Japanese Utility Model Publication No. 02-033156

  In the above configuration, since the clip insertion hole is opened, the shaft portion may come off from the clip insertion hole through the opening, and there is room for improvement in this respect.

  The present invention has been completed based on the above circumstances, and an object thereof is to provide a clip mounting structure capable of suppressing a situation in which a shaft portion of a clip comes out of a clip insertion hole.

  In order to solve the above-mentioned problems, a clip mounting structure of the present invention is a clip mounting structure for mounting a clip connecting a first member and a second member to a clip seat provided on the first member. The clip seat is provided on the standing wall portion that rises from the first member to the second member side, the seat surface portion that is provided at the tip of the standing wall portion, and the clip is fixed, and the standing wall portion, A holding wall portion arranged on the side of the first member with respect to the seat surface portion, and the clip is inserted into an attached portion to be attached to the clip seat and an attachment hole formed in the second member. And a first shaft portion to be inserted into a first clip insertion hole formed in the seat surface portion, and an end of the first shaft portion on the first member side. Formed on the holding wall portion A second shaft portion inserted into the second clip insertion hole and the second shaft portion are provided, and are locked from the first member side to the hole edge portion of the first clip insertion hole in the seat surface portion. An elastic locking portion, wherein the first clip insertion hole is a closed hole that penetrates the seat surface portion in the thickness direction, and the elastic locking portion is arranged in relation to the first clip insertion hole. In the process of inserting the second shaft portion from the second member side, the second shaft portion is elastically displaced by being pressed by the seat surface portion, and as a result, the second shaft portion is allowed to be inserted into the first clip insertion hole. The gap between the second shaft portion and the inner peripheral surface of the second clip insertion hole is smaller than the gap between the first shaft portion and the inner peripheral surface of the first clip insertion hole. It has a feature.

  According to the above configuration, the first shaft portion of the clip is inserted into the first clip insertion hole, and the second shaft portion is inserted into the second clip insertion hole. Then, the elastic locking portion of the second shaft portion is locked to the seat surface portion to prevent the clip from coming off. Here, since the first clip insertion hole is a closed hole, it is possible to prevent the first shaft portion from coming off from the first clip insertion hole when the clip receives a load along the surface direction of the seat surface portion. it can. Further, in the above configuration, two types of shaft portions (first shaft portion and second shaft portion) are inserted into the corresponding insertion holes (first clip insertion hole and second clip insertion hole). . As a result, the shaft portion of the clip can be positioned on the inner surfaces of the two insertion holes, and the clip can be positioned more reliably in the surface direction of the seat surface portion. Further, the gap between the second shaft portion and the inner peripheral surface of the second clip insertion hole is smaller than the gap between the first shaft portion and the inner peripheral surface of the first clip insertion hole. Therefore, the clip can be more reliably positioned in the surface direction of the seat surface portion by the second shaft portion and the second clip insertion hole.

  In addition, the elastic locking portion is pressed against the seat surface portion in the process of inserting the second shaft portion into the first clip insertion hole from the second member side, so that the first member side As a result of the seat surface side bending and displacing with respect to the end portion of the first shaft portion, the second shaft portion is allowed to be inserted into the first clip insertion hole, and the first shaft portion is inserted into the first clip insertion hole. The second clip insertion hole may be located closer to the first member than the fulcrum when is inserted.

  If the elastic locking portion is configured such that the seating surface side flexes and deforms with the end portion on the first member side as a fulcrum, for example, compared with a configuration in which the elastic locking portion slides along the radial direction of the second shaft portion. Thus, a simpler configuration can be achieved. Here, in order to bend and deform the seating surface side of the elastic locking portion, it is preferable that there is a certain amount of clearance between the first shaft portion and the inner peripheral surface of the first clip insertion hole. However, if the gap between the first shaft portion and the inner peripheral surface of the first clip insertion hole is large, the positioning accuracy of the first shaft portion will decrease. In this regard, in the above configuration, since the gap between the second shaft portion and the inner peripheral surface of the second clip insertion hole is a relatively small gap, the second shaft portion should be inserted into the second clip insertion hole. Thus, the positioning of the clip in the surface direction can be performed more reliably.

  Further, the seat surface portion and the standing wall portion constitute a box member opened in a direction along a surface direction of a surface of the first member on the clip seat side, and the second clip insertion hole is It may be opened in the same direction as the opening direction of the box member. With this configuration, for example, the box member (the seat surface portion and the standing wall portion) and the second clip insertion hole can be formed by using one slide die.

  ADVANTAGE OF THE INVENTION According to this invention, the attachment structure of a clip which can suppress the situation which the shaft part of a clip slip | omits through an opening from a clip insertion hole can be provided.

The second shaft portion 72 to be inserted into the clip insertion hole 50A and the second shaft portion 72 are provided and are locked from the trim board 21 side to the hole edge portion of the first clip insertion hole 40A in the seat surface portion 40. And a pair of elastic locking portions 73, 73.

  As shown in FIG. 7, the holding wall portion 50 is integrally formed with the inner surface of the standing wall portion 31. The second clip insertion hole 50A is opened in the same direction as the opening direction of the clip seat 30 (downward in FIG. 7). In addition, as shown in FIG. 1, in the present embodiment, the opening direction of the clip seat 30 is the front side of the vehicle (or the rear side of the vehicle). Therefore, the second clip insertion hole 50A has a shape that opens toward the front (or rear) of the vehicle, and has a function of positioning the second shaft portion 72 either in the front or rear of the vehicle or in the vertical direction. are doing.

  The second shaft portion 72 has a substantially cylindrical shape, as shown in FIG. Thus, inside the second shaft portion 72, there is provided a housing space 72A capable of housing a part of the elastically deformable portion 73 (which will be described later in detail) that has been flexibly deformed. The elastic locking portion 73 is integrally connected to the second shaft portion 72 at the end portion on the trim board 21 side. As a result, the elastic locking portion 73 has a structure in which the seat surface portion 40 side can be elastically flexibly deformed in the radial direction of the second shaft portion 72 with the end portion on the trim board 21 side as the fulcrum P1 (see FIG. 4). ing. Further, the elastic locking portion 73 has an inclined surface 73A that extends radially outward of the second shaft portion 72 toward the door inner panel 10 side (direction opposite to the inserting direction of the clip 60 into the clip seat 30). There is. As shown in FIG. 4, the tip of the second shaft portion 72 (the lower end of FIG. 4) is inserted into the second clip insertion hole 50A. That is, when the first shaft portion 71 is inserted into the first clip insertion hole 40A, the second clip insertion hole 50A is located closer to the trim board 21 side than the fulcrum P1.

  Further, in the present embodiment, the diameters of the first clip insertion hole 40A and the second clip insertion hole 50A are set to the same value. On the other hand, the outer diameter of the first shaft portion 71 is set to a value smaller than the outer diameter of the second shaft portion 72. The hole diameter of the second clip insertion hole 50A is set to be approximately the same as the outer diameter of the second shaft portion 72. Therefore, as shown in FIG. 4, a gap S1 is provided between the first shaft portion 71 and the inner peripheral surface of the first clip insertion hole 40A. On the other hand, there is almost no gap between the second shaft portion 72 and the inner peripheral surface of the second clip insertion hole 50A. That is, the gap between the second shaft portion 72 and the inner peripheral surface of the second clip insertion hole 50A is smaller than the gap S1 between the first shaft portion 71 and the inner peripheral surface of the first clip insertion hole 40A. It A gap smaller than the gap S1 may be set between the second shaft portion 72 and the inner peripheral surface of the second clip insertion hole 50A.

  Next, the operation of this embodiment will be described. When the worker attaches the clip 60 to the clip seat 30, the second shaft portion 72 of the clip 60 is inserted into the first clip insertion hole 40A from the door inner panel 10 side. In this process, the hole edge portion of the first clip insertion hole 40A (a part of the seat surface portion 40) presses the inclined surface 73A of the elastic locking portion 73, whereby the elastic locking portion 73 is flexibly deformed, Most of the elastic locking portion 73 is housed inside the second shaft portion 72. This allows the second shaft portion 72 to be inserted into the first clip insertion hole 40A. In FIG. 4, the elastic locking portion 73 in the flexurally deformed state is denoted by reference numeral 74 and is shown by a chain double-dashed line.

  Then, the clip 60 is further pushed toward the trim board 21 side, and the second shaft portion 72 that has passed the first clip insertion hole 40A is inserted into the second clip insertion hole 50A. As a result, the tip end of the second shaft portion 72 is fitted into the second clip insertion hole 50A, and the first shaft portion 71 is inserted into the first clip insertion hole 40A. Further, as the second shaft portion 72 passes through the first clip insertion hole 40A, the elastic locking portion 73 reaches the back side (the trim board 21 side) of the seat surface portion 40, and the elastic locking portion 73 elastically returns. To do. As a result, the elastic locking portion 73 is locked from the trim board 21 side to the hole edge of the first clip insertion hole 40A. This completes the attachment of the clip 60 to the clip seat 30.

  Next, the effect of this embodiment will be described. According to this embodiment, the first shaft portion 71 of the clip 60 is inserted into the first clip insertion hole 40A, and the second shaft portion 72 is inserted into the second clip insertion hole 50A. Then, the elastic locking portion 73 of the second shaft portion 72 is locked to the seat surface portion 40, so that the clip 60 is prevented from coming off. Here, since the first clip insertion hole 40A is a closed hole, when the clip 60 receives a load along the surface direction of the seat surface portion 40, the first shaft portion 71 comes out of the first clip insertion hole 40A. Can be prevented. Further, in the above configuration, two types of shaft portions (first shaft portion 71 and second shaft portion 72) are inserted into the corresponding insertion holes (first clip insertion hole 40A and second clip insertion hole 50A). Has become. As a result, the shaft portion of the clip 60 can be positioned on the inner surfaces of the two insertion holes, and the clip 60 can be positioned more reliably in the surface direction of the seat surface portion 40. Further, the gap between the second shaft portion 72 and the inner peripheral surface of the second clip insertion hole 50A is smaller than the gap S1 between the first shaft portion 71 and the inner peripheral surface of the first clip insertion hole 40A. It Therefore, the second shaft portion 72 and the second clip insertion hole 50A can more reliably position the clip 60 in the surface direction of the seat surface portion 40.

  Further, the elastic locking portion 73 is pressed by the seat surface portion 40 in the process of inserting the second shaft portion 72 from the door inner panel 10 side into the first clip insertion hole 40A, so that the elastic locking portion 73 on the trim board 21 side is pressed. As a result of the end face being a fulcrum P1 and the seat surface portion 40 side being flexibly displaced, the second shaft portion 72 is allowed to be inserted into the first clip insertion hole 40A, and the first shaft portion 71 is inserted into the first clip insertion hole 40A. In the state in which is inserted, the second clip insertion hole 50A is located closer to the trim board 21 side than the fulcrum P1.

  If the elastic locking portion 73 is configured to be flexibly deformed on the seat surface 40 side with the end portion on the trim board 21 side as the fulcrum P1, the elastic locking portion 73 slides along the radial direction of the second shaft portion 72, for example. The configuration can be simpler than that of the configuration that is displaced. Here, in order to bend and deform the seat portion 40 side of the elastic locking portion 73, it is preferable that there is a certain gap between the first shaft portion 71 and the inner peripheral surface of the first clip insertion hole 40A. Specifically, as shown by the chain double-dashed line in FIG. 4, when the elastic locking portion 73 is flexibly deformed around the fulcrum P1, the end of the elastic locking portion 73 on the seat surface 40 side is It will pass near the one-axis portion 71. Therefore, it is preferable to reduce the diameter of the first shaft portion 71 so that the displacement of the elastic locking portion 73 is not hindered by the first shaft portion 71. Therefore, in the above-described configuration, a gap S1 (from the gap between the second shaft portion 72 and the inner peripheral surface of the second clip insertion hole 50A) is formed between the first shaft portion 71 and the inner peripheral surface of the first clip insertion hole 40A. A large gap) is provided.

  However, if the gap between the first shaft portion 71 and the inner peripheral surface of the first clip insertion hole 40A is large, the positioning accuracy of the first shaft portion 71 in the surface direction of the seat surface portion 40 will deteriorate. Therefore, in this embodiment, the holding wall portion 50 having the second clip insertion hole 50A is provided, and there is almost no gap between the second shaft portion 72 and the inner peripheral surface of the second clip insertion hole 50A. It is configured (or a gap relatively smaller than the gap S1). As a result, the second shaft portion 72 is inserted into the second clip insertion hole 50A, so that the holding wall portion 50 can hold the second shaft portion 72 in the surface direction of the seat surface portion 40, and the surface of the clip 60. Directional positioning can be performed more reliably.

  Further, the clip seat 30 of the present embodiment includes, for example, a pair of molds capable of mold closing in the plate thickness direction of the seat surface portion 40, and a slide mold orthogonal to the mold closing direction of the pair of molds (inside the clip seat 30). It can be molded by injection molding using a slide mold having a shape that follows the space. Here, if the second clip insertion hole 50 </ b> A of the holding wall portion 50 of the clip seat 30 has a shape that opens in a direction that matches the opening direction of the clip seat 30 as in the present embodiment, the internal space of the clip seat 30. The second clip insertion hole 50A can be molded by a slide mold for molding. That is, it is possible to mold the second clip insertion hole 50A together with the box member constituted by the seat surface portion 40, the standing wall portion 31, and the bottom wall portion 32 by using one slide mold.

  In the present embodiment, as shown in FIG. 1, the trim board 21 is provided with a pair of clip seats 30 and 30, and the clip seat 30 arranged in front of the vehicle is arranged so as to open rearward of the vehicle. The clip seat 30 arranged on the rear side of the vehicle is arranged so as to open toward the front side of the vehicle. That is, the second clip insertion hole 50A of the clip seat 30 arranged in the front of the vehicle regulates the displacement of the clip 60 in the vertical direction and the front of the vehicle, and the second clip insertion hole 50A of the clip seat 30 arranged in the rear of the vehicle. The clip insertion hole 50A restricts the displacement of the clip 60 in the vertical direction and the rear of the vehicle. Accordingly, the trim board 21 can be accurately positioned with respect to the door inner panel 10 in the up-down direction and the vehicle front-rear direction by the pair of clip seats 30, 30.
