Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an insertion structure in which an insertion portion of an assembly member is inserted into an insertion hole penetrating the plate-like member when assembling the assembly member to the plate-like member.

  For example, there is a clip or a clamp for a vehicle as an assembly member assembled in a state where the insertion portion is inserted into a through hole provided in a plate-like member of the vehicle (see Patent Document 1). Such an assembly member is provided with an insertion locking portion which is inserted into the through hole of the plate-like member. The general insertion locking portion is capable of elastically deforming the post (post) and the outside of the post from the front end to the back of the post and approaching the post. The elastic locking piece (locking piece) is inserted into the through-hole of the plate-like member, and the elastic locking piece is locked to the peripheral portion of the through-hole to be in the retaining state. Thus, the assembling member is assembled to the plate-like member.

Unexamined-Japanese-Patent No. 10-220427

  However, in the case of such an assembly member, depending on the tolerance of the through hole, a gap is generated between the inner edge of the through hole and the insertion locking portion, and the gap causes the insertion locking portion to rattle in the through hole. There is a problem called. In particular, when a gap is generated in a direction perpendicular to the pressing direction of the elastic locking piece, rattling may occur.

  An object of the present invention is to suppress rattling and facilitate insertion of an insertion portion into a through hole in an assembly structure of an assembly member and a plate-like member which are assembled by inserting the insertion portion into the through hole. It is.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-mentioned subject, the insertion structure to the plate-like member of the present invention is
An insertion structure in which an insertion portion of the assembly member is inserted into an insertion hole passing through the plate member when the assembly member is assembled to the plate member,
The insertion portion extends to the outside of the insertion hole so as to overlap the pillar portion inserted into the insertion hole, and the column portion from the pillar portion to the inner edge of the insertion hole, and when inserted into the insertion hole An elastic piece that is pressed against the inner edge of the insertion hole in the insertion direction and elastically deformed by the pressing to be accommodated inside the insertion hole, and held and held in a state in which the inner edge is pressed outward; And a rear end portion extending from the rear end in the insertion direction to a direction orthogonal to the insertion direction;
The elastic piece and the rear end face each other with a gap interposed in the insertion direction,
The elastic piece has a front end portion of the elastic piece, which is a side pressed against the inner edge of the insertion hole when the insertion portion is inserted into the insertion hole, to the rear side in the insertion direction as it goes outward from the pillar portion It is characterized in that it is formed as an inclined portion that descends.

  According to the present invention, when the insertion portion is inserted into the insertion hole of the plate-like member, the elastic piece extending outward from the pillar portion is pushed into the insertion hole in a state of being elastically deformed. The inner edge is always kept pressed outward. Thereby, rattling of the insertion portion in the insertion hole can be suppressed. The elastic piece is formed in such a positional relationship as to interfere with the inner edge of the insertion hole when the insertion portion is inserted into the insertion hole of the plate-like member, and the tip of the elastic piece in the insertion direction is the insertion hole It is provided as an inclined part which falls to the back side of the insertion direction, so that it goes to the outside from the inner side of. Thus, even when the inclined portion of the elastic piece interferes with the inner edge portion of the insertion hole when the insertion portion is inserted into the insertion hole of the plate-like member, the outer side of the insertion hole of the elastic piece can be inserted by pushing as it is. With respect to the protruding outer portion, elastic deformation can be urged toward the inside of the insertion hole gradually. And the insertion to the insertion hole of the insertion part at this time can advance smoothly in the form which the inner edge part of the insertion hole slides on the inclination part of an elastic piece. That is, when inserting the insertion portion into the insertion hole, even if the inner edge portion of the insertion hole interferes with the elastic piece, the elastic piece can be easily accommodated inside the insertion hole if the insertion portion is pushed as it is. As described above, the elastic piece can form the accommodation state of the insertion portion pressed against the inner edge of the insertion hole.

  The elastic piece in the present invention may be formed so as to extend in a bending manner toward the inside of the insertion hole as it is farther to the outside from the column portion. According to this configuration, when the insertion portion is inserted into the insertion hole, the inner edge of the insertion hole presses the elastic piece while sliding smoothly on the elastic piece along the curved shape, and the amount of elastic deformation of the elastic piece The elastic piece can be smoothly accommodated inside the insertion hole.

  The inner edge of the insertion hole in the present invention can be formed such that a pressing section pressed against the elastic piece at the time of insertion of the insertion portion is curved in an arc shape. According to this configuration, when the insertion portion is inserted into the insertion hole, the elastic piece smoothly increases the amount of elastic deformation by sliding along the arc shape on the inner edge of the insertion hole. It can be stored smoothly inside the insertion hole. In the case of the pressing of the arc-shaped inner edge, since the inner edge is pressed in different directions, it is also possible to suppress such rattling in a plurality of directions.

  In the elastic piece according to the present invention, the elastic piece outer surface on the side facing the inner edge of the insertion hole is an inclined surface inclined such that the front side in the insertion direction is positioned inside the insertion hole than the rear side. It can be formed to According to this configuration, even when the outer surface of the elastic piece and the inner edge of the insertion hole interfere with each other when the insertion portion is inserted into the insertion hole, the inner edge of the insertion hole slides on the outer surface of the elastic piece which is an inclined surface. You can proceed with the insertion. In addition, the elastic piece causes the inclined portion to interfere and contact with the inner edge of the insertion hole, and is inserted while being elastically deformed gradually, but the position where it contacts with the inner edge in the middle is from the inclined portion to the outer surface of the elastic piece Finally, the elastic piece is accommodated inside the insertion hole in such a manner that the outer surface of the elastic piece contacts the inner edge. By forming the elastic piece outer surface as the inclined surface as described above, it is possible to smoothly carry out the above delivery. Therefore, the insertion of the insertion portion into the insertion hole becomes easier.

The figure which showed the state which the assembly member which is a modification of FIG. 1 was assembled | attached to the plate-shaped member by the cross section similar to FIG.

  Embodiments of the present invention will be described with reference to the examples shown in the drawings.

  In this embodiment, as shown in FIGS. 1 to 4, when assembling the assembling member 1 to the plate member 20, the assembling member 1 is inserted into the insertion hole 20H formed through the plate member 20 as shown in FIG. The insertion structure 30 which inserts the insertion part 5 of (1) is formed.

  Here, the assembling member 1 is a vehicle assembling part such as a clip or a clamp. The assembling member 1 has an insertion portion 5 which is inserted into the insertion hole 20H of the plate member 20, as shown in FIGS. The insertion portion 5 here integrally has the column portion 2, the rear end portion 4, and the elastic piece 10.

  The column portion 2 is a portion to be inserted into the insertion hole 20H. As shown in FIGS. 1 to 4, the column portion 2 in this case extends in a pair from the rear end portion 4 and has a hollow shape connected at its front end side. As shown in FIG. 4 (bottom view) of FIG. 5, when the column portion 2 is inserted into the insertion hole 20H, at least the front end side in the insertion direction I is the insertion direction I with respect to the plate member 20. Project to the front side.

  As shown in FIGS. 1 to 4, the rear end portion 4 is an in-plane direction side (X defined by the X direction and the Y direction orthogonal to the insertion direction I from the rear end of the column portion 2 in the insertion direction I). Shape extending in the in-plane direction of the -Y plane). As shown in FIG. 4 (bottom view) of FIG. 5, when the insertion portion 5 is inserted into the insertion hole 20H of the plate member 20, the rear end portion 4 is not inserted into the insertion hole 20H. This is a portion left behind with respect to the member 20 in the insertion direction I. The rear end 4 may be provided as a functional part that performs a predetermined function in a predetermined member. For example, as shown in FIG. 9, the rear end portion 4 has a belt 41 and a belt insertion locking portion 42, and can be a binding portion or the like for binding and holding a longitudinal member such as the wire harness WH.

  The elastic piece 10 has a shape expanding from the column portion 2 to the orthogonal direction Y side orthogonal to the insertion direction I, as shown in FIGS. 1 to 4. The elastic piece 10 here is the orthogonal direction Y side away from the pillar portion 2 from one end side in the thickness direction X of the pillar portion 2 (lower side of the pillar portion 2 in FIG. 4, right side of the pillar portion in FIG. It has a shape extending to both sides (right and left sides of the column 2 in FIGS. 2 and 4). Further, as shown in FIG. 6, the elastic piece 10 extends outward of the insertion hole 20H in a direction K diagonally crossing the inner edge 20h so as to overlap the inner edge 20h of the insertion hole 20H from the column portion 2 (See the broken line in FIG. 6). When the elastic piece 10 is inserted into the insertion hole 20H, the elastic piece 10 presses the inner edge 20h of the insertion hole 20H and is elastically deformed along with the pressure and is accommodated inside the insertion hole 20H. The accommodated elastic piece 10 is accommodated and held in a state in which the inner edge 20 h is pressed outward (in the direction of the arrows P 1 and P 1 in FIG. 6). In order to facilitate such elastic deformation, the elastic piece 10 is formed so as to sandwich the air gap 14 between it and the rear end 4 in the insertion direction I as shown in FIG. It is not connected. The elastic pieces 10 here are formed in a triangular shape extending from each of the opposing wall portions forming the column portion 2 in the direction Y side orthogonal to the axial direction (also referred to as the insertion direction I).

  In addition, as shown in FIG. 5, the insertion portion 5 is an insertion locking portion which is inserted into the insertion hole 20H in the plate member 20 and is locked to the insertion hole peripheral portion 20A. In addition to the elastic piece 10 and the rear end 4, the elastic locking piece 3 is provided. The elastic locking piece 3 extends from the front end side in the insertion direction I of the column 2 in a form of being folded back to the rear end side, and is formed so as to be elastically deformed approaching the column 2 side. The elastic locking piece 3 is inserted into the insertion hole 20H to be in a locked state with respect to the insertion hole 20H, whereby the assembling member 1 is assembled to the plate-like member 20 in a retaining state. That is, the insertion portion 5 here functions as an assembling means for assembling the assembling member 1 to the plate member 20 by providing the elastic locking piece 3. Further, the elastic locking piece 3 here has a plurality of steps of locking portions 3A on the tip end side, and changes in the hole diameter of the insertion hole 20H to be locked and changes in the plate thickness of the plate member 20. On the other hand, it can respond in the form which changes the latching part 3A to latch.

  By the way, the elastic piece 10 is provided in the insertion structure 30, and thereby, the rattling of the insertion part 5 inserted in the insertion hole 20H is suppressed. Furthermore, the elastic piece 10 is formed in a shape that facilitates the insertion operation of the insertion portion 5 into the insertion hole 20H.

  Hereinafter, the insertion of the insertion portion 5 into the insertion hole 20H will be described.

  As shown in FIG. 1 (the top view) of FIG. 5, first, the front end of the insertion portion 5 in the insertion direction I (here, the front end of the column 2) is made to face the insertion hole 20H of the plate member 20. The insertion portion 5 is pushed in the insertion direction I (that is, the penetrating direction of the insertion hole 20H) and is inserted into the insertion hole 20H. When it is inserted, as shown in FIG. 2 of FIG. 5, the elastic locking piece 3 of the insertion portion 5 interferes with and contacts the inner edge 20 h of the insertion hole 20 H, thereby preventing the insertion. By pushing in the insertion direction I, as shown in FIG. 3 of FIG. 5, the insertion portion 5 is brought into an insertion form (elastic deformation state) in which the elastic locking piece 3 is elastically deformed to the column 2 side. The insertion hole 20H can be inserted. Then, as shown in FIG. 4 (bottom view) of FIG. 5, in the insertion portion 5, the locking portion 3A of the resilient locking piece 3 is a plate-like member when the resilient locking piece 3 elastically returns after insertion. The plate-like member 20 is held in contact with the 20 insertion hole peripheral portions 20A from the front side in the insertion direction I and between the rear end 4 positioned on the rear side in the insertion direction I. This state is the insertion locking state with respect to the insertion hole 20H of the insertion portion 5, whereby the assembling member 1 is assembled to the plate-like member 20 in the retaining state.

  However, when the insertion portion 5 is inserted into the insertion hole 20H, not only the elastic locking piece 3 but also the elastic piece 10 interfere and contact with the inner edge 20h of the insertion hole 20H, and the insertion is hindered . Specifically, as shown by the broken line in FIG. 6, the elastic piece 10 extends from the column 2 to the outside of the insertion hole 20H in a direction K diagonally intersecting the inner edge 20h of the insertion hole 20H. Therefore, as shown in FIG. 1 (top view) of FIG. 7, interference / contact with the inner edge 20h of the insertion hole 20H occurs at this crossing position of the elastic piece 10 first.

  Here, the elastic piece 10 obliquely intersects the inner edge 20h of the insertion hole 20H, and as shown in FIG. 2, the elastic piece front end portion 10F forming the front end in the insertion direction I is the extension direction of the elastic piece 10 Is formed as an inclined portion which descends to the rear side in the insertion direction I as it goes to the outer side of the (i.e., the outer side far from the column portion 2). Therefore, when the insertion portion 5 is pushed in the insertion direction I, the elastic piece front end portion 10F is pressed against the inner edge 20h of the insertion hole 20H. Then, when the insertion portion 5 is further pushed in the insertion direction I by this pushing, as shown in FIG. 2 of FIG. 7, the outside of the insertion hole 20H of the elastic piece 10 is the inside (inner edge of the insertion hole 20H The entire elastic piece 10 is bent in such a manner as to be elastically deformed to the side approaching 20 h). And finally, the elastic piece 10 is accommodated inside the insertion hole 20H. This pushing progresses as the inner edge of the insertion hole 20H slides on the elastic piece front end portion 10F forming an inclined portion as shown by a two-dot chain line in FIG. 2, so the inclination of the elastic piece 10 proceeds smoothly I will.

  Further, the elastic piece 10 here extends so as to bend inward of the insertion hole 20H toward the outer side in the extension direction (that is, the outer side far from the column 2) (see FIGS. 4 and 6). See dotted line). Therefore, when the insertion portion 5 is inserted into the insertion hole 20H, the inner edge 20h of the insertion hole 20H presses the elastic piece 10 while sliding smoothly on the elastic piece 10 along the curved shape, and the elastic piece Since the amount of elastic deformation of 10 can be gradually increased, the elastic piece 10 can be smoothly accommodated inside the insertion hole 20H.

  In addition, the inner edge 20 h of the insertion hole 20 H here is curved in a circular arc in a pressing section Q (see FIG. 8) pressed against the elastic piece 10 when the insertion portion 5 is inserted. For this reason, when the insertion portion 5 is inserted into the insertion hole 20H, the elastic piece 10 smoothly slides the elastic deformation amount along the arc shape on the inner edge 20h of the insertion hole 20H. It can increase and can be accommodated smoothly inside the insertion hole 20H. Here, since both the inner edge of the insertion hole 20H and the elastic piece 10 have a curved shape, the elastic piece 10 can be accommodated more smoothly inside the insertion hole 20H.

  In the elastic piece 10, as shown in FIG. 3, the elastic piece outer surface 10c on the side facing the inner edge 20h of the insertion hole 20H is on the front side (code 10c1) in the insertion direction I is the back side (code 10c2) It forms an inclined surface inclined so that it may be located inside the insertion hole 20H more (refer the dashed-two dotted line of FIG. 3). Therefore, even when the outer surface 10c of the elastic piece and the inner edge 20h of the insertion hole 20H interfere with each other during the insertion of the insertion portion 5 into the insertion hole 20H, the inner edge 20h slides on the outer surface 10c of the elastic piece which is an inclined surface. And the insertion can proceed easily. In addition, the elastic piece 10 is inserted while causing the elastic piece front end portion 10F forming the inclined portion to interfere and contact with the inner edge 20h of the insertion hole 20H, while being elastically deformed gradually. The contact position is transferred from the elastic piece front end portion 10F forming the inclined portion to the elastic piece outer surface 10c. Finally, the elastic piece 10 is accommodated inside the insertion hole 20H such that the elastic piece outer surface 10c comes into contact with the inner edge 20h. By forming the elastic piece outer surface 10c as the inclined surface as described above, the delivery can be smoothly performed.

  Specifically, as shown in FIG. 2, in the elastic piece front end portion 10F, the inclination of the rear side portion 10F2 with respect to the insertion direction I is larger than that of the front side portion 10F1 in the insertion direction I. In the outer surface 10c, the slope of the surface 10c2 on the rear side with respect to the insertion direction I is smaller than that of the front surface 10c1 in the insertion direction I. By having such a change in inclination gradient, when the insertion portion 5 is inserted into the insertion hole 20H, the elastic piece front end portion 10F increases in insertion resistance after the gradient is switched, while the elastic piece outer surface 10c is Insertion resistance decreases after gradient switching. For this reason, delivery to the elastic piece outer surface 10c can be promoted from the elastic piece front end portion 10F forming the inclined portion.

  Furthermore, as shown in FIGS. 2 and 3, the elastic piece front end 10F has different inclinations in the front side portion 10F1 and the rear side portion 10F2 in the insertion direction I, while the elastic piece outer surface 10c is The front surface 10c1 of the insertion direction I and the rear surface 10c2 have different inclinations. Then, the switching position 10c0 of the inclination gradient on the elastic piece outer surface 10c is located on the front side in the insertion direction I than the switching position 10F0 of the inclination gradient on the elastic piece front end portion 10F. According to this configuration, in the elastic piece 10, a section J on the front side of the switching position 10c0 of the elastic piece outer surface 10c in the insertion direction I and on the rear side of the switching position 10F0 of the elastic piece front end portion 10F on the insertion direction I However, it is a section for delivering from the elastic piece front end portion 10F forming the inclined portion to the elastic piece outer surface 10c, or a section for strongly promoting the delivery. Therefore, the delivery can be smoothly performed.

  In addition, as shown in FIG. 6, in the insertion portion 5 here, the column portion 2 and the elastic piece 10 are pressed so as to press the entire insertion portion 5 in the predetermined pressing direction P1 in the insertion state into the insertion hole 20H. A projecting portion 10T is formed so as to project in the pressing direction P1 from either or both. Here, as shown in FIGS. 2 to 4, the projecting portion 10T is formed on the side of the column portion 2 in the extending direction of the elastic piece 10 and at a position closer to the rear end side in the inserting direction I. In the elastic piece outer surface 10c, a region that most protrudes in the pressing direction P1 is formed. For this reason, the elastic piece outer surface 10c forms an inclined surface which descends from the position of the protrusion 10T toward the front side in the insertion direction I, and the outside of the extension direction of the elastic piece 10 from the position of the protrusion 10T ( An inclined surface is formed to descend toward the tip portion 10E). Due to the presence of the protrusion 10T, the insertion portion 5 is accommodated in the insertion hole 20H in a press-fit manner. That is, as shown in FIG. 6, the insertion portion 5 presses the inner edge 20h of the insertion hole 20H in the pressing direction P1 (projecting direction of the projecting portion 10T) by the projecting portion 10T and the opposite direction P0. Specifically, the end 2B on the side opposite to the projecting direction of the protrusion 10T in the column 2 is an abutting portion that abuts on the inner edge 20h of the insertion hole 20H, and the inner edge 20h corresponds to the reverse direction P0. I'm pushing it. Thereby, the insertion part 5 is suppressing the rattling to the pressing direction P1 and its reverse direction P0 in the insertion state to the insertion hole 20H.

  On the other hand, as shown in FIG. 2, from the front end side of the insertion direction I of the column portion 2, the elastic locking piece 3 in this case has the pressing direction P1 and the direction Y orthogonal to the opposite direction P0 outward direction K In the insertion state into the insertion hole 20H, as shown in FIG. 6, the inner edge 20h of the insertion hole 20H faces outward (references P3 and P3). In the direction of Thereby, the insertion part 5 is also suppressed from rattling in the direction perpendicular to the pressing direction P1 and the reverse direction P0 (direction of the codes P3 and P3) in the insertion state into the insertion hole 20H.

  The elastic piece 10 is elastically deformed so as to be accommodated inside the insertion hole 20H in a state where the insertion portion 5 is inserted into the insertion hole 20H, and presses the inner edge 20h of the insertion hole 20H. Specifically, in the elastic piece 10 here, at least the outer side (tip end 10E side) of the elastic piece 10 in the extension direction presses the arc-shaped section 20 hr. The elastic piece 10 here is elastically deformed in such a manner as to conform to the shape of the arc-shaped section 20 hr so that the outside (the tip end 10E side) presses the arc-shaped section 20 hr of the inner edge 20 h of the insertion hole 20 H There is. Thereby, the elastic piece 10 presses the inner edge 20h of the insertion hole 20H in the same direction P2 as the pressing direction P1 by the protrusion 10T, and in the same direction as the outward direction P3, P3 in the orthogonal direction Y (references P4, P4). Direction) is also pressing. When the insertion portion 5 is inserted into the insertion hole 20H, first, the elastic piece 10 is elastically deformed so as to be in close contact with the arc-shaped section 20hr of the inner edge 20h of the insertion hole 20H and is accommodated inside the insertion hole 20H. (Refer to the upper figure of FIG. 8). Then, when the insertion proceeds further and the projection 10T enters the inside of the insertion hole 20H, the projection 10T is pressed in the pressing direction P1, while the outer side (tip end 10E side) of the elastic piece 10 is inserted It will be in the state which pressed said circular-arc-shaped area 20hr of inner edge 20h of hole 20H (refer the lower figure of FIG. 8).

  Although one embodiment of the present invention has been described above, this is merely an example, and the present invention is not limited to this, as long as it does not deviate from the scope of the claims, without departing from the knowledge of those skilled in the art. Based on the above, various changes such as additions and omissions are possible.

  Hereinafter, another embodiment or modification different from the above embodiment will be described. The parts having the same functions as those in the above embodiment are indicated by the same reference numerals and the detailed description is omitted. Moreover, the said Example and the following example can be implemented suitably combining in the range which a technical contradiction does not produce.

  In the above embodiment, the insertion portion 5 presses the inner edge 20h of the insertion hole 20H in the pressing direction P1 and the opposite direction P0 due to the presence of the projecting portion 10T. Thus, the entire insertion portion 5 is inserted The pressing means for pressing the inner hole edge 20 h in a predetermined direction may be provided separately from the insertion portion 5 in the assembling member 1. For example, as shown in FIG. 12 in the assembling member 1, the pressing means (elastic locking piece 3 provided on the insertion locking portion 7) for pressing the insertion portion 5 against the inner edge 20h of the insertion hole 20H in the pressing direction P1 is inserted. When provided separately from the part 5, it is not necessary to provide the insertion part 5 with a pressing means such as the protrusion 10T. In the case of the assembling member 1 of FIG. 12, the insertion locking portion 7 having a shape obtained by removing one of the elastic locking pieces 3 and the elastic pieces 10, 10 from the insertion portion 5 described above is provided in pairs; Between the insertion locking portions 7, the insertion portions 8 having a shape obtained by removing both of the elastic locking pieces 3 from the insertion portions 5 described above are provided, and each is integrated at a connecting portion not shown, It is inserted into corresponding insertion holes 27H, 28H, 27H provided in the plate-like member 20. The assembling member 1 is locked in place by the insertion locking portions 7 and 7 being inserted into the insertion holes 27H and 27H, respectively, while the elasticity of the insertion locking portions 7 and 7 is prevented. When the locking pieces 3, 3 press the inner edges 20h of the insertion holes 27H, 27H in the vertical direction in the figure, rattling in the vertical direction in the figure is suppressed. Further, the assembling member 1 forms the insertion structure 31 of the present invention in such a manner that the insertion portion 8 is inserted into the insertion hole 28H, and the elastic pieces 10 of the insertion portion 8 are inserted in the lateral direction in the drawing. By pressing the inner edge 20 h (20 hr) of the hole 28 H, rattling to the left and right in the figure is suppressed.

  In the above embodiment, it is also possible to form no projection 10T.

  Moreover, in the said Example, the insertion hole 20H is a through-hole of elliptical shape, and the insertion structure 30 which the elastic piece 10 presses also with respect to the circular-arc-shaped inner edge area 20hr is formed. The insertion hole 20H may have, for example, a rectangular shape, and the inner edge section pressed by the elastic piece 10 (the section intersecting in the state where the elastic piece 10 is not accommodated) is not limited to an arc shape. It may be linear. Further, when there is a pressing means such as the elastic locking piece 3 in the direction Y perpendicular to the pressing direction P1 and the opposite direction P0 (direction of the codes P3 and P3), for example, the insertion structure 33 of FIG. As such, the pressing in the orthogonal direction Y by the elastic piece 10 may be eliminated.

  The pressing means for pressing the insertion portion 5 against the inner edge 20h of the insertion hole 20H in a predetermined direction (for example, the direction P1 or the orthogonal direction P3, P3 etc.) sets the position of the insertion portion 5 in the insertion hole 20H to a predetermined position. In the assembling member 1, such position holding means may be provided at a position different from that of the insertion portion 5. The elastic piece 10 accommodated inside the insertion hole 20H is in an elastically deformed state, and since the inner edge 20h of the insertion hole 20H is pressed in a predetermined direction, it can be said that this elastic piece 10 is also the above-mentioned position holding means. When the pressing direction by the elastic piece 10 is only one direction, pressing means for pressing also in the direction orthogonal to that direction may be separately provided as a position holding means in the assembling member 1.

  In the above embodiment, although the insertion portion 5 is formed as an insertion locking portion which is inserted into and locked to the insertion hole 20H, a combination with the plate-like member 20 like a locking structure in the insertion locking portion The attaching means may be separately provided to the assembling member 1 and excluded from the insertion portion 5. For example, as for the assembly means with the plate-like member 20, as shown in FIG. 12, it is inserted into and locked in another insertion hole 27H, 27H which is formed separately from the insertion hole 20H in the plate-like member 20. It may be provided as an insertion part 7, 7 (insertion locking part). In the case of FIG. 12, in addition to the insertion parts 7 and 7 (insertion locking part) provided with the locking structure, the insertion part 8 from which the locking structure is eliminated is provided. The assembling means need not be limited to the above insertion locking portion.
