Description

  The present invention relates to a member mounting structure mainly applied to the assembly of furniture and furniture.

  The most typical technique for attaching another member to one member is screw tightening using screws or bolts. However, the work of tightening or loosening a screw or the like with a screwdriver is troublesome.

As a method that does not use screws or the like, a method is conceivable in which holes are formed in both members, and fasteners such as resin molded products are inserted and fixed in these holes (see, for example, the following patent document).
JP 2006-141484 A (pages 6-7, FIG. 8, FIG. 10)

  When the fastener as in the above example is employed, it is required that the fastener is closely fitted in the hole of the member so that the attached member does not fall off carelessly. However, when a member needs to be removed, there is a dilemma that the fastener cannot be quickly removed and may cause trouble.

  An object of the present invention made in view of the above is to make it easy to attach and detach members.

  In the present invention, a first member having a face plate portion in which a locking hole is formed, a second member having a face plate portion in which an insertion hole is formed, and a state that can pass through the insertion hole and is inserted into the insertion hole. A fastener main body that locks the distal end side in the locking hole, and the second member can be attached to and detached from the fastener main body and fixed to the proximal end side of the fastener main body with respect to the first member. A mounting structure including a fastener having a retaining body to be retained as an element is configured.

  When attaching the second member to the first member, the retaining member is fastened to and integrated with the fastener body, and then the fastener is inserted into the locking hole of the first member through the insertion hole of the second member. Insert and lock. When removing the second member from the first member, the retaining member is detached from the fastener main body, and then the second member is separated from the first member by pulling out the fastener main body from the insertion hole. As described above, when the mounting structure according to the present invention is employed, the members can be easily attached and detached. In particular, when removing the second member, it is only necessary to detach the retaining member from the fastener body, and even if the fastener body is closely engaged with the locking hole of the first member, the second member is removed. It will not hinder. Since the procedure for removing the fastener main body after removing the second member is taken, the operation of extracting the fastener main body is facilitated by the absence of the second member.

  One of the proximal end side of the fastener body and the retaining body is provided with a shaft portion and an extended portion extending in the radial direction connected to the shaft portion, and the shaft portion can be inserted into the other through the extended portion. A fastening hole is provided, and the retaining member can pass through the fastening hole by rotating the retaining body around the shaft part in a state where the shaft part is inserted into the fastening hole. Is capable of selectively taking the unlocking position where it can be detached from the fastener body and the locking position where the extension part cannot pass through the fastening hole and the retaining body cannot be detached from the fastener body. The work of detaching from the fastener body is facilitated.

  If a protrusion is provided around the fastening hole to engage the extension portion at the lock position and prevent the extension portion from being relatively displaced toward the unlock position, The risk of unexpected detachment from the fastener body can be reduced, and as a result, unintentional detachment of the second member can be prevented.

  The extended portion intersects the first end surface, a first end surface facing the direction of protrusion of the protrusion, a second end surface that intersects the first end surface and faces the protrusion at the unlocked position, and the first end surface. And a third end face that faces the protrusion at the lock position, and R at a corner portion where the first end face and the second end face intersect is defined as the first end face and the third end face. If it is formed larger than R at the corner portion where the end face intersects, the third end face can easily get over the protrusion when the extended portion is displaced from the unlocked position to the locked position. . That is, the rotation operation when the retaining body is fastened to the fastener body is simplified. On the contrary, the third end face cannot get over the protrusion unless a larger operating force is applied when the extension portion is displaced from the locked position to the unlocked position. Therefore, the retaining member fixed to the fastener main body is not easily detached unexpectedly.

  Generally, the fastener has an outer shape that extends along the insertion / extraction direction. Therefore, it is not easy to insert and remove the fastener in the normal direction of the face plate portion of the first member, that is, when the space necessary for the insertion / extraction operation cannot be secured, or the fastener extended in the normal direction interferes with other members. In such a case, it is difficult to employ a method of attaching a member using a fastener. In the present invention, since it is not necessary to rotate the fastener main body with respect to the member or the locking hole, the fastener main body is inserted and removed along the direction deflected from the normal direction of the face plate portion of the first member. By doing so, it is possible to insert / extract from the direction inclined with respect to the face plate portion of the first member, and it is possible to secure a space necessary for the insertion / extraction operation and avoid interference with other members.

  Preferably, a latch having an engagement surface inclined with respect to the insertion / extraction direction of the fastener body is provided on the distal end side of the fastener body, and the engagement surface is engaged with the peripheral portion of the locking hole from the back. .

  The latch has a first engagement surface and a second engagement surface that are symmetrical with respect to an axis along the insertion / extraction direction, and the latch includes the first engagement surface and the second engagement surface. If either one is selectively engaged with the peripheral portion of the locking hole, the fastener body can be properly locked even if it is inserted in a posture rotated 180 degrees around the axis from the original posture. Can be locked in the hole. Therefore, it is not necessary to stick to the posture of the fastener when attaching the member, which contributes to improved usability.

  If the front end of the fastener body is bifurcated to allow expansion and contraction by elastic deformation, and if the latch protrudes from both outer side surfaces, the bifurcated portion of the fastener body is picked and compressed with fingers It can be extracted from the locking hole of the first member.

  The retaining member is provided with a retaining portion that extends in a direction perpendicular to the insertion / extraction direction of the fastener body and is bent so as to approach the first member, and the retaining portion abuts on the second member. If the second member is held while being elastically deformed, the action of pressing the second member to the first member can be performed.

  The first member is provided with an attachment surface portion, and the second member is provided with an attachment surface portion that comes into contact with the attachment surface portion, and the face plate portion of the second member intersects the attachment surface portion and the fastener. If the orientation of the main body is turned and the face plate portion is held by the holding body, the mounting stability of the second member is improved.

  The first member has a first mounting surface portion facing a predetermined direction and a second mounting surface portion facing a direction different from the first mounting surface portion, and the second member is A first contact surface portion that is in contact with the first attachment surface portion; and a second contact surface portion that is in contact with the second attachment surface portion, wherein the face plate portion of the second member is the first If the fastener is inserted in a direction different from that of the second contact surface portion and the second contact surface portion, and the fastener is inserted perpendicularly to the face plate portion, a plurality of contact surface portions are simultaneously attached to a plurality of attachment surface portions. Thus, the second member can be positioned.

  According to the present invention, the member can be easily attached and detached. When attaching the second member to the first member, it is only necessary to insert the fastener in which the fastener main body and the retaining body are integrated into the locking hole of the first member through the insertion hole of the second member. In this case, the fastener can be easily mounted even when working in a narrow space or when it is difficult to visually recognize the positions of the locking holes and the insertion holes. When removing the second member from the first member, the second member can be separated from the first member by pulling out the fastener body from the insertion hole only by detaching the retaining body from the fastener body. Even if the fastener body is closely engaged with the locking hole of the first member, it does not hinder the removal of the second member.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a desk to which the mounting structure of the present embodiment is applied. The desk includes a leg 2, a top plate 1 supported by the leg 2 from below, and a panel 3 (screenboard or desktop panel) supported by the leg 2 or the top plate 1 via a bracket 21. Due to the presence of the bracket 21, the top plate 1 and the panel 3 are separated by a predetermined dimension in the front-rear direction, and a power supply cord connected to a device placed on the top plate 1, such as a personal computer, a telephone, a task light, or the like.

  More specifically, as shown in FIGS. 12 to 18, the panel 3 includes a panel body 4 as a first member, an edge member 6 as a second member, and a cover member 5 as main elements. 7, the edge member 6 is attached to the front side of the panel body 4, and the cover member 5 is sandwiched between the edge member 6 and the panel body 4.

  The panel body 4 is a member having a substantially rectangular shape when viewed from the front, for example, by bending a sheet metal material, and the upper end portion thereof faces the rear end of the top plate 1 through a gap. The panel body 4 in the illustrated example is formed by joining a sub surface plate 42 to a main surface plate 41 that forms the rear surface of the panel 3 from the front by welding or the like.

  The main surface plate 41 has an upper end 411 bent at the upper edge and extending forward, a cover edge setting surface part 412 extending forward slightly after being bent slightly at the front edge of the upper end 411, and a cover edge setting. It has a front surface portion 413 that hangs downward at the front edge of the surface portion 412 and faces forward, and a retreat surface portion 414 that is bent at the lower edge of the front surface portion 413 and retracts backward.

  The sub-surface plate 42 has a channel shape in which an upper portion is opened rearward in a side sectional view. By joining the main surface plate 41 and the sub surface plate 42, the rear of the channel-shaped portion is blocked by the main surface plate 41. The face plate portion 421 facing the front of the channel-shaped portion is provided with a locking hole 422 that communicates inside and outside. The locking hole 422 is for locking the latch 81 provided on the distal end side of the fastener body 8. In the illustrated example, the locking hole 422 is a square hole.

  The edge member 6 is a metal extrusion-molded product such as aluminum. The edge member 6 includes an upright portion 61 that hangs vertically, an inclined face plate portion 62 that is refracted at the lower edge of the upright portion 61 and faces the front lower side, and is bent at the rear edge of the face plate portion 62 to be rearward. And a horizontal surface portion 63 that extends. An insertion hole 621 is formed in the face plate portion 62 so as to correspond to the locking hole 422. The insertion hole 621 is for inserting the fastener body 8. The opening size of the insertion hole 621 is larger than that of the locking hole 422, and in the illustrated example, it is a long hole that expands in the left-right direction. A collar portion 64 is formed behind the elevation surface portion 61 and in the vicinity of the boundary portion between the elevation surface portion 61 and the horizontal surface portion 63. The flange portion 64 has a bottom wall 911641 extending rearward, a back wall 642 rising upward from the rear edge of the bottom wall 911161, and an edge piece 643 extending forward and backward from the upper edge of the back wall 642. And open upward. In addition, a ridge 65 protruding upward is formed at a boundary portion between the face plate portion 62 and the horizontal surface portion 63.

  The cover member 5 is, for example, a two-color molded product made of a hard resin and a soft resin. The cover member 5 is a flexible resin 51 made of a soft resin having a substantially square shape that extends forward in a side sectional view. A hard resin base 52 that supports the flexible body 51 by being joined to the rear end is included. The base 52 includes a rear edge portion 521 that extends rearward to form the rear edge of the cover 5, a hanging portion 522 that hangs downward from the rear edge portion 521, and a lower end portion that extends rearward from the lower edge of the hanging portion 522. 523, a protruding piece portion 524 that rises upward from the rear edge of the lower end portion 523, and a protrusion 525 that protrudes rearward from the rear surface of the drooping portion 522.

  In this embodiment, the panel body 4 is attached in a state where the contact surface portion of the edge member 6 is attached to the attachment surface portion of the panel body 4. Specifically, the front surface portion 413, the retracting surface portion 414, the lower surface portion 423 of the channel-shaped portion of the sub-surface plate 42, and the face plate portion 421 function as attachment surface portions in the panel main body 4, respectively. And the upright surface part 61 in the edge member 6, the upward surface of the edge piece 643 of the collar part 64, the horizontal surface part 63, and the back surface of the protrusion 65 function as an attachment surface part, respectively.

  The fastener 7 used in this embodiment is a set of a fastener body 8 and a retaining body 9. The fastener body 8 and the retaining body 9 are resin molded products made of, for example, polyacetal resin (polyoxymethylene).

  As shown in FIGS. 2 to 5, the fastener body 8 includes a latch 81 on the distal end side, and a shaft portion 83 and an extension portion 84 on the proximal end side. The front end side of the fastener body 8 is divided into a bifurcated shape in plan view, and the bifurcated portion can be expanded and contracted in the left-right direction by elastic deformation. Therefore, the latch 81 is protruded from both outer side surfaces of the bifurcated portion. The latch 81 is tapered in plan view, and has engagement surfaces 811 and 812 in front of the hand. When the latch 81 is inserted into the locking hole 422 formed in the face plate portion 421 of the panel body 4, the engaging surfaces 811 and 812 are located at the peripheral portion of the locking hole 422 in the face plate portion 421, particularly on the left and right sides of the locking hole 422. Engage with the edge part from the back. In this embodiment, since the fastener body 8 is inserted and removed from the direction inclined with respect to the face plate portion 421, the engagement surfaces 811 and 812 also intersect the axis A along the insertion and removal direction of the fastener body 8 in side view. Inclined. Furthermore, a first engagement surface 811 and a second engagement surface 812 that are symmetrical with respect to the side view axis A are formed for each of the left and right latches 81. As shown in FIG. 13 and the like, when the latch 81 is inserted into the locking hole 422 with the upper surface of the fastener body 8 facing upward, the first engagement surface 811 comes into contact with the rear surface of the face plate portion 421 and engages. Match. At this time, the second engagement surface 812 does not contribute to the engagement. In turn, when the fastener body 8 is rotated 180 degrees about the axis A and the latch 81 is inserted into the locking hole 422 with the bottom face up, the second engagement surface 812 becomes the rear surface of the face plate portion 421. Abut and engage. At this time, the first engagement surface 811 does not contribute to the engagement. In short, regardless of the upper and lower sides of the fastener body 8, one of the engagement surfaces 811 and 812 engages with the peripheral portion of the locking hole 422. A rib 82 protruding outward is provided near the base end of the bifurcated portion, in order to prevent the fastener body 8 from entering too far into the back through the locking hole 422.

  The shaft portion 83 of the fastener body 8 extends along the axis A direction from the most proximal end of the bifurcated portion. In the illustrated example, a flat shape in which the lateral width dimension is larger than the vertical thickness dimension is formed. The extended portion 84 is connected to the most proximal end of the shaft portion 83. The extension portion 84 extends in the radial direction, that is, in the direction orthogonal to the axis line A, relative to the shaft portion 83. In the illustrated example, a rectangular thin plate shape having a left-right width dimension larger than that of the shaft portion 83 and a vertical thickness dimension substantially equal to that of the shaft portion 83 is formed. The corner portion R where the upper end surface 841 and the right end surface 844 of the front view extension 84 intersect (when the fastener main body 8 is viewed from the base end side along the axis A) is determined by the upper end surface 841 and the left end surface 843. It is larger than R of the intersecting corner portion. The corner portion R where the lower end surface 842 and the left end surface 843 of the front view extension 84 intersect is also larger than the corner portion R where the lower end surface 842 and the right end surface 844 intersect. In addition, the R of the corner portion where the upper end surface 841 of the right side view extension portion 84 and the right rear end surface 846 intersect is larger than the R of the corner portion where the lower end surface 842 and the right rear end surface 846 intersect. . In addition, the corner portion R where the lower end surface 842 of the left side view extension 84 and the left rear end surface 845 intersect is more than the corner portion R where the upper end surface 841 and the left rear end surface 845 intersect. large.

  The outer dimension of the fastener body 8 is set to a size that can pass through the insertion hole 621 formed in the face plate portion 62 of the edge member 6.

  As shown in FIGS. 6 to 8, the retaining body 9 includes a cylindrical portion 91 having a cylindrical outer shape extending in the direction of the axis A, and a retaining portion 92 that is joined to the rear end of the cylindrical portion 91 and greatly expanded in the radial direction. And a handle portion 93 protruding in the radial direction from the outer periphery of the cylindrical portion 91. The cylindrical portion 91 is a portion that engages with the proximal end side of the fastener main body 8 when the retainer 9 is fixed to the fastener main body 8, and the inner diameter is slightly larger than the left-right width dimension of the expansion portion 84. 84 can be accommodated. The rear portion of the cylindrical portion 91 is closed with a bottom wall 911 and a fastening hole 912 is formed in the bottom wall 911. The fixing hole 912 is an elongated hole having a width dimension slightly larger than the vertical thickness dimension of the front-view expanded portion 84 and expanding in the radial direction. In the illustrated example, it extends in the vertical direction. The central portion of the fastening hole 912 is formed in a round hole shape that is enlarged in the radial direction so as to be slightly larger in diameter than the lateral width dimension of the shaft portion 83. In addition, blocks 913 and 914 that protrude forward from the bottom wall 911 are provided along the periphery of the fastening hole 912. The blocks 913 and 914 exist symmetrically with respect to the center of the front-view fixing hole 912, that is, the axis A, and are located at the lower left and upper right in the illustrated example. Each of the blocks 913 and 914 has a substantially fan shape in front view extending along the circumferential direction, and one end surface thereof is a stopper surface 915 and 916 facing the expanding direction of the fastening hole 912. In addition, protrusions 917, 918, 919, and 910 are provided at locations around the fastening hole 912 that are separated from the stopper surfaces 915 and 916 by the vertical thickness dimension of the extended portion 84. In the illustrated example, projections 917 and 918 projecting forward from the bottom wall 911 and projections 919 and 910 projecting inward from the inner peripheral surface of the cylindrical portion 91 are provided.

  The retaining portion 92 is a ribbon that greatly expands in a direction orthogonal to the direction of the axis A and is bent or curved toward the rear. The extending direction of the retaining portion 92 is orthogonal to the expanding direction of the fastening hole 912. In the illustrated example, it is expanded in the left-right direction.

  The grip portion 93 is held by fingers when the retaining portion 92 is fastened to the fastener body 8, the fastener 7 is inserted into the locking hole 422, or the retaining portion 92 is detached from the fastener body 8. It is a part of. In the illustrated example, a pair projects left and right.

  In attaching the edge member 6 and the cover member 5 to the panel body 4, the retaining body 9 is fixed to the fastener body 8 in advance. First, as shown in FIG. 11, the retainer 9 is rotated 90 degrees about the axis A so that the front view shape of the extended portion 84 and the front view shape of the fastening hole 912 are matched, and then the fastening hole The extension portion 84 is inserted into the 912 and the shaft portion 83 is disposed in the fastening hole 912. At this time, the extension direction of the extension portion 84 and the expansion direction of the fastening hole 912 are in agreement with each other, the extension portion 84 can pass through the fastening hole 912, and the unlocking body 9 can be detached from the fastener body 8. Position. Thereafter, as shown in FIGS. 9 and 10, the retainer 9 is rotated 90 degrees clockwise around the shaft 83 in the drawing. Then, the extended portion 84 is relatively displaced in the cylindrical portion 91, and transitions to a region between the stopper surfaces 915 and 916 and the protrusions 917, 918, 919 and 910. At this time, the extension direction of the extension portion 84 and the expansion direction of the fastening hole 912 are inconsistent, the extension portion 84 cannot pass through the fastening hole 912, and the retaining body 9 cannot be detached from the fastener body 8. Position. The stopper surfaces 915, 916 and the protrusions 917, 918, 919, 910 hold the expansion portion 84 in the lock position and play a role of suppressing the relative displacement of the expansion portion 84.

  Incidentally, in the process in which the extension portion 84 transitions from the unlocked position to the locked position, the left rear end surface 845 and the right rear end surface 846 that are the first end surfaces facing the protruding direction of the protrusions 917 and 918 are the protrusions. 917, 918 is required, but in the unlocked position, the corner portion R between the lower end surface 842 as the second end surface facing the projection 917 and the rear end surface 845 on the left side, and the second end surface facing the projection 918. Since the corner portion R of the upper end surface 841 and the right rear end surface 846 is formed to be relatively large, the rear end surfaces 845 and 846 can easily get over the protrusions 917 and 918. At the same time, the left end surface 843 and the right end surface 844, which are first end surfaces facing the projecting direction of the projections 919 and 910, need to get over the projections 919 and 910, but the second end facing the projection 919 in the unlocked position. R of the corner portion of the lower end surface 842 and the left end surface 843 which are the end surfaces of the upper end surface, and R of the corner portion of the upper end surface 841 and the right end surface 844 which are the second end surfaces facing the protrusion 910 are relatively large. Therefore, the side end surfaces 843 and 844 can easily get over the protrusions 919 and 910.

  On the contrary, in the process in which the extension portion 84 transitions from the locked position to the unlocked position, the left rear end surface 845 and the right rear end surface 846 need to get over the protrusions 917 and 918. R of the corner portion between the upper end surface 841 that is the third end surface and the rear end surface 845 on the left side, and R of the corner portion between the lower end surface 842 that is the third end surface facing the protrusion 918 and the rear end surface 846 on the right side are relatively Because of the small shape, the rear end surfaces 845 and 846 do not easily get over the protrusions 917 and 918. At the same time, the left end surface 843 and the right end surface 844, which are first end surfaces facing the projecting direction of the projections 919 and 910, need to get over the projections 919 and 910, but the second end facing the projection 919 in the unlocked position. R of the corner portion of the lower end surface 842 and the left end surface 843 which are the end surfaces of the upper end surface, and R of the corner portion of the upper end surface 841 and the right end surface 844 which are the second end surfaces facing the protrusion 910 are relatively large. Therefore, the rear end surfaces 845 and 846 do not easily get over the protrusions 919 and 910. In general, the risk that the retaining body 9 that has been fastened is unexpectedly detached from the fastener body 8 is reduced.

  Next, the edge member 6 and the cover member 5 are brought into contact with the mounting surface portion of the panel body 4. More specifically, as shown in FIG. 12 and the like, the elevation surface portion 61 of the edge member 6 and the rear edge portion 521 of the cover member 5 are brought into contact with the front surface portion 413 of the panel body 4, so that the edge member 6 The edge piece 643 of the collar portion 64 is brought into contact with the retracting surface portion 414 of the panel body 4. At the same time, the horizontal surface portion 63 of the edge member 6 is brought into contact with the lower surface portion 423 of the channel portion of the panel body 4, and the protrusion 65 of the edge member 6 is moved to the face plate portion 421 (lower edge portion of the channel portion of the panel body 4. ). Further, the rear edge portion 521 of the cover member 5 is brought into contact with the cover edge setting surface portion 412 of the panel body 4 from above.

  Subsequently, as shown in FIG. 15, the fastener 7 is inserted along the axis A direction. The axis A is substantially perpendicular to the face plate portion 62 of the edge member 6, but is inclined non-perpendicular to the face plate portion 421 of the panel body 4. When the front end side of the fastener main body 8 is inserted into the insertion hole 621 of the edge member 6 and inserted into the locking hole 422 of the panel main body 4, the bifurcated portion of the fastener main body 8 once shrinks inward due to elastic deformation, and the latch 81 Enters the back of the face plate portion 421 through the locking hole 422, and the reduced bifurcated portion expands outward again, and any of the engagement surfaces 811 and 812 contacts the rear surface of the face plate portion 421. . As a result, as shown in FIGS. 12, 13, and 16, the fastener body 8 can be locked in the locking hole 422, and the edge member 6 can be held with respect to the panel body 4 by the holding body 9. At this time, the retaining portion 92 of the retaining member 9 is expanded in the left-right direction, and the retaining portion 92 abuts against the face plate portion 62 of the end edge member 6 and is elastically deformed to press against the face plate portion 62, thereby The edge member 6 and the cover member 5 are pressed against the panel body. The cover member 5 (the hanging portion 522) is sandwiched between the panel body 4 (the front surface portion 413) and the edge member 6 (the elevation surface portion 61). The lower end portion 523 of the cover member 5 is received by the flange portion 64 of the end edge member 6. The protrusion 525 of the cover member 5 is positioned immediately below the retracting surface portion 414 of the panel body 4, and the protrusion piece 524 of the cover member 5 is positioned immediately below the edge piece 643 of the flange portion 64 of the end edge member 6. The protrusions 525 and the protruding piece portions 524 prevent the cover member 5 from being pulled upward.

  In removing the edge member 6 and the cover member 5 from the panel body 4, the retaining body 9 is detached from the fastener body 8. That is, as shown in FIGS. 11 and 14, when the retaining member 9 is rotated 90 degrees around the shaft 83 counterclockwise in the figure, the expansion portion 84 is relatively displaced in the cylindrical portion 91, Transition from the locked position to the unlocked position. In this state, the retaining portion 92 is separated from the face plate portion 62 and faces the elevation surface portion 61 and the horizontal surface portion 63 of the edge member 6, and elastic deformation is eliminated. Then, as shown in FIG. 17, the shaft portion 83 and the extension portion 84 can be pulled out from the fastening hole 912. When the retainer 9 is detached, the fastener body 8 can be pulled out from the insertion hole 621 as shown in FIG. 18, and the fastener body 8 remains locked in the locking hole 422 of the panel body 4. The edge member 6 and the cover member 5 can be removed from the panel body. Finally, the bifurcated portion of the fastener main body 8 is picked with fingers and compressed inward to release the engagement between the latch 81 and the face plate portion 421, and the fastener main body 8 is extracted from the locking hole 422.

  According to the present embodiment, the first member 4 having the face plate portion 421 in which the locking hole 422 is formed, the second member 6 having the face plate portion 62 in which the insertion hole 621 is formed, and the insertion hole 621 pass through. The fastener main body 8 that can be inserted into the insertion hole 621 and can be attached to and detached from the fastener main body 8, and is fixed to the proximal end side of the fastener main body 8. Since the mounting structure including the fastener 7 including the retaining member 9 that retains the second member 6 with respect to the first member 4 in the state is configured, the second member 6 is connected to the first member 4. When attaching the retainer 9, the retainer 9 is fastened and integrated with the fastener body 8, and the fastener 7 is inserted into the locking hole 422 of the first member 4 through the insertion hole 621 of the second member 6. Can be locked. Even in a situation where the locking hole 422 is not directly visible as in the present embodiment, and the insertion hole 621 is open to the face plate portion 62 facing obliquely downward, which is also difficult to visually recognize, The fact that the fastener body 8 can be securely locked to the first member 4 simply by inserting the fastener main body 8 by groping greatly contributes to the simplification of the assembly process. When removing the second member 6 from the first member 4, the retaining member 9 is detached from the fastener main body 8, and then the second member 6 is removed from the insertion hole 621 by pulling the fastener main body 8. It can be separated from the member 4. When removing the second member 6, only the retaining body 9 may be detached from the fastener body 8, and the fastener body 8 may be closely engaged with the locking hole 422 of the first member 4. It does not hinder the removal of the second member 6. Moreover, since the procedure which takes out the fastener main body 8 after taking the 2nd member 6 is taken, the extraction operation | work of the fastener main body 8 becomes easy by the part which the 2nd member 6 does not interpose.

  Provided on the proximal end side of the fastener body 8 is a shaft portion 83 and an expansion portion 84 that extends in the radial direction and extends to the shaft portion 83, and the shaft portion 83 can be inserted through the retaining member 9 through the expansion portion 84. A fastening hole 912 is provided, and the extension portion 84 is moved by rotating the retainer 9 about the shaft portion 83 in a state where the shaft portion 83 is inserted into the fastening hole 912. An unlocking position where the retaining body 9 can pass through the attachment hole 912 and can be detached from the fastener body 8, and a locking position where the extended portion 84 cannot pass through the fastening hole 912 and the retaining body 9 cannot be detached from the fastener body 8. Since it can be taken selectively, the work of detaching the retaining body 9 from the fastener body 8 is facilitated.

  Protrusions 917, 918, 919, 910 that engage with the extended portion 84 in the locked position around the fixing hole 912 and suppress the relative displacement of the extended portion 84 toward the unlocked position. Since the retaining member 9 is unexpectedly detached from the fastener main body 8, it is possible to prevent the second member 6 from unintentionally falling off.

  The extended portion 84 has a first end surface facing a direction opposite to the protruding direction of the protrusions 917, 918, 919, 910, and the protrusions 917, 918, 919, intersecting the first end surface and in the unlocked position. A second end face that faces 910 and a third end face that intersects the first end face and faces the protrusions 917, 918, 919, and 910 at the locked position, and the first end face and the second end face Since the corner portion R where the first end surface intersects with the third end surface is formed to be larger than the corner portion R where the first end surface intersects with the third end surface, the extended portion 84 is locked from the unlock position. The third end face can get over the protrusions 917, 918, 919, 910 relatively easily when displaced to the position. That is, the rotation operation when the retaining body 9 is fixed to the fastener body 8 is simplified. On the contrary, the third end face cannot get over the protrusions 917, 918, 919, and 910 unless a larger operating force is applied when the extension portion 84 is displaced from the locked position to the unlocked position. Therefore, the retaining body 9 fixed to the fastener body 8 is unlikely to be unexpectedly detached.

  In this embodiment, it is not necessary to rotate the fastener main body 8 with respect to the member or the locking hole 422 (around the axis A), so the fastener main body 8 is normal to the face plate portion 421 of the first member 4. It is possible to insert / extract along the direction deflected from the direction, in other words, to insert / extract from the direction inclined with respect to the face plate portion 421 of the first member 4, It is possible to avoid interference with the member. Further, regardless of the shape of the locking hole 422, it is not necessary to make the locking hole 422 large, so that the first member 4 is not weakened.

Therefore, the fastener main body 8 can be reliably locked via the latch 81.

  The latch 81 has a first engagement surface 811 and a second engagement surface 812 that are symmetrical with respect to the axis A along the insertion / extraction direction, and the first engagement surface 811 and the second engagement surface. Since any one of the mating surfaces 812 is selectively engaged with the peripheral portion of the locking hole 422, the fastener body 8 is rotated 180 degrees around the axis A from the original posture. Even if it is inserted, it can be properly locked in the locking hole 422. Therefore, it is not necessary to stick to the posture of the fastener 7 when attaching the member, which contributes to improved usability.

  The front end side of the fastener body 8 is formed into a bifurcated shape to enable expansion / contraction by elastic deformation, and the latch 81 is protruded from both outer side surfaces thereof, so that the bifurcated portion of the fastener body 8 is picked with fingers and compressed. Then, it can be extracted from the locking hole 422 of the first member 4.

  The retaining body 9 is provided with a retaining section 92 that extends in a direction perpendicular to the insertion / extraction direction of the fastener body 8 and is bent so as to approach the first member 4, and the retaining section 92 is provided in the second section. Since the second member 6 is held while abutting on the member 6 and elastically deforming, the second member 6 can be pressed against the first member 4.

  The first member 4 is provided with attachment surface portions 413, 414, 423, 421, and the second member 6 is provided with attachment surface portions 61, 643, 63, 65 which are attached to the attachment surface portions 413, 414, 423, 421.
