Description

  The present invention relates to a joinery including a resin frame-like member provided with a metal reinforcing material.

  In recent years, joinery in which an opening frame fixed to a building frame and a shoji frame supported by the opening frame are made of resin have been used. When such a resin fitting is used for a window device, a door device or the like, the heat insulation performance is improved, and it is effective in preventing condensation.

  However, a frame-shaped member such as a resin-made opening frame or a casing has higher temperature dependency and lower strength than a metal frame-shaped member such as aluminum. For this reason, the resin-made frame-shaped member may be deformed at a high temperature or by the weight of the shoji. Therefore, there is a configuration in which a metal reinforcing material is inserted into the hollow portion of the resin frame-like member and reinforced (see, for example, Patent Document 1).

JP 2016-142027 A

  When inserting a reinforcing material into the hollow part of the frame-like member as in the above-described prior art, the hollow part and the reinforcing material are used to absorb variations during the production of the resin-made frame-like member and the metal reinforcing material. In general, a certain amount of gap is provided between the two. If this gap is made large, the risk of assembly failure due to interference at the time of inserting the reinforcing material is reduced, and workability at the time of manufacturing is improved. However, since the frame-shaped member and the reinforcing material are displaced from each other by the amount of the large gap, the reinforcing effect of the frame-shaped member by the reinforcing material is reduced. In particular, the extruded shape made of resin has a larger variation in the shape than the metallic extruded shape due to the manufacturing method and the characteristics of the material, and this problem is likely to occur.

  In the case of a resin-made frame-like member, for example, when a metal part such as a hinge that supports the opening and closing of a shoji is fixed, a metal reinforcing material that serves as a back plate for screwing may be used. The reinforcing material in this case also needs to be able to be easily assembled to the frame-like member and at the same time be prevented from being displaced.

  The present invention has been made in consideration of the above-mentioned problems of the prior art, and provides a joinery that can improve the manufacturing efficiency and can secure the reinforcing effect of the frame member made of resin by the reinforcing material. The purpose is to do.

  A joinery according to the present invention is a joinery including a resin-made frame-like member provided with a metal reinforcing material, and the reinforcing material is applied to a first inner surface which is one inner surface of the frame-like member. It has a fastening surface that is disposed in contact and fastened and fixed to the first inner surface using a fastener, and includes a resistance applying portion that applies resistance between contact surfaces of the first inner surface and the fastening surface. And

  According to such a structure, resistance by a resistance provision part is provided between the contact surfaces of the fastening surface of a reinforcing material, and the 1st inner surface of a frame-shaped member. Thereby, the position shift of the reinforcing material fastened and fixed to the frame-like member can be prevented. As a result, a certain amount of gap can be provided between the reinforcing member and the hollow portion or the concave portion where the reinforcing member is disposed in the frame-shaped member. For this reason, it becomes easy to insert the reinforcing material into the frame-shaped member, and the manufacturing efficiency is improved.

  In the joinery according to the present invention, the resistance applying portion may be constituted by a protrusion protruding from the fastening surface. Then, when the frame-shaped member and the reinforcing material are fastened and fixed by the fastener, the metal protrusion is in a state of being bitten into the first inner surface made of resin. As a result, the reinforcing material is more firmly fixed to the frame-like member, and the reinforcing material is more reliably prevented from being displaced.

  In the fitting according to the present invention, the fastening surface may be configured to have a recess around a fastening portion formed by the fastener. If it does so, the burr | flash produced around the fastening part at the time of fastening by a fastener can be discharged | emitted to a recessed part. For this reason, it can avoid that a burr | flash is pinched | interposed between a fastening surface and a 1st inner surface, and normal fastening strength and a fastening attitude | position cannot be obtained. Further, by providing the concave portion, it is possible to avoid a burr remaining on the peripheral edge portion between the fastening surface and the first inner surface when the hole for fastening the reinforcing material or the frame-like member is formed.

  In the joinery according to the present invention, the reinforcing member is disposed in contact with the first inner surface of the frame-shaped member, and is disposed orthogonally to the fastening surface, and the first inner surface of the frame-shaped member. Is positioned on a second inner surface that is another inner surface, and a third inner surface that is disposed orthogonally to the fastening surface and is different from the first inner surface and the second inner surface of the frame-shaped member. And a resistance-applying surface disposed between the first inner surface and the fastening surface in a direction from the positioning portion toward the clearance-opposing surface. You may be set as the structure provided. If it does so, a reinforcing material can be positioned and arrange | positioned easily and reliably with respect to a frame-shaped member via a fastening surface and a positioning part. Moreover, in this positioning state, the reinforcing material has a gap formed between the gap facing surface and the third inner surface. For this reason, it is easy to insert the reinforcing material into the hollow portion or the concave portion of the frame-shaped member, and the manufacturing efficiency is high.

  In the joinery according to the present invention, the reinforcing material extends along the longitudinal direction of the frame-shaped member, and the alignment direction of the reinforcing material is the longitudinal direction of the fastening surface. A plurality of fastening holes provided to be inclined with respect to the fasteners are provided, and the first inner surface of the frame-like member is arranged along the longitudinal direction of the first inner surface, and the fastening holes and A plurality of holes that are arranged in communication and into which the fasteners are inserted may be provided. Then, the reinforcing material is disposed in a state in which the reinforcing material is inclined with respect to the longitudinal direction of the frame-shaped member in a state in which the reinforcing material is fastened and fixed to the frame-shaped member. For this reason, the reinforcing material is held in a state in which one end portion and the other end portion thereof are in contact with the opposing inner surfaces of the frame-shaped member, and the reinforcing material is displaced or rotated with respect to the frame-shaped member. Is prevented.

  The joinery according to the present invention includes an opening frame that is fixed to a housing of the building and supports a face material or a shoji, and a shoji housing that is supported by the opening frame, and at least one of the opening frame and the housing You may comprise by the said frame-shaped member. If it does so, even if it is a case where an opening frame and a housing are made from resin, the deformation | transformation can be suppressed.

  In the joinery according to the present invention, at least the opening frame is configured by the frame-shaped member, and a connecting member that connects between the shoji and the opening frame is the reinforcing member inserted into the opening frame. It may be configured to be fastened and fixed by a fastener. If it does so, the connection member which receives the weight of a shoji will be connected with respect to the reinforcement with which position shift was prevented by the resistance provision part. For this reason, it is possible to prevent the reinforcing material from being displaced due to the weight of the shoji and causing the shoji to tilt.

  According to the present invention, the production efficiency can be improved and the reinforcing effect of the resin frame-like member by the reinforcing material can be ensured.

  Next, a specific configuration of the reinforcing member 32 will be described. FIG. 4 is a diagram illustrating a configuration example of the reinforcing member 32 inserted into the hollow portion 27 of the vertical frame 14c. 5A is a cross-sectional view showing a state in which the reinforcing member 32 shown in FIG. 4 is inserted into the hollow portion 27, and FIG. 5B shows a state in which the reinforcing member 32 is fastened and fixed to the vertical frame 14c from the state shown in FIG. 5A. It is a cross-sectional view shown.

  As shown in FIGS. 4 to 5B, the reinforcing member 32 is an extruded shape member made of metal such as aluminum. The reinforcing member 32 is a rod-like member that has a substantially U-shaped cross section and extends along the longitudinal direction of the hollow portion 27 of the vertical frame 14c. The reinforcing member 32 includes a pair of side wall portions 58 and 59 that face each other, and a central wall portion 60 that connects between one end portions of the pair of side wall portions 58 and 59. The reinforcing member 32 may have a configuration in which a metal plate such as steel or stainless steel is bent into a substantially U shape.

  The central wall portion 60 is a portion that is disposed in contact with the first inner surface 27 a that is one inner surface of the hollow portion 27 and is fastened by a screw 62. That is, the outer surface of the central wall part 60 becomes the fastening surface 60a of the reinforcing material 32 with respect to the vertical frame 14c. The first inner surface 27 a is an inner surface of a wall portion that forms the outdoor-side finding surface 28 of the hollow portion 27. A fastening hole 60b into which the screw 62 is screwed is formed in the central wall portion 60 (fastening surface 60a). The first inner surface 27a is provided with a hole portion 27e that is arranged to communicate with the fastening hole 60b and through which the screw 62 is inserted. A plurality of (for example, three) fastening holes 60b and holes 27e are provided along the longitudinal direction of the reinforcing member 32 and the vertical frame 14c, respectively.

  The fastening surface 60a is provided with a plurality of protrusions 60c and a recess 60d. Each protrusion 60 c is a protrusion that protrudes from the fastening surface 60 a in a substantially triangular shape and extends in the longitudinal direction of the reinforcing member 32. Each protrusion 60c is arranged in the width direction (X direction) of the reinforcing member 32, and a total of four protrusions 60c are provided on both sides of the fastening hole 60b (recessed portion 60d). The number of protrusions 60c installed may be changed. The height of the protrusion 60c is, for example, about 1 to 20 times the plate thickness of the central wall 60, for example, if the plate thickness of the central wall 60 is 1.5 to 3 mm, the height of the protrusion 60c is It is set to about 0.1 to 1 mm. Each protrusion 60c functions as a resistance applying portion 64 that provides in-plane resistance between the first inner surface 27a and the fastening surface 60a and restricts displacement of the reinforcing member 32 in the hollow portion 27.

  The recessed portion 60d is a portion where the fastening surface 60a is lowered by the same height as the protrusion 60c, and is a shallow groove portion extending in the longitudinal direction of the reinforcing member 32. The fastening hole 60b is formed in the recess 60d. That is, the recess 60 d is provided around a fastening hole 60 b that serves as a fastening portion by the screw 62.

  One side wall portion 58 is a portion disposed in contact with the second inner surface 27 b of the hollow portion 27. The second inner surface 27b is an inner surface orthogonal to the first inner surface 27a, and is an inner surface of a wall portion that forms an outer prospective surface of the vertical frame 14c. That is, the outer surface of the side wall portion 58 becomes a positioning surface (positioning portion) 58 a that regulates the position in the direction (X direction) along the fastening surface 60 a of the reinforcing member 32 in the hollow portion 27. The reinforcing member 32 is positioned by the abutting and positioning of the fastening surface 60a and the positioning surface 58a to the first inner surface 27a and the second inner surface 27b, respectively, and the fastening hole 60b is reliably disposed corresponding to the hole portion 27e.

  The other side wall portion 59 is a portion that is disposed to face the third inner surface 27c of the hollow portion 27 via the gap C1 (see FIG. 5B). The third inner surface 27c is an inner surface that is orthogonal to the first inner surface 27a and faces the second inner surface 27b, and is an inner surface of the wall portion that forms the inner prospective surface (the shoji placement portion 18) of the vertical frame 14c. That is, the outer surface of the side wall portion 59 becomes a gap facing surface 59a that forms a gap C1 with the third inner surface 27c. The reinforcing material 32 is easily inserted into the hollow portion 27 by providing the gap C1 between the gap facing surface 59a and the third inner surface 27c.

  A gap C2 is also formed between the front end surfaces 58b, 59b of the side wall portions 58, 59 and the fourth inner surface 27d of the hollow portion 27 (see FIG. 5B). The fourth inner surface 27d is an inner surface facing the first inner surface 27a. This makes it easier to insert the reinforcing material 32 into the hollow portion 27.

  Next, the attachment structure of the reinforcing member 32 will be described.

  First, as shown in FIG. 5A, the reinforcing material 32 is inserted into the hollow portion 27 from the small opening of the vertical frame 14c. At this time, the reinforcing member 32 is inserted into the hollow portion 27 in such a posture that the surfaces 60a, 58a, 59a face the inner surfaces 27a, 27b, 27c, respectively. When the fastening surface 60a (protrusion 60c) is brought into contact with the first inner surface 27a and the positioning surface 58a is brought into contact with the second inner surface 27b, the fastening hole 60b coincides with the hole portion 27e.

  Next, as shown in FIG. 5B, the screw 62 is screwed into the fastening hole 60b through the hole 27e, and the vertical frame 14c and the reinforcing member 32 are fastened and fixed. If it does so, it will be in the state which the metal processus | protrusion 60c provided in the fastening surface 60a bite into the resin-made 1st inner surfaces 27a with the fastening force of the bis | screw 62. FIG. As a result, the reinforcing member 32 is firmly fixed in the hollow portion 27 to the vertical frame 14c. At this time, the reinforcing member 32 is prevented from being displaced in the direction of the gap C1 by the biting action of the protrusion 60c on the first inner surface 27a. That is, the protrusion 60c constituting the resistance applying portion 64 provides resistance in the in-plane direction (here, the X direction) between the contact surfaces of the first inner surface 27a and the fastening surface 60a, and the displacement of the reinforcing member 32 is prevented. The

  When the screw 62 drills the inner wall surface of the fastening hole 60b, a burr is generated, but this burr is discharged to the recess 60d. For this reason, it can be avoided that the burr is caught in the protrusion 60c, or that the proper fastening strength and fastening posture cannot be obtained due to being sandwiched between the fastening surface 60a and the first inner surface 27a. Further, by providing the recess 60d, burrs remaining on the peripheral edge of the fastening hole 60b and the hole 27e may be caught in the protrusion 60c or sandwiched between the fastening surface 60a and the first inner surface 27a. Can be avoided.

  In the joinery 10, one attachment plate 30a of the hinge 30 is disposed on the outdoor-side finding surface 28 of the vertical frame 14c, and the attachment plate 30a is fastened together with the reinforcing member 32 using screws 62 (see FIG. 5B). . Thereby, the hinge 30 (mounting plate 30a) which receives the weight of the shoji 16 can be received by the metal reinforcing material 32 instead of the resin vertical frame 14c. However, an external force toward the right in the X direction in FIG. 5A is applied to the mounting plate 30a and the reinforcing member 32 fastened thereto due to the weight of the shoji 16. However, since this external force is received by the biting force of the protrusion 60c on the first inner surface 27a, the displacement of the reinforcing member 32 in the X direction and the inclination of the shoji 16 due to this displacement are suppressed.

  In addition, since the reinforcing material 52 inserted into the hollow portion 47 of the vertical rod 36c of the shoji 16 has substantially the same structure as the above-described reinforcing material 32, the same reference numerals in FIG. Is omitted. That is, the reinforcing member 52 includes a central wall portion 60 having a fastening surface 60a, a fastening hole 60b, a protrusion 60c, and a recess 60d, a side wall portion 58 having a positioning surface 58a, and a side wall portion 59 having a gap facing surface 59a. Similarly, the hollow portion 47 into which the reinforcing member 52 is inserted and fixed has substantially the same structure as the hollow portion 27 described above, and therefore the same reference numerals are given in FIG. 3 and detailed description thereof is omitted. That is, the hollow portion 47 has a first inner surface 27a, a second inner surface 27b, a third inner surface 27c, and a fourth inner surface 27d. A screw 62 for fastening and fixing the reinforcing member 52 to the vertical rod 36c is fastened together with the other mounting plate 30b of the hinge 30 disposed on the outer prospective surface 50 of the vertical rod 36c. Thereby, the other mounting plate 30b of the hinge 30 is also fastened and fixed to the metal reinforcing member 52 instead of the resin vertical rod 36c.

  FIG. 6 is a diagram illustrating a configuration of a reinforcing member 32A according to the first modification. FIG. 7 is a cross-sectional view showing a state in which the reinforcing member 32A shown in FIG.

  As shown in FIG. 6, the reinforcing member 32 </ b> A has the same structure as that of the reinforcing member 32 shown in FIG. 4 except that one side wall portion 58 is not provided. Therefore, regarding the reinforcing material 32A, the same or similar elements as those of the above-described reinforcing material 32 are denoted by the same reference numerals and detailed description thereof is omitted, and the same applies to the following reinforcing materials 32B to 32E.

  The reinforcing material 32A has a central wall portion 60 and a side wall portion 59, and is formed in a substantially L-shaped cross section. In the reinforcing member 32A, the end surface of the central wall 60 opposite to the side wall 59 is a positioning surface (positioning portion) 58a. The positioning surface 58a of the reinforcing member 32A may be formed by a curved surface, for example.

  Therefore, when attaching the reinforcing material 32A to the vertical frame 14c, the reinforcing material 32 is inserted into the hollow portion 27 from the small opening of the vertical frame 14c as shown in FIG. Then, the fastening surface 60a (protrusion 60c) is brought into contact with the first inner surface 27a, and at the same time, the positioning surface 58a is brought into contact with the second inner surface 27b, so that the fastening hole 60b coincides with the hole portion 27e. Next, the screw 62 is screwed into the fastening hole 60b through the hole 27e to fasten and fix the vertical frame 14c and the reinforcing member 32A, and at the same time, the attachment plate 30a of the hinge 30 is fastened together. As a result, the reinforcing member 32A is attached and fixed to the vertical frame 14c in a firm fastening state in which the protrusion 60c of the fastening surface 60a bites into the first inner surface 27a.

  In addition, instead of the reinforcing material 52, a reinforcing material having the same structure as that of the reinforcing material 32A may be used for the hollow portion 47 of the vertical rods 36c and 36d of the shoji 16.

  FIG. 8 is a diagram illustrating a configuration of a reinforcing member 32B according to the second modification. FIG. 9 is a cross-sectional view showing a state in which the reinforcing member 32B shown in FIG.

  As shown in FIG. 8, the reinforcing member 32B has the same structure as the reinforcing member 32 shown in FIG. 4 except that the configuration of the central wall portion 60 is different. In the reinforcing member 32 shown in FIG. 4, one set of a plurality of protrusions 60 c and recesses 60 d is provided on the central wall portion 60. On the other hand, on the central wall portion 60 of the reinforcing member 32B, two sets of a plurality of protrusions 60c and recesses 60d are provided symmetrically in the width direction (X direction). That is, the reinforcing member 32B includes a pair of resistance applying portions 64 and 64 symmetrically.

  Accordingly, the reinforcing member 32B can be inserted and fixed to the hollow portion 27 in the same manner as the reinforcing member 32 shown in FIG. 5B, using one fastening hole 60b and the surrounding protrusions 60c and recesses 60d as shown in FIG. it can. Further, the reinforcing member 32B can be inserted and fixed in the hollow portion 27 by forming the fastening hole 60b in the center of the other projection 60c and the recessed portion 60d even in a state where the posture is reversed left and right, and the work efficiency and versatility are improved. high.

  In addition, instead of the reinforcing material 52, a reinforcing material having the same structure as the reinforcing material 32B may be used for the hollow portion 47 of the vertical rod 36c of the shoji 16.

  FIG. 10 is a cross-sectional view showing a state where the reinforcing member 32C according to the third modification is inserted into the hollow portion 27. As shown in FIG.

  As shown in FIG. 10, the reinforcing member 32C has a similar structure except that it includes a resistance applying portion 64A having a configuration different from that of the resistance applying portion 64 of the reinforcing material 32 shown in FIG. 4, and the fastening surface 60a does not have a recess 60d. It is.

  Concave and convex portions 66 are provided on the fastening surface 60a of the reinforcing material 32C. The concavo-convex shape portion 66 is a serration shape in which concavo-convex shapes extending in the longitudinal direction of the reinforcing material 32C are arranged in the width direction (X direction) of the fastening surface 60a. On the first inner surface 27a of the hollow portion 27 that comes into contact with the fastening surface 60a, an uneven shape portion 67 that meshes with the uneven shape portion 66 is provided. The concavo-convex shape portion 67 is a serration shape in which concavo-convex shapes extending in the longitudinal direction of the vertical frame 14c are arranged in the width direction (X direction) of the first inner surface 27a. These concavo-convex portions 66 and 67 constitute a resistance applying portion 64A.

  Therefore, when attaching the reinforcing material 32C to the vertical frame 14c, the reinforcing material 32C is inserted into the hollow portion 27 from the small opening of the vertical frame 14c as shown in FIG. Then, at the same time when the fastening surface 60a is brought into contact with the first inner surface 27a, the positioning surface 58a is brought into contact with the second inner surface 27b, and the fastening hole 60b is made to coincide with the hole portion 27e. Next, the screw 62 is screwed into the fastening hole 60b through the hole 27e to fasten and fix between the vertical frame 14c and the reinforcing member 32C, and at the same time, the attachment plate 30a of the hinge 30 is fastened together. Accordingly, the reinforcing member 32C is attached and fixed to the vertical frame 14c in a firm fastening state in which the concave and convex portions 66 and 67 of the fastening surface 60a and the first inner surface 27a are engaged with each other.

  In addition, an uneven portion 67 may be provided in the hollow portion 47 of the vertical rods 36c and 36d of the shoji 16 and a reinforcing material having the same structure as the reinforcing material 32C may be used instead of the reinforcing material 52.

  FIG. 11 is a cross-sectional view showing a state in which the reinforcing member 32D according to the fourth modification is inserted into the hollow portion 27. As shown in FIG.

  As shown in FIG. 11, the reinforcing member 32D has a configuration in which a recess 60d is provided on the fastening surface 60a of the reinforcing member 32C shown in FIG. 11 illustrates a configuration in which a pair of left and right recesses 60d are provided as in the reinforcing material 32B illustrated in FIG. 9, but only one recess 60d may be provided as in the reinforcing material 32 illustrated in FIG. 5B.

  Therefore, in the reinforcing material 32D, burrs and the like generated when the screws 62 perforate the inner wall surface of the fastening hole 60b can be discharged into the recess 60d. For this reason, it can avoid that a burr | flash is pinched | interposed between the fastening surface 60a and the 1st inner surface 27a, and normal fastening strength and a fastening attitude | position cannot be obtained.

  By the way, in the above-described reinforcing material 32, if the height and width of the protrusion 60c are too small, sufficient resistance is not achieved, and it is difficult to prevent displacement of the reinforcing material 32. On the other hand, if the height and width of the protrusion 60c are too large, the resin-made first inner surface 27a may be broken or lifted. Therefore, at the beginning of the design of the reinforcing member 32, the protrusion 60c may be formed with the minimum height and width, and the size of the protrusion 60c may be adjusted according to the actual thing of the vertical frame 14c and the vertical rod 36c. . This adjustment can be easily performed by, for example, appropriately shaving the projection 60c of the mold for molding the reinforcing member 32, which is an aluminum profile, and providing the build-up portion H1 on the projection 60c (see FIG. 12). is there.

  The width dimension (Z-direction dimension) of the side wall portions 58 and 59 of the reinforcing member 32 may be initially set to a minimum size, and the gap C2 in FIG. That is, if the gap C2 is too large, the backlash of the reinforcing member 32 in the hollow portion 27 increases, and the fastening hole 60b and the hole portion 27e may be misaligned when the screw 62 is fastened, thereby reducing workability. is there. On the other hand, if the gap C2 is too small, when the reinforcing member 32 is inserted into the hollow portion 27, the tip surfaces 58b and 59b may interfere with the fourth inner surface 27d and the like, and workability may be reduced. Therefore, at the beginning of the design of the reinforcing member 32, the side wall portions 58 and 59 are formed with the minimum width dimension, and the size of the side wall portions 58 and 59 is adjusted to the actual size of the vertical frame 14c and the vertical rod 36c. It is good to adjust. For this adjustment, for example, the front end surfaces 58b and 59b of the mold for molding the reinforcing member 32, which is an aluminum shape, may be appropriately cut to provide a built-up portion H2 on the front end surfaces 58b and 59b (see FIG. 13). Can be easily implemented.

  It should be noted that the shape correction of the reinforcing material 32 by the build-up portions H1 and H2 can be similarly performed for the other reinforcing materials 32A to 32D.

That is, each fastening hole 60b is provided such that the alignment direction L is inclined with respect to the longitudinal direction (vertical direction V) of the fastening surface 60a. On the other hand, as described above, the arrangement direction of the holes 27e of the vertical frame 14c coincides with the vertical direction V that is the longitudinal direction of the vertical frame 14c. That is, the holes 27e are arranged along the longitudinal direction of the first inner surface 27a.

  Therefore, when attaching the reinforcing material 32E to the vertical frame 14c, the reinforcing material 32E is inserted into the hollow portion 27, and the fastening holes 60b are fastened with screws 62 in accordance with the respective hole portions 27e. Then, as shown in FIG. 15, the reinforcing member 32E is fixed in the hollow portion 27 in a posture inclined by the inclination of the alignment direction L with respect to the longitudinal direction (vertical direction V) of the vertical frame 14c. For this reason, the reinforcing member 32E is in a state in which the positioning surface 58a at the upper end thereof is in contact with the second inner surface 27b and the gap facing surface 59a at the lower end thereof is in contact with the third inner surface 27c. As a result, when the shoji 16 is attached to the hinge 30 connected and fixed to the reinforcing material 32E as shown in FIG. 16, the reinforcing material 32E may be displaced in the clockwise direction in FIG. Is prevented. In addition, the reinforcing member 32E is provided with the resistance applying portion 64 or the resistance applying portion 64A, so that the displacement is more reliably prevented. Note that the reinforcing member 32E may not include the resistance applying portion 64 or the resistance applying portion 64A, and may simply include a configuration in which the alignment direction L of the fastening holes 60b is inclined with respect to the longitudinal direction of the fastening surface 60a.
