corresponding to the bolt-inserting hole of a projection as one part of a recess molded through a metal mold for molding other notch, while the projection in one plane with a bearing surface is left in the center in the width direction of a notch provided in the bearing surface in the mounting bracket of a resin molded product. CONSTITUTION:An inserting hole 23 is formed as the overlapping part of a pair of notches 25, 27 molded in the upper and lower faces of a bracket 21 body. A projection 30 in one plane with a bearing surface 21a is left in the center in the width direction of the notch 25 provided on the side where the bearing surface 21a exists. Then, a recess 32 notches a part corresponding to the inserting hole 23 of the projection 30 so that the inserting hole 23 is formed. Further, the projection 30 exists in the center of the notch 25 on the upper face side so that the head of the bolt mounts on the projection 30. Therefore, a load by tightening is applied equally to the bearing surface so that inclining of the bolt can be prevented effectively and the deformation of the mounting bracket 21, the fracture of the screw thread of the bolt and nut, etc., can be avoided.

2. Description of the Related Art FIG. 10 to FIG.
An example of a conventional mounting bracket of this type similar to that shown in Japanese Patent Publication No. 79 etc. is shown. The mounting bracket 1 has a tongue-shaped bracket body protruding from a base body of a resin molded product, and a bolt insertion hole 3 penetrating in a direction perpendicular to the upper and lower surfaces of the bracket body. Bolt insertion hole 3
Is formed as an overlapping portion of a pair of cutout portions 5 and 7 formed on the upper and lower surfaces of the bracket body, and the cutout portions 5 and 7 are in directions parallel to the upper and lower surfaces of the bracket body and facing each other. That is, it is molded by a pair of molds (so-called two-direction punching molds) that are separated in the directions of arrows A and B. Further, the upper surface of the bracket body is a seat surface for receiving the bolt.

By the way, when the bolt insertion hole 3 is formed by such a two-way punching die, the notch 5 having a width corresponding to the diameter of the bolt insertion hole 3 exists in the seat surface. Therefore, when the bolt is tightened, there is a problem that a part of the head of the bolt 10 falls into the cutout portion 5 and the bolt 10 tilts as shown in FIG. Therefore, although the washer 11 is used to prevent this, the tilt of the bolt 10 still cannot be effectively prevented.
If tightening is performed while the bolt 10 is tilted, the mounting bracket 1 may be deformed or damaged, and in some cases, the threads of the bolt 10 or nut (not shown) may be damaged, so improvement is desired. It was rare.
