The screw 105 is screwed into the tapping hole 104 through a through hole 108 provided in the panel 107, and the panel 107 is joined and fixed to the panel 101 by tightening the screw 105.

The conventional fixing structure shown in Fig. 10 is a male type that is molded of resin material.
A clip composed of female members 109 and 110 is used. Male member 1
09 is a head 11 that can be locked to the locking rail portion 112 of the panel 111.
3, a shaft portion 115 extending from one surface of the head portion 113 and having an engaging bulging portion 115a at the tip, and a collar-shaped portion 114 formed on the outer periphery of the upper portion of the shaft portion 115 below the head portion 113. I have it. And the male member 1
09 is a head 113 and a collar-shaped part 114, and both ends 1 of the locking rail part 112.
It is attached to panel 111 with 12a and 112b interposed therebetween. On the other hand, the female member 110 is formed in a tubular shape having the through hole 116 at the center, and is inserted into the hole 102 of the panel 101 and locked.
117 and a mounting flange portion 118 that restricts the insertion amount of the body portion 117
And a plurality of slits 119 provided at the lower end of the body 117 to allow elastic deformation. Also, the female member 110
Is formed so that the inner diameter of the lower end side opening of the body portion 117 is thinner than the outer diameter dimension of the bulging portion 115a, and the mounting flange portion 118 abuts the panel 101 and is inserted until further insertion is restricted. It is attached to the panel 101. Then, the shaft 115 of the male member 109 on the side of the panel 111, the engagement bulge 115a, the female member 110
When it is inserted until it protrudes from the lower end side opening, the panel 111 is joined and fixed to the panel 101 by retaining and locking the outer edge of the lower end side opening.

The conventional fixing structure shown in FIG. 11 is a structure in which a clip made up of male and female members 120 and 121 is used, and a shaft portion 122 of the male member 120 is press-fitted and coupled to a body portion 123 of the female member 121. The male member 120 is
A head 126 having upper and lower collar-shaped portions 126a and 126b that are attached by being brought into contact with the upper and lower surfaces of the panel 124 through the holes 125 of the panel 124, and extending from the lower surface of the head 126 and bulging at the tip. The shaft portion 122 having the engagement bulging portion 127, and the collar-shaped portion 126a, 126.
It is attached to the panel 124 in advance by sandwiching the upper and lower surfaces of the panel 124 with b. On the other hand, the female member 121 is formed in a tubular shape having an inner hollow and an opening at the upper end, and a body portion 129 that is inserted and locked in the hole portion 102 of the panel 101, and an attachment that regulates the insertion amount of the body portion 129. With the flange portion 130, the mounting flange portion 130 is a panel
It is inserted into a state where it abuts against 101 and further insertion is restricted, and is attached to panel 101. And panel 124
When the shaft portion 122 of the male member 120 attached to is inserted into the hollow portion of the female member 121 through the upper end opening, the engagement bulging portion 1
27 is press-fitted into the locking portion 131 in the body 129, and the panel 10
It is a structure in which the panel 124 is joined and fixed to 1.

[Problems to be Solved by the Invention] However, in the conventional fixing structure shown in FIG.
Since the tapping hole 104 is not penetrated, sufficient elastic deformation cannot be obtained when the stopper 103 is inserted into and engaged with the hole 102 on the panel side, and a large force is required at the time of insertion.
Further, since the tapping screw 105 is screwed, workability is poor, and if the tapping screw 105 is overtightened, the stopper 103 is likely to crack.

In the conventional fixing structure shown in FIG. 10, since a means for sealing between the male member 109 and the female member 110 is not provided, the female member 11
Water or the like easily enters through the gap formed between the 0-side through hole 116 and the male member 109, and the distance between the panels is also limited.

In the conventional fixing structure of FIG. 11, since the female member 121 is the body portion 129 in the non-penetrating state, it is easy to prevent entry of water or the like, but it is sufficient when inserting and engaging the hole portion 102 of the panel 101. Since elastic deformation cannot be obtained and a large force is required during insertion, workability is poor. In addition, when the engaging portion 127 of the male member 120 is press-fitted into the locking portion 131 of the body portion 129, the engaging portion 127 is scraped so that a sufficient engaging force cannot be obtained, or a large manufacturing error is desired. Since the engaging force of No. 1 cannot be obtained and the allowable range of manufacturing error is narrow, a high level manufacturing technology is required. Further, when the temperature or the like rises and the entire female member 121 is softened, the engaging force is also reduced, and the reliability is poor.

Therefore, the object of the present invention is to eliminate all the drawbacks of the above-mentioned conventional structure, and assume that the panel can be easily attached and the workability is good, and the sealing property can be made more reliable and the degree of freedom in design can be expanded. The purpose is to provide a clip with a structure that allows it.

[Means for Solving the Problems] In order to achieve the above object, the present invention is to fix two panels in a contact surface form by using detachable male / female members. A head portion that can be locked to a locking portion formed on the one panel, a shaft portion that extends from the lower surface of the head portion and that has an engaging bulge portion at the tip, and a lower portion of the head portion. A sealing brim portion formed on an outer periphery of an upper portion of the shaft portion, and the female member is provided in the other panel in a tubular shape having a through hole into which the shaft portion can be inserted as a center. Body that is inserted and locked in the hole, a mounting flange portion that is formed around the upper end of the body portion and restricts the amount of insertion of the body portion, and a body that is formed around the lower end of the body portion. In a clip provided with a slit that allows elastic deformation in the opening portion on the lower end side, the sealing brim portion of the male member is a female member of the female member. The diameter is larger than the upper end side opening diameter of the body portion and smaller than the hole diameter of the hole portion provided in the other panel, and the engaging bulging portion of the male member is inserted from the upper end side opening portion of the body portion, It is provided at the position of the shaft portion that is pressed into the inner edge of the upper end side opening of the body portion and is substantially pushed into the upper end side opening in a state of protruding from the lower end side opening and locked to prevent it from coming off. .

[Operation] According to the above configuration, for example, before the two panels are integrally joined, the head of the male member is locked to the locking portion formed on one of the panels and is attached in advance. On the other hand, the body portion of the female member is inserted into the hole formed in the other panel until it is regulated by the mounting flange portion to be in a mounted state. Since the female member is attached to the hole portion in a cylindrical shape having a through hole at the center of the body portion, the body portion can be easily inserted into the hole portion by the inward bending deformation of the body portion. It The male member and the female member are inserted into the shaft portion of the female member from the upper end side opening portion of the female member, and when the engaging bulging portion projects from the lower end side opening portion, the coupling is completed and the panel members are joined together.
In this case, when the engaging bulging portion passes through the lower end side opening, the lower end side opening portion is easily expanded in diameter through the slit to allow passage, and conversely when pulling out, the diameter is also expanded through the slit. To make it easier to pull out the engaging bulging portion.

In this invention, when the male and female members are joined together, the sealing brim portion provided on the shaft portion of the male member is pressed against the inner edge portion of the upper end opening of the body portion and the upper end side thereof is pressed. Since the upper end side opening of the body of the female member is almost pushed into the opening and is sealed with the strength corresponding to the pressure contact force, the sealing action can be more reliably obtained, and the space between the panels is increased. Even if there is a relative displacement between the female and male members attached to each panel, the shaft of the male member is pressed against the inner edge of the upper opening of the female member. The sealing brim portion can maintain a stable joined state without rattling.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

1 to 8 show a fixing structure to which a clip according to an embodiment of the present invention is applied, which is an example of a structure in which a side garnish of an automobile is attached to a vehicle body side panel.
1 is a bottom view of the clip according to the embodiment shown in a combined state, and FIG. 2 is a side sectional view taken along the line AA of FIG. 1 in a state in which two panels are combined, FIG. 3 is a side view showing a part of the panel before joining the two panels, and FIG. 4 is a side view seen from a direction shifted by about 90 degrees from FIG. 3, 5 is a top view of the male member of the clip, FIG. 6 is a bottom view of the male member of the clip, FIG. 7 is a top view of the female member of the clip, and FIG. It is a horizontal sectional view which follows the BB line.

In the figure, the clip 1 is composed of a male member 2 and a female member 3, both of which are molded of a resin material such as polyacetal. The male member 2 is attached to the side garnish side which is the one panel 4, and the female member 3
Is attached to the vehicle body side panel 5 which is the other panel 5, and the male member 2 and the female member 3 are joined together to integrally join the two panels 4 and 5 together.

More specifically, the male member 2 includes a brim-shaped head 8 that is locked to a locking portion 7 that is formed so as to surround the through hole 6 of the one panel 4, and one side of the head 8. A shaft portion 10 extending in a rod shape and having an engagement bulging portion 9 at the tip is provided, and a sealing brim portion 11 is integrally provided on the outer periphery of the upper portion of the shaft portion 10 below the head portion 8. .

Of these, the engagement bulging portion 9 is formed in a truncated cone shape that is sharpened toward the tip, and the portion connected to the shaft portion 10 is formed as a tapered surface 12.

The sealing flange portion 11 is formed in a dish shape and is elastically deformable. Further, the distance between the engagement bulging portion 9 and the sealing brim-shaped portion 11 is formed to be slightly shorter than the total length of the female member 3 described below, and the engagement bulging portion 9 penetrates and is coupled. When the sealing collar 11 is opened, the upper end side opening of the body of the female member 3 is opened.
The inner edge of 14 is pressed into contact with the upper opening 14 so that it can be pushed into the opening 14. The size of the sealing brim 11 is set to be larger than the inner diameter of the body upper end side opening 14 of the female member 3 and smaller than the hole diameter of the hole 21 provided in the other panel 5.

On the other hand, the female member 3 is formed in a substantially cylindrical shape and has a through hole 13 inside the body portion 17 for allowing the shaft portion of the male member 2 to pass therethrough. Further, a mounting flange portion 15 is provided on the outer peripheral surface of the upper end side opening portion 14 for receiving the male member 2, and the engaging portion 16 (first portion) is provided in the middle of the outer peripheral surface so as to face the mounting flange portion 15.
(See FIGS. 3, 3, 4 and 7).
In addition, the through hole 13 that vertically penetrates the inside of the body portion 17 has an inner diameter dimension of a size that allows the engaging bulging portion 9 of the male member 2 to be inserted without resistance from the upper end side opening portion 14 side to the middle of the length. The inner diameter dimension of the region extending from the middle of the length to the lower end side opening 18 is gradually reduced so that the inner diameter dimension in the vicinity of the lower end side opening 18 becomes smaller than the diameter dimension of the engaging bulging portion 9. It is formed to be thin.

Further, four slits 19 are cut from the lower end side opening 18 on the lower end side of the body portion 17, and the slits 19 allow the body portion to be formed.
The elastic deformation at the lower end side of 17 is facilitated. On the other hand, the torso
The locking portion 16 provided in the middle of the outer peripheral surface of 17 is provided at the free end of the tongue 20. The tongue-shaped piece 20 is formed by cutting in an inverted U shape from a position in the middle of the body portion 17 toward the mounting flange portion 15, and between the mounting flange portion 15 and the free end facing the lower surface, that is, the mounting portion. A space corresponding to the thickness of the other panel 5 is provided between the flange portion 15 and the locking portion 16.

The female member 3 described above is inserted from the lower end side opening 18 into the hole 21 of the panel 5 formed in conformity with the outer diameter of the body portion 17, and the mounting flange portion 15 contacts one surface of the panel 5. It is installed by pushing it in until it is restricted. Further, the locking portion 16 protruding from the outer peripheral surface of the body portion 17 at the time of this pushing is once bent inward by the spring action of the tongue 20 and is restored when passing through the hole portion 21 to restore the hole portion 21. It is attached so that it abuts against the edge and cannot be pulled out.

The male member 2 and the female member 3 configured as described above are connected to the panel 5
The engaging bulging portion 9 of the male member 2 mounted on the panel 4 is made to face the upper end side opening 14 with respect to the female member 3 mounted on, and is further pushed through the through hole 13 to integrally combine. ,panel
The four and five will be superposed and joined. In addition,
In this connection, the engagement bulging portion 9 pushed through the through hole 13 pushes out the inner wall whose inner diameter is narrowed in the middle, and penetrates while expanding the lower end side opening 18 which is easily elastically deformed by the slit 19. . Then, the taper surface 12 is laid on the edge 22 of the lower end side opening portion 18, thereby completing the coupling.

In this state, the lower surface of the brim portion 11 for sealing is pressed against the inner edge of the upper opening 14 of the female member 3 and is almost pushed into the upper opening, and the pressure contact between the male member 2 and the female member 3 The sealing property of is reliably maintained. Further, since only the mounting flange portion 15 of the female member 3 is present in the gap between the panels 4 and 5, the panels 4 and 5 can be made closer to each other. Moreover, for example, even when the female / male members 2 and 3 attached to the panels 4 and 5 are relatively displaced due to the positional displacement between the through hole 6 and the hole portion 21, for example, the male member 2 Since the shaft portion 10 is in pressure contact with the inner edge of the upper opening 14 of the female member 3 via the sealing flange portion 11, a stable connection state without rattling is maintained.

Thus, both male and female members 2,3 that join the two panels 4,5
Prevents the engagement bulging portion 9 of the male member 2 from coming out by the diameter reduction of the lower end side opening 14 and secures the connected state, but on the contrary, pulls out the male member 2 with a force exceeding the thick holding force of the material. Then, the diameter of the lower end side opening 18 is increased by the deformation allowed by the slit 19. Then, the engagement bulging portion 9 is disengaged by the expanded diameter, and the panels 4 and 5 can be released from each other and can be peeled off. Further, when the male member 2 is pulled out, the lower end side opening portion is guided by guiding the tapered surface 12 of the engagement bulging portion 9.
Since the diameter expansion of 18 is assisted, the engagement swelling portion 9 can be relatively smoothly released without being scraped off.

Although the present invention has been described with reference to the above embodiment, it is needless to say that the invention is not limited to the structure of this embodiment, and various design changes may be made without departing from the gist of the present invention. .

[Advantage of Invention] As described above, the clip according to the present invention is
The sealing collar-shaped portion provided on the shaft portion of the male member is pressed against the inner edge of the upper end side opening of the body part and is almost pushed into the upper end side opening part, and the upper end side opening part of the body part of the female member is subjected to the press contact force. Since it is sealed with the strength according to the above, the sealing action will be reliable and the reliability can be improved, and the gap between the panels can be made closer to each other, and the degree of freedom in design, etc. Even if there is some relative positional deviation between the female and male members attached to each panel, the shaft of the male member is in pressure contact with the inner edge of the upper opening of the female member. It is possible to maintain a stable connection state without rattling through the part.
