In this case, it is desirable to back-tighten the screws where they are visible, but it is difficult to fasten the screws from the inside of the bezel, so it is difficult to attach the bezel to the car body so that the screws are not visible from the outside. It was wanted.

The present invention was developed in view of the above circumstances, and allows panels, etc. to be connected to each other so that the screws are not visible from the outside, and is therefore suitable for use when attaching a bezel to the body of an automobile. The purpose is to provide a connector for

Means for Solving the Problems In other words, in order to achieve the above object, the present invention provides a connection in which an object to be attached having a protruding attachment boss is connected to a panel having an attachment notch formed at the end edge thereof. The member has a size that can be inserted into the mounting notch, is formed into a headed cylinder shape into which the protruding boss is inserted into the internal hollow part, and has a screw insertion hole in the upper end surface. A drilled screw inserter is provided, and a screw inserter is provided at the front of the screw inserter so that the free end portions of the screw inserter come into contact with both side walls of the notch when the screw inserter is inserted into the notch. A pair of resilient wings protrudes outwardly or rearwardly from the screw inserter, and bases are connected to both sides of the screw inserter, forming panel inserts at these bases. A pair of clip bodies in which elastic clamping pieces are connected in a folded state are provided, and the screw is inserted through the screw insertion hole into the mounting boss of the object to be attached, which is inserted into the hollow part of the screw insertion body, and the screw is screwed into the clip body. Fixing the object to be attached to the screw inserter, inserting the screw inserter into the mounting notch of the panel, and sandwiching the panel between the bases of the panel inserters and the elastic clamping pieces, and The panel is characterized by being configured so that the panel is locked by the elastic restoring force of the free tips of both vanes which are pushed from both side walls of the notch and displaced rearward by inserting the screw insert into the notch. A connecting member is provided.

Function The connecting member of the present invention has the above-described structure, so that the screw inserter is fixed to the object to be attached with the screw, and
After the connecting member is attached to the object to be attached, screw inserts are inserted into the attachment notches of the panels, and the panels are respectively clamped between the bases of both panel insertion sections and the elastic clamping pieces. In addition, at this time, a pair of resilient blade plates that are disposed at the front of the screw inserter and protrude outwardly or rearwardly from the screw inserter are inserted into the notch portion of the screw inserter. When the blades come into contact with the walls on both sides of the notch, the pair of blades are pressed by the walls on both sides of the notch and are displaced backwards.As a result, the elastic restoring force of the free tips of both blades causes the panel to to lock. Therefore, the connecting member of the present invention is secured to the panel by the pair of clips holding the panel and the free tips of the vanes pressing against the side walls of the panel notch. Therefore, by installing the connecting member in advance in such a way that the head of the screw is not visible from the outside when the panel and the object are connected, and then attaching the object to the panel, the screws can be removed. It is possible to connect an object to be attached to a panel without backing the panel with the heads of the screws invisible from the outside. Also, when inserting the screw insert into the notch of the panel, the tips of the pair of vane plates come into contact with the peripheral wall of the notch of the panel, and the vane plates are displaced rearward and attached to the panel with cushioning properties. Since the screw inserter is inserted into the notch easily and with good workability, the blade plate remains displaced backward after insertion, and the elastic return force of the free tips of both blade plates is applied. As a result, each of the vanes presses the walls on both sides of the notch outward, so that the screw inserter can be inserted into the notch without any gaps, and even if the connecting member vibrates while driving a car, the vane will not bend. ,
This vibration is absorbed by the spring force of the slats, which prevents the connecting members from rattling. Furthermore, by providing the slats in this way, the dimensions of the notch in the panel can be adjusted to some extent. Even if there are variations, the slats follow the panel surface, absorbing the variations in dimensions, and preventing wobbling.
