Description of the Related Art Conventionally, this kind of clip is made of a plastic material and has a flange-shaped portion having a boss hole penetrating vertically in the center and a locking portion on the outer periphery, and has a lower surface of the flange-shaped portion. And a plurality of elastic locking pieces each projecting from the cylindrical body and disposed in a cylindrical shape as a whole. A stopper is pushed in and a female member made of a flexible member that holds the part by engaging the locking portion with the edge of the mounting hole on the back side of the vehicle body panel material, and is fitted into the boss of the female member. A male member for holding the elastic locking piece in the engaging direction, and inserting the female member into the mounting hole with the male member inserted halfway through the boss portion, and thereafter the male member is inserted. A member in which a member is fitted to the last position and attached is disclosed in, for example, Japanese Patent Application Laid-Open No. 63-1. It is known in Publication No. 7708. Further, in this clip structure, when the male member pushed to the last position is pulled back to the above-mentioned halfway position, the female member can be removed together with the male member from the vehicle body panel material.

[0003]

However, in the above-described conventional clip structure, the distal end portions of the elastic locking pieces are individually divided and free. In addition, the clip may be removed for maintenance etc., but the time when it is held in use is much longer, so the elastic locking piece has a tendency to open outward due to use, and it seems that it has been removed. In such a case, the free end side of the elastic locking piece remains open outward. For this reason, there is a problem that it is difficult to attach the clip when the clip is attached again, and the workability is poor.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to provide a clip having a structure that can be easily mounted even when repeatedly mounted. Further, other objects will be clarified sequentially in the contents described below.

[0005]

In order to solve the problem] was to achieve the above purpose
The present invention provides a flange-shaped portion having a boss hole extending vertically in the center and a locking surface provided on the outer periphery, each of which protrudes from the lower surface of the flange-shaped portion and has a substantially cylindrical shape as a whole. And a plurality of elastic locking pieces disposed in the panel. The elastic locking pieces are inserted into mounting holes formed on the panel side, and the locking surface is mounted on the back side of the panel with mounting holes. and the female member can be engaged to the edge, the said fitted into the boss hole the resilient locking piece portion of the female member is elastically deformed in the engagement wear direction, and a male member for holding the deformation In the plastic clip provided, the elastic locking pieces have ends that are one with each other.
And the connecting portions are configured such that the tips do not individually expand outwardly, and the connecting portions have protrusions.

The detailed configuration of the female member 10A will now be described with reference to FIGS. 6 and 7. The female member 10A is made of plastic and has a disc-shaped flange 11 and a lower surface of the flange 11. It has a cylindrical part 12 provided in a state of being hung from the side. A boss hole 13 is provided at the center of the flange 11, and the boss hole 13 is formed up to the vicinity of the distal end forming the connecting portion 14 of the cylindrical portion 12. Further, a shallow counterbore 15 is formed around the boss hole 13 on the upper surface side of the flange 11 around the boss hole 13. On the other hand, the collar 1
On the lower surface side of 1, a shallow counterbore 16 is formed around the cylindrical portion 12.

On the other hand, the cylindrical portion 12 is separated along the circumference at substantially equal intervals, and three slits 17 extending vertically in the outer peripheral portion extend vertically from the lower surface of the flange portion 11. It is formed over the distal end of the tubular portion 12, that is, up to the connection portion 14. Then, the elastic locking pieces 18 are respectively formed between the slits 17, whereby a total of three elastic locking pieces 18 are provided on the lower surface side of the flange 11 in the cylindrical portion 12. Is in a state of being Accordingly, each of the three elastic locking pieces 18 thus formed has its upper end fixed to the lower surface of the flange 11 and its lower end connected by the connecting portion 14. ing. Further, a projection 19 is formed on the inner surface of each elastic locking piece 18 at a position approximately midway between the upper and lower sides. The protruding portion 19 is formed in a state protruding inwardly gradually as approaching coupling unit content 14 side. Further, the connecting portion 14 is provided with a through hole 20 communicating with the boss hole 13 at a position corresponding to the protruding portion 19, and a molding pin (not shown) is inserted into the through hole 20 when the female member 10A is molded. As a result, the projection 19 is easily formed.

FIG. 5 is a bottom view of the male member 10B. Therefore, the detailed configuration of the male member 10B will be described further with reference to FIG. 5. The male member 10B is made of plastic and has a substantially disk-shaped flange portion 21 and a flange portion 21.
And a shaft portion 22 protruding downward at a substantially right angle from the lower surface. The flange 21 is formed to have a size that can be received in the counterbore 15 of the flange 11 of the female member 10A.

The shaft portion 22 has an outer diameter smaller than the inner diameter of the boss hole 13 of the female member 10A and a length smaller than the depth of the boss hole 13. The tip (lower end) is sharp, and a locking portion 23 is provided at a position substantially corresponding to the protruding portion 19 of the female member 10A. The locking portion 23 forms a part of the shaft portion 23 in a large-diameter bulging portion, and corresponds to an upper inclined surface of the large-diameter bulging portion. On the other hand, between the locking portion 23 and the flange portion 21, three protrusions 24 extending in the vertical direction are formed on the outer peripheral portion of the shaft portion 22.
The protruding portion 24 is formed so that the shaft portion 22 is formed in the boss hole 1 of the female member 10A.
3, the male member 10B is pressed into contact with the inner surface of the tubular portion 12 so that the male member 10B can be temporarily fixed in the female member 10A. Is formed as a tapered surface 24a in order to facilitate the operation.

The female member 10A and the male member 10B formed as described above are temporarily assembled and handled as shown in FIG. In this temporary assembly, first, the shaft portion 22 is inserted into the boss hole 13 from the flange portion 11 side of the female member 10A.
The shaft 22 of the male member 10B is pushed in until the tip of the male member 10B loosely comes into contact with the protrusion 19 of the elastic locking piece 18. Then
In the boss hole 13, the projection 24 of the shaft 22 is loosely pressed against the inner surface of the tubular portion 12, and the male member 10 </ b> B
It is in the state temporarily fixed within 0A. In this state, the outer diameter of the cylindrical portion 12 of the female member 10A hardly changes. That is, the elastic locking piece 18 does not bulge outward.

Next, a case where the trim board 2 is attached to the inner panel 1 of the automobile using the clip 10 thus temporarily assembled will be described. First, the trim board 2 is arranged on the inner panel 1 so that the mounting holes 3 correspond to the mounting holes 4.

Next, the clip 10 in the temporarily assembled state is attached. In this attachment, the tubular portion 12 of the female member 10A is inserted from the trim board 2 side (see FIG. 2). In this case, since the outer diameter of the cylindrical portion 12 is formed smaller than the inner diameter of the mounting holes 3 and 4, the cylindrical portion 12 smoothly moves until the flange 11 comes into contact with the trim board 2. Inserted.

Next, the male member 10B is pushed in. Then, as the male member 10 </ b> B is pushed in, the protrusion 19 is released outward while the elastic locking piece 18 is bent by the shaft 22. Thereby, as shown in FIG. 1, the outer periphery of the elastic locking piece 18 swells on the rear surface side of the inner panel 1 to become a locking surface, and the female member 10A cannot return in the removal direction and functions as a clip. In this state, the male member 10
The flange 21 of B is closely attached to the upper surface of the flange 11 of the female member 10A in the counterbore portion 15, and the protrusion 19 of the elastic locking piece 18 on the female member 10A side is engaged with the locking portion 23 of the male member 10B. And the male member 10B is prevented from coming off.
