[0004] Patent Document 1: Japanese Patent Application Publication No. 2021-133447 Summary of the invention Problems to be solved by the invention

[0005] In the wiring guide described in Patent Document 1, since the inner diameter of the pair of half-split rings is constant, it is difficult to apply wiring having an outer diameter different from the inner diameter. In addition, since the curvature radius of the inner surface of the bundling sheet is constant, it is difficult to fix the supporting fixing portion to a robot arm having an outer peripheral surface having a curvature radius different from the curvature radius of the inner surface. Solutions to Solve Problems

[0006] Various aspects of a fixing tool and a method of using the fixing tool for solving the above-mentioned problems are described. [Aspect 1] A fixing device for a device having a slender first object and a slender second object arranged along the first object, the first object and the second object being fixed by being assembled to a bracket fixed to the second object, the fixing device comprising: a fastening member extending in the circumferential direction of the outer peripheral surface of the first object and fastened to the first object; and a connecting mechanism connecting the bracket and the fastening member, when a direction orthogonal to both an extending direction of the first object and an arrangement direction of the bracket and the fastening member is taken as a width direction, the connecting mechanism comprises: a base portion assembled to the bracket; a clamping portion interposed between the fastening member and the first object, at least one of the base portion and the clamping portion being provided with a plurality of portions in the width direction.

[0007] According to this structure, the fastening member is fastened to the elongated first object, and the bracket is fixed to the elongated second object. Furthermore, the fastening member and the bracket are connected via the connection mechanism, so that the first object and the second object are fixed via the fastening member, the connection mechanism and the bracket.

[0008] [Aspect 2] In the fixing tool described in aspect 1, the base portion is provided at one in the width direction, and the clamping portion is provided at a plurality in the width direction, and the clamping portion is rotatably mounted on the base portion.

[0009] In the aspect that the base part is provided with a plurality of parts in the width direction, it takes time to position each base part with high precision. In contrast, according to this structure, since the base part is provided with a single part in the width direction, it is easy to position the base part with high precision. In addition, since the clamping part can be rotatably mounted on the base part, the clamping part can be easily arranged along the outer peripheral surface of the first object. As a result, the fastening force of the fastening member can easily act further on the first object in its radial direction via the clamping member. Therefore, the force of holding the first object by the fastening member can be effectively increased.

[0010] [Aspect 3] In the fixing tool described in claim 1, a plurality of the base portion and the interposing portion are provided in the width direction, and are configured to be arranged so that the intervals therebetween in the width direction can be changed.

[0011] According to this structure, a bracket having a size corresponding to the size of the second object in the width direction can be mounted on the base portion, and the interval between the clamping portions can be changed according to the size of the first object in the width direction. Therefore, the fixture can be applied to the first object of different sizes in the width direction, and the fixture can be applied to the second object of different sizes in the width direction.

[0012] [Aspect 4] In the fixing device described in aspect 2, the base portion is a base member having an assembly portion, a pair of arm portions and a connecting shaft, the assembly portion can be detachably mounted on the bracket, the pair of arm portions are arranged at intervals from each other in the extension direction, the connecting shaft extends along the extension direction and connects the arm portions to each other, and the clamping portion is supported by the connecting shaft and is configured to be a transmission member that transmits the fastening force of the fastening member to the outer peripheral surface of the first object.

[0013] According to this configuration, since the transmission member is pressed from the outer peripheral side by the fastening member, the fastening force of the fastening member acts on the first object in the radial direction thereof via the transmission member. Therefore, the force of the fastening member to hold the first object can be increased.

[0014] [Aspect 5] In the fixture described in any one of Aspects 1 to 4, the base portion has a mounting portion that is detachably mounted to the bracket, and the base portion is configured to be able to change the position of the mounting portion relative to the clamping portion in the arrangement direction.

[0015] According to this configuration, by changing the position of the mounting portion relative to the interposing portion in the arrangement direction, the interval between the first object and the second object in the arrangement direction can be changed. [Aspect 6] A method for using a fixing device, wherein the fixing device is the fixing device described in any one of Aspects 1 to 5, and the method for using comprises: when the base portion is provided with a plurality of base portions in the width direction, setting the interval between the base portions according to the size of the bracket in the width direction; and when the clamping portion is provided with a plurality of clamping portions in the width direction, setting the interval between the clamping portions according to the size of the first object in the width direction.

[0016] According to this method, the same function and effect as the fixing tool described in any one of the first to fifth aspects can be achieved. Effects of the Invention

DETAILED DESCRIPTION

[0019] Below, refer to Figure 1 to Figure 5B The fixing tool and the method of using the fixing tool according to the first embodiment will be described. <First Embodiment> like Figure 1 As shown, the fixture 10 is applied to a device 70 including an elongated first object 71 and an elongated second object 72 arranged along the first object 71 .

[0020] The first object 71 is, for example, a robot arm having a substantially circular cross section. The second object 72 is, for example, a cable having a substantially circular cross section. The fixture 10 is attached to the bracket 40 fixed to the second object 72 to fix the first object 71 and the second object 72. The fixture 10 and the bracket 40 constitute a fixing device that fixes the first object 71 and the second object 72.

[0021] In addition, the extending direction ( Figure 1 The left-right direction) is taken as the extension direction X, and the arrangement direction of the bracket 40 and the fastening member 11 ( Figure 1The up and down direction) is taken as the arrangement direction Y, and the direction perpendicular to both the extension direction X and the arrangement direction Y is taken as the width direction Z.

[0022] Next, the structures of the fixing tool 10 and the bracket 40 will be described in detail. <Fixing tool 10> like Figure 1 and Figure 2 As shown, the fixture 10 includes a fastening member 11 extending along the circumferential direction C of the outer peripheral surface of the first object 71 and fastened to the first object 71 , and a connecting mechanism 14 connecting the bracket 40 and the fastening member 11 .

[0023] <Fastening member 11> like Figure 1 and Figure 2 As shown, the fastening member 11 has a strap 12 and a buckle 13 . A hook (not shown) and a loop (not shown) constituting a surface fastener are provided at an end portion of one surface of the belt 12 and at a portion connected to the end portion, respectively.

[0024] like Figure 2 As shown, the two ends of the belt 12 are respectively inserted into the holes of the buckle 13 (not shown) and folded toward the outer peripheral surface of the belt 12, so that the overlapping parts of the belt 12 are detachably joined by utilizing the function of the above-mentioned surface fastener.

[0025] <Connection mechanism 14> like Figure 1 to Figure 3 As shown, the connection mechanism 14 includes two base members 20 as an example of a base portion, which are attached to the bracket 40 , and two transmission members 30 as an example of an intervening portion, which are interposed between the fastening member 11 and the first object 71 .

[0026] <Base member 20> like Figure 3 and Figure 4 As shown, the two base members 20 are arranged in plane symmetry with respect to a symmetry plane orthogonal to the width direction Z. Therefore, hereinafter, the structure of one of the base members 20 will be described, and the description of the structure of the other will be omitted.

[0027] The base member 20 of the first embodiment has a shape that is plane-symmetrical with respect to a symmetry plane that is orthogonal to the extending direction X. Therefore, the two base members 20 have the same shape. The base member 20 includes a main body 21 , an attachment portion 22 detachably attached to the bracket 40 , a pair of arms 23 spaced apart from each other in the extension direction X, and a connecting shaft 24 extending in the extension direction X and connecting the arms 23 .

[0028] The main body portion 21 extends along the arrangement direction Y and is adjacent to the bracket 40 in the width direction Z. The fitting portion 22 protrudes from a middle portion of the main body portion 21 in the arrangement direction Y toward the other base member 20 in the width direction Z. The fitting portion 22 is provided with a hole 22 a penetrating in the arrangement direction Y.

[0029] The pair of arms 23 protrude from the main body 21 toward the fastening member 11 in the arrangement direction Y. The interval between the arms 23 is greater than the length of the belt 12 in the extension direction X and the length of the transmission member 30 described later.

[0030] The base member 20 is formed of, for example, a hard resin material. The two base members 20 are arranged so that the interval between them in the width direction Z can be changed.

[0031] <Transmission member 30> like Figure 3 and Figure 4 As shown, the two transmission members 30 have the same shape. The two transmission members 30 are arranged to be plane-symmetrical with respect to a symmetry plane orthogonal to the width direction Z. Therefore, hereinafter, the structure of one of the transmission members 30 will be described, and the description of the structure of the other will be omitted.

[0032] The transmission member 30 is in the shape of a thin plate extending along the circumferential direction C. The length of the transmission member 30 in the extending direction X is constant throughout the entire circumferential direction C. A first protrusion 31 is provided at the center of the transmission member 30 in the circumferential direction C. The first protrusion 31 protrudes toward the outer circumference and extends in the extension direction X. Second protrusions 32 are provided on both sides of the first protrusion 31 in the circumferential direction C. The second protrusions 32 protrude toward the outer circumference and extend in the extension direction X.

[0033] A first groove 31 a extending in the extending direction X is provided on the inner peripheral surface of the transmission member 30 at a portion corresponding to the first protrusion 31 . The first groove 31a has an arc-shaped cross section. The connecting shaft 24 is fitted into the first groove 31a. The transmission member 30 is supported so as to be rotatable around the axis of the connecting shaft 24.

[0034] The transmission member 30 is assembled to the base member 20 by fitting the connecting shaft 24 of the base member 20 into the first groove 31 a of the transmission member 30 . Two second grooves 32 a extending in the extending direction X are respectively provided on the inner peripheral surface of the transmission member 30 at portions corresponding to the two second protrusions 32 .

[0035] The transmission member 30 is formed of a flexible resin material. The transmission member 30 is preferably formed of a material having viscoelasticity. That is, the transmission member 30 preferably has viscoelasticity. Examples of materials having viscoelasticity include elastomers. The transmission member 30 has viscoelasticity, so that the transmission member 30 is not easy to slide relative to the first object 71.

[0036] The transmission member 30 is configured to transmit the fastening force of the fastening member 11 to the outer peripheral surface of the first object 71. Since the transmission member 30 has three protrusions, namely the first protrusion 31 and the two second protrusions 32, the fastening force of the fastening member 11 can be appropriately dispersed and transmitted to the outer peripheral surface of the first object 71.

[0037] The two transmission members 30 are arranged so that the interval between them in the width direction Z can be changed. <Stand 40> like Figure 3 and Figure 4 As shown, the bracket 40 includes a first member 41 and a second member 51 . The first member 41 is mounted on the mounting portions 22 of the two base members 20 , and the second member 51 is rotatably mounted on the first member 41 .

[0038] The second member 51 is provided on the side opposite to the mounting portion 22 across the first member 41 in the arrangement direction Y ( Figure 3 and Figure 4 on the upper side of the ). <First member 41> like Figure 3 and Figure 4 As shown, the first member 41 includes a bottom wall 42 , a pair of first side walls 43 , and a pair of second side walls 44 .

[0039] The bottom wall 42 has a substantially rectangular plate shape having a pair of long sides extending in the width direction Z and a pair of short sides extending in the extending direction X. The bottom wall 42 abuts against the two fitting portions 22 . The pair of first side walls 43 extends from a pair of edge portions corresponding to a pair of long sides of the bottom wall 42 toward a side opposite to the mounting portion 22 in the arrangement direction Y.

[0040] The pair of second side walls 44 extends from a pair of edge portions corresponding to a pair of short sides of the bottom wall 42 toward a side opposite to the mounting portion 22 in the arrangement direction Y. The bottom wall 42 is provided with two holes 42 a extending through the bottom wall 42 in the arrangement direction Y at a distance from each other in the width direction Z.

[0041] The first member 41 is mounted to the two mounting portions 22 by inserting the bolts 61 through the holes 22 a of the two mounting portions 22 and the two holes 42 a of the bottom wall 42 and screwing the nuts 62 onto the bolts 61 .

[0042] The pair of first side walls 43 are provided with a first support portion 45 . The first support portion 45 has a semicircular concave shape and supports the outer peripheral surface of the second object 72 . In the width direction Z, on one side ( Figure 3 and Figure 4 A shaft portion 46 is provided on the outer side of the second side wall 44 (on the left side of the body), and the shaft portion 46 connects the pair of first side walls 43 to each other.

[0043] On the other side ( Figure 3 and Figure 4 The first locking portion 47 is provided on the second side wall 44 (on the right side of the ) of the second member 51. The first locking portion 47 protrudes toward the second member 51 further than the first side wall 43 in the arrangement direction Y, and has a claw portion.

[0044] <Second Component 51> like Figure 3 and Figure 4 As shown, the second member 51 includes: a top wall 52 facing the bottom wall 42 in the arrangement direction Y; and a pair of first side walls 53 and a pair of second side walls 54 connected to the top wall 52 and extending along the arrangement direction Y respectively.

[0045] The pair of first side walls 53 faces each other in the extending direction X. The pair of second side walls 54 faces each other in the width direction Z. The pair of first side walls 53 are provided with second support portions 55, which are semicircular concave shapes and support the outer peripheral surface of the second object 72. The first support portions 45 and the second support portions 55 form a substantially circular support hole.

[0046] A bearing 56 is provided at the end edge of one second side wall 54. The bearing 56 is configured to be rotatable by engaging with the shaft 46 of the first member 41. The second member 51 is configured to be rotatable relative to the first member 41 about the axis of the shaft 46.

[0047] The second side wall 54 on the other side is provided with a second locking portion 57 that can be locked with the first locking portion 47. The second locking portion 57 of the first embodiment is a convex portion that is locked with the claw portion of the first locking portion 47. The first locking portion 47 is locked with the second locking portion 57, thereby restricting the rotation of the second member 51 relative to the first member 41.

[0048] Next, the operation of the first embodiment will be described. The fastening member 11 is fastened to the elongated first object 71, and the bracket 40 is fixed to the elongated second object 72. The fastening member 11 and the bracket 40 are connected via the connection mechanism 14, so that the first object 71 and the second object 72 are fixed via the fastening member 11, the connection mechanism 14, and the bracket 40.

[0049] like Figure 5A As shown, when the size of the holder 40 in the width direction Z, that is, the size of the second object 72 is small, the interval between the base members 20 is set to be small. On the other hand, Figure 5B As shown, when the size of the holder 140 in the width direction Z, that is, the size of the second object 172 is large, the interval between the base members 20 is set to be large.

[0050] In this way, since two base members 20 are provided in the width direction Z, the interval between the base members 20 can be changed according to the size of the bracket 40 (140) in the width direction Z, that is, the size of the second object 72 (172). Thus, the bracket 40 (140) having a size corresponding to the size of the second object 72 (172) in the width direction Z can be mounted on the base member 20.

[0051] In addition, since two transmission members 30 are provided in the width direction Z, the interval between the transmission members 30 can be changed according to the size of the first object 71 (171) in the width direction Z. Thus, the first object 71 (171) of different sizes in the width direction Z can be fastened to the transmission member 30.

[0052] Next, the effects of the first embodiment will be described. (1-1) In the fixture 10, two base members 20 and two transmission members 30 are provided in the width direction Z. The two base members 20 are arranged so that the interval between them in the width direction Z can be changed. The two transmission members 30 are arranged so that the interval between them in the width direction Z can be changed.

[0053] According to such a configuration, since the above-mentioned function is achieved, the fixture 10 can be applied to the first object 71 having different sizes in the width direction Z, and the fixture 10 can be applied to the second object 72 having different sizes in the width direction Z.

[0054] (1-2) The transmission member 30 is supported by the connecting shaft 24 of the base member 20 , and is configured to transmit the fastening force of the fastening member 11 to the outer peripheral surface of the first object 71 . According to such a structure, since the transmission member 30 is supported by the connecting shaft 24 and interposed between the first object 71 and the fastening member 11, the transmission member 30 is pressed from the outer peripheral side by the fastening member 11. Thus, the fastening force of the fastening member 11 acts on the first object 71 in the radial direction thereof via the transmission member 30. Therefore, the force of the fastening member 11 to hold the first object 71 can be increased.

[0055] (1-3) The transmission member 30 extends along the circumferential direction C, and is supported so as to be rotatable about the axis of the connecting shaft 24 . According to such a structure, the transmission member 30 rotates around the axis of the connecting shaft 24, so that the transmission member 30 easily follows the outer peripheral surface of the first object 71. As a result, the fastening force of the fastening member 11 easily acts further in the radial direction of the first object 71 via the transmission member 30. Therefore, the force of the fastening member 11 to hold the first object 71 can be effectively increased.

[0056] (1-4) The transmission member 30 has flexibility. Therefore, the transmission member 30 is deformed by bending along the outer peripheral surface of the first object 71. Therefore, the force of holding the first object 71 by the fastening member 11 can be effectively increased.

[0057] (1-5) The method of using the fixing tool 10 includes: setting the interval between the base members 20 according to the size of the bracket 40 in the width direction Z; and setting the interval between the transmission members 30 according to the size of the first object 71 in the width direction Z.

[0058] According to such a method, the same effect as that of the above-mentioned (1) can be achieved. Below, refer to Figure 6 and Figure 7 The fixing tool and the method of using the fixing tool according to the second embodiment will be described. The shape of the transmission member 30 of the fixing tool 10 according to the second embodiment is different from that of the first embodiment.

[0059] <Second Embodiment> like Figure 6 and Figure 7 As shown in FIG. 1 , the transmission member 30 of the second embodiment is in the shape of a thin plate. The transmission member 30 is in the shape of a rectangle in a plan view, and the longitudinal direction thereof is slightly curved in the thickness direction.

[0060] like Figure 1 and Figure 2 As shown, when the fixture 10 is applied to a device 70 including an elongated first object 71 and an elongated second object 72 disposed along the first object 71 , the transmission member 30 extends along the circumferential direction C.

[0061] The length of the transmission member 30 along the circumferential direction C is constant. In addition, the thickness of the transmission member 30 perpendicular to the circumferential direction C is constant. The surface of the outer peripheral side of the curve of the transmission member 30, that is, the outer surface, is composed of a curved surface along the circumferential direction C. In addition, the surface of the inner peripheral side of the curve of the transmission member 30, that is, the inner surface, is also composed of a curved surface along the circumferential direction C.

[0062] A first groove 31a extending in the extension direction X is provided on the inner peripheral surface of the transmission member 30 at the center portion in the longitudinal direction of the transmission member 30. The transmission member 30 is rotatably mounted on the base member 20 by fitting the connecting shaft 24 of the base member 20 into the first groove 31a of the transmission member 30. That is, the interposed portion is rotatably mounted on the base portion.

[0063] The transmission member 30 may include a second groove 32a in addition to the first groove 31a. That is, the transmission member 30 may include the second groove 32a at a position different from the first groove 31a on the inner peripheral surface.

[0064] The operation and effects of the second embodiment will be described. (2-1) The transmission member 30 is rotatably mounted on the base member 20. Therefore, the transmission member 30 can easily follow the outer peripheral surface of the first object 71. As a result, the fastening force of the fastening member 11 can easily act further on the first object 71 in the radial direction thereof via the transmission member 30. Therefore, the force of the fastening member 11 to hold the first object 71 can be effectively increased. In addition, the transmission member 30 can also easily follow the outer surface of the first object 71 of different sizes.

[0065] (2-2) The outer surface and the inner peripheral surface of the transmission member 30 are formed of curved surfaces along the circumferential direction C. Therefore, it is easy to make the fastening force of the fastening member 11 act evenly on the first object 71 .

[0066] <Modification> The first embodiment and the second embodiment (hereinafter also referred to as the present embodiment) described above can be implemented as, for example, the following modifications. The present embodiment and the following modifications can be implemented in combination with each other within the scope of no technical contradiction.

[0067] The fastening member 11 is not limited to a member including the buckle 13 or a member including a surface fastener. For example, the fastening member can be embodied as a hose clamp or an insulation lock.

[0068] The first object 71 is not limited to a robot arm. In addition, the second object 72 is not limited to a cable. The first object and the second object only need to be elongated, and the fixture can be applied to objects other than a robot arm or a cable.

[0069] For example, Figure 8As shown in the first modification example, the main body 21 and the mounting portion 22 of the base member 20 can also be separated. In this case, the main body 21 is provided with a plurality of holes 21a that penetrate along the width direction Z at intervals in the arrangement direction Y. In addition, the mounting portion 22 is provided with an internal thread 22b that extends along the width direction Z. And, by inserting a screw 81 through one of the plurality of holes 21a and screwing it into the internal thread 22b of the mounting portion 22, the mounting portion 22 is fixed to the main body 21.

[0070] According to such a configuration, by changing the hole 21a through which the screw 81 is inserted, the position of the attachment portion 22 relative to the transmission member 30 can be changed in the arrangement direction Y. Therefore, the interval between the first object 71 and the second object 72 in the arrangement direction Y can be changed.

[0071] In addition, the fixing method of the mounting portion 22 to the main body portion 21 is not limited to the fastening by the screws 81 , and may also be a snap fit. For example, Fig. 9 As in the second modified example shown in FIG. 1 , the assembly portion 22 protruding from the main body 21 in the width direction Z can be omitted, and the assembly portion can be formed by using the hole 21a that penetrates the main body 21 in the width direction Z. In this case, the main body 21 is provided with a plurality of holes 21a spaced apart from each other in the arrangement direction Y. In addition, the first member 41 of the bracket 40 is provided with an internal thread 41a extending in the width direction Z. And, the screw 81 is inserted through one of the plurality of holes 21a and screwed into the internal thread 41a of the first member 41.

[0072] According to such a structure, the same effect as the first modification can be achieved. In addition, the fixing method of the bracket 40 to the main body 21 is not limited to the fastening by the screws 81 , and may also be a buckle.

[0073] For example, Fig. 10A and Fig. 10B As shown in the third modification, the base member 20 may include two connecting shafts 24A and 24B. In this case, the main body 21 is provided with two pairs of arm portions 23A and 23B.

[0074] like Fig. 10A As shown in the figure, a pair of arm portions 23A protrude from the main body 21 toward the fastening member 11 (the lower side of the figure) in the arrangement direction Y. Another pair of arm portions 23B protrude from the main body 21 toward the side opposite to the pair of arm portions 23A (the upper side of the figure) in the arrangement direction Y. A connecting shaft 24A is provided between the arm portions 23A. In addition, a connecting shaft 24B is provided between the arm portions 23B. In addition, the assembly portion 22 is provided at a position closer to the connecting shaft 24B than the central position of the main body 21 in the arrangement direction Y.

[0075] According to this structure, Fig. 10B As shown in FIG. 1 , the base member 20 can be used by being reversed in the arrangement direction Y. In this case, the position of the mounting portion 22 in the arrangement direction Y is the same as that in FIG. Fig. 10A The usage shown is closer to the transmission member 30. Therefore, the interval between the first object 71 and the second object 72 in the arrangement direction Y can be changed according to the posture of the base member 20.

[0076] That is, in the first to third modified examples, the base member 20 is configured so that the position of the mounting portion relative to the transmission member 30 in the arrangement direction Y can be changed. ·like Figure 3 As shown, in the present embodiment, the assembly portion 22 of the base member 20 has a hole 22a that penetrates along the arrangement direction Y, but is not limited to this mode. The assembly portion 22 of the base member 20 may also have a plurality of holes 22a that penetrate along the arrangement direction Y. In addition, the bottom wall 42 of the first member 41 may also have a plurality of holes 42a for a plurality of bolts 61 that are inserted through the plurality of holes 22a. In this mode, the assembly portion 22 of the base member 20 has a plurality of holes 22a that penetrate along the arrangement direction Y, thereby suppressing the relative rotation of the base member 20 relative to the first member 41. Therefore, it is easy to position the base member 20 relative to the first member 41.

[0077] In the above-mentioned embodiment and modification, the transmission member 30 having one first groove 31a and two second grooves 32a is exemplified, but the two second grooves 32a may be replaced with the first groove 31a. In this case, the first groove 31a into which the connecting shaft 24 is inserted among the three first grooves 31a may be appropriately changed according to the size of the first object 71 in the width direction Z.

[0078] The transmission member 30 only needs to have at least one first groove 31a, and the number of second grooves 32a may be changed or omitted. That is, the number of second protrusions 32 is not limited to two, and may be three or more or one. The second protrusion 32 may also be omitted.

[0079] The transmission member 30 is preferably supported so as to be rotatable about the axis of the connecting shaft 24. Furthermore, the transmission member 30 is preferably flexible. When the transmission member 30 is flexible, it may be made of a material other than a resin material, such as a rubber material or a metal material. In addition, the transmission member 30 is not limited to a member extending in the circumferential direction C in a natural state in which no tightening force is applied by the tightening member 11. The transmission member may have a substantially flat plate shape in a natural state, and on the other hand, may be bent in the circumferential direction C by being tightened by the tightening member 11.

[0080] The transmission member 30 may be fixed to the connecting shaft 24 in a non-rotatable manner. The transmission member 30 can also be omitted. In this case, the connection shaft 24 in the base member 20 functions as an intervening portion, and the structure other than the connection shaft 24 in the base member 20 functions as a base portion.

[0081] In the above-described embodiment and modified example, a structure in which two base portions are provided in the width direction Z is exemplified. However, three or more base portions may be provided in the width direction Z. In the above-described embodiment and modified example, the result of providing two intervening portions in the width direction Z is exemplified. However, three or more intervening portions may be provided in the width direction Z.

[0082] · As long as a plurality of base parts are provided in the width direction Z, the number of intervening parts can be reduced to only one. In addition, as long as a plurality of intervening parts are provided in the width direction Z, the number of base parts can be reduced to only one.

[0083] For example, Fig.11 , 12 As shown in the fourth modification example, the two base members 20 in this embodiment may be integrated into one base member 20. Fig.11 , 12 In the example, one base member 20 is formed by a single piece in which two base members 20 are integrated. That is, this one base member 20 has an assembly portion 22 and two main body portions 21 provided at both ends of the assembly portion 22, and the assembly portion 22 has two holes 22a. In the method with two base members 20, it takes time to position each base member 20 with high precision. In contrast, when the base member 20 is one, it is easy to position the base member 20 with high precision. In addition, since the number of parts is reduced, the working efficiency can also be improved.

[0084] In addition, the base member 20 of the fourth modified example can also be formed into one base member 20 by joining two separate base members 20. For example, the two separate base members 20 can be joined by joining with bolts or adhesives. Depending on the purpose, one base member 20 can also be separated and used as two base members 20. That is, one base member 20 can also be separated into two base members 20.

[0085] The bracket is not limited to the structure described in the above-mentioned embodiment and modification, that is, the split type having the first member and the second member, but may also be an integrated type consisting of one member. In short, the bracket can be any shape as long as it has a shape that fixes the second object, for example, it may be a plate-shaped member that supports a part of the outer peripheral surface of the second object.

[0086] The interval between the base parts can be set not only according to the size in the width direction of the stand but also according to the length or shape. The interval between the intervening portions can be set not only according to the size in the width direction of the first object but also according to the length or shape.
