Description

[Technical Field]

[0001] The present invention relates to a stationary body. [Background technology]

[0002] Patent Document 1 discloses a floor fixing device as an example of a fixed body. The floor fixing device disclosed in Patent Document 1 fixes furniture, which is an example of an installed body, to a floor. The floor fixing device includes a pair of fixing brackets. Each of the pair of fixing brackets includes a bottom wall, an upright wall, and a top wall. The bottom wall is provided on one end side of the fixing bracket, and the top wall is provided on the other end side of the fixing bracket. The upright wall connects the bottom wall and the top wall. Each of the bottom wall and the top wall extends in a direction perpendicular to the upright wall and in opposite directions.

[0003] The bottom wall is fixed to the floor. An open groove is provided in the top wall. The open groove opens to the other end of the fixing bracket. The top wall is positioned above the base of the adjuster provided on the furniture. Therefore, the base is positioned between the floor and the top wall. In the floor fixing device, the opening directions of the open grooves of both fixing brackets are opposed, and the top walls are overlapped in the vertical direction. A closed shaft passage is formed between both open grooves. The shaft portion of the adjuster is trapped in the shaft passage portion. This prevents the shaft portion from slipping out toward the open end of the open groove, so the adjuster is held in place by the floor fixing device. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-161475 Summary of the Invention [Problem to be solved by the invention]

[0005] In the floor fixing device of Patent Document 1, when furniture attempts to move upward due to vibrations such as an earthquake, an upward force is applied from the base to the top wall of the fixing bracket. This upward force causes the top wall to deform. When the top wall deforms, it is no longer able to maintain its perpendicular angle to the standing wall. Of the top walls that overlap in the vertical direction, the upper top wall is more susceptible to deformation than the lower top wall because it must suppress deformation using only its own rigidity. Furthermore, although the force applied to the lower top wall is supported by the upper top wall, deformation of the upper top wall also causes the lower top wall to deform.

[0019] An embodiment of the fixed body will be described below with reference to FIGS. As shown in Fig. 1, the fixed body 10 fixes the installation body 90, which is installed on the installation surface F, to the installation surface F. The fixed body 10 prevents the installation body 90 from falling over or moving due to an earthquake.

[0020] <Installation object> 1, 2, and 6, the installation surface F is the floor surface. However, the installation surface F may be changed as appropriate as long as it is a surface on which the installation body 90 can be installed. The installation body 90 may be any surface, such as a home TV stand, an office copier, or a shelf.

[0021] The installation body 90 includes a support leg 91. The support leg 91 includes a base 93 that is placed on the installation surface F, and a shaft portion 92 that extends upward from the base 93. The base 93 includes a base main body 93a and a nut 93b. The base main body 93a includes a disk-shaped portion and a conical cylindrical portion above the cylindrical portion. The nut 93b is placed on the upper surface of the conical cylindrical portion. The nut 93b is threadedly engaged with the shaft portion 92 and restricts the upward movement of the base main body 93a. The lower surface of the base 93 is placed on the installation surface F. The shaft portion 92 extends upward beyond the upper surface of the nut 93b, which is the upper surface of the base 93. The diameter of the shaft portion 92 is smaller than the diameter of the base 93.

[0022] As shown in Figures 1 and 4, there are two types of installation bodies 90: a first installation body 90A and a second installation body 90B. The first installation body 90A and the second installation body 90B have different diameters of the shaft portions 92 of the support legs 91. The first support leg 91A, which is the support leg of the first installation body 90A, has first opposing outer surfaces 94A that face each other across a first width W1. The first width W1 is the diameter of the first shaft portion 92A of the first support leg 91A.

[0023] The second support leg 91B of the second installation body 90B has second opposing outer surfaces 94B that face each other across a second width W2. The second width W2 is the diameter of the second shaft portion 92B of the second support leg 91B. The second width W2 is greater than the first width W1. The diameter and outer shape of the base 93 of the first installation body 90A and the base 93 of the second installation body 90B may be the same or different.

[0024] 1, 2, 3, and 5, the fixed body 10 is formed by assembling a first divided body 20 and a second divided body 40. As will be described in detail later, each of the first divided body 20 and the second divided body 40 includes a fixed portion 22 that is fixed to an installation surface F, and a pair of extending arms 36 that extend from the fixed portion 22 and define an arrangement space 37 in which the shaft portion 92 is arranged.

[0025] <First division body and second division body> The first divided body 20 includes a fixing member 21 and a first holding member 31. The second divided body 40 includes a fixing member 21 and a second holding member 41.

[0026] The common configuration between the first divided body 20 and the second divided body 40 will be described. Each of the fixing members 21 includes a fixing portion 22 and an upright plate portion 23. The fixing portion 22 and the upright plate portion 23 are integral. The fixing member 21 is formed by bending a rectangular metal plate so that a crease is formed in the long side direction, and by forming a female screw 24 and a positioning hole 25, which will be described later. The crease is formed closer to one side than the center in the short side direction of the rectangular metal plate.

[0027] The fixed portion 22 is fixed to the installation surface F. The fixed portion 22 has a rectangular plate shape. When the fixed portion 22 is viewed in the plate thickness direction, the direction in which the long sides of the fixed portion 22 extend is defined as a first direction X, and the direction in which the short sides of the fixed portion 22 extend is defined as a second direction Y.

[0028] The fixing portion 22 has an adhesive surface 22a on a first surface in the plate thickness direction, and an opposite surface 22b on a second surface in the plate thickness direction. The adhesive surface 22a and the opposite surface 22b are each rectangular. An adhesive mat 12 is attached to the adhesive surface 22a. Therefore, on the underside of the fixing portion 22, there is formed an adhesive surface 22a of the adhesive mat 12, which is adhesive and can be attached to the installation surface F. The adhesive mat 12 is made of an adhesive gel-like ultra-soft urethane. The adhesive mat 12 is elastically deformable. The adhesive mat 12 has adhesive surfaces 12a on both sides in the plate thickness direction. One adhesive surface 12a of the adhesive mat 12 is attached to the adhesive surface 22a of the fixing portion 22. The other adhesive surface 12a of the adhesive mat 12 is attached to the installation surface F. When the stationary body 10 is not in use, a release paper (not shown) is attached to the other adhesive surface 12a of the adhesive mat 12.

[0029] When fixing the fixing body 10 to the installation surface F, the release paper is peeled off from the other adhesive surface 12a, and the fixing part 22 is fixed to the installation surface F by the adhesive mat 12. By fixing the fixing part 22 to the installation surface F by the adhesive mat 12, the first divided body 20 and the second divided body 40 are fixed to the installation surface F.

[0030] The standing plate portion 23 is in the shape of a rectangular plate extending along one long side of the fixed portion 22 . 2, the standing plate portion 23 has an inner surface 23a on one surface in the plate thickness direction and an outer surface 23b on the other surface in the plate thickness direction. The inner surface 23a and the outer surface 23b each have a rectangular shape. The inner surface 23a is a surface that continues to the attachment surface 22a of the fixing portion 22. The outer surface 23b is a surface that continues to the opposite surface 22b of the fixing portion 22. In a side view of the fixing member 21 seen from the outside along the first direction X, the attachment surface 22a and the inner surface 23a intersect, and the opposite surface 22b and the outer surface 23b intersect.

[0031] In a side view of the fixing member 21, of the angles formed between the fixing portion 22 and the standing plate portion 23, the angle formed between the opposite surface 22b and the outer surface 23b is an obtuse angle. The standing plate portion 23 stands obliquely upward so as to move away from the adhesive surface 22a of the fixing portion 22. Therefore, the standing plate portion 23 is inclined with respect to the adhesive surface 22a. The dimension of the fixing portion 22 in the short side direction is greater than the dimension of the standing plate portion 23 in the short side direction.

[0032] As shown in Fig. 3, female screws 24 are formed on both sides of the standing plate portion 23 in the first direction X. The female screws 24 penetrate the standing plate portion 23 in the plate thickness direction. A positioning hole 25 is formed in the center of the standing plate portion 23 in the first direction X. The positioning hole 25 penetrates the standing plate portion 23 in the plate thickness direction. When the standing plate portion 23 is viewed from the outer surface 23b, the positioning hole 25 has a rectangular shape with its long sides extending in the direction of the short sides of the standing plate portion 23.

[0033] <First holding member and second holding member> The first holding member 31 includes a base 33, extending arms 36 on both sides of the arrangement space 37, a connecting plate 35, and a first connecting wall 38. The second holding member 41 includes a base 33, extending arms 36 on both sides of the arrangement space 37, a connecting plate 35, a groove-forming piece 43, and a second connecting wall 45. The extending arms 36 on both sides of the arrangement space 37 are referred to as a "pair of extending arms 36." The base 33 and the pair of extending arms 36 have the same configuration in the first holding member 31 and the second holding member 41. Each of the first holding member 31 and the second holding member 41 is formed by bending a rectangular metal plate so that a crease is formed in the long-side direction and then processing each portion. The crease is formed closer to one side of the rectangular metal plate in the short-side direction than the center. The connecting plate portion 35 has the same configuration as the first holding member 31 and the second holding member 41 except that the dimensions are different.

[0034] When the base 33 is viewed in the plate thickness direction, the direction in which the long sides of the base 33 extend coincides with the first direction X of the fixing portion 22, and the direction in which the short sides of the base 33 extend coincides with the second direction Y. Therefore, the direction in which the long sides of the base 33 extend is the first direction X of the first holding member 31 and the second holding member 41, and the direction in which the short sides of the base 33 extend is the second direction Y of the first holding member 31 and the second holding member 41.

[0035] The pair of extension arms 36 extend from one of a pair of long sides of the base 33. The pair of extension arms 36 extend from the center of the base 33 in the first direction X. The direction in which the extension arms 36 extend from the base 33 coincides with the second direction Y. The base end of the extension arm 36 is the end closer to the base 33 in the second direction Y, and the tip of the extension arm 36 is the end opposite the base 33 in the second direction Y. The pair of extension arms 36 face each other with a gap in between in the first direction X. An arrangement space 37 is defined between the pair of extension arms 36 in the first direction X. The arrangement space 37 is capable of receiving the shaft 92 from the tip side of the extension arm 36 toward the base end.

[0036] The arrangement space 37 penetrates the first holding member 31 and the second holding member 41 in the plate thickness direction and extends longitudinally in the second direction Y. The dimension of the arrangement space 37 in the second direction Y is greater than the diameter of the shaft portion 92. The second direction Y is one of the directions perpendicular to the up-down direction Z. The arrangement space 37 opens to the outside from one end edge of the first holding member 31 and the second holding member 41 in the second direction Y at the tip of the pair of extending arm portions 36.

[0037] As shown in FIG. 4 , the first holding member 31 and the second holding member 41 have a pair of first demarcating surfaces 37a that define the arrangement space 37 and a second demarcating surface 37b that connects the pair of first demarcating surfaces 37a. When the first holding member 31 and the second holding member 41 are viewed in the thickness direction of the extension arm 36, the pair of first demarcating surfaces 37a face the first direction X and are parallel to each other. Note that the pair of first demarcating surfaces 37a do not have to be parallel to each other. For example, the distance between the pair of first demarcating surfaces 37a may increase toward the tip of the extension arm 36. The shaft 92 of the support leg 91 can be inserted into the arrangement space 37 from the tip side of the extension arm 36, i.e., from the opening side of the arrangement space 37.

[0038] The distance between the pair of first demarcating surfaces 37a in the first direction X is greater than the first width W1 of the first support leg 91A. Furthermore, the distance between the pair of first demarcating surfaces 37a in the first direction X is slightly greater than the second width W2 of the second support leg 91B. Therefore, the arrangement space 37 can accommodate both the first shaft portion 92A of the first support leg 91A and the second shaft portion 92B of the second support leg 91B.

[0039] In the arrangement space 37, the deepest position in the second direction Y is defined as the innermost portion 37c. The innermost portion 37c is the center point of the second demarcated surface 37b. The second demarcated surface 37b including the innermost portion 37c is the base end of the arrangement space 37. When the first shaft portion 92A of the first support leg 91A is brought into contact with the innermost portion 37c, a large gap is formed between the first opposing outer surface 94A of the first shaft portion 92A and the first demarcated surface 37a.

[0040] The connecting plate portion 35 extends from one of a pair of long sides of the base portion 33, opposite the long side from which the extending arm portion 36 extends. The connecting plate portion 35 extends from the entire long side of the base portion 33. The connecting plate portion 35 is bent relative to the base portion 33. The connecting plate portion 35 has an inner surface 35a on one side in the plate thickness direction and an outer surface 35b on the other side in the plate thickness direction. Each of the inner surface 35a and the outer surface 35b has a rectangular shape. The base portion 33 and the connecting plate portion 35 intersect. When the connecting plate portion 35 is viewed from the outside in the first direction X, the angle formed between the base portion 33 and the connecting plate portion 35 is an obtuse angle. The angle formed between the base portion 33 and the connecting plate portion 35 is the same as the angle formed between the fixing portion 22 and the standing plate portion 23.

[0041] Through holes 35c are formed on both sides of the connecting plate portion 35 in the first direction X. The through holes 35c penetrate the connecting plate portion 35 in the plate thickness direction. As shown in FIG. 7 , the connecting plate portion 35 has a protrusion 35d in the center in the first direction X. The protrusion 35d protrudes from the inner surface 35a of the connecting plate portion 35. When the connecting plate portion 35 is viewed from the inner surface 35a, the protrusion 35d has the shape of an elongated rectangular plate whose long sides extend in the direction of the short sides of the connecting plate portion 35. The protrusion 35d is fitted into the positioning hole 25 of the standing plate portion 23.

[0042] As shown in FIG. 2, the length of the connecting plate portion 35 of the first holding member 31 in the short side direction is referred to as "length L1." The length of the connecting plate portion 35 of the second holding member 41 in the short side direction is referred to as "length L2." Length L1 is shorter than length L2. Note that length L1 may be the same as length L2 or may be longer than length L2.

[0043] Next, the first holding member 31 will be described. As shown in Fig. 3, the first connecting wall 38 extends from one of the pair of extending arm portions 36. The first connecting wall 38 extends in the plate thickness direction of the extending arm portion 36. The first connecting wall 38 extends downward from the one of the extending arm portions 36. A screw portion 38a is formed in the center of the first connecting wall 38 in the second direction Y. The screw portion 38a is an internal thread.

[0044] The first connecting wall is spaced apart from the base 33 in the second direction Y. Therefore, a gap 39 exists between the base 33 and the first connecting wall . Next, the second holding member 41 will be described.

[0045] As shown in FIGS. 3 and 5, the groove forming piece 43 extends from the other of the pair of extending arm portions 36. The groove forming piece 43 includes an extending piece 43a and a lower abutting portion 43b. The extending piece 43a extends in the thickness direction of the other extending arm portion 36. The extending piece 43a extends downward from the other extending arm portion 36. The lower abutting portion 43b extends from the lower end of the extending piece 43a toward the one extending arm portion 36. The lower abutting portion 43b is spaced apart from the other extending arm portion 36 in the up-down direction Z. A slide groove 44 is defined between the other extending arm portion 36, the extending piece 43a, and the lower abutting portion 43b. The distance between the other extending arm 36 and the lower contact portion 43b is slightly larger than the dimension in the plate thickness direction of the extending arm 36. Therefore, the other extending arm 36 of the first divided body 20 can be inserted into the slide groove 44.

[0046] The second connecting wall 45 extends from one of the pair of extending arm portions 36. The second connecting wall 45 extends downward from the one of the extending arm portions 36. The second connecting wall 45 extends in the plate thickness direction of the extending arm portion 36. A through hole 45a is formed in the center of the second connecting wall 45 in the second direction Y. The through hole 45a is an elongated hole that extends longitudinally in the second direction Y. The through hole 45a has a first end 451 and a second end 452 in the second direction Y. The first end 451 is the end closest to the connecting plate portion 35. The second end 452 is the end opposite the first end 451 in the second direction Y. The through hole 45a is an elongated hole that extends longitudinally in the second direction Y (which is one direction), and whose dimension in the up-down direction Z is greater than the diameter of a shank 16a of an assembly bolt 16 (described later). The second connecting wall 45 is spaced apart from the base 33 in the second direction Y. Therefore, a gap 39 exists between the base 33 and the second connecting wall 45. Therefore, each of the first holding member 31 and the second holding member 41 includes a pair of extending arms 36 and a connecting plate portion 35 extending from the pair of extending arms 36 toward the fixed portion 22.

[0047] <Details of the first and second divisions> As shown in FIGS. 1, 7, and 8, in the first segment 20 and the second segment 40, the inner surface 35a of the connecting plate 35 is superimposed on the outer surface 23b of the standing plate 23. That is, the standing plate 23 and the connecting plate 35 are superimposed. The outer surface 23b of the standing plate 23 and the inner surface 35a of the connecting plate 35 face each other and are in contact with each other. Therefore, the connecting plate 35 is superimposed on the outside of the standing plate 23. A connecting bolt 14 is inserted into the through hole 35c of the connecting plate 35. The connecting bolt 14 inserted into the through hole 35c is threaded into the female thread 24 of the standing plate 23. The first segment 20 is formed by connecting the fixing member 21 and the first holding member 31 with the connecting bolt 14 and the female thread 24. Furthermore, the fixing member 21 and the second holding member 41 are connected by the connecting bolt 14 and the female thread 24, thereby forming the second divided body 40.

[0048] Each of the first divided body 20 and the second divided body 40 includes a fixed portion 22 that is fixed to the installation surface F, and a pair of extending arms 36 that extend from the fixed portion 22 and define an arrangement space 37 in which the shaft portion 92 is disposed. Each of the first divided body 20 and the second divided body 40 also includes an erected plate portion 23 that extends from the fixed portion 22 toward the extending arms 36, and a connecting plate portion 35 that extends from the base end side of the pair of extending arms 36 toward the fixed portion 22.

[0049] The first divided body 20 includes a fixing member 21 and a first holding member 31. The second divided body 40 includes a fixing member 21 and a second holding member 41. The fixing member 21 includes a fixing portion 22 and an upright plate portion 23 extending from the fixing portion 22 toward the extending arm portion 36. The adhesive surface 22a, which serves as the lower surface of the fixing portion 22, is provided with an adhesive surface 12a of an adhesive mat 12 that has adhesiveness and can be attached to the installation surface F.

[0050] 1 and 2, in the first segment 20 and the second segment 40, the head 14a of the connecting bolt 14 is disposed on the outer side of the connecting plate 35, which is the one of the upright plate 23 and the connecting plate 35 that is located on the outer side in the direction opposite to the screwing direction of the connecting bolt 14. The pair of extending arms 36 are disposed on the inclined side of the connecting plate 35. The upright plate 23 is overlapped with the connecting plate 35 so as to face the surface of the connecting plate 35 that faces the tip side of the extending arms 36. The upright plate 23 is inclined with respect to the adhesive surface 22a, and the pair of extending arms 36 are disposed on the inclined side of the connecting plate 35.

[0051] Positioning portions are provided on the outer surface 23b of the standing plate portion 23 and the inner surface 35a of the connecting plate portion 35, which restrict movement in a direction perpendicular to the facing direction of the standing plate portion 23 and the connecting plate portion 35 by fitting together recesses and projections. In other words, the positioning portions restrict movement of the standing plate portion 23 along the surface of the connecting plate portion 35 that faces the tip side of the extending arm portion 36 by fitting together recesses and projections. The positioning portions are formed by positioning holes 25 provided in the standing plate portion 23 and protrusions 35d provided on the connecting plate portion 35.

[0052] <Fixed body> As shown in Figures 1, 2, and 6, the stationary body 10 is formed by assembling a first division body 20 and a second division body 40. The first division body 20 and the second division body 40 are assembled such that the extending arms 36 of the first division body 20 and the extending arms 36 of the second division body 40 overlap in the vertical direction Z. More specifically, the pair of extending arms 36 of the second division body 40 are disposed above the pair of extending arms 36 of the first division body 20. The extending arms 36 on one side of the first division body 20 and the second division body 40 overlap in the vertical direction Z, and the extending arms 36 on the other side of the first division body 20 and the second division body 40 overlap in the vertical direction Z.

[0053] The first divided body 20 is one of the two divided bodies, and the second divided body 40 is the other of the two divided bodies. 7 and 8, the first divided body 20 and the second divided body 40 are assembled with the arrangement space 37 of the first divided body 20 and the arrangement space 37 of the second divided body 40 overlapping in the vertical direction Z. The second defining surface 37b of the arrangement space 37 of the first divided body 20 and the second defining surface 37b of the arrangement space 37 of the second divided body 40 face each other in the second direction Y while being offset in the vertical direction Z by the thickness of the extending arm portion 36.

[0054] The second demarcating surface 37b of the first divider 20 closes the opening of the arrangement space 37 of the second divider 40 from the tip side, and the second demarcating surface 37b of the second divider 40 closes the opening of the arrangement space 37 of the first divider 20 from the tip side. Therefore, the first divider 20 and the second divider 40 prevent the shaft portion 92 arranged in the arrangement space 37 from passing through the opening of the arrangement space 37 and coming out of the arrangement space 37. The pair of extending arms 36 sandwich the shaft portion 92 in the first direction X. This first direction X is perpendicular to the second direction Y, which is the arrangement direction of the fixing portion 22.

[0055] Additionally, the first demarcating surfaces 37a of the extending arms 36 that overlap in the vertical direction Z face each other in the first direction X. The pair of extending arms 36 of the first divided body 20 and the pair of extending arms 36 of the second divided body 40 define an enclosed space S that surrounds the shaft portion 92.

[0056] 6, the other extension arm 36 of the extension arm portions 36 provided on the first division body 20 is inserted into the slide groove 44. The other extension arm portion 36 of the second division body 40 is located above the other extension arm portion 36 of the first division body 20, and the lower abutment portion 43b is located below the other extension arm portion 36 of the first division body 20. Therefore, the other extension arm portion 36 of the first division body 20 is sandwiched in the vertical direction Z between the extension arm portion 36 of the second division body 40 and the lower abutment portion 43b.

[0057] The first connecting wall 38 of the first segment 20 and the second connecting wall 45 of the second segment 40 overlap. The second connecting wall 45 overlaps with the first connecting wall 38 so as to cover the outer surface of the first connecting wall 38. The through hole 45a of the second connecting wall 45 overlaps with the threaded portion 38a of the first connecting wall 38. The first connecting wall 38 and the second connecting wall 45 are connected by an assembly bolt 16. The shank 16a of the assembly bolt 16 is inserted into the through hole 45a. The shank 16a of the assembly bolt 16 passes through the through hole 45a and is threaded into the threaded portion 38a. The first segment 20 and the second segment 40 are integrated by the threaded engagement of the shank 16a of the assembly bolt 16 with the threaded portion 38a.

[0058] The direction in which the assembly bolt 16 advances when the assembly bolt 16 is screwed into the screw-in portion 38a is defined as the screw-in direction of the assembly bolt 16. The first connecting wall 38 of the first segment 20 and the second connecting wall 45 of the second segment 40 overlap in the screw-in direction of the assembly bolt 16. Of the first connecting wall 38 and the second connecting wall 45, the first connecting wall 38 located on the far side in the screw-in direction of the assembly bolt 16 is provided with the screw-in portion 38a into which the assembly bolt 16 is screwed. Furthermore, the second connecting wall 45 located on the near side in the screw-in direction of the assembly bolt 16 is provided with a through-hole 45a through which the shank 16a of the assembly bolt 16 passes. The screw-in direction of the assembly bolt 16 is the direction from one of the pair of extending arms 36 to the other extending arm 36.

[0059] <1st assembly section> 1, 2, and 6, the fixed body 10 includes a first assembly portion F1 as an assembly portion. The first assembly portion F1 assembles the extending arm portions 36 on one side that overlap in the vertical direction Z.

[0060] The first assembly part F1 includes an assembly bolt 16 and a threaded portion 38a. The assembly bolt 16 and the threaded portion 38a are assembled so as to restrict the separation in the vertical direction Z of a pair of overlapping extension arm parts 36. Therefore, the first assembly part F1 restricts the separation in the vertical direction Z of the overlapping extension arm parts 36 on one side. The first assembly part F1 is provided on one of the extension arm parts 36 on both sides positioned across the shaft part 92.

[0061] In a state in which the first assembly part F1 restricts the extension arm part 36 from moving apart in the up-down direction Z, the first assembly part F1 itself restricts the relative movement of the first divided body 20 and the second divided body 40 in the direction in which they move apart along the second direction Y. Therefore, the first assembly part F1 is a movement restricting part that restricts the relative movement of the first divided body 20 and the second divided body 40. Therefore, the fixed body 10 has a movement restricting part.

[0062] <Second assembly section> 6 and 7, the fixed body 10 includes a second assembly portion F2 as an assembly portion. The second assembly portion F2 assembles the extending arm portions 36 that overlap in the vertical direction Z with each other.

[0063] The second assembly section F2 includes the extension arm 36 on the other side of the first section 20, and the extension arm 36 and lower abutment portion 43b on the other side of the second section 40. The extension arm 36 on the other side of the first section 20 is inserted into the slide groove 44. That is, of the extension arms 36 provided on the first section 20, the extension arm 36 on the other side is inserted into the slide groove 44. In the second assembly section F2, the extension arm 36 on the other side of the second section 40 is located above the extension arm 36 on the other side of the first section 20, and the lower abutment portion 43b is located below the extension arm 36 on the other side of the first section 20. Therefore, the extension arm 36 on the other side of the first section 20 is sandwiched in the vertical direction Z between the extension arm 36 on the other side of the second section 40 and the lower abutment portion 43b. Therefore, the second assembly portion F2 restricts the separation of the extension arm portions 36 on the other side that overlap in the vertical direction Z in the vertical direction Z. The second assembly portion F2 is provided on the extension arm portion 36 on the other side of the extension arm portions 36 on both sides that are positioned with the shaft portion 92 between them.

[0064] The extension arm 36 and the lower abutment portion 43b on the other side of the second segment 40 limit the relative movement between the first segment 20 and the second segment 40 in the second direction Y when the extension arm 36 is overlapped in the vertical direction Z. In other words, the second assembly portion F2 is an approach / separation guide portion that limits the relative movement between the first segment 20 and the second segment 40 to only the direction in which the second demarcation surfaces 37b, which serve as the base ends of the pair of extension arm portions 36, move toward and away from each other when the extension arm 36 is overlapped in the vertical direction Z. Therefore, the fixed body 10 has an approach / separation guide portion.

[0065] In the second assembly portion F2, the extending arm portion 36 on the other side of the second divided body 40 and the lower contact portion 43b are upper and lower contact portions provided on the extending arm portion 36 of the second divided body 40. In this upper and lower contact portion, the extending arm portion 36 on the other side of the second divided body 40 is the upper contact portion that contacts the upper surface of the extending arm portion 36 on the other side of the first divided body 20. The lower contact portion 43b of the groove forming piece 43 contacts the lower surface of the extending arm portion 36 on the other side of the first divided body 20.

[0066] Of the assembly parts on both sides positioned across the shaft 92, the assembly part provided on the extending arm 36 on one side is the first assembly part F1, and the assembly part provided on the extending arm 36 on the other side is the second assembly part F2. Thus, the fixed body 10 includes assembly parts on each of the extending arms 36 on both sides positioned across the shaft 92 that are assembled so as to restrict separation in the up-down direction Z of the extending arms 36 overlapping in the up-down direction Z.

[0067] <First assembly section and second assembly section> At the first assembly portion F1, the first connecting wall 38 and the second connecting wall 45 extend in the direction in which the extending arm portion 36 extends, and face each other on surfaces extending in that direction. That is, at the first assembly portion F1, the first connecting wall 38 and the second connecting wall 45 face each other across a predetermined width along the direction in which the extending arm portion 36 extends, and the assembly bolt 16 is inserted in this facing state.

[0068] The second assembly part F2 has a groove forming piece 43 that extends in the extension direction of the extending arm part 36 and abuts against the outer surface of the extending arm part 36 of the first segment 20. In other words, the second assembly part F2 is assembled in a state where the extending arm part 36 and the groove forming piece 43 face each other across a predetermined width along the extension direction of the extending arm part 36.

[0069] The first assembly part F1 and the second assembly part F2 are assembled on both sides of the shaft part 92. The vertically overlapping extension arm parts 36 may attempt to rotate about the shaft part 92 while remaining in the overlapped state, so that the directions of extension of the extension arm parts 36 intersect. Even in such a case, the first assembly part F1 and the second assembly part F2 are in surface contact with each other at a predetermined width on both sides of the shaft part 92, thereby restricting the twisting rotation. As a result, the load on the fixing parts 22 of each divided body 20, 40 is reduced, allowing the fixed body 10 to stably hold the installation body 90.

[0070] Furthermore, the first assembly part F1 and the second assembly part F2 integrate the segments 20, 40 so that they do not separate. Therefore, a force acting on one segment is withstood not only by the fixing part 22 of one segment but also by the fixing part 22 of the other segment. As a result, damage to the fixed body 10 can be suppressed compared to a configuration in which the force applied from the installation body 90 is withstood by only one fixing part 22.

[0071] Furthermore, the first assembly part F1 and the second assembly part F2 are located on both sides of the shaft part 92, although they differ in configuration. The first assembly part F1 and the second assembly part F2 not only integrate the first divided body 20 and the second divided body 40, but also function as rotation prevention parts for the two divided bodies 20, 40. Furthermore, the first assembly part F1 and the second assembly part F2 can also be considered as rotation prevention parts that also function as contact and separation guide parts. The first assembly part F1 and the second assembly part F2 are not limited to the embodiment, and may be changed to another configuration that achieves the same purpose.

[0072] <Adjusting the dimensions of the enclosed space S> 8 and 9, the dimension of the enclosed space S in the first direction X is referred to as the first dimension. The first dimension is the dimension between the innermost portion 37c of the first divided body 20 and the innermost portion 37c of the second divided body 40. The dimension of the enclosed space S in the second direction Y is referred to as the second dimension.

[0073] The position where the first divided body 20 and the second divided body 40 are closest to each other in the second direction Y is the first position P1. At the first position P1, the assembly bolt 16 is in contact with the first end 451 of the through hole 45a and is threaded into the threaded portion 38a. At the first position P1, the second dimension is smallest. The second dimension at the first position P1 is the same as or approximately the same as the first width W1. At the first position P1, the fixed body 10 can form a first opposing portion T1 that faces each other at a first distance corresponding to the first width W1.

[0074] Therefore, when the first shaft portion 92A of the first installation body 90A is disposed in the enclosed space S, the second demarcating surface 37b of the first divided body 20 faces the first opposing outer surface 94A of the first shaft portion 92A. Also, the second demarcating surface 37b of the second divided body 40 faces the first opposing outer surface 94A of the first shaft portion 92A. Therefore, the first opposing portion T1 is formed by the second demarcating surface 37b of the first divided body 20 and the second demarcating surface 37b of the second divided body 40.

[0075] The position where the first divided body 20 and the second divided body 40 are furthest apart in the second direction Y is the second position P2. At the second position P2, the assembly bolt 16 is in contact with the second end 452 of the through hole 45a and is threaded into the threaded portion 38a. At the second position P2, the first dimension is at its maximum. The first dimension at the second position P2 is the same as or approximately the same as the second width W2. At the second position P2, the fixed body 10 can form a second opposing portion T2 that faces each other at a second distance corresponding to the second width W2.

[0076] Therefore, when the second shaft portion 92B of the second installation body 90B is arranged in the enclosed space S, a portion of the second demarcating surface 37b of the first division body 20 and the second division body 40 faces the second opposing outer surface 94B of the second shaft portion 92B. Therefore, the second opposing portion T2 is formed by the second demarcating surface 37b of the first division body 20 and the second demarcating surface 37b of the second division body 40.

[0077] In the fixed body 10, the size of the enclosed space S in the first direction X and the size of the enclosed space S in the second direction Y can be adjusted by moving the first divided body 20 and the second divided body 40 relative to each other in the second direction Y. As a result of moving the first divided body 20 and the second divided body 40 relative to each other, the fixed body 10 can take a first position P1 and a second position P2.

[0078] <Method for forming the fixed body and method for holding the shaft> 1 and 5, when the fixed body 10 is formed by the first divided body 20 and the second divided body 40, the tips of the pair of extending arm portions 36 of the first divided body 20 and the second divided body 40 are aligned to face each other in the second direction Y. In addition, release paper is attached to the adhesive surface 12a of the adhesive mat 12.

[0079] The base 93 of the installation body 90 is sandwiched between the fixed portion 22 of the first division body 20 and the fixed portion 22 of the second division body 40 in the second direction Y. Then, with the extending arm portion 36 of the first division body 20 and the extending arm portion 36 of the second division body 40 facing each other, the first division body 20 and the second division body 40 are brought close to each other in the second direction Y. This causes the pair of extending arms 36 of the first division body 20 and the second division body 40 to overlap in the vertical direction Z. In addition, the extending arm portion 36 on the other side of the first division body 20 is inserted into the slide groove 44 of the second division body 40. Note that the lower surface of the extending arm portion 36 on the other side of the second division body 40 and the upper surface of the lower abutment portion 43b guide the relative movement of the first division body 20 and the second division body 40 in the second direction Y.

[0080] The second demarcating surface 37b of the first divided body 20 closes the arrangement space 37 of the second divided body 40 from the tip side, and the second demarcating surface 37b of the second divided body 40 closes the arrangement space 37 of the first divided body 20 from the tip side. As a result, an enclosed space S that surrounds the shaft portion 92 is defined.

[0081] Next, the first connecting wall 38 of the first segment 20 and the second connecting wall 45 of the second segment 40 are connected. The shank 16a of the assembly bolt 16, which has passed through the through hole 45a of the second connecting wall 45, is loosely tightened into the threaded portion 38a of the first connecting wall 38 to establish a provisionally fastened state. The first segment 20 and the second segment 40 are then moved relatively toward and away from each other in the second direction Y. At this time, the relative movement of the first segment 20 and the second segment 40 in the second direction Y is guided by contact between the second connecting wall 45, which forms the through hole 45a, and the assembly bolt 16, and by contact between the groove-forming piece 43 and the extending arm portion 36 on the other side. After adjusting the distance between the first segment 20 and the second segment 40 in the second direction Y, the release paper is peeled off from the adhesive surface 12a, and each fixing portion 22 is fixed to the installation surface F using the adhesive mat 12. Furthermore, the shank 16a of the assembly bolt 16 is tightened into the threaded portion 38a of the first connecting wall 38 to achieve a fully tightened state. This connects the first connecting wall 38 and the second connecting wall 45 together by the assembly bolt 16. After the shank 16a is tightened into the threaded portion 38a to achieve a fully tightened state, the release paper may be peeled off from the adhesive surface 12a, and each fixing portion 22 may be fixed to the installation surface F by the adhesive mat 12. As a result, the first assembly portion F1 is formed, and the second assembly portion F2 is also formed.

[0082] As a result, the fixed body 10 is fixed to the installation surface F, and the shaft portion 92 is held by the fixed body 10. In the case of the first installation body 90A, the fixed body 10 is fixed at a first position P1. The first shaft portion 92A is held by the first opposing portion T1. In the case of the second installation body 90B, the fixed body 10 is fixed at a second position P2. The second shaft portion 92B is held by the second opposing portion T2. ​​The first assembly portion F1 and the second assembly portion F2 restrict the pair of extending arm portions 36 from moving apart in the vertical direction Z.

[0083] <Removing the fixed body> Next, a method for releasing the assembly of the fixed body 10 will be described. For example, when moving the installation body 90, it is necessary to release the support leg 91 from the fixed body 10. At this time, since the fixed member 21 is fixed to the installation surface F, the first holding member 31 and the second holding member 41 are separated from the fixed member 21, and the first holding member 31 and the second holding member 41 are released from holding the shaft portion 92.

[0084] The assembly bolt 16 is removed from the threaded portion 38a and pulled out from the through-hole 45a. The connecting bolt 14 is also removed from the female thread 24 and pulled out from the through-hole 35c.

[0085] 10, the first holding member 31 and the second holding member 41 are moved relatively in the second direction Y so as to move away from each other. At this time, the extension arm 36 on the other side of the first holding member 31 contacts the lower surface of the extension arm 36 on the other side of the second holding member 41 and the upper surface of the lower abutment portion 43b, and is guided in its movement in the second direction Y.

[0086] Then, the connecting plate portion 35 of the first holding member 31 and the connecting plate portion 35 of the second holding member 41 each move away from the standing plate portion 23 of the fixed member 21 in the second direction Y. At this time, the first holding member 31 can move in the second direction Y by utilizing the gap 39 between the first connecting wall 38 and the standing plate portion 23. In addition, the second holding member 41 can move in the second direction Y by utilizing the gap 39 between the second connecting wall 45 and the standing plate portion 23.

[0087] As a result, a gap is formed in the second direction Y between the second demarcation surface 37b of the first retaining member 31 and the shaft portion 92, and a gap is formed in the second direction Y between the second demarcation surface 37b of the second retaining member 41 and the shaft portion 92.

[0088] 11, the tip of the extending arm 36 is lifted while the second connecting wall 45 of the second holding member 41 is brought into contact with the inner surface 23a of the standing plate 23. Then, the second holding member 41 rotates around the contact point between the second connecting wall 45 and the standing plate 23 as a rotation fulcrum, and the shaft 92 at the tip side of the extending arm 36 comes out of the arrangement space 37.

[0089] Similarly, the tip of the extending arm 36 is lifted while the first connecting wall 38 of the first holding member 31 is brought into contact with the inner surface 23a of the standing plate 23. Then, the first holding member 31 rotates around the contact point between the first connecting wall 38 and the standing plate 23 as a rotation fulcrum, and the shaft 92 at the tip side of the extending arm 36 comes out of the arrangement space 37.

[0090] <Operation of the embodiment> When the installation body 90 attempts to move upward due to vibrations such as an earthquake, an upward force is applied to the extension arm 36 from the base 93. The connection between the first connecting wall 38 and the second connecting wall 45 by the assembly bolt 16 and the contact between the extension arm portions 36 on the other side by the upper and lower abutment portions suppresses upward deformation of the extension arm 36. In other words, of the two sides of the shaft portion 92, the first assembly portion F1 suppresses upward deformation on one side, and the second assembly portion F2 suppresses upward deformation on the other side.

[0091] According to the above embodiment, the following effects can be obtained. (1) The fixed body 10 has a first assembly portion F1 on one side of the extension arm 36 and a second assembly portion F2 on the other side of the extension arm 36. The first assembly portion F1 and the second assembly portion F2 are assembled to each other by the extension arms 36 that overlap in the vertical direction Z. Therefore, when the installation body 90 attempts to move upward due to an earthquake or the like, the extension arms 36 that overlap in the vertical direction Z can support the upward force applied from the base 93. Therefore, deformation of both the upper extension arm 36 and the lower extension arm 36 can be suppressed.

[0092] (2) The first segment 20 and the second segment 40 can be fastened together by threading the assembly bolt 16 into the threaded portion 38a, thereby restricting relative movement of the first segment 20 and the second segment 40 in the second direction Y. When the shaft portion 92 moves in the second direction Y through the enclosed space S due to vibrations such as an earthquake, the shaft portion 92 comes into contact with either the first segment 20 or the second segment 40. At this time, the force applied to the segment with which the shaft portion 92 is in contact is also applied to the other segment by the first assembly portion F1. Therefore, the force applied when the shaft portion 92 comes into contact can be distributed and supported by the first segment 20 and the second segment 40, thereby suppressing deformation of the first segment 20 and the second segment 40.

[0093] (3) The fixed body 10 has both a first assembly part F1 and a second assembly part F2. The first assembly part F1 can restrict the relative movement of the first divided body 20 and the second divided body 40 in the second direction Y. Furthermore, when the first assembly part F1 is released, the second assembly part F2 can guide the relative movement of the first divided body 20 and the second divided body 40 in the second direction Y. Therefore, the fixed body 10 is easier to use than when the two assembly parts are only either the first assembly part F1 or the second assembly part F2.

[0094] (4) The fixed body 10 has both the first assembly portion F1 and the second assembly portion F2. Compared to when both assembly portions are the first assembly portion F1, the assembly bolt 16 only needs to be screwed into the screw-in portion 38a once, making the assembly of the fixed body 10 easier.

[0095] (5) Of the assembly parts on both sides of the shaft 92, the assembly part on one side is the first assembly part F1, and the assembly part on the other side is the second assembly part F2. The operation of assembling the first division 20 and the second division 40 with the assembly bolt 16 and the operation of removing the assembly bolt 16 to release the assembly of the fixed body 10 can both be performed using only the extension arm 36 on one side provided with the first assembly part F1. Therefore, the extension arm 36 on the other side provided with the second assembly part F2 does not need to be assembled or released using the assembly bolt 16, making the fixed body 10 easy to use. As a result, even if the gap in the vertical direction Z between the installation body 90 and the installation surface F is narrow, the assembly bolt 16 can be operated using only the extension arm 36 on one side, making it easy to assemble and release the fixed body 10.

[0096] (6) The first connecting wall 38 and the second connecting wall 45 each extend downward from the extending arm portion 36. The first connecting wall 38 is provided with a threaded portion 38a, and the second connecting wall 45 is formed with a through-hole 45a. The first connecting wall 38 and the second connecting wall 45 are overlapped in the first direction X, and the screwing direction of the assembly bolt 16 is the first direction X. Therefore, the first divided body 20 and the second divided body 40 can be assembled by simply screwing the assembly bolt 16 in the first direction X, and the first divided body 20 and the second divided body 40 can be disassembled by simply screwing the assembly bolt 16 back in the first direction X. Therefore, even if the installation body 90 is disposed above the installation surface F, the first divided body 20 and the second divided body 40 can be assembled and disassembled while avoiding interference between the installation body 90 and the assembly bolt 16. Therefore, the installation body 90 can be easily relocated or moved for maintenance.

[0097] (7) The through hole 45a through which the assembly bolt 16 passes is an elongated hole extending in the second direction Y. Furthermore, the dimension of the through hole 45a in the up-down direction Z is greater than the diameter of the shank 16a of the assembly bolt 16. Therefore, as long as the through hole 45a and the threaded portion 38a overlap, the assembly bolt 16 and the through hole 45a can be moved relative to each other when the assembly bolt 16 is temporarily fastened, and therefore the first divided body 20 and the second divided body 40 can be moved relative to each other in the second direction Y. Therefore, the first divided body 20 and the second divided body 40 can be moved relative to each other in accordance with the thickness of the shank 92, and the shank 92 can be held.

[0098] (8) The second assembly part F2 includes the extension arm 36 on the other side of the first divisional body 20, the extension arm 36 on the other side of the second divisional body 40, and the lower abutment part 43b. Specifically, the extension arm 36 on the other side of the first divisional body 20 is inserted into the slide groove 44. Therefore, the second assembly part F2 can restrict the extension arm 36 from moving apart in the vertical direction Z.

[0099] (9) In the second assembly section F2, the extension arm 36 on the other side of the first divided body 20 is inserted into the slide groove 44. The upper surface, lower surface, and one side surface of the extension arm 36 on the other side of the first divided body 20 contact the upper and lower abutment sections. Therefore, when the first divided body 20 and the second divided body 40 are moved relative to each other in the second direction Y, the first divided body 20 and the second divided body 40 can be moved relative to each other only in the second direction Y.

[0100] (10) The first retaining member 31 and the second retaining member 41 are connected to the fixing member 21 by connecting bolts 14. The upright plate portion 23 and the connecting plate portion 35 are overlapped in the second direction Y and connected in the second direction Y by the connecting bolts 14. The connecting plate portion 35 is disposed outward of the upright plate portion 23, and the head 14a of the connecting bolt 14 is disposed on the outer surface 35b of the connecting plate portion 35. Therefore, the head 14a of the connecting bolt 14 can be operated from outside the fixed body 10, making it easy to operate the connecting bolt 14. This makes it easy to separate the first retaining member 31 and the second retaining member 41 from the fixing member 21. Furthermore, because the connecting plate portion 35 is disposed outward of the upright plate portion 23, the retaining members 31, 41 can be separated from the fixing member 21 by moving the retaining members 31, 31 outward of the upright plate portion 23. Therefore, the direction in which the shaft 92 is removed from between the extending arms 36 that sandwich the shaft 92 coincides with the direction in which the holding members 31, 41 are separated from the fixed member 21. Therefore, the removal of the shaft 92 from between the extending arms 36 that sandwich the shaft 92 and the separation of the holding members 31, 41 from the fixed member 21 can be performed simultaneously, which improves the workability of the fixed body 10.

[0101] (11) In the first divided body 20, a gap 39 is formed between the first connecting wall 38 of the first holding member 31 and the standing plate portion 23. In the second divided body 40, a gap 39 is formed between the second connecting wall 45 of the second holding member 41 and the standing plate portion 23. Therefore, the first holding member 31 and the second holding member 41 can move away from the standing plate portion 23 using the gap 39. By moving the first holding member 31 and the second holding member 41 using the gap 39, the first holding member 31 and the second holding member 41 can be rotated around the standing plate portion 23 as a rotation fulcrum. As a result, the shaft portion 92 can pass through the tip end side of each arrangement space 37. Therefore, the first holding member 31 and the second holding member 41 can be separated from each fixing member 21.

[0102] (12) The first division 20 and the second division 40 are formed by integrating the fixing member 21 and the holding members 31, 41. The erected plate portion 23 of the fixing member 21 is inclined with respect to the adhesive surface 22a of the fixing portion 22. Furthermore, the connecting plate portion 35 of each holding member 31, 41 is inclined with respect to the extending arm portion 36. The erected plate portion 23 and the connecting plate portion 35 are connected by the connecting bolt 14. Therefore, each of the first division 20 and the second division 40 has a portion inclined with respect to the shaft portion 92. Therefore, each of the first division 20 and the second division 40 has high strength against a force from the shaft portion 92 in the second direction Y. As a result, there is no need to increase the plate thickness of each of the fixing member 21 and each of the holding members 31, 41 to increase their strength, and therefore the weight of the fixing member 21 and each of the holding members 31, 41 can be reduced.

[0103] (13) The fixed body 10 can form a first opposing portion T1 at the first position P1 and a second opposing portion T2 at the second position P2. At the first position P1, the first opposing portion T1 can hold the first shaft portion 92A by bringing the second demarcating surface 37b into contact with the first opposing outer surface 94A. At the second position P2, the second opposing portion T2 can hold the second shaft portion 92B by bringing the second demarcating surface 37b into contact with the second opposing outer surface 94B. Therefore, at both the first position P1 and the second position P2, contact with the shaft portion 92 can be maintained, improving the function of suppressing movement due to external shocks such as vibrations or collisions, or shaking caused by earthquakes.

[0104] (14) By moving the first divided body 20 and the second divided body 40 relative to each other in the second direction Y, the fixed body 10 can be switched between the first position P1 and the second position P2. Therefore, by moving the first divided body 20 and the second divided body 40 relative to each other in the second direction Y, the opposing portion that holds the shaft portion 92 can be switched between the first opposing portion T1 and the second opposing portion T2. ​​Therefore, switching between the first opposing portion T1 and the second opposing portion T2 can be easily performed.

[0105] (15) Each of the first and second segments 20 and 40 has a positioning portion formed by the engagement of the positioning hole 25 with the protrusion 35d. The engagement of the recesses and projections of the positioning hole 25 with the protrusion 35d restricts movement of each holding member 31, 41 along the outer surface 23b of the standing plate portion 23 and the inner surface 35a of the connecting plate portion 35. This facilitates alignment of the female thread 24 of the standing plate portion 23 with the through hole 35c of the connecting plate portion 35. This facilitates the work of connecting the standing plate portion 23 and the connecting plate portion 35 with the connecting bolt 14. Furthermore, the engagement of the recesses and projections of the positioning hole 25 with the protrusion 35d prevents misalignment of the standing plate portion 23 and the connecting plate portion 35 along the surface direction due to impacts such as earthquakes. Therefore, it is possible to prevent a force acting on the connecting bolt 14 that would shear the connecting bolt 14 due to misalignment between the standing plate portion 23 and the connecting plate portion 35 in the planar direction.

[0106] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. A hole penetrating in the plate thickness direction is formed in each of the extending arm portion 36 on the other side of the first segment 20 and the extending arm portion 36 on the other side of the second segment 40. A threaded portion into which the assembly bolt 16 is threaded is formed in the lower abutting portion 43b of the groove forming piece 43. The extending arm portions 36 on the other side that overlap in the vertical direction Z may then be assembled together with the assembly bolt 16. In this case, both the first assembly portion F1 and the second assembly portion F2 are provided on the extending arm portion 36 on the other side.

[0107] The through hole 45a may be a circular hole through which the shank 16a of the assembly bolt 16 can be inserted. In this case, only one type of shank 92 can be held in the enclosed space S. Therefore, two types of fixed bodies 10 are manufactured by adjusting the position of the through hole 45a in the second connecting wall 45 in the second direction Y so that the first shank 92A or the second shank 92B can be held by the fixed body 10.

[0108] Alternatively, a plurality of through holes 45a may be formed in the second connecting wall 45 to hold a plurality of types of shaft portions 92. In this case, it is preferable that the plurality of through holes 45a be arranged in parallel in the direction in which the extending arm portion 36 extends.

[0109] The positioning holes 25 of the standing plate portions 23 and the protrusions 35d of the connecting plate portions 35 may be omitted. The positioning portion may have a configuration other than the positioning hole 25 and the protrusion 35d. For example, the positioning portion may be composed of a protrusion protruding from each of the short sides of the connecting plate portion 35 in the extension direction of the extending arm portion 36 and an end surface along the short sides of the standing plate portion 23. Even in this case, relative movement between the fixing member 21 and each holding member 31, 41 along the extension direction of the extending arm portion 36 is permitted, while relative movement between the fixing member 21 and each holding member 31, 41 along the long side of the connecting plate portion 35 is restricted. Furthermore, the female thread 24 of the standing plate portion 23 can be aligned with the through hole 35c of the connecting plate portion 35 in the short side direction of the connecting plate portion 35. In this case, the protrusion from the connecting plate portion 35 functions as the protrusion of the positioning portion, and the end surfaces along the short sides of the standing plate portion 23 function as the positioning hole of the positioning portion.

[0110] The positioning hole 25 of the standing plate portion 23 and the convex portion 35d of the connecting plate portion 35 may be fitted together only at both ends of the long side of the positioning hole 25, thereby restricting movement of the positioning hole 25 only in the long side direction. Alternatively, the positioning hole 25 of the standing plate portion 23 and the convex portion 35d of the connecting plate portion 35 may be fitted together only at both ends of the short side of the positioning hole 25, thereby restricting movement of the positioning hole 25 only in the short side direction.

[0111] In the fixing member 21, the fixing portion 22 and the standing plate portion 23 may be perpendicular to each other. In this case, in each holding member 31, 41, the base portion 33 and the connecting plate portion 35 are perpendicular to each other. In each divided body 20, 40, the extending direction of the pair of extending arm portions 36 is perpendicular to the erecting direction of the standing plate portion 23. Note that in only one of the first divided body 20 and the second divided body 40, the fixing portion 22 and the standing plate portion 23 may be perpendicular to each other, and in the holding member, the base portion 33 and the connecting plate portion 35 may be perpendicular to each other.

[0112] The first divided body 20 may be formed by welding the fixing member 21 and the first holding member 31, and the second divided body 40 may be formed by welding the fixing member 21 and the second holding member 41. The first divided body 20 and the second divided body 40 may be formed from a single plate.

[0113] In the first divided body 20, the female thread 24 may be a through hole. The fixing member 21 and the first holding member 31 may be connected by threading a nut onto the through hole 35c and the connecting bolt 14 that passes through the through hole. Similarly, in the second divided body 40, the female thread 24 may be a through hole. The fixing member 21 and the second holding member 41 may be connected by threading a nut onto the connecting bolt 14 that passes through the through hole 35c and the through hole.

[0114] The groove-forming piece 43 of the second holding member 41 may be omitted. In this case, a ring-shaped member is provided as an upper and lower abutment portion at the base end of the extension arm 36 on the other side of the second holding member 41, into which the tip of the extension arm 36 on the other side of the first division 20 can be inserted. In this configuration, the first division 20 and the second division 40 are moved relative to each other in the second direction Y to bring the first division 20 and the second division 40 closer together. The tip of the extension arm 36 on the other side of the second holding member 41 is inserted into the upper and lower abutment portion. Then, the upper surface of the extension arm 36 on the other side of the first division 20 abuts against the lower surface of the extension arm 36 on the other side of the second division 40, and the lower surface of the extension arm 36 on the other side of the first division 20 abuts against the upper surface of the lower abutment portion of the upper and lower abutment portion. In this configuration, the dimension of the slide groove 44 in the second direction Y is smaller than in the embodiment.

[0115] A through-hole may be provided in the first connecting wall 38 of the first division 20, and a threaded portion may be provided in the second connecting wall 45 of the second division 40. The assembly bolt 16 may then be threaded from the first connecting wall 38 side of the first division 20 into the second connecting wall 45 of the second division 40.

[0116] Of the extension arms 36 located on both sides of the shaft 92, the extension arm 36 on one side may be provided with a first assembly portion F1, and the extension arm 36 on the other side may also be provided with a first assembly portion F1. Alternatively, of the extension arms 36 located on both sides of the shaft 92, the extension arm 36 on one side may be provided with a second assembly portion F2, and the extension arm 36 on the other side may also be provided with a second assembly portion F2. In this case, the fixed body 10 does not have a movement restricting portion.

[0117] Of the extension arms 36 located on both sides of the shaft 92, the extension arm 36 on one side may be provided with the second attachment portion F2, and the extension arm 36 on the other side may be provided with the first attachment portion F1. [Explanation of symbols]
