Furthermore, the first tongue piece 40 of this embodiment extends from the inside of the tip portions 32, 32 of the pair of arm portions 31, 31, and is located on the inside from the connecting piece 36 at the tip of the pair of arm portions 31, 31. Although the two tongue pieces 50 extend (see FIG. 4A), for example, the first tongue piece 40 is extended from the connecting piece 36 of the pair of arm portions 31 and 31, and the first tongue piece 40 is extended. The second tongue piece 50 may be extended from the connecting piece 36 outside.

  As shown in FIG. 4A, the “inner side” of the arm portion 31, the proximal end “inner side” of the first tongue piece 40, and the “inner side” of the second tongue piece 50 are the first plate part 20. And when the 2nd board part 30 is seen from the direction perpendicular | vertical with respect to the plane, it means becoming inside the arm part 31, the inside of the 1st tongue piece 40, and the inside of the 2nd tongue piece 50. FIG.

  As shown in FIGS. 1 and 4A, the first tongue piece 40 has an opening 41 through which the screw 7 is inserted, and a base end side thereof (a distal end side of the arm portion 31). ) Are connected to the inside of the distal end portions 32 of the respective arm portions 31. Moreover, the 1st tongue piece 40 is extended so that the front end side may approach the base end part 21 of the 1st board part 20 (refer FIG. 4 (B)). The inner periphery of the opening 41 has an arc shape so as to communicate with the screw insertion hole 26 of the first plate portion 20, but may have a square shape or the like.

  As shown in FIGS. 4B and 5B, the distal end portion 43 in the extending direction of the first tongue piece 40 is bent in an arc shape in a direction away from the first plate portion 20, and the arm The portion 31 is curved toward the distal end side, and the end edge 43 a is bent so as to be folded back toward the proximal end side of the arm portion 31.

  In this embodiment, the distal end portion 43 of the first tongue piece 40 forms the first locking portion A. As shown in FIGS. 2, 5, and 6, when the nut 5 is clamped by the first locking portion A of the first tongue piece 40 and the second locking portion B of the second tongue piece 50 described later. Further, the distal end portion 43 of the first tongue piece 40 is locked so as to cover a part of the radially outer side surface 5 a and / or the axial end surface 5 b of the nut 5, and is attached to the second plate portion 30. Thus, the nut 5 is retained and retained.

  In addition, as a 1st latching | locking part, seeing the 1st tongue piece 40 from the side, the front-end | tip part 43 is latched to a part of nut 5 as a substantially U shape, a substantially U shape, etc. The shape may be used and is not particularly limited.

  Furthermore, an elongated groove-like opening hole 45 is formed at the center of the front end portion 43 of the first tongue piece 40 so as to reach the end edge portion 43a. When the nut 5 is clamped by the first locking portion A and the second locking portion B, a part of the nut 5 is fitted into the opening hole 45 and is prevented from coming off (see FIG. 2, see FIGS. 5 and 6). The opening hole 45 may be formed so as to communicate with the opening 41.

  On the other hand, as shown in FIGS. 1, 4, and 5, the second tongue piece 50 is inside the connecting piece 36 at the distal end of the arm portions 31, 31, and from the inside of the base end of the first tongue piece 40. A pair of substantially chevron-shaped presser portions 51, 51 extending obliquely in a direction away from the first plate portion 20 and obliquely folded back in a direction approaching the first plate portion 20 from the tip thereof. And a stopper portion 53 extending substantially parallel to the base end portion 21 of the first plate portion 20 from between the pair of pressing portions 51, 51 toward the connecting portion 60. .

  The pair of presser portions 51 and 51 and the stopper portion 53 form the second locking portion B. There are no particular limitations on the shape and number of the presser portion 51 and the stopper portion 53.

  Then, as shown in FIGS. 2, 5, and 6, when the nut 5 is clamped by the first locking portion A of the first tongue piece 40 and the second locking portion B of the second tongue piece 50, The distal ends of the pair of presser portions 51, 51 abut against the axial end surface 5b of the nut 5, hold the nut 5 against the second plate portion 30, and hold the distal end of the stopper portion 53, The nut 5 is positioned and held with respect to the second plate portion 30 in contact with the radially outer surface 5 a of the nut 5.

  Moreover, as the 2nd latching | locking part B, what is shown, for example in FIG. 8 may be sufficient, and it does not specifically limit. The second tongue piece 50 having the second locking portion B shown in FIG. 8 has a shape that is bent in a mountain shape, and projecting pieces 55 and 55 project from both sides of the tip. And the protrusions 55 and 55 of the 2nd tongue piece 50 contact | abut diagonally upward with respect to the radial direction outer surface 5a of the nut 5, and the nut 5 is prevented from falling out and positioned.

  In this embodiment, a separate nut 5 is sandwiched between the distal end portion 43 of the first tongue piece 40 and the pressing portion 51 and the stopper portion 53 of the second tongue piece 50 to prevent the positioning and the positioning. However, at this time, the nut 5 does not need to be completely fixed, and may be held so that slight rattling occurs.

  The clip nut 10 having the above-described structure is, for example, a predetermined metal plate material having a long plate shape made of a metal material such as S60C (carbon steel for machine structure), SK5 (carbon tool steel), or SUS304 (stainless steel). It is manufactured by punching a slit or hole having a shape, bending it, and then performing a heat treatment for imparting spring properties.

  Next, the effect of the clip nut 10 having the above structure will be described.

  That is, the nut 5 separate from the clip nut 10 is disposed so as to be aligned between the distal end portion 43 of the first tongue piece 40 and the presser portions 51 and 51 and the stopper portion 53 of the second tongue piece 50. Then, as shown by the arrow in FIG. 4B, the second plate 30 is pushed in from above.

  Then, the nut 5 abuts on the edge portion 43a of the tip portion 43 of the first tongue piece 40 and the presser portions 51, 51 and is guided by these, while the tip portion 43 and the presser portion 51 of the first tongue piece 40 are guided. , 51 bends.

  When the nut 5 is further pushed in and disposed on the first tongue piece 40, the distal end portion 43 and the presser portions 51, 51 of the first tongue piece 40 are elastically restored, and a part of the nut 5 is moved to the first tongue piece. The stopper 40 is inserted into the opening hole 45 of the piece 40 and held to prevent it from coming off, the tips of the presser portions 51 and 51 abut against the axial end surface 5b of the nut 5, and the tip of the stopper 53 is held. The nut 5 is positioned and held in contact with the radially outer surface 5a of the nut 5 (see FIGS. 2, 5, and 6). In this way, the second plate portion 30 is formed by the distal end portion 43 of the first tongue piece 40 forming the first locking portion A and the presser portions 51 and 51 and the stopper portion 53 forming the second locking portion B. On the other hand, the nut 5 can be attached to the clip nut 10 by holding the nut 5 in a state of retaining and positioning.

  At this time, since the tongue piece in this embodiment is comprised from the 1st tongue piece 40 and the 2nd tongue piece 50 extended from the base end inner side of this 1st tongue piece 40, both tongue pieces 40 and 50 are comprised. When the nut 5 is pushed in and assembled between the first tongue piece 40 and the second tongue piece 50, the nut 5 can be easily bent, and the assembling workability of the nut 5 can be further improved.

  And in this clip nut 10, as mentioned above, the front-end | tip part 43 of the 1st tongue piece 40 which is the 1st latching | locking part A at the front end side of a tongue piece, and the 2nd latching on the base end side of a tongue piece The nut 5 can be attached to the first locking portion A by a simple operation of disposing and pushing the separate nut 5 between the holding portions 51 and 51 and the stopper portion 53 of the second tongue piece 50 which is the portion B. And it can be made to latch by the 2nd latching | locking part B, can be assembled | attached to the clip nut 10, and assembly workability | operativity can be improved.

  Further, the clip nut described in the above-mentioned Patent Document 1 needs to draw a holding cylinder portion for holding the nut, but the clip nut 10 according to the present invention punches a metal plate material as described above. After being formed, it is designed to be bent as appropriate, so that its formability can be improved and the thickness of the metal plate can be reduced by the amount that drawing is not necessary, The clip nut 10 can be made compact and can be reduced in weight.

  Further, since the clip nut 10 is configured to assemble a separate nut 5, the existing nut 5 can be used, the manufacturing cost can be reduced, and the plate-like member can be used. The material, thickness, etc. of the clip nut 10 can be appropriately selected according to the plate thickness of 1, and versatility can be enhanced.

  Further, in the clip nut 10 of this embodiment, the tongue piece provided with the first locking portion A and the second locking portion B for holding the nut 5 is arranged inside the pair of arm portions 31 and is connected to the connecting portion. Since it is comprised from the 1st tongue piece 40 extended toward 60, and the 2nd tongue piece 50 extended from the base end inner side of the 1st tongue piece 40, when punching and forming a metal plate material, The first locking portion A and the second locking portion B can be formed in a compact shape, and the clip nut 10 can be reduced in size. The same effect can be obtained when the second tongue piece 50 is arranged inside the pair of arm portions 31 and 31 and the first tongue piece 40 is extended from the inner side of the base end of the second tongue piece 50. Can be obtained.

  Furthermore, in this embodiment, when the nut 5 is clamped by the first locking portion A and the second locking portion B, the distal end portion 43 on the distal end side of the first tongue piece 40 is the radially outer surface of the nut 5. 5a and / or bend so as to cover a part of one end face 5b in the axial direction (see FIG. 5B and FIG. 6), so that the nut 5 is removed so as not to come off from the second plate portion 30. While being able to stop and hold, it is possible to suppress displacement of the nut 5 with respect to the opening 41 provided in the first tongue piece 40 of the second plate portion 30. Moreover, the 1st tongue piece 40 can be made into a comparatively simple shape, and a moldability can be improved more.

  Moreover, in this embodiment, when the nut 5 was clamped by the 1st latching | locking part A and the 2nd latching | locking part B, as shown in FIG. 6, it formed in the front-end | tip part 43 of the 1st tongue piece 40. Since a part of the nut 5 is fitted into the opening hole 45, the nut 5 can be more reliably prevented from coming off from the second plate portion 30.

  Furthermore, in this embodiment, when the nut 5 is clamped by the first locking portion A and the second locking portion B, the second locking portion B is formed as shown in FIGS. Since the holding portion 51 of the second tongue piece 50 abuts on the axial end surface 5b of the nut 5, the nut 5 can be held so as not to come off from the second plate portion 30.

  In this embodiment, when the nut 5 is clamped by the first locking portion A and the second locking portion B, as shown in FIGS. 5B and 6, the stopper of the second plate portion 30. Since the portion 53 contacts the radially outer surface 5a of the nut 5, the nut 5 can be held so as not to be displaced with respect to the second plate portion 30.

  As described above, after assembling the separate nut 5 to the clip nut 10, the plate-like member 1 is sandwiched from the tip side of the first plate portion 20 and the second plate portion 30, so that the plate-like member 1 is sandwiched. Then, the clip nut 10 is pushed into the through hole 2 of the plate-like member 1 until the screw insertion hole 26 of the first plate portion 20 and the opening 41 of the second plate portion 30 communicate with each other.

  At that time, the plate-like member 1 is interposed between the first plate portion 20 and the second plate portion 30 while being guided by the tip portion 23 of the first plate portion 20 and the tip portion 32 of each arm portion 31 of the second plate portion 30. Enters, and the retaining piece 25 of the first plate portion 20 is pressed and slightly bent (if the plate-like member 1 is thick, the first tongue piece 40 is also bent), and the screw insertion hole 26 is a through-hole. 2, the first tongue piece 40 comes into contact with one surface of the plate-like member 1, the retaining piece 25 is elastically restored, and the tip thereof enters the inside of the through-hole 2 to form a plate-like shape. The clip nut 10 can be attached to the member 1 while being prevented from coming off (see FIG. 6).

  Further, as described above, since the thickness of the clip nut 10 can be reduced, the clip nut 10 is pushed into the plate-like member 1 and the retaining piece 25 and the first tongue piece 40 are bent. However, when the plate-like member 1 is inserted between the first plate portion 20 and the second plate portion 30, the retaining piece 25 and the first tongue piece 40 are easily bent to reduce the insertion resistance. be able to. Further, since the insertion resistance can be lowered, even if the plate thickness of the plate-like member 1 increases, it can flexibly cope with it.

  After mounting the clip nut 10 on the plate-like member 1 as described above, the component 3 is mounted so that the mounting hole 4 communicates with the screw insertion hole 26 of the clip nut 10, the opening 41, and the screw hole 6 of the nut 5. The screw 7 is placed on the plate-like member 1 and then screwed into the screw hole 6 of the nut 5 through the mounting hole 4, the screw insertion hole 26 and the opening 41 in order, thereby screwing the head 7 a of the screw 7. Can abut on one surface of the component 3 to fix the component 3 to the plate member 1 with screws (see FIG. 7).

  At this time, in this embodiment, when the nut 5 is clamped by the first locking portion A and the second locking portion B and the plate member 1 is sandwiched and attached, as shown in FIG. Since the arm portions 31 and 31 are respectively arranged on the outer sides of the outer surfaces 5a and 5a opposed to each other in the radial direction of the nut 5 to form a rotation preventing portion, the nut 5 is prevented from rotating and the screw 7 is attached to the nut 5 The screw hole 6 can be securely screwed.

  Furthermore, in this embodiment, as shown in FIG. 4 (B) and FIG. 5 (B), the anti-rotation part provided in each arm part 31 includes the first plate part 20, the connecting part 60 and the second plate part 30. Since the parallel part 34 is formed substantially parallel to the first plate part 20 when viewed from the side, when the plate-like member 1 is thick, the first plate part 20 and the second plate part 2 are formed. Even if the plate-shaped member 1 is sandwiched between the plate portions 30, the rotation preventing portions can be disposed on both outer radial surfaces 5 a, 5 a of the separate nut 5, and the nut 5 can be more reliably prevented from rotating. it can. Note that the same effect can be obtained when the anti-rotation portion provided on the arm portion 31 is formed so as to be separated from the first plate portion 20 toward the distal end side of the arm portion.

  Further, in this clip nut 10, the nut 5 is sandwiched by the tip portion 43 of the first tongue piece 40 and the pressing portion 51 and the stopper portion 53 of the second tongue piece 50, and is prevented from being detached and positioned. Since the mounting hole 4 of the component 3, the screw insertion hole 26 of the clip nut 10, the opening 41, and the screw hole 6 of the nut 5 are in communication with each other (see FIG. 6), the screw 7 is screwed smoothly. Can be made.

  Note that, as described above, when the nut 5 is held with respect to the clip nut 10 so as to be slightly rattled, the screw 7 is inclined with respect to the axis of the screw hole 6 of the nut 5. Even if it is inserted at an angle, the nut 5 is finely moved as needed, so that the screw 7 can be screwed into the nut 5.
