Furthermore, a locking portion 25 is formed on the inner surface of the leg body 22 at a position corresponding to the fitting portion 23 and is formed of a tapered slope 25a and a second engaging portion 25b.

Further, the filamentous bodies 30 are connected to the outer lower end of the fixed seat 14 and the head 21, respectively. Further, the fixed seat 14 and the tilting seat 15 have a sixth
As clearly shown in FIG.
Engagement step portions 14a and 15a, which are respectively engaged by the screws 3, are cut out in the center of the inner surface.

Therefore, the member connecting fastener 10 with the above structure
The operating procedure for connecting the second object to be connected, ferret molding B, to the first object to be connected, fender A, will be explained using the sectional view shown in FIG. 7 when the connection operation is completed. As shown, the fender molding B is provided with a required number of mounting holes B1 as in the conventional example, but the fender A does not need to be provided with any holes.

As the first operating means, first, a
From the state shown in FIG. 1, the felt molding B is brought into contact with the back surface 12b of the base plate part 12b of the main body 11, and the attachment hole B1 and the insertion opening 16a are aligned, and in this state, holding the fixed part 20, bend the thread-like body 30. , insert the leg portions 22 of the fixed portion 20 in the inverted state into both holes B1 and 16a.

This insertion operation causes the prismatic leg 22 to enter the engagement opening 16, but at this time, the tip of the leg 22 is pushed into the engagement step 15a of the tilting seat 15 while being pressed. , the tilting seat 15 bends from its hinge portion 17 and tilts outward, and when the abutment surface 21a of the head 21 abuts the lower surface of the felt molding B and the approach is stopped, the engagement step portion 15a The fitting part 23 of the leg body 22 is locked in a non-removal state,
Even in this state, the tilting seat 15 maintains its tilted state, so the fixed tongue piece 1 extending from the seat 15
8 comes into contact with the surface 12a of the substrate portion 12 in a pressed state.

At this time, the locking portion 25 of the leg body 22
However, the engagement step portion 1 of the fixed seat 14 maintains an immovable state.

A second connecting body such as a fender molding B is placed between the rear surface 12b of the board part 12, and a fender is placed between the fixing tongue piece 18 extending from the tilting seat 15 tilted by the above fitting and the surface of the base plate part 12. Since the first connected bodies such as A can be attached to each other freely, there is no need to use a locking screw when connecting the two connected bodies, and therefore problems caused by rust can be eliminated and a screw turning tool can be used. Since it is only necessary to fit the fixing body 20 to the main body 11, the number of man-hours and difficulty of the work can be reduced, and the workability can be greatly improved.

Furthermore, according to the present invention, since it is only necessary to drill a connecting hole in the second connected body, it is only necessary to align two holes, and it is not necessary to align multiple holes as in the conventional method. It is possible to eliminate the problem of rust by eliminating holes such as Fender A, without expending labor and time, and because the whole can be integrally molded with synthetic resin material, it is possible to satisfy mass production, and it is also easy to use. There is no rust, and the tilting seat 15 is tilted by fitting the fixed body 20, and the fixed tongue piece 18 strongly presses one of the connected bodies, and the tilting seat 15 is fitted to the fixed body 20 and pressed against it. Therefore, the fitted state becomes highly reliable, and the fixed state of the first connected body clamped by the fixed body 20 also becomes strong.
