[0016] 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 placed on the fixed surface F to the fixed surface F. The fixed body 10 prevents the installation body 90 from moving due to an earthquake. The fixed surface F is the floor surface. However, the fixed surface F may be changed as appropriate as long as it is a surface to which the installation body 90 can be fixed.

[0017] <Installation object> 1, 2, and 6, the installation body 90 may be any type of device, such as a home TV stand, an office copy machine, or a shelf. The direction perpendicular to the fixed surface F is defined as the up-down direction Z. Therefore, the up-down direction Z is a vertical direction.

[0018] The installation body 90 includes a support leg 91. The support leg 91 includes a base 93 that is placed on the fixed 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 threaded onto 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 fixed 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.

[0019] As shown in FIGS. 1, 3 and 5, the stationary body 10 is formed by assembling a first divided body 20 and a second divided body 40 together. <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.

[0020] 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 plate-shaped fixing portion 22 and a plate-shaped standing plate portion 23. The fixing portion 22 and the standing plate portion 23 are integral. The fixing members 21 are 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 recess 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.

[0021] The fixing portion 22 is fixed to a fixing surface F. The fixing portion 22 has a rectangular plate shape. When the fixing portion 22 is viewed in the plate thickness direction, the direction in which the long sides of the fixing portion 22 extend is defined as a first direction X, and the direction in which the short sides of the fixing portion 22 extend is defined as a second direction Y.

[0022] The fixing part 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. The adhesive mat 12 is made of a gel-like, ultra-soft urethane with adhesive properties. The adhesive mat 12 is compressible and deformable in the thickness direction. 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 part 22. The other adhesive surface 12a of the adhesive mat 12 is attached to the fixed surface F. When the fixing body 10 is not in use, a release paper (not shown) is attached to the other adhesive surface 12a of the adhesive mat 12. Therefore, the fixing part 22 has an adhesive surface 22a to which the adhesive mat 12, which is to be attached to the surface F to be fixed, is attached.

[0023] When fixing the fixing body 10 to the fixing surface F, the release paper is peeled off from the other adhesive surface 12a, and the fixing portion 22 is fixed to the fixing surface F by the adhesive mat 12. By fixing the fixing portion 22 to the fixing surface F by the adhesive mat 12, the first divided body 20 and the second divided body 40 are fixed to the fixing surface F.

[0024] The standing plate portion 23 is in the shape of a rectangular plate extending along one long side of the fixed portion 22 . As shown in FIG. 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 are each rectangular. The inner surface 23a is a surface that continues with the adhesive surface 22a of the fixing portion 22. The outer surface 23b is a surface that continues with 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 adhesive surface 22a and the inner surface 23a intersect, and the opposite surface 22b and the outer surface 23b intersect. Therefore, the standing plate portion 23 stands upright from the fixing portion 22 so as to be away from the adhesive surface 22a.

[0025] In a side view of the fixing member 21, the angle formed between the fixing portion 22 and the standing plate portion 23, that formed between the opposite surface 22b and the outer surface 23b, is an obtuse angle. The standing plate portion 23 is erected 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 so as to form an obtuse angle 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.

[0026] 3, female screws 24 are formed as through-holes 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. 8 and 9, a recess 25 is formed in the center of the standing plate portion 23 in the first direction X. The recess 25 penetrates the standing plate portion 23 in the plate thickness direction. When the standing plate portion 23 is viewed from the inner surface 23a, the recess 25 has a rectangular shape with its long sides extending in the direction of the short sides of the standing plate portion 23.

[0027] The standing plate portion 23 has a recess-forming surface 26 that defines the recess 25. The recess-forming surface 26 has a first recess-forming surface 26a and a second recess-forming surface 26b that face each other in the up-down direction Z, and a third recess-forming surface 26c and a fourth recess-forming surface 26d that face each other in the first direction X. The recess-forming surface 26 is a flat surface whose long side extends in a direction perpendicular to the inner surface 23a and the outer surface 23b.

[0028] The shortest distance between the first recess-forming surface 26a and the second recess-forming surface 26b is defined as a first dimension N1 of the recess 25. The shortest distance between the third recess-forming surface 26c and the fourth recess-forming surface 26d is defined as a second dimension N2 of the recess 25. The first dimension N1 and the second dimension N2 are each constant in the thickness direction of the standing plate portion 23.

[0029] The dimension of the upright plate portion 23 in the plate thickness direction is the depth D of the recess 25. The depth D of the recess 25 is the dimension of a recess forming surface 26 that connects the inner surface 23a and the outer surface 23b of the upright plate portion 23. <First holding member and second holding member> 3, 4, and 5, the first holding member 31 includes a base 33, a pair of extending arms 36 serving as holding portions, and a connecting plate 35. The pair of extending arms 36 include first connecting walls 38 serving as protrusions.

[0030] The second holding member 41 includes a base 33, a pair of extending arms 36 as holding portions, and a connecting plate portion 35. The pair of extending arms 36 include groove-forming pieces 43 as protrusions and a second connecting wall 45. In the first holding member 31 and the second holding member 41, the pair of extending arms 36 are located on both sides of the arrangement space 37. One side of the extending arms 36 located on both sides of the arrangement space 37 is referred to as the one-side extending arm 36, and the other is referred to as the other-side extending arm 36.

[0031] 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 than the center in the short side direction of the rectangular metal plate. The connecting plate portion 35 has the same configuration in the first holding member 31 and the second holding member 41, except that the dimensions are different.

[0032] 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.

[0033] The pair of extending arms 36 extend from one of a pair of long sides of the base 33. The pair of extending arms 36 extend from the center of the base 33 in the first direction X. The direction in which the extending arms 36 extend from the base 33 coincides with the second direction Y. The base end of the extending arm 36 is the end closer to the base 33 in the second direction Y, and the tip of the extending arm 36 is the end opposite the base 33 in the second direction Y. The pair of extending 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 extending arms 36 in the first direction X.

[0034] 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 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 arms 36. The arrangement space 37 is defined between the pair of extending arms 36 so that the shaft portion 92 can be received from the tip side of the extending arm portion 36 toward the base end.

[0035] 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.

[0036] The distance between the pair of first defining surfaces 37a in the first direction X is greater than the width of the shaft portion 92. Therefore, the shaft portion 92 of the support leg 91 can be inserted into the arrangement space 37 from the tip side of the extending arm portion 36, that is, from the opening side of the arrangement space 37.

[0037] 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, which includes the innermost portion 37c, is the base end of the arrangement space 37. When the shaft portion 92 is brought into contact with the innermost portion 37c, the shaft portion 92 is held by the fixed body 10. Then, the shaft portion 92 arranged in the arrangement space 37 is held by the pair of extension arms 36, and therefore the installation body 90 is held by the pair of extension arms 36.

[0038] 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. The connecting plate portion 35 is overlapped with the standing plate portion 23 of the fixing member 21. Therefore, each of the first holding member 31 and the second holding member 41 includes a pair of extending arms 36 that hold the installation body 90, and a connecting plate portion 35 that overlaps with the erected plate portion 23.

[0039] 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. The first holding member 31 and the second holding member 41 have a protrusion 15 in the center of the connecting plate portion 35 in the first direction X. The protrusion 15 protrudes from the inner surface 35a of the connecting plate portion 35.

[0040] 8 and 9, when the connecting plate portion 35 is viewed from the inner surface 35a, the protrusion 15 has a rectangular plate shape with its long sides extending in the direction of the short sides of the connecting plate portion 35. The protrusion 15 is fitted into the recess 25 of the standing plate portion 23.

[0041] The protrusion 15 has a tip surface 15a. The tip surface 15a is located at the tip of the protrusion 15 in the direction in which the protrusion 15 protrudes from the inner surface 35a of the connecting plate 35. The dimension of the protrusion 15 from the inner surface 35a of the connecting plate 35 to the tip surface 15a is defined as a protrusion length G. The protrusion length G of the protrusion 15 is smaller than the depth D of the recess 25.

[0042] The protrusion 15 has a protrusion-forming surface 17 that defines the four side surfaces of the protrusion 15. The protrusion-forming surface 17 has a first protrusion-forming surface 17a and a second protrusion-forming surface 17b that face each other in the vertical direction Z, and a third protrusion-forming surface 17c and a fourth protrusion-forming surface 17d that face each other in the first direction X. Each of the first protrusion-forming surface 17a and the second protrusion-forming surface 17b includes an arc-shaped surface 18 on the side of the tip surface 15a of the protrusion 15. The tip surface 15a of the protrusion 15 is formed between a pair of arc-shaped surfaces 18 in the vertical direction Z.

[0043] The distance between the first convex portion forming surface 17a and the second convex portion forming surface 17b is defined as the first dimension M1 of the convex portion 15. The first dimension M1 of the convex portion 15 gradually decreases from the base end of the convex portion 15 to the tip end thereof due to the pair of arcuate surfaces 18. The first dimension M1 is maximum except at the arcuate surfaces 18 and is minimum at the tip end surface 15a. The first dimension M1 of the convex portion 15 is smaller than the first dimension N1 of the recess 25.

[0044] The distance between the third convex portion forming surface 17c and the fourth convex portion forming surface 17d is defined as the second dimension M2 of the convex portion 15. The second dimension M2 of the convex portion 15 is the dimension of the convex portion 15 in the first direction X. The second dimension M2 of the convex portion 15 is slightly smaller than the second dimension N2 of the concave portion 25.

[0045] 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.

[0046] Next, the first holding member 31 will be described. 3 and 4, the first connecting wall 38 serving as a protrusion extends from one of the pair of extending arm portions 36. The first connecting wall 38 extends in the thickness direction of the extending arm portion 36. The first connecting wall 38 extends downward from the one extending arm portion 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.

[0047] 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.

[0048] As shown in FIGS. 3 and 5, the groove-forming piece 43 serving as a protrusion extends from the other of the pair of extending arms 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 36. The extending piece 43a extends downward from the other extending arm 36. The lower abutting portion 43b extends from the lower end of the extending piece 43a toward the one extending arm 36. The lower abutting portion 43b is spaced apart from the other extending arm 36 in the up-down direction Z. A slide groove 44 is defined between the other extending arm 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.

[0049] The second connecting wall 45 serving as a protrusion 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 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 second connecting wall 45 is spaced apart from the base portion 33 in the second direction Y. Therefore, a gap 39 exists between the base portion 33 and the second connecting wall 45.

[0050] <Details of the first and second divisions> First, a description will be given of a manufacturing method for the first divided body 20 and the second divided body 40. Since the manufacturing methods for the first divided body 20 and the second divided body 40 are the same, the description will be focused on the manufacturing method for the first divided body 20, and a description of the manufacturing method for the second divided body 40 will be omitted.

[0051] 11 , the connecting plate portion 35 is placed outside the outer surface 23b of the standing plate portion 23. The connecting plate portion 35 of the first holding member 31 is made to face the standing plate portion 23 of the fixed member 21, and the connecting plate portion 35 of the second holding member 41 is made to face the standing plate portion 23 of the fixed member 21. Specifically, the inner surface 35a of the connecting plate portion 35 is made to face the outer surface 23b of the standing plate portion 23.

[0052] The first connecting wall 38 of the first holding member 31 is separated from the standing plate portion 23 in the second direction Y by the gap 39. At this time, the first connecting wall 38 is separated from the standing plate portion 23 in the second direction Y by the gap 39. Therefore, by utilizing the gap 39, the connecting plate portion 35 and the standing plate portion 23 can be made to face each other without the convex portion 15 entering the concave portion 25. Therefore, the first connecting wall 38 is separated from the standing plate portion 23 so as to form the gap 39 that allows the connecting plate portion 35 and the standing plate portion 23 to face each other without the convex portion 15 entering the concave portion 25.

[0053] Furthermore, each of the groove forming pieces 43 and the second connecting wall 45 of the second holding member 41 is spaced apart from the standing plate portion 23 in the second direction Y by the gap 39. At this time, each of the groove forming pieces 43 and the second connecting wall 45 is spaced apart from the standing plate portion 23 in the second direction Y by the gap 39. Therefore, by utilizing the gap 39, the connecting plate portion 35 and the standing plate portion 23 can be made to face each other without the convex portion 15 entering the concave portion 25. Therefore, each of the groove forming pieces 43 and the second connecting wall 45 is spaced apart from the standing plate portion 23 to form the gap 39 that allows the connecting plate portion 35 and the standing plate portion 23 to face each other without the convex portion 15 entering the concave portion 25.

[0054] Next, the holding members 31, 41 and the standing plate portion 23 are moved relatively in the second direction Y to approach each other. Then, as shown in Figures 8 and 9, the convex portion 15 of the connecting plate portion 35 is fitted into the concave portion 25 of the standing plate portion 23. Then, as shown in Figure 2, the fitting of the concave portion 25 and the convex portion 15 causes the through hole 35c of the connecting plate portion 35 to align with the female thread 24 of the standing plate portion 23.

[0055] At this time, the first convex portion forming surface 17a and the first recess portion forming surface 26a are in contact with each other, while a gap is formed between the second convex portion forming surface 17b and the second recess portion forming surface 26b. Therefore, the fitting of the convex portion 15 and the recess portion 25 restricts the upward movement of each of the holding members 31, 41 in the direction along the outer surface 23b of the standing plate portion 23 and the inner surface 35a of the connecting plate portion 35.

[0056] Furthermore, the third convex portion forming surface 17c contacts the third recess portion forming surface 26c, and the fourth convex portion forming surface 17d contacts the fourth recess portion forming surface 26d. Therefore, the engagement between the convex portion 15 and the recess portion 25 restricts movement of each holding member 31, 41 in the first direction X, among directions along the outer surface 23b of the standing plate portion 23 and the inner surface 35a of the connecting plate portion 35. Therefore, the engagement between the convex portion 15 and the recess portion 25 restricts movement of each holding member 31, 41 in all directions except downward.

[0057] 2, the connecting bolt 14 is inserted into the through hole 35c of the connecting plate portion 35, and the connecting bolt 14 that has passed through the through hole 35c is screwed into the female thread 24 of the standing plate portion 23. As a result, the connecting plate portion 35 and the standing plate portion 23 are connected by the connecting bolt 14. Therefore, the connecting plate portion 35 has the through hole 35c through which the connecting bolt 14 passes, and the standing plate portion 23 has the female thread 24 through which the connecting bolt 14 passes.

[0058] The direction from the connecting plate portion 35 toward the standing plate portion 23 is the screw-in direction of the connecting bolt 14. Therefore, the connecting plate portion 35 is overlapped with the standing plate portion 23 on the side opposite to the screw-in direction of the connecting bolt 14 from the standing plate portion 23.

[0059] The first divided body 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. Similarly, the second divided body 40 is formed by connecting the fixing member 21 and the second holding member 41 with the connecting bolt 14.

[0060] Next, the first divided body 20 and the second divided body 40 will be described in detail. 1, 6, and 7, in the first divided body 20 and the second divided body 40, the inner surface 35a of the connecting plate portion 35 overlaps with the outer surface 23b of the standing plate portion 23. The connecting plate portion 35 and the standing plate portion 23 overlap in their respective thickness directions. Therefore, the overlap direction of the connecting plate portion 35 and the standing plate portion 23 is the respective thickness directions.

[0061] The outer surface 23b of the standing plate portion 23 and the inner surface 35a of the connecting plate portion 35 face each other and are in contact with each other. Therefore, the outer surface 23b of the standing plate portion 23 and the inner surface 35a of the connecting plate portion 35 are opposing surfaces that face each other. A recess 25 is provided on the outer surface 23b, which is one of the opposing surfaces, and a protrusion 15 is provided on the inner surface 35a, which is the other opposing surface.

[0062] The outer surface 23b of the standing plate portion 23 is inclined to form an obtuse angle with the adhering surface 22a, so that the pair of extending arms 36 are disposed on the inclined side of the standing plate portion 23.

[0063] In the first divided body 20, the first connecting wall 38 of the first holding member 31 protrudes toward the fixed surface F beyond the tip of the erected plate portion 23 of the fixing member 21. In addition, in the second divided body 40, the groove forming piece 43 and the second connecting wall 45 of the second holding member 41 each protrude toward the fixed surface F beyond the tip of the erected plate portion 23 of the fixing member 21.

[0064] <Concave and convex parts> 8 and 9, the depth D of the recess 25 is greater than the protruding length G of the protrusion 15. Therefore, when the connecting plate 35 and the standing plate 23 are connected by the connecting bolt 14, the recess-forming surface 26 is exposed beyond the tip surface 15a of the protrusion 15.

[0065] Furthermore, when the protrusion 15 is fitted into the recess 25, an overlapping portion is formed where the protrusion 15 and the recess 25 overlap in the vertical direction Z. The overlapping portion is formed by a first protrusion-forming surface 17a as a holding-member-side overlapping surface provided on each of the holding members 31 and 41, and a first recess-forming surface 26a as a fixing-member-side overlapping surface provided on the fixing member 21.

[0066] In the overlapping portion, the first convex portion forming surface 17a has a holding member side end portion 171. The holding member side end portion 171 is an end portion of the first convex portion forming surface 17a in the overlapping direction that is located on the side of the shaft portion 92 held by the extending arm portion 36.

[0067] In the overlapping portion, the first recess-forming surface 26a has a fixing member-side end portion 261. The fixing member-side end portion 261 is one of both ends of the first recess-forming surface 26a in the overlapping direction, and is the end portion opposite the shaft portion 92 held by the extending arm portion 36.

[0068] When the connecting plate portion 35 and the standing plate portion 23 are connected by the connecting bolt 14, the holding member side end portion 171 and the fixing member side end portion 261 are located at opposite ends in the overlapping direction. The holding member side end portion 171 is located closer to the shaft portion 92 than the fixing member side end portion 261.

[0069] <Fixed body> As shown in Figures 1, 2, and 6, the fixed 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 by overlapping the extending arm portion 36 of the first division body 20 and the extending arm portion 36 of the second division body 40 in the vertical direction Z. More specifically, the pair of extending arm portions 36 of the second division body 40 are disposed above the pair of extending arm portions 36 of the first division body 20. The extending arm portions 36 on one side of the first division body 20 and the second division body 40 are overlapped in the vertical direction Z, and the extending arm portions 36 on the other side of the first division body 20 and the second division body 40 are overlapped in the vertical direction Z.

[0070] 6 and 7, the first division body 20 and the second division body 40 are assembled with the arrangement space 37 of the first division body 20 and the arrangement space 37 of the second division body 40 overlapping in the vertical direction Z. The second defining surface 37b of the arrangement space 37 of the first division body 20 and the second defining surface 37b of the arrangement space 37 of the second division 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.

[0071] 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 from both sides 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] <Method of forming the fixed body> 11, 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.

[0077] The base 93 of the installation body 90 is sandwiched in the second direction Y between the fixed portion 22 of the first division body 20 and the fixed portion 22 of the second division body 40. Then, from a state in which the extending arm portion 36 of the first division body 20 and the extending arm portion 36 of the second division body 40 face each other, the first division body 20 and the second division body 40 are brought close to each other in the second direction Y.

[0078] 7, the pair of extending arms 36 of the first and second divisional bodies 20 and 40 are overlapped in the vertical direction Z. The extending arm 36 on the other side of the first divisional body 20 is inserted into the slide groove 44 of the second divisional body 40. The lower surface of the extending arm 36 on the other side of the second divisional body 40 and the upper surface of the lower abutment portion 43b guide the relative movement of the first divisional body 20 and the second divisional body 40 in the second direction Y.

[0079] 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.

[0080] 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 fixing 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 fixing surface F by the adhesive mat 12. As a result, the fixing body 10 is fixed to the fixing surface F, and the shank 92 is held by the fixing body 10.

[0081] <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 fixed 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.

[0082] First, the assembly bolt 16 is removed from the threaded portion 38a and pulled out from the through-hole 45a. Then, the connecting bolt 14 is removed from the female thread 24 and pulled out from the through-hole 35c.

[0083] Next, the first holding member 31 and the second holding member 41 are separated from the fixing member 21. There are two methods for separating the holding members 31, 41 from the fixing member 21. In a first method for separating the holding members 31, 41 from the fixed member 21, first, the first holding member 31 and the second holding member 41 are each moved upward, as shown in Fig. 10. In this case, "upward" refers to a direction in which the holding members 31, 41 are moved away from the fixed member 21 from the state in which the convex portion 15 and the concave portion 25 are fitted together, and is a direction perpendicular to the fixed surface F.

[0084] When each holding member 31, 41 is moved upward, the arcuate surface 18 of the first convex portion-forming surface 17a slides against the first recess-forming surface 26a. The arcuate surface 18 is shaped to bulge from the distal end surface 15a of the convex portion 15 toward the proximal end. Therefore, compared to, for example, when the arcuate surface 18 is not formed on the first convex portion-forming surface 17a, i.e., when the distal end of the convex portion 15 is a pin-angled angle, interference between the convex portion-forming surface 17 and the recess-forming surface 26 is avoided. Therefore, the arcuate surface 18 is an interference avoidance means that allows each holding member 31, 41 to move upward. Therefore, the fixed body 10 is equipped with an interference avoidance means.

[0085] When the arc-shaped surface 18 slides against the first recess-forming surface 26a, the standing plate portion 23 is pressed upward by the arc-shaped surface 18. This pressing force displaces the standing plate portion 23 so that the inner surface 23a faces the base 93. As a result, the fixing member 21 tilts such that the inner surface 23a of the standing plate portion 23 faces downward and the opposite surface 22b of the fixing portion 22 faces upward, with the intersection of the standing plate portion 23 and the fixing portion 22 as the boundary. Therefore, when the holding members 31, 41 are moved upward away from the fixing member 21, the arc-shaped surface 18 tilts the fixing member 21 so that the standing angle of the standing plate portion 23 changes.

[0086] As a result, the closer the adhesive surface 22a of the fixing portion 22 is to the standing plate portion 23 in the second direction Y, the closer it is to the fixed surface F. At this time, since the adhesive mat 12 is made of a compressible material, the adhesive mat 12 is compressed between the adhesive surface 22a and the fixed surface F. As a result, the first holding member 31 and the second holding member 41 can move upward. In other words, the tilting of the fixing member 21 changes the relative positions of the fixing member 21 and the holding members 31 and 41.

[0087] Then, when the first holding member 31 and the second holding member 41 are moved upward relative to the fixing member 21 so as to move away from the fixing surface F, the first convex portion-forming surface 17a moves upward to pass over the first recess-forming surface 26a of the recess 25. That is, in the vertical direction Z, of the first convex portion-forming surface 17a and the first recess-forming surface 26a that overlap in the vertical direction Z, the first convex portion-forming surface 17a on the fixing surface F side can move over the first recess-forming surface 26a on the opposite side to the fixing surface F. As a result, the engagement between the convex portion 15 and the recess 25 is released, and the fixing member 21 is separated from each holding member 31, 41.

[0088] Therefore, if the tip of the convex portion 15 is a pin angle, when an attempt is made to move each of the holding members 31, 41 upward, the first convex portion forming surface 17a interferes with the first concave portion forming surface 26a, and the fixing member 21 does not tilt. As a result, the relative positions of each of the holding members 31, 41 and the fixing member 21 cannot be changed, and therefore each of the holding members 31, 41 and the fixing member 21 cannot be separated.

[0089] If the arcuate surface 18 is formed on the convex portion forming surface 17, the arcuate surface 18 can be slid against the first recess forming surface 26a when the holding members 31, 41 are moved upward. In this case, for example, even if the adhesive mat 12 cannot be compressed and deformed, the relative positions of the holding members 31, 41 and the fixing member 21 can be changed by forcibly deforming the standing plate portion 23. As a result, the holding members 31, 41 and the fixing member 21 can be separated while reducing the sliding resistance between the arcuate surface 18 and the first recess forming surface 26a.

[0090] The first method for separating the holding members 31, 41 from the fixing member 21 is preferably used when it is difficult to move the holding members 31, 41 horizontally. In this case, the holding members 31, 41 are moved upward. As a result, the arc-shaped surfaces 18 slide against the recess-forming surfaces 26, the holding members 31, 41 move upward, and the protrusions 15 move slightly out of the recesses 25. Thereafter, the holding members 31, 41 are moved horizontally. At this time, the arc-shaped surfaces 18 make it easier for the holding members 31, 41 to move horizontally, allowing the holding members 31, 41 to be smoothly separated from the fixing member 21.

[0091] 11, the second method for separating the holding members 31, 41 from the fixed member 21 involves moving the first holding member 31 and the second holding member 41 in the second direction Y relative to the fixed member 21 so as to move them away from each other. The second direction Y is a direction in which the holding members 31, 41 are parallel to the fixed surface F with respect to the fixed member 21, and a direction away from the installation body 90 held by the extending arm portion 36.

[0092] When each holding member 31, 41 is moved in the second direction Y away from the fixed member 21, the extension arm 36 on the other side of the first holding member 31 comes into contact with 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. In other words, the extension arm 36 on the other side of the first holding member 31 is guided in its movement in the second direction Y by the surface that defines the slide groove 44.

[0093] At this time, each of the first holding member 31 and the second holding member 41 can move such that the holding member side end 171 exceeds the fixed member side end 261. Therefore, each of the first holding member 31 and the second holding member 41 moves such that the convex portion 15 comes out of the concave portion 25.

[0094] 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 fixing 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. Also, 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 groove forming piece 43 and the standing plate portion 23.

[0095] 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.

[0096] 12, 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 groove forming piece 43 and the standing plate 23 as the rotation fulcrum, and the shaft 92 at the tip side of the extending arm 36 comes out of the arrangement space 37.

[0097] 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.

[0098] As a result, each of the first holding member 31 and the second holding member 41 can be separated from the fixing member 21. Thereafter, the installation body 90 can be moved along the surface F to be fixed.

[0099] The method of separating each of the first holding member 31 and the second holding member 41 from the fixing member 21 may be a combination of the above two methods rather than being performed separately. 11, after moving each of the holding members 31, 41 in the horizontal direction, as shown in FIG. 12, the holding members 31, 41 do not have to be rotated. That is, each of the holding members 31, 41 may be separated from the fixed member 21 by continuing to move each of the holding members 31, 41 away from the fixed member 21 in the second direction Y. In this configuration, each of the holding members 31, 41 can be separated from the fixed member 21 even if there is no space above each of the holding members 31, 41 of the fixed body 10 to rotate each of the holding members 31, 41. In this case, each of the holding members 31, 41 may be moved in the first direction X after the protrusion 15 is removed from the recess 25. To enable the movement of each of the holding members 31, 41 in the first direction X, the shaft portion 92 needs to be removed from the arrangement space 37, so the dimension of the gap 39 in the second direction Y is increased.

[0100] According to the above embodiment, the following effects can be obtained. (1) Each of the holding members 31, 41 has a protrusion 15, and the fixing member 21 has a recess 25. When the protrusion 15 and the recess 25 are fitted together, the female thread 24 of the standing plate portion 23 and the through hole 35c of the connecting plate portion 35 can be aligned. Therefore, when connecting each of the holding members 31, 41 and the fixing member 21, the female thread 24 and the through hole 35c can be easily aligned. As a result, the operation of connecting each of the holding members 31, 41 and the fixing member 21 with the connecting bolt 14 becomes easy.

[0101] (2) When the protrusions 15 and recesses 25 are fitted together, relative movement between the holding members 31, 41 and the fixing member 21 in the direction along the outer surface 23b of the standing plate portion 23 and the inner surface 35a of the connecting plate portion 35 can be restricted. Therefore, when inserting the connecting bolt 14 into the through hole 35c and threading the connecting bolt 14 into the female thread 24, it is not necessary to manually hold the holding members 31, 41 and the fixing member 21 to prevent them from moving. This makes it easier to connect the holding members 31, 41 and the fixing member 21 with the connecting bolt 14.

[0102] (3) The protrusion 15 has arcuate surfaces 18 on both ends in the vertical direction Z. Therefore, when attempting to move each of the holding members 31, 41 upward, the arcuate surfaces 18 slide against the recess-forming surfaces 26, allowing each of the holding members 31, 41 to move upward. This makes it easy to separate the fixing member 21 and each of the holding members 31, 41.

[0103] (4) When attempting to move each of the holding members 31, 41 upward relative to the fixed member 21, each of the holding members 31, 41 allows the first convex portion forming surface 17a to move beyond the first concave portion forming surface 26a. Therefore, each of the holding members 31, 41 can be moved upward relative to the fixed member 21.

[0104] (5) The adhesive mat 12 is compressible and deformable in the thickness direction. The protrusion 15 includes an arcuate surface 18. When the holding members 31 and 41 are moved upward, the sliding between the arcuate surface 18 and the first recess-forming surface 26a exerts a force on the fixing member 21 that moves the upright plate portion 23 toward the base 93. At this time, the compressive deformation of the adhesive mat 12 causes the fixing member 21 to tilt. This means that the relative positions of the holding members 31 and 41 and the fixing member 21 can be changed. Changing the relative positions of the holding members 31 and 41 and the fixing member 21 reduces the sliding resistance between the arcuate surface 18 and the first recess-forming surface 26a, making it easier to remove the protrusion 15 from the recess 25. This facilitates the removal of the holding members 31 and 41 from the fixing member 21.

[0105] (6) The protrusion 15 has an arcuate surface 18 as a tilting guide. Therefore, when the holding members 31, 41 are moved upward, the arcuate surface 18 allows the protrusion 15 to slide smoothly against the recessed portion forming surface 26. As a result, the resistance associated with the sliding can be reduced, and the fixing member 21 can be tilted smoothly.

[0106] (7) 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 divided body 20 and the second divided body 40 has a portion inclined with respect to the shaft portion 92. Therefore, each of the first divided body 20 and the second divided body 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.

[0107] (8) The first divided body 20 can move in the second direction Y by utilizing the gap 39 between the first connecting wall 38 and the standing plate portion 23. The second divided body 40 can also move in the second direction Y by utilizing the gap 39 between the second connecting wall 45 and the groove-forming piece 43 and the standing plate portion 23. By utilizing the gap 39, the holding members 31, 41 can be separated from the fixing member 21 until the convex portion 15 comes out of the concave portion 25. Therefore, the holding members 31, 41 can be easily separated from the fixing member 21.

[0108] (9) The first divided body 20 can form a gap 39 between the first connecting wall 38 and the standing plate portion 23. Furthermore, the second divided body 40 can form a gap 39 between the second connecting wall 45 and the groove-forming piece 43 and the standing plate portion 23. Therefore, by utilizing the gap 39, each holding member 31, 41 can make the connecting plate portion 35 and the standing plate portion 23 face each other without the protrusion 15 entering the recess 25. Therefore, after making the connecting plate portion 35 and the standing plate portion 23 face each other, the protrusion 15 can be fitted into the recess 25. This facilitates the assembly of each holding member 31, 41 and the fixing member 21.

[0109] (10) When each holding member 31, 41 is moved in the second direction Y relative to the fixed member 21 so as to move away from the base 93, each holding member 31, 41 can move so that the holding member-side end 171 passes over the fixed member-side end 261. Therefore, each holding member 31, 41 can be moved in the second direction Y so as to move away from the fixed member 21. In this configuration, even if an object is present above each holding member 31, 41, each holding member 31, 41 can be separated from the fixed member 21. In other words, the assembly of each holding member 31, 41 and the fixed member 21 can be released.

[0110] (11) The adhesive mat 12 is compressible and deformable in the thickness direction. Therefore, the adhesive mat 12 is deformed by earthquake shaking, and is therefore less likely to peel off due to earthquake shaking. This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0111] In each fixing member 21, the recess 25 may be a groove recessed from the upper end of the standing plate portion 23. In this case, the recess forming surface 26 of the recess 25 does not have the first recess forming surface 26a, but the second recess forming surface 26b is the same as in the embodiment. The third recess forming surface 26c and the fourth recess forming surface 26d are flat surfaces facing the first direction X, but extend from the second recess forming surface 26b to the upper end of the standing plate portion 23.

[0112] When the protrusions 15 are fitted into the recesses 25, the contact between the second recess-forming surfaces 26b and the second protrusion-forming surfaces 17b restricts downward relative movement between the holding members 31, 41 and the fixing member 21. The contact between the third recess-forming surfaces 26c and the third protrusion-forming surfaces 17c, and the contact between the fourth recess-forming surfaces 26d and the fourth protrusion-forming surfaces 17d restricts relative movement between the holding members 31, 41 and the fixing member 21 in the first direction X.

[0113] In this configuration, movement of each holding member 31, 41 is not restricted by the engagement between the convex portion 15 and the concave portion 25, either when the holding members 31, 41 are moved upward or when the holding members 31, 41 are moved in the second direction Y. Therefore, the concave portion 25 serving as interference avoidance means allows movement of each holding member 31, 41 in directions that move the holding members 31, 41 away from the fixed member 21, and in both directions perpendicular to the fixed surface F and parallel to the fixed surface F. Therefore, the concave portion 25 recessed from the upper end of the standing plate portion 23 serves as interference avoidance means.

[0114] In each fixing member 21, the first dimension N1 of the recess 25 is made larger than in the embodiment. Then, with the protrusion 15 and the recess 25 fitted together, the first protrusion-forming surface 17a and the first recess-forming surface 26a may be separated in the vertical direction Z. In this case, the protrusion 15 and the recess 25 are fitted together due to contact between the third protrusion-forming surface 17c and the third recess-forming surface 26c, and contact between the fourth protrusion-forming surface 17d and the fourth recess-forming surface 26d. Therefore, relative movement between each holding member 31, 41 and the fixing member 21 in the first direction X is restricted.

[0115] The fixed body 10 may be formed, for example, by only the first divided body 20. In this case, the holding portion is formed by a pair of extending arms 36 and a retaining member that is hung between the pair of extending arms 36. The retaining member prevents the installation body 90 from slipping out from the tip of the pair of extending arms 36. The retaining member is, for example, a bolt that is hung between the pair of extending arms 36. In this case, the pair of extending arms 36 have attachment portions that extend upward. When the bolt is attached to the pair of attachment portions, the bolt is hung between the pair of extending arms 36. As a result, the bolt prevents the installation body 90 from slipping out from the tip of the pair of extending arms 36.

[0116] Although the fixed body 10 has two fixing portions 22, it may have one fixing portion 22. In this case, the fixed body 10 is formed only from the first divided body 20 and the second holding member 41. In other words, the fixed body 10 has only the fixing portion 22 of the first divided body 20. In this case, the first holding member 31 and the second holding member 41 are assembled with the assembly bolts 16 to form the fixed body 10 as a single unit.

[0117] An arcuate surface may be provided on the first recess-forming surface 26a as a tilt guide and interference avoidance means. In this case, the arcuate surface 18 of the protrusion 15 may or may not be present. The arcuate surface is formed so that the first dimension N1 increases from the first recess-forming surface 26a toward the outer surface 23b.

[0118] In each divided body 20, 40, the fixing portion 22 and the standing plate portion 23 of the fixing member 21 may be perpendicular to each other. Also, the base portion 33 and the connecting plate portion 35 of the first holding member 31 and the second holding member 41 may be perpendicular to each other. In each divided body 20, 40, the fixing portion 22 and the extending arm portion 36 may be opposed to each other in the vertical direction Z with the standing plate portion 23 and the connecting plate portion 35 overlapping each other. In this case, the base 93 of the support leg 91 is placed on the upper surface of the fixing portion 22. The base 93 is disposed between the upper surface of the base 93 and the lower surface of the extending arm portion 36.

[0119] The fixed body 10 may include a spacer for reducing the gap between the upper surface of the base 93 and the lower surface of the extending arm portion 36 of the first divided body 20. In this case, it is preferable that the spacer be attached to the first holding member 31 so that a gap 39 in the second direction Y is formed between the spacer and the standing plate portion 23.

[0120] In each of the first divided body 20 and the second divided body 40, the protrusions 15 may be provided on the upright plate portions 23, and the recesses 25 may be provided on the connecting plate portions 35. In this case, an overlapping portion is formed where the convex portion 15 and the concave portion 25 overlap. The overlapping portion is formed by a second concave portion-forming surface formed on the connecting plate portion 35 as the holding member-side overlapping surface, and a second convex portion-forming surface formed on the standing plate portion 23 as the fixing member-side overlapping surface. The second concave portion-forming surface and the second convex portion-forming surface are located at the lower end in the up-down direction Z of the overlapping portion of the convex portion 15 and the concave portion 25.

[0121] In the overlapping portion, the second recessed portion forming surface of the connecting plate portion 35 has a holding member side end portion 171. The holding member side end portion 171 is an end portion located on the shaft portion 92 side held by the extending arm portion 36, of both ends in the overlapping direction of the second recessed portion forming surface.

[0122] In the overlapping portion, the second convex portion forming surface of the standing plate portion 23 has a fixing member side end portion 261. The fixing member side end portion 261 is the end portion opposite to the shaft portion 92 side held by the extending arm portion 36, of both ends in the overlapping direction of the second convex portion forming surface.

[0123] When the connecting plate portion 35 and the standing plate portion 23 are connected by the connecting bolt 14, the holding member side end portion 171 and the fixing member side end portion 261 are located at opposite ends in the overlapping direction. The holding member side end portion 171 is located closer to the shaft portion 92 than the fixing member side end portion 261.

[0124] When each holding member 31, 41 is moved upward relative to the fixing member 21, the second recess forming surface on the side of the fixed surface F in the vertical direction Z can move beyond the second convex forming surface on the opposite side of the fixed surface F in the vertical direction Z.

[0125] In either the first divided body 20 or the second divided body 40, the protrusion 15 may be provided on the upright plate portion 23, and the recess 25 may be provided on the connecting plate portion 35. In the first divided body 20 and the second divided body 40, the inner surface 23a of the standing plate portion 23 and the outer surface 35b of the connecting plate portion 35 may be overlapped so as to face each other.

[0126] The second holding member 41 may not have the groove forming piece 43. In this case, the gap 39 between the connecting plate portion 35 and the groove forming piece 43 will be eliminated. The first connecting wall 38 of the first holding member 31 and the second connecting wall 45 of the second holding member 41 may be omitted. In this case, the gap 39 between the first connecting wall 38 and the connecting plate portion 35 and the gap 39 between the second connecting wall 45 and the connecting plate portion 35 are eliminated.

[0127] The adhesive mat 12 does not need to be compressively deformed. The installation body 90 may be a clock installed on a wall. In this case, the fixed surface is the wall surface. The installation body 90 may also be a lighting fixture installed on a ceiling. In this case, the fixed surface is the ceiling surface. The installation body 90 may also be a shelf installed on the floor. In this case, the shelf may be fixed by a fixing body 10 fixed to the wall. In this case, the fixed surface is the wall surface.

[0128] Next, the technical ideas that can be understood from the above-described embodiment and other examples will be described below together with their effects. (i) A direction parallel to the fixed surface and a direction in which the connecting plate portion moves away from the standing plate portion are defined as one direction, and a gap is provided between the protrusion and the connecting plate portion, and the gap allows the convex portion to move out of the concave portion due to relative movement of the fixing member and the retaining member in the one direction.
