Description

  The present invention relates to an attachment structure using a clip for detachably attaching an attachment member to a member to be attached. Specifically, for example, the present invention relates to a mounting structure using a clip for detachably mounting a center cluster or the like on an instrument panel of an automobile.

As a conventional technique, for example, a clip disclosed in Japanese Patent Laid-Open No. 2000-249117 (Patent Document 1) is known as a clip for detachably mounting a center cluster or the like on an instrument panel of an automobile.
The clip disclosed in Patent Document 1 is formed by forming a resin-made clip body attached to a seat member disposed in a projecting state on a center cluster as an attachment member on an instrument panel as an attached member. It is a clip used for locking the mounting member to the mounted member by inserting it from the surface side of the mounting hole and detachably mounting the mounting member to the mounted member.

FIG. 26 shows a partial cross-sectional view of a state in which the attachment member is attached to the attached member using substantially the same clip as that disclosed in Patent Document 1. The resin clip main body 40 engages the engagement protrusion 43 formed at the tip of the seat surface engagement portion piece 42 with the engagement hole 54 of the seat surface member 52 formed in the attachment member 50. Is attached to the attachment member 50. In addition, the resin clip main body 40 engaged with the attachment member 50 is inserted into the attachment hole 62 formed in the attachment target member 60 from the surface side 64 and formed on the attachment locking piece 46 of the clip main body 40. The attachment member 50 is attached to the attachment member 60 by the engagement shoulder 47 engaging the back surface side 66 of the attachment member 60.
When it is necessary to remove the mounting member 50 from the mounted member 60, the mounting locking piece 46 of the clip body 40 is elastically deformed inward by pulling the mounting member 50 strongly, so that the locking shoulder 47 is covered. The attachment member 50 is detached from the back surface side 66 of the attachment member 60, and the attachment member 50 can be detached from the attachment member 60 together with the clip body 40.
The clip main body 40 is attached to the attachment member 50 by engaging the engagement protrusion 43 at the tip of the seat surface engagement portion piece 42 with the engagement hole 54 formed in the attachment member 50. If the surface engaging portion 42 is elastically deformed and the engaging protrusion 43 is disengaged from the engaging hole 54, it is possible to leave only the attaching member 50 from the attached member 60 while leaving the clip body 40 in the attached member 60. .
JP 2000-249117 A

With the clip main body 40 shown in FIG. 26, the attachment member 50 can be attached to the attached member 60 with a predetermined holding load. However, when it becomes necessary to change the holding load, the clip body 40 cannot be used as it is, and the angle or area of the engagement surface 44 of the engagement protrusion 43 of the clip body 40 is changed or attached. A different clip body having a different holding load from the clip body 40 is required by changing the width and angle of the locking shoulder 47 of the locking piece 46 or changing the material of the clip body 40. there were.
Therefore, in order to support mounting with different holding loads, it is necessary to prepare multiple types of clip bodies with different shapes and materials. did not become.

  The present invention is proposed as a solution to the above-described problem, and the problem to be solved by the present invention is to change the thickness of the seat member and to change the shape without changing the shape or material of the clip body. By changing or the like, when the attachment member is attached to the attached member using the same type of clip body, it is possible to cope with different holding loads.

In order to solve the above problems, the clip mounting structure according to the present invention takes the following means.
First, the two-member assembly structure according to the first aspect of the present invention is a clip structure in which a resin clip body is attached to a seat member disposed in a projecting manner on an attachment member attached to a member to be attached.

The leg piece of the clip main body and the seat member are formed so as to contact each other when removing the attachment member from the attached member .

According to the second aspect of the present invention, when the clip structure using the seat member attached in the first direction is removed from the attached member, the clip structure using the seat member attached in the second direction When the body is removed from the attached member, a difference occurs in the contact state of the leg pieces of the clip body with the seat member. That is, in the former, when the clip structure is removed from the attached member, the leg piece of the clip main body and the seat surface member do not come into contact with each other, so that the drag generated in the clip main body can be reduced (the holding load can be reduced). it can). On the other hand, in the latter, since the leg piece of the clip main body and the seat surface member come into contact with each other when the clip structure is removed from the mounted member, the drag generated in the clip main body can be increased (the holding load can be increased). ). Therefore, it is possible to cope with different holding loads when the attachment member is attached to the attached member using the same type of clip body.

According to each invention of the present invention, the following effects can be obtained.
First, according to the first invention described above, when the clip structure using the first seat member is removed from the attached member, the clip structure using the second seat member is removed from the attached member. When extracting, a difference arises in the contact state of the leg piece of the clip body to the seat member. That is, in the former, when the clip structure is removed from the attached member, the leg piece of the clip main body and the seat surface member do not come into contact with each other, so that the drag generated in the clip main body can be reduced (the holding load can be reduced). it can). On the other hand, in the latter, since the leg piece of the clip main body and the seat surface member come into contact with each other when the clip structure is removed from the mounted member, the drag generated in the clip main body can be increased (the holding load can be increased). ). Therefore, it is possible to cope with different holding loads when the attachment member is attached to the attached member using the same type of clip body.

Next, according to the second aspect described above, when the clip structure using the seat member attached in the first direction is removed from the attached member, the seat member attached in the second orientation is removed.

Is held in a narrow pressure state.
The pair of attachment locking pieces 14 are formed with leg pieces 18 extending rearward in the insertion direction, and the rear end of the leg piece 18 in the insertion direction is rearward of the rear end in the insertion direction of the seating surface engaging portion piece 12. It is formed in a configuration that becomes a position. The pair of attachment locking pieces 14 are formed in a wider state than the opening width of the attachment hole 32 in the free state. For this reason, the attachment to the attachment hole 32 is attached in a state where it is elastically deformed relatively inward, and in the attached state, it is in a fitted state as a state in which a resilient force in the expanding direction is applied.
The first seat member 27 has a thickness that prevents the leg pieces 18 of the attachment locking pieces 14 from coming into contact with the first seat member 27. In this embodiment, the thickness at the rear position corresponding to the leg piece 18 is the same as the thickness at the tip end position inserted into the seating surface engaging piece 12.

FIG. 2 shows a clip mounting structure according to the first embodiment of the present invention, in which a resin clip main body 10 is mounted on a second seat member 28 provided in a protruding state on a mounting member (not shown). 6 is a partial cross-sectional view showing a state in which the clip structure 11 is attached to the attached member 30. FIG.
The clip body 10 is inserted into the mounting hole 32 of the mounted member 30 from the surface side 34 in an integrated state with the second seat member 28, and the clip structure 11 is mounted on the mounted member 30.
The clip main body 10 is the same as that shown in FIG. 1, and the clip main body 10 is formed on the inner side, and the pair of seat surface engaging portion pieces 12 sandwiching the second seat surface member 28 is used. And a pair of attachment members formed on the outer side, each having a locking shoulder 16 that locks to the back surface side 36 of the attachment hole 32 of the attached member 30 and having an elastic force in the expanding direction. And a stop piece 14.
Engaging protrusions 13 are provided at the tips of the pair of seating surface engaging part pieces 12, and the engaging protrusions 13 are engaged with engaging holes 24 formed in the second seating surface member 28. The seating surface engaging piece 12 and the second seating surface member 28 are integrated with respect to the acting force in the relative pulling direction. The thickness of the portion of the second seat member 28 that is sandwiched between the seat engaging portions 12 is the same as that of the first seat member 27.
The pair of attachment locking pieces 14 are formed with leg pieces 18 extending rearward in the insertion direction, and the rear end of the leg piece 18 in the insertion direction is rearward of the rear end in the insertion direction of the seating surface engaging portion piece 12. It is formed in a configuration that becomes a position.
A rib 26 is formed at the rear position in the insertion direction of the second seat member 28, and the leg piece 18 of the attachment locking piece 14 abuts on the rib 26 formed on the second seat member 28. ing.
In addition, about the 1st seat surface member 27 and the 2nd seat surface member 28, it can also be set as the following structure.
The first seating surface member 27 may have a thickness such that the leg piece 18 of the attachment locking piece 14 contacts the first seating surface member 27. In this case, the second seating surface member 28 is more than when the leg piece 18 of the mounting locking piece 14 abuts the first seating surface member 27 against the rib 26 formed on the second seating surface member 28. The thickness should be such that the contact is stronger.
Further, the thickness of the rear position corresponding to the leg piece 18 of the first seat surface member 27 may be made thicker than the thickness of the tip portion position inserted into the seat surface engaging portion piece 12. However, it is assumed that the thickness of the rear position corresponding to the leg piece 18 of the second seat member 28 is thinner.

  3 is an external perspective view of the first seat member 27 and the second seat member 28 according to the mounting structure of the first embodiment of the present invention. 3A is an external perspective view of the first seat member 27, and FIG. 3B is an external perspective view of the second seat member 28. FIG. The shapes of the first seat member 27 and the second seat member 28 are the same except for the ribs 26. The guide groove 25 is a guide groove through which the seat surface engaging piece 12 is passed when the clip body 10 is attached to the first seat surface member 27 or the second seat surface member 28.

FIG. 4 shows an insertion structure of the first embodiment of the present invention, in which the clip structure 11 in which the resin clip body 10 is attached to the first seat member 27 is inserted into the attachment hole 32 of the attachment member 30. It is a fragmentary sectional view showing the state just before ending.
In the attachment of the clip structure 11 to the attached member 30 using the first seat member 27, the leg piece 18 is the first seat member until just before the clip structure 11 is inserted into the attachment hole 32. 27 does not abut. The insertion load in this case corresponds to a force required to bend the pair of mounting locking pieces 14 with the locking piece base 15 as a fulcrum so that the locking shoulder 16 can pass through the mounting hole 32. Note that the leg piece 18 abuts against the first seat member 27 immediately before the end of insertion, so that the insertion load is slightly increased from the above, but the effect is slight.
FIG. 5 shows the mounting structure according to the first embodiment of the present invention. The insertion of the clip structure 11 in which the resin clip main body 10 is attached to the second seat member 28 into the mounting hole is completed. It is a fragmentary sectional view showing the state just before performing.
In attaching the clip structure 11 to the attached member 30 using the second seat member 28, the leg piece 18 is the second seat member from the initial stage of insertion of the clip structure 11 into the attachment hole 32. It abuts on the ribs 26 formed on 28. The insertion load in this case is that the pair of mounting locking pieces 14 are bent in the opposite directions at the position where the locking shoulder 16 contacts the mounting hole 32 and the position where the leg piece 18 contacts the rib 26, and the locking shoulder 16 is mounted. This corresponds to the force required to compress and shrink to a width that can pass through the hole 32.
The pair of mounting locking pieces 14 are bent more than the force required to deflect the locking shoulders 16 through the mounting holes 32 by bending the pair of mounting locking pieces 14 with the locking piece base 15 as a fulcrum. The force required to bend in the opposite direction between the position where the locking shoulder 16 abuts against the mounting hole 32 and the position where the leg piece 18 abuts against the rib 26 so that the locking shoulder 16 can pass through the mounting hole 32 is compressed. Therefore, the mounting load using the second seat member 28 is larger than the mounting load using the first seat member 27.

FIG. 6 shows how the clip structure 11 in which the resin clip body 10 is attached to the first seat member 27 from the attachment hole 32 of the attachment member 30 in the attachment structure according to the first embodiment of the present invention. It is a fragmentary sectional view showing the state just before ending.
FIG. 7 shows how the clip structure 11 in which the resin clip body 10 is attached to the second seat member 28 from the attachment hole 32 of the attachment member 30 in the attachment structure according to the first embodiment of the present invention. It is a fragmentary sectional view showing the state just before ending.
When the attachment member is attached to the attached member 30 using the first seat member 27, the leg piece 18 of the clip body 10 is not in contact with the first seat member 27. Accordingly, the holding load of the mounting member on the mounted member 30 corresponds to a force required to bend the pair of mounting locking pieces 14 with the locking piece base 15 as a fulcrum and remove the locking shoulder 16 from the mounting hole 32. To do. In this embodiment, as shown in FIG. 6, the tip end of the leg piece 18 abuts on the first mounting member 27 immediately before the clip structure 11 is detached from the mounted member 30. Therefore, the actual holding load is slightly increased from the force required to bend the mounting locking piece 14 with the locking piece base 15 as a fulcrum and remove the locking shoulder 16 from the mounting hole 32.
On the other hand, when the attachment member is attached to the attached member 30 using the second seat member 28, the leg piece 18 of the clip body 10 is in contact with the second seat member 28. Therefore, the holding load of the mounting member to the mounted member 30 is such that the pair of mounting locking pieces 14, the positions where the locking shoulder 16 locks the mounted member 30 on the back surface side 36 of the mounted member 30, and the leg pieces. This is equivalent to the force required to bend the locking shoulder 16 from the mounting hole 32 by bending it in the reverse direction at the point where 18 contacts the second seat member 28.
Compared to the case where the pair of mounting locking pieces 14 is bent with the locking piece shoulder 15 as a fulcrum and the locking shoulder 16 is removed from the mounting hole 32, the pair of mounting locking pieces 14 are attached to the locking shoulder 16. In order to remove the locking shoulder 16 from the mounting hole 32 by bending in the opposite direction at the position where the back surface side 36 of the member 30 is locked to the mounted member 30 and the position where the leg piece 18 contacts the second seating surface member 28. Need more power.
Therefore, the holding load becomes larger when the second seat member 28 is used as the seat member 22 than when the first seat member 27 is used as the seat member 22. By selecting this, the holding load of the mounting member on the mounted member 30 can be varied.
The clip main body 10 and the first seating surface member 27 or the second seating surface member 28 have an engaging protrusion 13 formed at the tip of the seating surface engaging portion piece 12 of the clip main body 10 as the first seat. The engaging member 24 is engaged with the engaging hole 24 formed in the surface member 27 or the second seating surface member 28, and both are integrated in the pulling direction with respect to the acting force in the relative pulling direction therebetween. The holding load for the attachment member of the main body 10 is set to be larger than the holding load for the attachment member 30 of the clip main body 10. Therefore, the clip body 10 is not detached from the attachment member before the clip body 10 is detached from the attached member 30.

FIG. 8 is a diagram comparing the thicknesses of the first seat member 27 and the second seat member 28 in the mounting structure according to the first embodiment of the present invention.
FIG. 9 shows a result of comparative measurement of holding load when the first seat member 27 is used and when the second seat member 28 is used in the mounting structure according to the first embodiment of the present invention. FIG. As shown in FIG. 9, by changing the plate thickness of the seat member 22, the holding load when the attachment member is attached to the attachment member 30 using the same clip body 10 can be changed. In this example, by providing ribs on the seat member to increase the thickness, the holding load could be 2.3 times compared to the case where no ribs were provided. On the other hand, the insertion load was 1.7 times that of the case where no rib was provided.
The insertion resistance of the clip body 10 is affected by the angle θ1 formed by the inclined surface in the insertion direction of the locking shoulder 16 shown in FIG. On the other hand, the removal resistance is affected by the angle θ2 formed by the inclined surface on the rear side in the insertion direction of the locking shoulder 16 and the side surface of the mounting hole 32 shown in FIG. Here, the smaller the angle, the smaller the resistance. In the clip body 10, θ1 is set to be smaller than θ2, and the insertion load is suppressed to be lower than the holding load.

  The first embodiment of the present invention has been described above, but the present invention can be implemented in various other forms within the scope of the idea of the present invention. For example, in the first embodiment, the rib of the second seat member is provided to increase the thickness of the portion of the seat member that contacts the leg piece, but the seat member itself can be increased in thickness. Further, in the first embodiment, the range in which the thickness of the seat member is increased is the entire range below it including the position where the leg piece abuts, but the range in which the thickness is increased is limited to the portion where the leg piece abuts. You can also.

FIG. 10 shows a clip body 10a used in a modified embodiment of the first embodiment of the present invention. Compared with the clip body 10 used in the above embodiment, the locking shoulder 16 formed outwardly projecting on the mounting locking piece 12 has a straight portion 17.
In the mounting structure using the clip body 10a, since the straight portion 17 is provided on the locking shoulder 16, the stroke that takes the maximum load is increased during the extraction, and the stroke is removed as compared with the mounting structure using the clip body 10 without the straight portion. Therefore, it is necessary to apply the maximum load for a longer time. Therefore, there is a feature that it is difficult to come off against an impact load.
The point that the clip main body 10a can be used for the first seating surface member 27 and the second seating surface member 28 to correspond to different holding loads is the same as when the clip main body 10 is used. Further, since the clip body 10a is common to the clip body 10 except that the locking shoulder 16 has a straight portion 17, detailed description thereof is omitted.
It should be noted that the clip body 10a requires a longer maximum load to be removed, and the feature that the clip body 10a is less likely to come off against an impact load is independent of being able to handle different holding loads. ing.
Therefore, the use of the clip main body 10a is not limited to the present invention, and can be widely used by taking advantage of the feature that the clip main body 10a is not easily detached from an impact load.

In the clip main body 10a, the width between the pair of clamping surfaces 19 of the seating surface joint piece 12 that clamps the seating surface member 22 from the side surface gradually increases from the rear of the clip main body 10a in the insertion direction to the front of the insertion direction. There is a feature that is.
Then, in relation to the seat surface member 22, the width a between the pair of sandwiching surfaces 19 at the rear of the clip body 10 a in the insertion direction is the thickness of the seat surface member 22 sandwiched by the pair of seat surface engaging pieces 12. It is set smaller than b. Further, the width c between the pair of clamping surfaces 19 in the insertion direction front of the clip body 10a is set to be larger than the thickness b of the seating surface member 22 sandwiched between the pair of seating surface engaging pieces 12. That is, in FIG. 10, a <b <c.
Therefore, in a state where the clip main body 10a is attached to the seat surface member 22, the width between the sandwiching surfaces 19 of the pair of seat surface system joining pieces 12 is rearward in the insertion direction of the clip main body 10a. Expands to elastic thickness by elastic deformation. Therefore, since the seating surface member 22 is clamped by the both clamping surfaces 19 of the pair of seating surface engaging portion pieces 12 in a state where the elastic force is applied, the attachment of the clip body 10a to the seating surface member 22 is stabilized. .

Next, a second embodiment of the present invention will be described.
FIG. 11 is an external perspective view of the resin clip body 110 used in the second embodiment of the present invention in a free state.

A guide groove 138 that guides the seating surface engaging piece 114 when the clip body 110 is attached to the first seating surface member 133 is formed at the distal end of the first seating surface member 133.
Following the guide groove 138, an engagement hole 136 for engaging the engagement protrusion 116 of the seat surface engagement portion piece 114 of the clip body 110 is formed slightly above the center of the first seat surface member 133. ing. An escape hole 140 for allowing the leg piece 128 of the clip main body 110 to escape is formed in the center in the width direction of the first seating surface member 133 below the engagement hole 136. The second seating surface member 134 shown in FIG. 13 has the same configuration as the first seating surface member 133 except that the escape hole 140 is not formed.

FIG. 14 shows a state in which the clip structure 112A in which the resin clip body 110 is attached to the first seat member 133 disposed in a projecting manner on the attachment member 130 in the second embodiment is attached to the attachment member 150. FIG.
The clip body 110 is attached to the distal end portion of the first seating surface member 133 with the first seating surface member 133 sandwiched between the pair of seating surface engaging portion pieces 114. It should be noted that the pair of seating surface engaging portions 114 are set to be narrower than the thickness of the first seating surface member 133 to be sandwiched in the free state, and inward in the state of sandwiching the first seating surface member 133. The elasticity is given.
Then, the engaging protrusion 116 formed at the tip of the seating surface engaging part piece 114 is engaged with the engaging hole 136 formed in the first seating surface member 133, and the seating surface engaging part piece 114 and the first Both of the seating surface members 133 are integrated in the drawing direction with respect to the acting force in the relative drawing direction.
The attachment member 130 is attached to the attachment member 150 by inserting the clip structure 112 </ b> A into the attachment hole 152 from the front surface side 154 to the back surface side 156 of the attachment member 150.
The attachment locking piece 120 is formed in a wider state than the opening width of the attachment hole 152 in the free state. Therefore, the attachment to the attachment hole 152 is attached as a state in which the attachment locking piece 120 is elastically deformed inward, and in the attachment state, the attachment locking piece 120 is fitted with a resilient force in the expanding direction. Is in a state.

  FIG. 15 shows a state in which the clip structure 112B in which the resin clip body 110 is attached to the second seat member 134 disposed in a protruding state on the attachment member 130 in the second embodiment is attached to the attachment member 150. FIG. The difference between the clip structure 112 </ b> B and the clip structure 112 </ b> A is that the escape hole 140 is not formed in the second seating surface member 134. The clip body 110 is the same as that attached to the first seat member 133.

Here, the insertion load when the first seat member 133 is used and when the second seat member 134 is used will be described.
When the clip structure 112 </ b> A is inserted into the attached member 150, the protrusion 129 at the tip of the leg piece 128 of the clip main body 110 enters the escape hole 140 of the first seating surface member 133 and is thus released. The deformation is small, and the drag generated on the mounting locking piece 120 is small.
The insertion load in this case is such that the clip structure 112A is pressed against the mounting hole 152 and the pair of mounting locking pieces 120 are bent with the locking piece base 122 as a fulcrum, so that the locking shoulder 125 can pass through the mounting hole 152. It is roughly equivalent to the force required to compress. At the end of the insertion, the leg piece 128 abuts on the first seat member 133 at the base of the leg leg 127 on the side of the projection 129 and is slightly deformed, but the effect is small.

  On the other hand, when the clip structure 112B is inserted into the attached member 150, the second seating surface member 134 does not have the escape hole 140, and the protrusion 129 at the tip of the leg piece 128 of the clip body 110 is inserted during the insertion. It abuts on the second seat member 134. Therefore, since it is necessary to insert the leg piece 128 while deforming it, the drag force generated in the attachment locking piece 120 becomes larger than when the first seating surface member 133 is used. In this case, the insertion load is such that the clip structure 112B is pressed against the mounting hole 152, the pair of mounting locking pieces 120 are where the locking shoulder 125 abuts the mounting hole 152, and the leg piece 128 is the second seating surface member. This is equivalent to the force required to bend in the opposite direction at the place where it abuts against 134 and to be compressed so that the locking shoulder 125 can pass through the mounting hole 152. Therefore, the insertion load becomes larger when the second seat member 134 is used.

Next, the removal load when the first seat member 133 is used and when the second seat member 134 is used will be described.
FIG. 16 is a partial cross-sectional view showing a state in the middle of removing the clip structure 112A using the first seat member 133 from the attached member 150 in the second embodiment.
When the clip structure 112A is removed from the attached member 150, the attachment locking piece 120 is bent with the locking piece base 122 as a fulcrum so that the inclined surface 124 and the straight surface 126 are close to each other as the extraction proceeds. The leg pieces 128 of the locking pieces 120 are close to each other, and the leg pieces 128 come into contact with the first seat member 133. However, since the protrusion 129 formed at the tip of the leg piece 128 is released by the escape hole 140 of the first seating surface member 133, the leg piece 128 comes into contact with the first seating surface member 133 to be attached and locked. The drag generated by the piece 120 is smaller than when the escape hole 140 is not formed.
In this case, the removal load is such that the clip structure 112A is pulled away from the mounting hole 152, the pair of mounting locking pieces 120 are bent using the locking piece base 122 as a fulcrum, and the locking shoulder 125 becomes the mounting hole 152. It is almost equivalent to the force required to compress the width to pass through. At the end of the extraction, the leg piece 128 abuts on the first seat member 133 at the base of the leg leg 127 on the side of the protrusion 129 and slightly deforms, but the effect is small.

FIG. 17 is a partial cross-sectional view showing a state in the middle of removing the clip structure 112B using the second seat member 134 from the attached member 150 in the second embodiment.
When the second seating surface member 134 is used as the seating surface member 132, the mounting locking piece 120 is bent with the locking piece base portion 122 serving as a fulcrum so that the inclined surface 124 and the straight surface 126 approach each other as the removal proceeds. When the leg pieces 128 of the mounting locking pieces 120 are close to each other and the protrusions 129 at the tips of the leg pieces 128 are in contact with the second seating surface member 134, and the first seating surface member 133 is used. The contact state of the clip body 10 with the seat member 134 is different.
Therefore, the deformation of the leg piece 128 is larger than when the protrusion 129 at the tip of the leg piece 128 is released by the escape hole 140 of the first seating surface member 133, and the attachment locking piece 120 is generated by the deformation of the leg piece 128. The drag is greater than when the protrusions 129 of the leg pieces 128 are released by the escape holes 140. In this case, the removal load is such that the clip structure 112B is pulled away from the mounting hole 152, and the pair of mounting locking pieces 120 are brought into contact with the mounting holes 152 and the protrusions 129 of the leg pieces 128. Corresponds to a force required to bend in the opposite direction at a position where it abuts against the second seat member 134 so that the locking shoulder 125 can be pushed and shrunk to a width that can pass through the mounting hole 152.

Therefore, when the clip structures 112 </ b> A and 112 </ b> B are removed from the attached member 150, the first seating surface member 133 and the second seating surface member 133 are different in the contact state of the leg piece 128 of the clip body 110 with the seating surface member 132. By using the seat member 134, it is possible to vary the drag generated when the mounting member 130 is removed from the mounted member 150 using the same clip body 110, and the mounting state of the mounting member 130 with respect to the mounted member 150 The holding load can be made different.
In addition, you may implement in the aspect which forms the 1st seat surface member 133 and the 2nd seat surface member 134 in the same attachment member 130, and there exists only a 1st seat surface member in a certain attachment member. It is also possible to implement in a mode in which only the second seat member is formed on another mounting member.

In the second embodiment, the protruding portion 129 is formed at the center in the depth direction inside the tip of the leg piece 128. However, the protruding portion 129 is divided into two portions in the depth direction at the tip of the leg piece 128. The first seating surface member 133 may be provided with two relief holes 140 corresponding to the depth direction.
In the second embodiment, a protrusion 129 is formed in the center in the depth direction inside the tip of the leg piece 128, and a relief hole 140 having a width into which the protrusion 129 enters is provided in the first seat surface member 133. The protrusion 129 is not essential. Without providing the protrusions 129, it is also possible to make the inside of the tip end of the leg piece 128 thick in the depth direction of the leg piece 128 and provide the escape hole 140 with a width that allows the whole leg piece 128 to enter. The escape hole 140 is not limited to the through hole, and the escape hole 140 may be provided as a recess on both surfaces of the first seat member 133.
In the second embodiment, the thickness of the position where the leg piece 128 of the clip main body 110 abuts on the second seating surface member 134 is the same as the thickness at the position where the seating surface engaging portion 114 engages. The thickness at the position where the piece 128 abuts may be greater than the thickness at the position where the seat surface engaging portion piece 114 engages, and a protrusion may be provided on the second seat surface member 134 side at this position. good.

Finally, a third embodiment of the present invention will be described.
FIG. 18 is an external perspective view of a resin clip body 110A used in the third embodiment of the present invention in a free state. The basic structure of the clip body 110A is the same as that of the clip body 110 used in the second embodiment. Therefore, a detailed description is omitted, and the difference from the clip body 110 will be described.
The difference between the clip body 110 </ b> A and the clip body 110 is in the position and shape of the protrusion 129 formed at the tip of the leg piece 128. In the clip body 110 </ b> A, the protrusion 129 is formed at a position closer to one side in the depth direction of the clip body 110 </ b> A with a slightly narrower width than the clip body 110.

FIG. 19 is an external perspective view of the seat member 132A used in the third embodiment. The seat member 132A is provided on the attachment member 130 in a projecting state and is formed integrally with the attachment member 130, and reinforcement members 135 are provided on both sides for reinforcement. A guide groove 138 for guiding the seat surface engaging piece 114 when the clip body 110A is attached to the seat surface member 132A is formed at the tip of the seat surface member 132A.
Following the guide groove 138, an engagement hole 136 for engaging the engagement protrusion 116 of the seat surface engagement portion piece 114 of the clip body 110A is formed slightly above the center of the seat surface member 132A. An escape hole 140 is formed so as to allow the projection 129 of the leg piece 128 of the clip body 110A to escape toward one side in the width direction of the seat surface member 132A below the engagement hole 136.
In the third embodiment, by changing the direction of attaching 110A to the seat member 132A, the corresponding state of the relief holes 140 of the protrusions 129 and 132A of 110A is changed, so that the seat member 132A has the first seat surface. The role of both the member 133 and the second seat member 134 can be provided.

20 shows a state in which the seat surface member 132A has the role of the first seat surface member 133 in the third embodiment, and the clip structure 112C in which the clip body 110A is attached to the seat surface member 132A is attached to the attached member 150. FIG. In the clip structure 112C, the protrusions 129 of the leg pieces 128 of the clip main body 110A and the relief holes 140 of the seating surface member 132A have corresponding orientations. In FIG. 20, the protrusion 129 and the relief hole 140 of the leg piece 128 are on the front side of the cross section.
FIG. 21 shows a state in which the seat member 132A has the role of the second seat member 134 in the third embodiment, and the clip structure 112D in which the clip body 110A is attached to the seat member 132A is attached to the attached member 150. FIG. In the clip structure 112D, the protrusions 129 of the leg pieces 128 of the clip main body 110A and the escape holes 140 of the seating surface member 132A are not aligned. In FIG. 21, the protrusion 129 of the leg piece 128 is on the front side of the cross section, and the relief hole 140 is on the rear side of the cross section.
22A is a cross-sectional view of the clip structure 112C at the position AA in FIG. 20, and FIG. 22B is a cross-sectional view of the clip structure 112D at the position BB in FIG.

In the clip structures 112C and 112D, the clip main body 110A is attached to the distal end portion of the seating surface member 132A with the seating surface member 132A sandwiched between the pair of seating surface engaging portion pieces 114. It should be noted that the pair of seating surface engaging pieces 114 are spaced at a distance narrower than the thickness of the seating surface member 132A to be sandwiched in the free state, and an inward resilient force is imparted in the state of sandwiching the seating surface member 132A. It has become a state.
Then, the engaging protrusion 116 formed at the tip of the seating surface engaging piece 114 is engaged with the engaging hole 136 formed in the seating surface member 132A, and the seating surface engaging piece 114 and the seating surface member 132A are engaged. Both are integrated in the drawing direction with respect to the acting force in the relative drawing direction.
The attachment member 130 is attached to the attachment member 150 by inserting the clip structure 112 </ b> C or 112 </ b> D into the attachment hole 152 from the surface side 154 of the attachment member 150.
The attachment locking piece 120 is formed to be wider than the opening width of the attachment hole 152 in the free state. Therefore, the attachment to the attachment hole 152 is attached as a state in which the attachment locking piece 120 is elastically deformed inward, and in the attachment state, the attachment locking piece 120 is fitted with a resilient force in the expanding direction. Is in a state.

Here, the insertion load when the seat member 132A is used as the first seat member 133 and the second seat member 134 will be described.
As shown in FIG. 22A, in the clip structure 112C, the protrusions 129 of the leg pieces 128 of the clip body 110A correspond to the escape holes 140 of the seat member 132A. Therefore, when the clip structure 112C is inserted into the attached member 150, the protrusion 129 of the clip main body 110A is released by the escape hole 140 of the seat surface member 132A, so that the leg piece 128 is hardly deformed, and the attachment locking piece 120 is inserted. The drag generated in is small.
On the other hand, as shown in FIG. 22B, in the clip structure 112D, the protrusion 129 of the leg piece 128 of the clip main body 110A does not correspond to the escape hole 140 of the seating surface member 132A. Therefore, when the clip structure 112D is inserted into the attached member 150, the protruding portion 129 of the clip main body 110A is not released by the escape hole 140 of the seating surface member 132A. Therefore, it is necessary to insert the leg piece 128 while deforming it, and the drag generated in the attachment locking piece 120 becomes larger than that in the case of 112C. Therefore, the insertion load is larger in the clip structure 112D than in the clip structure 112C.

Next, the removal load when the seat member 132A is used as the first seat member 133 and when the seat member 132A is used as the second seat member 134 will be described.
FIG. 23 is a partial sectional view showing a state in the middle of removing the clip structure 112 </ b> C in which the seat member 132 </ b> A has the role of the first seat member 133 from the attached member 150 in the third embodiment. .
FIG. 24 is a partial cross-sectional view showing a state in the middle of removing the clip structure 112D in which the role of the second seating surface member 134 is given to the seating surface member 132A from the mounted member 150 in the third embodiment. .
25A is a cross-sectional view of the clip structure 112C at the CC position in FIG. 23, and FIG. 25B is a cross-sectional view of the clip structure 112D at the DD position in FIG.

  When the seating member 132A is used as the first seating member 133, the mounting locking piece 120 is bent so that the inclined surface 124 and the straight surface 126 come close to each other with the locking piece base 122 as a fulcrum as the removal proceeds. Thus, the leg pieces 128 of the attachment locking pieces 120 are close to each other, and the leg pieces 128 come into contact with the first seating surface member 133. However, as shown in FIG. 25 (A), the protrusion 129 formed at the tip of the leg piece 128 is released by the escape hole 140 of the first seat surface member 133, so that the leg piece 128 becomes the first seat surface. The drag generated in the attachment locking piece 120 by abutting against the member 133 is smaller than when the leg piece 128 is not released by the escape hole 140. In this case, the removal load is pulled in the direction in which the clip structure 112C is removed from the mounting hole 152, and the pair of mounting locking pieces 120 are bent with the locking piece base 122 as a fulcrum, so that the locking shoulder 125 becomes the mounting hole 152. It is almost equivalent to the force required to compress the width to pass through. At the end of the extraction, the leg piece 128 abuts on the first seat member 133 at the base of the leg leg 127 on the side of the protrusion 129 and slightly deforms, but the effect is small.

  On the other hand, when the seating surface member 132A is used as the second seating surface member 134, when the removal proceeds, the mounting locking piece 120 uses the locking piece base 122 as a fulcrum so that the inclined surface 124 and the straight surface 126 come close to each other. The leg pieces 128 of the mounting locking pieces 120 are close to each other. Then, the protruding portion 129 of the leg piece 128 comes into contact with a portion where the escape hole 140 of the second seating surface member 134 is not formed, and the clip main body 10 is compared with the case where the first seating surface member 133 is used. There is a difference in the state of contact with the seating surface member 134. Then, the deformation of the leg piece 128 is larger than the case where the protrusion 129 formed at the tip of the leg piece 128 is released by the escape hole 140 of the first seating surface member 133, and the attachment locking is achieved by the deformation of the leg piece 128. The drag force generated on the piece 120 is greater than when the protrusion 129 of the leg piece 128 is released by the escape hole 140. In this case, the removal load is such that the clip structure 112D is pulled in the direction to remove it from the mounting hole 152, the pair of mounting locking pieces 120 and the leg pieces 128 are in contact with the mounting holes 152 and the leg pieces 128. This corresponds to the force required to bend in the opposite direction at the position where it abuts against the seat member 134 so that the locking shoulder 125 can be compressed to a width that allows it to pass through the mounting hole 152.

Therefore, by changing the direction in which the clip main body 110A is attached to the seating surface member 132A, when the clip structures 112C and 112D are removed from the attached member 150, the leg pieces 128 of the clip main body 110A abut on the seating surface member 132A. A difference in state occurs, and the drag generated on the attachment locking piece 120 when the attachment member 130 is removed from the attached member 150 can be varied. Therefore, the holding load of the attachment state with respect to the to-be-attached member 150 of the attachment member 130 can be varied using the same clip main body 110A.
In the third embodiment, the escape hole 140 through which the protruding portion 129 escapes is a through hole. However, the escape hole 140 is not limited to the through hole, and the escape hole 140 may be provided as a recess on both surfaces of the seating surface member 132A.
