Note that projecting portions 35 and 35 that slightly protrude in the slit 34 are provided on both sides of the notched portion 36, and when the engaging convex portion 60 is engaged with the notched portion 36, the projecting portions 35 and 35 Temporarily fixed. The tops of the protrusions 35, 35 are linear, and when a force greater than a predetermined value is applied to the push nut 50, the engagement convex part 60 can escape from the notch part 36 relatively easily. Further, since each notch 36 is formed on the inner periphery of each slit 34, each notch 36 can be formed simultaneously with the formation of the pair of slits 34, thereby improving the moldability of the clip 10. It has been.

  In this embodiment, the engaging projection 60 of the push nut 50 is engaged with the arc-shaped notch 36. However, instead of the notch, a hole penetrating the ceiling wall 30 or a ceiling A concave portion having a predetermined depth may be provided in the thickness direction of the wall 30 and is not particularly limited.

  A connecting portion 38 extends from the bottom surface of the head portion 20, and a flange portion 39 that spreads in an umbrella shape obliquely downward from the lower end portion of the connecting portion 38 toward the side opposite to the head portion 20. Is formed. The flange portion 39 is a portion that elastically abuts against the front side periphery of the mounting hole 7 of the mounted component 5 and suppresses rattling or the like of the clip 10. The connecting portion 38 is formed with a lightening groove 38a, 38a at a predetermined depth along the insertion direction of the push nut 50 (see FIG. 2B).

  From the lower surface of the flange portion 39, there is a locking leg 40 that is inserted into the mounting hole 7 of the mounted part 5 and that engages with the rear peripheral edge of the mounting hole 7 toward the side opposite to the head 20. It is extended. As shown in FIGS. 1 and 2 (b), the locking leg 40 includes a column portion 41 suspended from the lower surface of the flange portion 39, and an outer periphery of the column portion 41 via a predetermined gap 43. And a plurality of locking pieces 45 formed to bulge in a round shape. The base end portion of each locking piece 45 has a narrowed shape, and the intermediate portion is slightly larger in diameter than the inner diameter of the mounting hole 7 of the mounted component 5. 7 is formed with a stepped locking step 45a that engages with the rear side periphery of the plate. When each locking piece 45 is inserted into the mounting hole 7 by the gap 43 formed inside thereof, the locking piece 45 is pressed to the inner periphery thereof and bent. In addition, in this embodiment, the locking leg 40 which swelled roundly is employ | adopted, However, It is good also as a foot-shaped locking leg, and is not specifically limited.

  Next, the metal push nut 50 will be described with reference to FIG. The push nut 50 has a plate body 51 in which a circular shaft hole 53 into which the support shaft 3 is inserted is formed at the center. The plate 51 is formed with a fan-shaped opening 55 that is separated from the peripheral edge of the shaft hole 53 radially outward to form a fan shape at a predetermined opening angle. The body 51 is substantially C-shaped. Note that the fan-shaped opening 55 allows the plate 51 to bend in a direction in which both ends thereof are close to each other.

  An engaging claw 57 that engages with the outer periphery of the support shaft 3 formed in the component 1 is provided on the inner periphery of the shaft hole 53. Specifically, as shown in FIG. 3 (a), a plurality of V-shaped slits 58 are formed at predetermined intervals along the inner periphery of the shaft hole 53 and open in a V shape toward the radially inner side. A plurality of engaging claws 57 are formed by bending the strip-shaped pieces separated by the plurality of V-shaped slits 58 obliquely in the axial direction. Further, among the plurality of engaging claws 57, the distance d2 (see FIG. 4 (a)) between the distal ends of the opposing engaging claws 57, 57 is formed smaller than the outer diameter of the support shaft 3. As shown in FIG. 5, it bites into the outer periphery of the support shaft 3 inserted into the shaft hole 53. The engaging claw 57 may be formed with a plurality of protrusions protruding obliquely inward from the inner periphery of the shaft hole 53, and is not particularly limited.

  A pair of engaging convex portions 60 and 60 are fitted to the pair of cutout portions 36 and 36 at the opposite sides of the outer peripheral edge portion of the plate body 51 on the left and right sides of the fan-shaped opening 55. It is formed with. In the case of this embodiment, as shown in FIG. 3 (b), each engagement convex portion 60 is raised in a mountain shape upward from the peripheral edge of the plate body 51. Further, in FIG. As shown in (c), the outer peripheral edge side of the plate body 51 is wide and protrudes highest, gradually narrows toward the inside in the radial direction, and is inclined so as to become lower.

  The pair of engaging projections 60, 60 engage with the pair of notches 36, 36, respectively, and push nuts so that the shaft hole 53 is substantially aligned with the insertion hole 32 of the ceiling wall 30. 50 is temporarily fixed to the ceiling wall 30. In the case of this embodiment, a shaft hole 53 is formed at the center of the push nut 50 corresponding to the ceiling wall 30 in which the insertion hole 32 is formed at the center and the pair of notches 36 are formed on both sides, and a pair of both sides is formed. Since the engaging convex portions 60, 60 are provided, the shaft hole 53 is substantially aligned with the insertion hole 32 when the pair of engaging convex portions 60, 60 are engaged with the pair of cutout portions 36, 36. It has become.

  In the case of this embodiment, since the engaging convex portion 60 has the shape described above, it fits to the inner peripheral shape of the arc-shaped cutout portion 36 formed on the ceiling wall 30 and the temporary fixing of the push nut 50 is ensured. (See FIG. 4A). Further, since the engaging convex portion 60 has the shape described above, when the push nut 50 is inserted, it is difficult to be caught on the inner peripheral edge of the slit 34, it is easy to push in, and the arc-shaped cutout portion 36 is easily engaged. When the push nut 50 is moved in the storage cavity 27, the ceiling wall 30 is pushed up to easily remove the engaging protrusion 60 from the notch 36 (see FIG. 6).

  In addition, the engagement convex part 60 should just be the shape which protrudes from the board 51, and engages with the ceiling wall 30, Furthermore, the formation position of the engagement convex part 60 and the number are not specifically limited, either. It is only necessary that the push nut 50 can be temporarily fixed to the ceiling wall 30 at a position where 53 and the insertion hole 32 are substantially aligned.

  Moreover, in this embodiment, it is in the middle of a pair of engaging convex parts 60 and 60, and it is orthogonal to the insertion direction of the push nut 50 in the outer peripheral part of the board 51 used as the position which opposes the fan-shaped opening part 55. The flat portion 62 is formed with a predetermined length. The flat portion 62 becomes a portion to be pushed in when the push nut 50 is inserted into the storage cavity 27, and by positioning the portion so as to push in the portion, the pair of engaging convex portions 60, 60 are paired with the pair of notch portions 36, 60. 36 can be aligned to engage.

  Next, a procedure for fixing the component 1 to the mounted component 5 using the mounting structure of the present invention having the above configuration will be described.

  First, in order to attach the push nut 50 to the clip 10, it is necessary to separate the push nuts 50 one by one from the case in which the plurality of push nuts 50 are accommodated. At this time, as shown in FIG. 7, even if the plurality of push nuts 50 overlap, a gap is formed between the push nuts 50 by the engaging projections 60, and the plurality of push nuts 50 may be in close contact with each other. Therefore, the push nuts 50 can be easily separated and taken out one by one, and workability can be improved.

  The push nut 50 thus taken out is inserted into the storage cavity 27 through the insertion port 28 of the head 20 of the clip 10. At this time, as shown in FIG. 1, the flat portion 62 of the push nut 50 is pushed forward with a finger, the fan-shaped opening 55 of the push nut 50 is directed toward the insertion port 28 of the clip 10, and a pair of engaging projections are formed. The engagement protrusions 60, 60 of the push nut 50 are easily aligned with the pair of notches 36, 36 of the clip 10 by inserting the portions 60, 60 into the insertion port 28 with the ceiling wall 30 side. Can do.

  The push nut 50 pushed into the clip 10 is inserted into the storage cavity 27 through the insertion port 28 while being pressed inwardly and bent inward. At this time, the ceiling wall 30 in the vicinity of the insertion port 28 is slightly bent by the engagement protrusion 60, and the engagement protrusion 60 enters the slit 34, and the engagement protrusion 60 guides along the slit 34. While being pushed, the push nut 50 is further pushed into the back of the storage cavity 27. When the engaging protrusion 60 reaches the notch 36, the engaging protrusion 60 enters and engages with the inner peripheral edge of the notch 36. At the same time, the ceiling wall 30 abuts on the surface of the push nut 50, the bottom wall 23 abuts on the back surface of the push nut 50, and both front and back surfaces of the push nut 50 are sandwiched.

  The ceiling wall 30 can be bent by a pair of slits 34, 34, and the slit 34 extends in an arc shape along the peripheral wall 25, and a cutout portion 36 is provided at an intermediate portion thereof. When inserting 50, the engaging convex portion 60 can be moved along the slit 34, and further, the engaging convex portion 60 is engaged with the notch portion 36 at an intermediate position in the longitudinal direction of the slit 34. The push nut 50 can be easily inserted and temporarily fixed.

  In this way, rattling of the push nut 50 in the storage cavity 27 is suppressed, and the push-out nut 50 is prevented from coming out of the storage cavity 27. As shown in FIGS. 4 (a) and 4 (b), the shaft hole 53 is prevented. Is substantially aligned with the insertion hole 32 of the ceiling wall 30, and the push nut 50 can be temporarily fixed in the storage cavity 27.

  In this state, the support shaft 3 protruding from the component 1 is inserted into the shaft hole 53 of the push nut 50 through the insertion hole 32 of the ceiling wall 30 from above the clip 10, and the rib 25 a on the outer periphery of the head 20 is formed. Push it in until it hits the back of part 1. At this time, the metal push nut 50 is harder than the synthetic resin support shaft 3, and the distance d2 between the tips of the engaging claws 57, 57 facing each other is smaller than the outer diameter of the support shaft 3. 5, the tip of the engaging claw 57 bites into the outer periphery of the support shaft 3, whereby the engaging claw 57 engages with the outer periphery of the support shaft 3, and thus the clip 10 is connected via the push nut 50. It can be fixed to the part 1.

  In the present invention, when the support shaft 3 is inserted, the push nut 50 is temporarily placed in the storage cavity 27 with the shaft hole 53 substantially aligned with the insertion hole 32 of the ceiling wall 30 as described above. Since it is fixed, the support shaft 3 can be smoothly inserted into the insertion hole 32 and the shaft hole 53, and the fixing operation of the clip 10 to the component 1 becomes easy.

  As described above, when the locking leg 40 of the clip 10 fixed to the component 1 is inserted into the mounting hole 7 of the mounted component 5, each locking piece 45 is pressed against the inner periphery of the mounting hole 7. Then, when the locking step 45a reaches the back side of the mounting hole 7, each locking piece 45 is elastically restored, and the locking step 45a is engaged with the peripheral edge on the back side of the mounting hole 7 together with it. The flange part 39 elastically contacts the front side periphery of the attachment hole 7, the attached part 5 is sandwiched between them, and the clip 10 is fixed to the attached part 5. In this way, as shown in FIG. 5, the component 1 can be fixed to the mounted component 5 via the clip 10.

  By the way, the positions of the support shaft 3 formed on the component 1 and the mounting hole 7 of the mounted component 5 are displaced due to a dimensional error or the like, and the locking leg 40 of the clip 10 fixed to the support shaft 3 is moved. In such a case, the clip 10 can be forcibly shifted with respect to the component 1.

  That is, although the push nut 50 is temporarily fixed in the storage cavity 27, the inner diameter D2 of the storage cavity 27 is larger than the outer diameter d1 of the push nut 50, so that the push nut 50 can be moved in the storage cavity 27. Thus, the clip 10 can be shifted with respect to the component 1. That is, as shown in FIG. 6, while the ceiling wall 30 is pushed up and bent by the engaging convex portion 60, the engaging convex portion 60 is detached from the notch portion 36, and the push nut 50 is temporarily fixed in the storage cavity 27. And the push nut 50 can be displaced in the storage cavity 27. As a result, the clip 10 can be moved relative to the component 1, and the locking leg 40 of the clip 10 can be inserted into the mounting hole 7 of the mounted component 5. In this embodiment, since the rib 25a protruding higher than the ceiling wall 30 is formed on the outer periphery of the head 20 of the clip 10, the bent ceiling wall 30 does not contact the back surface of the component 1. The push nut 50 can be smoothly displaced in the storage cavity 27.

  FIG. 8 shows another embodiment of the mounting structure of the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In this embodiment, the shape of the clip 10 is different from that in the above embodiment. That is, the clip 10a in this embodiment spreads in an umbrella shape obliquely upward from the outer peripheral edge of the rib 25a that is the upper end portion of the peripheral wall 20 of the head 20 toward the side opposite to the locking leg 40. An elastic flange portion 39a that extends is formed.

  According to this embodiment, when the clip 10 is fixed to the support shaft 3 of the component 1 via the push nut 50, the elastic flange portion 39 a elastically contacts the back surface of the component 1. On the other hand, the clip 10 can be maintained and fixed in a predetermined posture without being inclined obliquely, and further, the clip 10 can be fixed to the component 1 without rattling.
