Mode for Carrying Out the Invention

[0008] <First Embodiment> A connector 1 according to one embodiment will be described below with reference to the respective drawings. As shown in FIG. 1, the connector 1 is a member that connects a suspension bolt B1 and two vibration-proofing bolts B2. The suspension bolt B1 is a fully threaded bolt that extends vertically, connects a facility E to a ceiling, and suspends the facility E. The vibration-proofing bolt B2 is a fully threaded bolt that extends in a direction intersecting the suspension bolt B1 and prevents the facility E from swinging. Both the suspension bolt B1 and the vibration-proofing bolts B2 have external threads formed on their outer peripheral portions. Note that, to facilitate understanding of the structure, FIG. 2 depicts the vibration-proofing bolts B2 in a vertically extending posture. Similarly, in other drawings, the vibration-proofing bolts B2 may be depicted in a vertically extending state.

[0009] Note that, with respect to the connector 1, as shown in FIGS. 1 to 5, the posture and position of the connector 1 in a state where the suspension bolt B1 and the vibration-proofing bolts B2 are attached are used as a reference to define axes and directions, which are used for describing the configuration, components, and the like. Specifically, an axis parallel to the extending direction of the suspension bolt B1 is defined as a Z-axis, and axes orthogonal to the Z-axis and further orthogonal to each other are defined as an X-axis and a Y-axis. Of the two vibration-proofing bolts B2 attached to the connector 1, one extends substantially parallel to the XZ plane, and the other extends substantially parallel to the YZ plane. As defined, the Z-axis direction is an axis extending in the vertical direction, and the X-axis and Y-axis are axes extending in the horizontal direction.

[0010] As shown in FIGS. 1 to 5, the connector 1 includes a base member 10, two holding members 20, and two connecting members 30.

[0011] The base member 10 has two opposing members 11 of the same shape, and is configured by combining these two opposing members 11.

[0012] As mainly shown in FIG. 3, the opposing member 11 is a member formed by bending a metal flat plate, and includes flat plate portions 12 and 13 formed in a substantially rectangular flat plate shape, intermediate portions 14 and 15, an end portion 16, and an end portion 17 corresponding to the end portions of the flat plate portions 12 and 13.

[0013] The flat plate portions 12 and 13 extend in directions perpendicular to each other. An opening 12A into which a connecting member 30 is inserted is formed in the center of the flat plate portion 12. Similarly, an opening 13A into which a connecting member 30 is inserted is formed in the center of the flat plate portion 13. The opening 12A is an elongated hole having a minor axis in the vertical direction and a major axis in the horizontal direction.

[0014] The flat plate portion 12 has horizontally extending edges 12B and 12C. The flat plate portion 13 also has a horizontally extending edge 13B. On the surface of the flat plate portion 13 facing the flat plate portion 12, a plurality of protrusions 13D are formed to hold the connecting member 30.

[0015] The intermediate portion 14 is a flat plate-shaped member that connects sides 12B and 13B and extends in a substantially horizontal direction. The intermediate portion 14 is formed in a substantially right-angled triangular shape when viewed in the Z-axis direction and has an edge portion 14A that extends in a direction of approximately 45 degrees with respect to the X-axis and Y-axis.

[0016] A notch 14B is formed in the center of the intermediate portion 14 to guide the suspension bolt B1 and to press and hold the outer circumference of the suspension bolt B1. The notch 14B is a cutout in the intermediate portion 14 and, when viewed in the Z-axis direction, extends from the center of the edge portion 14A toward the end portion 17 at an angle of approximately 45 degrees to the X and Y axes. The notch 14B has a wider width than the suspension bolt B1, allowing the suspension bolt B1 to move within it.

[0017] The intermediate portion 15 is a flat plate-shaped member that extends approximately horizontally from side 12C. The intermediate portion 15 is formed in an approximately triangular shape when viewed in the Z-axis direction.

[0018] A notch 15B is formed in the center of the intermediate section 15 to guide the suspension bolt B1 and to press and hold the outer circumference of the suspension bolt B1. When viewed in the Z-axis direction, the notch 15B is formed to cut out the edge of the intermediate section 15 toward the flat plate section 12.

[0019] The end portion 16 is a member that extends in the Z-axis direction and is formed to protrude from the end of the flat plate portion 13. The shape of the end portion 16 is not limited to this embodiment, and various shapes can be adopted, as in other embodiments described later.

[0020] The end portion 17 is located within the flat plate portion 12 at the end opposite to the flat plate portion 13, and extends in the Z-axis direction.

[0021] As described above, the base member 10 is formed by combining two opposing members 11 such that their ends 17 overlap. More specifically, the top and bottom of one of the opposing members 11 are reversed, the ends 17 of both members are overlapped, and the flat plate portion 12 and the flat plate portion 13 are overlapped in the X-axis direction, as well as in the Y-axis direction, thereby creating the combined state of these two opposing members 11.

[0022] Furthermore, by combining them in this way, the notches 14B and 15B face each other at two locations on the upper and lower parts of the foundation member 10, making it possible to clamp the suspension bolt B1.

[0023] The retaining member 20 is a member that holds the anti-vibration bolt B2 between itself and the base member 10. The retaining member 20 is a member formed by bending a metal plate and has a roughly rectangular parallelepiped shape.

[0024] The retaining member 20 has two side portions 21, each having an arc-shaped notch 21A. The two side portions 21 extend parallel to each other. The side portions 21 have the function of housing the anti-vibration bolt B2 in the notch 21A and holding it in place between them and the flat plate portion 12. A substantially circular opening 20B is formed in the center of the retaining member 20, into which the connecting member 30 is inserted.

[0025] The connecting member 30 includes a bolt 31, a nut 32, and a spring 33.

[0026] The bolt 31 is inserted into the openings 12A, 13A, and 20B and extends perpendicularly to the flat plate portion 12. The bolt 31 is male threaded. The head of the bolt 31 is housed between the projections 13D and is held non-rotatably by the projections 13D.

[0027] The nut 32 is a female thread that is joined to the bolt 31. The nut 32 is held in place by the retaining member 20 sandwiched between it and the spring 33.

[0028] The spring 33 is a metal helical spring located between the flat plate portion 12 and the retaining member 20, and in contact with both the flat plate portion 12 and the retaining member 20. The spring 33 has the function of holding the retaining member 20 between itself and the nut 32 by applying a biasing force toward the retaining member 20 toward the nut 32 through its own elastic force. The spring 33 also biases the flat plate portion 12 toward the flat plate portion 13 and the head of the bolt 31, preventing the flat plate portion 12 from moving unexpectedly.

[0029] The base member 10 can be deformed between an open state in which the notches 14B and 15B are separated from each other (Figure 5) and a held state in which the notches 14B and 15B are brought closer together, enabling the suspension bolt B1 to be held, by swinging the opposing member 11 around the axis AX (Figure 5(b)) formed by the abutment portions of the two ends 17. When no external force is acting, the holding state of the base member 10 is maintained by the biasing force of the spring 33.

[0030] (work) The process of connecting the suspension bolt B1 and the anti-vibration bolt B2 using the above-described connector 1 will be explained below.

[0031] First, the worker grasps the two ends 16 and applies force to bring them closer together, as shown by the white arrows in Figure 5. Against the biasing force of the spring 33, the base member 10 deforms, the overlapping flat sections 12 and 13 separate, and the notches 14B and 15B also separate, becoming open. The bolt 31 slides through the opening 12A along the long axis of the opening.

[0032] The worker keeps the foundation member 10 open and passes the suspension bolts B1 through the notches 14B and 15B at two locations on the top and bottom of the foundation member 10 (Figures 2, 4, etc.).

[0033] When the worker releases their hand from the end 16, the restoring force of the spring 33 causes the flat plate portions 12 and 13 to move closer together, and the notches 14B and 15B also move closer to each other. The notches 14B and 15B hold the suspension bolt B1 by pressing against the outer circumference of the suspension bolt B1.

[0034] Furthermore, by pressing the end portion 16 again, the worker can loosen the pressure on the notches 14B and 15B against the suspension bolt B1, and make adjustments such as shifting the holding position of the suspension bolt B1 up or down.

[0035] Next, the worker rotates the holding member 20 around the bolt 31, adjusting the angle so that the side portion 21 is perpendicular to the anti-vibration bolt B2.

[0036] The worker inserts the anti-vibration bolt B2 into the notch 21A and rotates the nut 32 to tighten it, thereby fixing the anti-vibration bolt B2 to the connector 1. When the nut 32 is tightened, the nut 32, the retaining member 20, and the spring 33 move against the biasing force and approach the flat plate portions 12 and 13. As a result, the anti-vibration bolt B2 is sandwiched and fixed between the side portion 21 and the flat plate portion 12 (Figures 2 and 4).

[0037] <Second Embodiment> The connector 100 according to the second embodiment will be described below with reference to Figures 6 to 9. Components similar to those in the first embodiment will be given the same reference numerals as in the first embodiment, and their descriptions will be omitted.

[0038] The connector 100 comprises a base member 110, two holding members 20, and two connecting members 30.

[0039] The base member 110 has two opposing members 111 of the same shape, and is constructed by combining these two opposing members 111.

[0040] The opposing member 111 is a member formed mainly by bending a metal plate, as shown in Figure 7, and has a flat plate portion 112, 113 formed in a substantially rectangular flat plate shape, an intermediate portion 114, 115, an end portion 116, and an end portion 117 corresponding to the end of the flat plate portion 112.

[0041] The flat plate portion 112 has horizontally extending sides 112B and 112C. The flat plate portion 113 has a horizontally extending side 113B. A projection 113D is formed on the surface of the flat plate portion 113 facing the flat plate portion 112, which can hold the connecting member 30 in a non-rotatable state when it is held. Openings 112A and 113A are formed in the center of each of the flat plate portions 112 and 113, into which the bolt 31 is inserted. The openings 112A and 113A are elongated holes with their long axes in the horizontal direction.

[0042] The intermediate section 114 connects sides 112B and 113B, extends substantially horizontally, and is partially bent. The intermediate section 114 is formed in a substantially triangular shape when viewed in the Z-axis direction.

[0043] A notch 114B is formed in the intermediate portion 114 by two sides extending perpendicularly to each other. The notch 114B has the function of pressing and holding the outer circumference of the suspension bolt B1.

[0044] The intermediate portion 115 is a flat plate-shaped member extending substantially horizontally from the side 112C. The intermediate portion 115 is formed in a substantially trapezoidal shape when viewed in the Z-axis direction. An end portion 115A is formed at the end of the intermediate portion 115, extending perpendicularly to the flat plate portion 112.

[0045] The end portion 116 is a member that extends in the Z-axis direction and is formed to protrude from the end of the flat plate portion 113. Viewed in the Z-axis direction, the end portion 116 is bent at two points. The shape of the end portion 116 is not limited to this embodiment, and various shapes can be adopted.

[0046] The end portion 117 is located at the end of the flat plate portion 112 and extends in the Z-axis direction. The end portion 117 faces the notch portion 114B.

[0047] The base member 110 is formed by combining two opposing members 111 such that their ends 117 abut against each other. More specifically, the top and bottom of one of the opposing members 111 are reversed, the ends 117 of both members are abutted against each other, and the flat plate portion 112 and the flat plate portion 113 are superimposed in the X-axis direction, as well as in the Y-axis direction, thereby creating the combined state of these two opposing members 111.

[0048] When the base member 110 is viewed in the Z-axis direction, the notch 114B, the end 115A and the other end 117 form rectangular openings 110A (Figure 8) at two locations on the top and bottom of the base member 110, allowing the suspension bolt B1 to be accommodated.

[0049] The configuration of the retaining member 20 and the connecting member 30 is the same as in the first embodiment.

[0050] The side portion 21 has the function of housing the anti-vibration bolt B2 in the notch portion 21A and holding it in place by sandwiching it between the side portion 21 and the flat plate portion 112.

[0051] The bolts 31 are inserted into openings 112A, 113A, and 20B and extend perpendicularly to the flat plate portion 112.

[0052] The spring 33 is a metal helical spring located between the flat plate portion 112 and the retaining member 20, and in contact with both the flat plate portion 112 and the retaining member 20. The spring 33 is arranged to surround the outer circumference of the bolt 31.

[0053] The spring 33, through its own elastic force, applies a biasing force to the retaining member 20 toward the nut 32, and has the function of holding the retaining member 20 between itself and the nut 32. In addition, the spring 33 biases the flat plate portion 112 toward the flat plate portion 113 and the head of the bolt 31, preventing the flat plate portion 112 from moving unexpectedly.

[0054] The base member 110 can be deformed between an open state where the two ends 117 are separated from each other (Figure 9) and a held state where the two ends 117 are close together and the suspension bolt B1 can be held (Figure 8) by swinging the opposing member 111 around the contact point with the bolt 31. When no external force is acting, the holding state of the base member 110 is maintained by the biasing force of the spring 33.

[0055] (work) The process of connecting the suspension bolt B1 and the anti-vibration bolt B2 using the above-mentioned connector 100 will be described below.

[0056] First, the worker grasps the two ends 116 and applies force to bring them closer together, as shown by the white arrows in Figure 9. Against the biasing force of the spring 33, the base member 110 deforms, and the overlapping flat plates 112 and 113 separate, while the abutted ends 117 separate from each other. The bolt 31 slides through the opening 113A in the direction of the long axis of the opening. As a result, a portion of the opening 110A is opened to the outside.

[0057] The worker keeps the foundation member 110 open and passes the suspension bolts B1 through the openings 110A at two locations on the top and bottom of the foundation member 110, specifically between the end 117 and the notch 114B, and between the end 117 and the end 115A.

[0058] When the worker releases their hand from end 116, the restoring force of the spring 33 causes the flat plate portions 112 and 113 to move closer together, and the opposing ends 117 also move closer to each other. The ends 117 are brought together, and the opening 110A is closed, creating a holding state. The notch 114B and end 115A hold the suspension bolt B1 by sandwiching and pressing the outer circumference of the suspension bolt B1 between themselves and end 117 (Figures 6 and 8).

[0059] Furthermore, by pressing the end portion 116 again, the worker can release the pressure on the notch 114B and the end portion 115A against the suspension bolt B1, and make adjustments such as shifting the holding position of the suspension bolt B1 up or down.

[0060] Next, the worker rotates the holding member 20 around the bolt 31, adjusting the angle so that the side portion 21 is perpendicular to the anti-vibration bolt B2.

[0061] The worker inserts the anti-vibration bolt B2 into the notch 21A and rotates the nut 32 to tighten it, thereby fixing the anti-vibration bolt B2 to the connector 100. When the nut 32 is tightened, the nut 32, the retaining member 20, and the spring 33 move against the biasing force and approach the flat plate portions 112 and 113. As a result, the anti-vibration bolt B2 is sandwiched and fixed between the side portion 21 and the flat plate portion 112 (Figure 6).

[0062] <Third Embodiment> The connector 200 according to the third embodiment will be described below with reference to Figures 10 to 13. Configurations similar to those in the first or second embodiment will be given the same reference numerals as in the first or second embodiment, and their descriptions will be omitted.

[0063] The connector 200 comprises a base member 210, two holding members 20, and two connecting members 30.

[0064] The base member 210 has two opposing members 211 of the same shape and a shaft 218, and is constructed by joining the two opposing members 211 on the shaft 218 so that they can swing.

[0065] The opposing member 211 is a member formed by bending a metal plate, and mainly has flat plate portions 212 and 213 formed in a substantially rectangular flat plate shape as shown in Figure 11, intermediate portions 214 and 215, an end portion 216, and an end portion 217 corresponding to the end of the flat plate portion 212.

[0066] The flat plate portions 212 and 213 extend in directions perpendicular to each other. An opening 212A into which the connecting member 30 is inserted is formed in the center of the flat plate portion 212. Similarly, an opening 213A into which the connecting member 30 is inserted is formed in the center of the flat plate portion 213. The opening 212A is an elongated hole having a minor axis in the vertical direction and a major axis in the horizontal direction.

[0067] The flat plate portion 212 has horizontally extending sides 212B and 212C. The flat plate portion 213 also has a horizontally extending side 213B. A projection 213D is formed on the surface of the flat plate portion 213 facing the flat plate portion 212, which can hold the connecting member 30 in a non-rotatable manner.

[0068] The intermediate section 214 connects sides 212B and 213B and is a flat plate-shaped member that extends in a substantially horizontal direction. The intermediate section 214 is formed in a substantially rectangular shape when viewed in the Z-axis direction.

[0069] A circular through-hole 214C is formed in the intermediate section 214, into which a shaft 218 is inserted. The shaft 218 supports the intermediate section 214 so that it can swing.

[0070] A notch 214B is formed in the intermediate portion 214 by two sides extending perpendicularly to each other. The notch 214B has the function of pressing and holding the outer circumference of the suspension bolt B1.

[0071] The intermediate portion 215 is a flat plate-shaped member extending substantially horizontally from the side 212C. The intermediate portion 215 is formed in a substantially rectangular shape when viewed in the Z-axis direction. An end portion 215A is formed at the end of the intermediate portion 215, extending perpendicularly to the flat plate portion 212.

[0072] A through hole 215C is formed in the intermediate section 215, into which a shaft 218 is inserted. The shaft 218 supports the intermediate section 215 so that it can swing.

[0073] The end portion 216 is a member that extends in the Z-axis direction and is formed to protrude from the end of the flat plate portion 212. When viewed in the Z-axis direction, the end portion 216 extends at an angle of approximately 45 degrees with respect to the X and Y axes. In this embodiment, the end portion 216 is formed in a flat plate shape. The shape of the end portion 216 is not limited to this embodiment and various shapes can be adopted.

[0074] The end portion 217 is located at the end of the flat plate portion 212 and extends in the Z-axis direction. The end portion 217 faces the notch portion 214B. The end portion 217 has a plurality of projections 217A. The projections 217A are formed to fit into and hook into the threaded grooves of the suspension bolt B1.

[0075] The shaft 218 is a substantially cylindrical member extending in the Z-axis direction. The shaft 218 is inserted into through holes 214C and 215C so as to pass through both the intermediate sections 214 and 215. The shaft 218 pivotably supports the intermediate sections 214 and 215.

[0076] The base member 210 is formed by combining two opposing members 211 so that their ends 217 abut against each other. More specifically, the top and bottom of one of the opposing members 211 are reversed, the ends 217 of both members are abutted against each other, and a section is created where the flat plate section 212 and the flat plate section 213 overlap in the X-axis direction, as well as a section where they overlap in the Y-axis direction, thereby creating the combined state of these two opposing members 211.

[0077] When the base member 210 is viewed in the Z-axis direction, the notch 214B, the end 215A and the other end 217 form rectangular openings 210A at two locations, upper and lower, on the base member 110, allowing the suspension bolts B1 to be accommodated.

[0078] The configuration of the retaining member 20 and the connecting member 30 is the same as in the first embodiment.

[0079] The side portion 21 has the function of housing the anti-vibration bolt B2 in the notch portion 21A and holding it in place by sandwiching it between the side portion 212 and the flat plate portion 212.

[0080] The bolt 31 is inserted into the openings 212A, 213A, and 20B and extends perpendicularly to the flat plate portion 213. The bolt 31 is male threaded. The head of the bolt 31 is housed between the projections 213D and is held non-rotatably by the projections 213D.

[0081] The spring 33 is positioned between the flat plate portion 212 and the retaining member 20, and is in contact with both the flat plate portion 212 and the retaining member 20. The spring 33 has the function of holding the retaining member 20 between itself and the nut 32 by applying a biasing force toward the retaining member 20 toward the nut 32 through its own elastic force. In addition, the spring 33 biases the flat plate portion 212 toward the flat plate portion 213 and the head of the bolt 31, preventing the flat plate portion 212 from moving unexpectedly.

[0082] The base member 210 can be deformed between an open state where the two ends 217 are separated from each other (Figure 13) and a held state where the two ends 217 are close together and the suspension bolt B1 can be held (Figure 12) by swinging the opposing member 211 around the shaft 218. When no external force is acting, the holding state of the base member 210 is maintained by the biasing force of the spring 33.

[0083] (work) The process of connecting the suspension bolt B1 and the anti-vibration bolt B2 using the above-mentioned connector 200 will be described below.

[0084] First, the worker grasps the two ends 216 and applies force to bring them closer together, as shown by the white arrows in Figure 13. Against the biasing force of the spring 33, the base member 210 deforms and opens, separating the overlapping flat plates 212 and 213, and the abutted ends 217 also separate. The bolt 31 slides through the opening 212A in the direction of the long axis of the opening. As a result, a portion of the opening 210A is opened to the outside.

[0085] The worker keeps the foundation member 210 open and passes the suspension bolts B1 through the openings 210A at two locations on the top and bottom of the foundation member 210, specifically between the end 217 and the notch 214B, and between the end 217 and the end 215A (Figure 12).

[0086] When the worker releases their hand from end 216, the restoring force of the spring 33 causes the flat plate portions 212 and 213 to move closer together, and the opposing ends 217 also move closer to each other. The ends 217 are brought together, and the opening 210A is closed. The notch 214B and end 215A hold the suspension bolt B1 by sandwiching and pressing the outer circumference of the suspension bolt B1 between themselves and end 217.

[0087] Furthermore, by pressing the end portion 216 again, the worker can release the pressure on the notch 214B and the end portion 215A against the suspension bolt B1, and make adjustments such as shifting the holding position of the suspension bolt B1 up or down.

[0088] Next, the worker rotates the holding member 20 around the bolt 31, adjusting the angle so that the side portion 21 is perpendicular to the anti-vibration bolt B2.

[0089] The worker inserts the anti-vibration bolt B2 into the notch 21A and rotates the nut 32 to tighten it, thereby fixing the anti-vibration bolt B2 to the connector 200. When the nut 32 is tightened, the nut 32 and the retaining member 20 move against the biasing force of the spring 33, moving closer to the flat plate portions 212 and 213. As a result, the anti-vibration bolt B2 is sandwiched and fixed between the side portion 21 and the flat plate portion 212 (Figure 10).

[0090] <Fourth Embodiment> The connector 300 according to the fourth embodiment will be described below with reference to Figures 14 to 17. Configurations similar to those in the first to third embodiments will be given the same reference numerals as those embodiments, and their descriptions will be omitted.

[0091] The connector 300 comprises a base member 310 and two connecting members 330.

[0092] The base member 310 has two opposing members 311 of the same shape, and is constructed by combining the two opposing members 311 so that they can swing.

[0093] The opposing member 311 is a member formed by bending a metal plate, and as shown in Figure 15, it has a flat plate portion 312, 313 formed in a substantially rectangular flat plate shape, an intermediate portion 314, 315, an end portion 316, an end portion 317 located at the end of the flat plate portion 312, and a holding member 320.

[0094] The flat plate portions 312 and 313 extend in directions perpendicular to each other. An opening 312A is formed in the center of the flat plate portion 312 into which the connecting member 330 is inserted. The opening 312A is an elongated hole with a short axis in the vertical direction and a long axis in the horizontal direction. Similarly, an opening 313A is formed in the center of the flat plate portion 313 into which the connecting member 330 is inserted. The edge of the opening 313A is threaded, and the connecting member 30 is screwed into it.

[0095] The flat plate portion 312 has sides 312B and 312C that extend horizontally. The flat plate portion 313 also has a side 313B that extends horizontally.

[0096] The intermediate portion 314 connects sides 312B and 313B and is a flat plate-shaped member that extends in a substantially horizontal direction. The intermediate portion 314 has an edge portion 314A that extends in a direction of approximately 45 degrees with respect to the X and Y axes.

[0097] A notch 314B is formed in the center of the intermediate portion 314 to guide the suspension bolt B1 and to press and hold the outer circumference of the suspension bolt B1. The notch 314B is a cutout in the intermediate portion 314 and is formed to extend from the center of the edge portion 314A toward the end portion 317 when viewed in the Z-axis direction. The notch 314B has a wider width than the suspension bolt B1, allowing the suspension bolt B1 to move within it.

[0098] The intermediate portion 315 is a flat plate-shaped member that extends substantially horizontally from side 312C. The intermediate portion 315 is formed in a substantially triangular shape when viewed in the Z-axis direction.

[0099] A notch 315B is formed in the center of the intermediate portion 315 to guide the suspension bolt B1 and to press and hold the outer circumference of the suspension bolt B1. When viewed in the Z-axis direction, the notch 315B is formed to cut out the edge of the intermediate portion 315 toward the flat plate portion 312.

[0100] The end portion 316 is a member that extends in the Z-axis direction and is formed to protrude from the end of the flat plate portion 313. When viewed in the Z-axis direction, the end portion 316 extends at an angle of approximately 45 degrees with respect to the X and Y axes. In this embodiment, the end portion 316 is formed in a flat plate shape. The shape of the end portion 316 is not limited to this embodiment and various shapes can be adopted.

[0101] The end portion 317 is located at the end of the flat plate portion 312 that faces the flat plate portion 313, and extends in the Z-axis direction.

[0102] The retaining member 320 is a portion integrally formed with the flat plate portion 312 via the end portion 317, and is formed by bending it away from the flat plate portion 312. When viewed in the Z-axis direction, the retaining member 320 and the flat plate portion 312 are formed in a U-shape.

[0103] As shown in Figures 14 to 17, the retaining member 320 has a connecting portion 322 and an opposing portion 323. The retaining member 320 has a shape that is substantially symmetrical with respect to a center line 320CL parallel to the X-axis or Y-axis. The opposing portion 323 is cantilevered by the connecting portion 322.

[0104] The opposing portion 323 is a member positioned opposite the flat plate portion 312 with a gap between them. The opposing portion 323 has a flat plate portion 3231 formed in a flat shape, and protruding portions 3232, 3233, 3234, and 3235 that protrude from the flat plate portion 3231 toward the flat plate portion 312.

[0105] The flat plate portion 3231 is a flat plate-shaped member that is parallel to the Z-axis direction and is provided opposite to the flat plate portion 312. The end of the flat plate portion 3231 is connected to the connecting portion 322.

[0106] The flat plate portion 3231 has a surface 3231B facing the flat plate portion 312 and a surface 3231A formed on the opposite side of surface 3231B.

[0107] Furthermore, an opening 323A is formed in the flat plate portion 3231, penetrating it. The opening 323A is an elongated hole that forms a major axis along the center line 320CL and a minor axis in the Z-axis direction. A connecting member 30 is inserted into the opening 323A.

[0108] Two protrusions 3232 are provided so as to be connected to the flat plate portion 3231. Each protrusion 3232 is a member formed to protrude from the Z-axis end of the flat plate portion 3231 toward the flat plate portion 312. In a view along the Z-axis, the protrusions 3232 are formed in a substantially rectangular shape.

[0109] The projection 3233 is a member formed to protrude from the surface 3231B toward the flat plate portion 312, and is formed to be substantially rectangular when viewed along the center line 320CL. The projection 3233 extends along the Z-axis, and the center of the projection 3233 coincides with the center line 320CL.

[0110] The protruding portions 3234 are members formed to protrude from the surface 3231B toward the flat plate portion 312, and are provided at four locations symmetrically with respect to the center line 320CL.

[0111] The protrusions 3234 are classified into linearly formed protrusions 3234A and arc-shaped protrusions 3234B when viewed in a direction perpendicular to the surface 3231B. The protruding lengths of protrusions 3234A and 3234B are smaller than the height of the threads of the anti-vibration bolt B2.

[0112] The protrusions 3234A and 3234B fit into the threaded grooves of the anti-vibration bolt B2 and engage with the threads when the connector 300 holds the anti-vibration bolt B2, thereby restraining the movement of the anti-vibration bolt B2. Because the protrusion 3234B is formed in an arc, the anti-vibration bolt B2 can swing along the protrusion 3234B.

[0113] The protruding portion 3235 is a member that extends perpendicularly from the flat plate portion 3231 and is formed to face the flat plate portion 312. The protruding portion 3235 is provided in two locations so as to be symmetrical with respect to the center line 320CL.

[0114] The base member 310 is formed by combining two opposing members 311 so that their ends 317 abut against each other. More specifically, the top and bottom of one of the opposing members 311 are reversed, the ends 317 of both members are abutted against each other, and a section is created where the flat plate section 312 and the flat plate section 313 overlap in the X-axis direction, as well as a section where they overlap in the Y-axis direction, thereby creating the combined state of these two opposing members 311.

[0115] Furthermore, by combining them in this way, the notches 314B and 315B face each other at two locations on the upper and lower parts of the foundation member 310, making it possible to clamp the suspension bolt B1.

[0116] The two opposing members 311 can pivot relative to each other around an axis AX that passes through the abutment portions of the two ends 317. Therefore, the base member 310 can deform between an open state where the notches 314B and 315B are separated (Figure 17(b)) and a held state where the notches 314B and 315B are brought closer together and the suspension bolt B1 can be held (Figure 17(a)). When no external force is acting, the holding state of the base member 310 is maintained by the biasing force of the spring 33.

[0117] The connecting member 330 includes a bolt 31, a washer 34 which is an annular member, and a spring 33.

[0118] The bolt 31 is inserted into openings 312A and 323A and extends perpendicularly to the flat plate portion 313. The bolt 31 is a male thread and is screwed into opening 313A of the flat plate portion 313 to join it.

[0119] The spring 33 is inserted into the opening 323A and positioned between the flat plate portion 312 and the washer 34, with both ends in contact with both the flat plate portion 312 and the washer 34. The spring 33 biases the flat plate portion 312 toward the flat plate portion 313, preventing the flat plate portion 312 from moving unexpectedly.

[0120] The washer 34 is sandwiched between the spring 33 and the head of the bolt 31.

[0121] (work) The process of connecting the suspension bolt B1 and the anti-vibration bolt B2 using the above-described connector 300 will be explained below.

[0122] First, the worker grasps the two ends 316 and applies force to bring them closer together. Against the biasing force of the spring 33, the base member 310 deforms, and as shown in Figure 17(b), the overlapping flat portions 312 and 313 separate, and the notches 314B and 315B also separate from each other, becoming open. The bolt 31 slides through the opening 323A in the direction of the long axis of the opening.

[0123] The worker keeps the foundation member 310 open and passes the suspension bolts B1 through the notches 314B and 315B at two locations on the top and bottom of the foundation member 310.

[0124] When the worker releases their hand from end 316, the restoring force of the spring 33 causes the flat plate portions 312 and 313 to move closer together, and the notches 314B and 315B also move closer to each other. The notches 314B and 315B hold the suspension bolt B1 by pressing against the outer circumference of the suspension bolt B1 (Figure 17(a)).

[0125] Next, as shown in Figure 16, the worker inserts the vibration-damping bolt B2 between the flat plate portion 312 and the holding member 320. The vibration-damping bolt B2 is passed between the protruding portion 3235 and the spring 33 and penetrates the base member 310.

[0126] After the above process, the suspension bolt B1 and the anti-vibration bolt B2 are not completely fixed to the connector 300, but are held in place by the connector 300; in other words, they are in a temporarily fixed state. In this state, the worker adjusts the position and orientation of the suspension bolt B1 and the anti-vibration bolt B2 relative to the connector 300.

[0127] More specifically, by having the worker press the end portion 316, the notches 314B and 315B can be isolated from the outer circumference of the suspension bolt B1, or the pressure on the notches 314B and 315B can be loosened. In this way, it is possible to move the suspension bolt B1 in the Z-axis direction relative to the connector 300 while maintaining the state in which the suspension bolt B1 is surrounded by the notches 314B and 315B.

[0128] The anti-vibration bolt B2 can swing along the protrusions 3234A and 3234B, as shown by the white arrows in Figure 16. By swinging the anti-vibration bolt B2, the operator can adjust the angle of the anti-vibration bolt B2 relative to the Z-axis and the connector 300. However, since the outer circumference of the anti-vibration bolt B2 is in contact with the spring 33 and the protrusion 3232, the swing of the anti-vibration bolt B2 is limited to a certain range.

[0129] Once the position and orientation of the suspension bolt B1 and the anti-vibration bolt B2 relative to the connector 300 have been adjusted, the worker performs the task of restraining or fixing the suspension bolt B1 and the anti-vibration bolt B2 by holding them immovably relative to the connector 300.

[0130] Specifically, the worker uses a tool to tighten the bolt 31. As the bolt 31 is tightened, the head of the bolt 31 contacts and presses against the surface 3231A via the washer 34. As a result, the opposing portion 323 moves closer to the flat plate portion 312, and the retaining member 320 deforms.

[0131] As the deformation of the retaining member 320 progresses and the opposing portion 323 moves until it is almost parallel to the flat plate portion 312, the tips of the protruding portions 3232 and 3233 come into contact with the flat plate portion 312. When this contact occurs, the opposing portion 323 can no longer approach the flat plate portion 312, and further deformation of the retaining member 320 becomes impossible. This prevents excessive tightening of the bolt 31 and the resulting excessive deformation or breakage of the retaining member 320.

[0132] As a result of tightening bolt 31, the anti-vibration bolt B2 is restrained and fixed so that it cannot move in any direction, as its outer circumference is sandwiched and pressed between surface 3231B and flat plate portion 312. The protrusions 3234A and 3234B fit into the thread grooves of the anti-vibration bolt B2 and engage with the threads, thereby restraining the anti-vibration bolt B2 so that it cannot move in the bolt axis direction.

[0133] Furthermore, the suspension bolt B1 is fixed in place so that it cannot move in any direction, as its outer circumference is sandwiched and pressed between the notches 314B and 315B.

[0134] Since the retaining member 320 is formed symmetrically with respect to the center line 320CL, the anti-vibration bolt B2 can be inserted between the retaining member 320 and the flat plate portion 312 from both above and below. Therefore, workers do not need to reverse the orientation of the connector 300 during installation, and can proceed with the work easily.

[0135] <Fifth Embodiment> The connector 400 according to the fifth embodiment will be described below with reference to Figures 18 to 22. Configurations similar to those of the first to fourth embodiments will be given the same reference numerals as those embodiments and will not be described further.

[0136] The connector 400 comprises a base member 410 and two connecting members 430.

[0137] The base member 410 has two opposing members 411 of the same shape, and is constructed by combining the two opposing members 411 so that they can swing together.

[0138] The opposing member 411 is a member formed by bending a metal plate, and mainly as shown in Figure 19, it has a flat plate portion 412 formed in a substantially rectangular flat plate shape, intermediate portions 414 and 415, an end portion 416, an end portion 417 corresponding to the end of the flat plate portion 412, and a holding member 420.

[0139] An opening 412A is formed in the center of the flat plate portion 412 into which a connecting member 430 is inserted. The opening 412A is a through hole with a roughly circular diameter. Female threads are cut into the edge of the opening 412A, into which the connecting member 430 is screwed. The flat plate portion 412 has a side 412B that extends in the horizontal direction.

[0140] The intermediate portion 414 connects the edge 412B and the retaining member 420 and is a flat plate-shaped member that extends in a substantially horizontal direction. The intermediate portion 414 has an edge portion 414A that extends in a direction of approximately 45 degrees with respect to the X and Y axes.

[0141] A notch 414B is formed in the center of the intermediate portion 414 to guide the suspension bolt B1 and to press and hold the outer circumference of the suspension bolt B1. The notch 414B is a cutout in the intermediate portion 414 and is formed to extend from the center of the edge portion 414A toward the end portion 417 when viewed in the Z-axis direction. The notch 414B has a wider width than the suspension bolt B1, allowing the suspension bolt B1 to move within it.

[0142] The intermediate portion 415 is a flat plate-shaped member that extends substantially horizontally from the lower part of the retaining member 420. A notch 415B is formed in the center of the intermediate portion 415 to guide the suspension bolt B1 and to press and hold the outer circumference of the suspension bolt B1. When viewed in the Z-axis direction, the notch 415B is formed so as to cut out the edge of the intermediate portion 415 toward the retaining member 420.

[0143] The end portion 416 is a member that extends in the Z-axis direction and is formed to protrude from the end of the flat plate portion 412. When viewed in the Z-axis direction, the end portion 416 extends at an angle of approximately 45 degrees with respect to the X and Y axes. In this embodiment, the end portion 416 is formed in a flat plate shape. The shape of the end portion 416 is not limited to this embodiment and various shapes can be adopted.

[0144] End portion 417 corresponds to the end of the flat plate portion 412 and is a portion that extends in the Z-axis direction. End portion 417 is located on the opposite side of end portion 416 in the flat plate portion 412.

[0145] The retaining member 420 is a flat plate-shaped portion integrally formed with the flat plate portion 412 via the intermediate portion 414, and extends in a direction intersecting the direction in which the flat plate portion 412 extends.

[0146] The retaining member 420 has a shape that is substantially symmetrical with respect to a center line 420CL parallel to the X-axis or Y-axis.

[0147] The holding member 420 has a flat plate portion 421 formed in a flat plate shape and protruding portions 422, 423, and 424 that protrude from the flat plate portion 421.

[0148] The flat plate portion 421 is not positioned parallel to the X or Y axis, but rather is positioned to form a slight angle when viewed in the Z direction. The flat plate portion 421 has a surface 421B facing the flat plate portion 412 and a surface 421A formed on the opposite side of surface 421B.

[0149] Furthermore, an opening 420A is formed in the flat plate portion 421, penetrating it. The opening 420A is an elongated hole that forms a major axis along the center line 420CL and a minor axis in the Z-axis direction. A connecting member 430 is inserted into the opening 420A.

[0150] The projection 422 extends perpendicularly from the surface 421B. Two projections 422 are formed symmetrically with respect to the center line 420CL, and each extends in a direction intersecting the Z-axis.

[0151] The projection 423 is a member formed to protrude perpendicularly to the surface 421B, and is formed to be substantially rectangular when viewed along the center line 420CL. The projection 423 extends along the Z-axis, and the center of the projection 423 coincides with the center line 420CL.

[0152] The protruding portion 424 is a member formed to protrude perpendicularly from the surface 421B, and is provided at four locations symmetrically with respect to the center line 420CL.

[0153] The protrusions 424 can be classified into linearly formed protrusions 424A and arc-shaped protrusions 424B when viewed in a direction perpendicular to the surface 421B. The protruding lengths of the protrusions 424A and 424B are smaller than the height of the threads of the anti-vibration bolt B2.

[0154] The protrusions 424A and 424B fit into the threaded grooves of the anti-vibration bolt B2 and engage with the threads when the connector 400 holds the anti-vibration bolt B2, thereby restraining the movement of the anti-vibration bolt B2. Because the protrusion 424B is formed in an arc, the anti-vibration bolt B2 can swing along the protrusion 424B.

[0155] The base member 410 is formed by combining two opposing members 411 so that their ends 417 abut against each other. More specifically, the top and bottom of one of the opposing members 411 are reversed, the ends 417 of both members abut against each other, and the flat plate portion 412 and the flat plate portion 421 are positioned opposite each other in the X-axis direction, as well as in the Y-axis direction, thus creating the combined state of these two opposing members 411.

[0156] Furthermore, by combining them in this way, the notches 414B and 415B face each other at two locations, the upper and lower parts of the foundation member 410, making it possible to clamp the suspension bolt B1.

[0157] The two opposing members 411 can pivot relative to each other around an axis AX (Figure 21(b)) that passes through the abutment portion of the end portion 417. Therefore, the base member 410 can deform between an open state where the notches 414B and 415B are separated and a held state where the notches 414B and 415B are brought closer together and the suspension bolt B1 can be held (as shown in Figure 21 and other figures). When no external force is acting, the holding state of the base member 410 is maintained by the biasing force of the spring 33.

[0158] The connecting member 430 includes a bolt 31, a washer 34 which is an annular member, and a spring 33.

[0159] The bolt 31 is inserted into openings 412A and 420A and extends perpendicularly to the flat plate portion 412. The bolt 31 is a male thread and is screwed into opening 412A of the flat plate portion 412 to join it.

[0160] The spring 33 is positioned between the surface 421A and the washer 34, with both ends contacting the flat plate portion 421 and the washer 34, respectively. The spring 33 biases the flat plate portion 421 toward the opposing flat plate portion 412, preventing the flat plate portion 421 from moving unexpectedly.

[0161] The washer 34 has a bolt 31 inserted through its through hole, and is also sandwiched between the spring 33 and the head of the bolt 31.

[0162] (work) The process of connecting the suspension bolt B1 and the anti-vibration bolt B2 using the above-mentioned connector 400 will be described below.

[0163] First, the worker grasps the two ends 416 and applies force to bring them closer together. Against the biasing force of the spring 33, the opposing members 411 swing relative to each other around the end 417 as an axis, and the base member 410 deforms. The bolt 31 slides through the opening 420A in the direction of the long axis of the opening. At this time, the opposing flat plate portions 412 and 421 separate, and the notches 414B and 415B also separate from each other, creating an open state.

[0164] The worker keeps the foundation member 410 open and passes the suspension bolts B1 through the notches 414B and 415B at two locations on the top and bottom of the foundation member 410.

[0165] When the worker releases their hand from end 416, the restoring force of the spring 33 causes the opposing flat plate portions 412 and 421 to move closer together, and the notches 414B and 415B also move closer to each other. The notches 414B and 415B hold the suspension bolt B1 by pressing against its outer circumference (see Figure 21 and other figures).

[0166] Next, the worker inserts the vibration-damping bolt B2 between the flat plate portion 412 and the holding member 420. As shown in Figures 18 and 20, the vibration-damping bolt B2 is passed between the protruding portion 422 and the bolt 31.

[0167] After the above process, the suspension bolt B1 and the anti-vibration bolt B2 are not completely fixed to the connector 400, but are held in place by the connector 400; in other words, they are in a temporarily fixed state. In this state, the worker adjusts the position and orientation of the suspension bolt B1 and the anti-vibration bolt B2 relative to the connector 400.

[0168] More specifically, by having the worker press the end portion 416, the notches 414B and 415B can be isolated from the outer circumference of the suspension bolt B1, or the pressure on the notches 414B and 415B can be loosened. In this way, it is possible to move the suspension bolt B1 in the Z-axis direction relative to the connector 400 while maintaining the state in which the suspension bolt B1 is surrounded by the notches 414B and 415B.

[0169] The anti-vibration bolt B2 can swing along the protrusions 424A and 424B, as shown by the white arrows in Figure 20. By swinging the anti-vibration bolt B2, the operator can adjust the angle of the anti-vibration bolt B2 relative to the Z-axis and the connector 400. However, since the outer circumference is in contact with the bolt 31 and the protrusions 422 and 423, the swing of the anti-vibration bolt B2 is limited to a certain range.

[0170] Once the position and orientation of the suspension bolt B1 and the anti-vibration bolt B2 relative to the connector 400 have been adjusted, the worker performs the task of restraining or fixing the suspension bolt B1 and the anti-vibration bolt B2 by holding them immovably relative to the connector 400.

[0171] Specifically, the worker uses a tool to tighten the bolt 31. As the bolt 31 is tightened, the spring 33, which is pressed against the head of the bolt 31, presses against the surface 421A. As a result, the flat plate portion 421 moves closer to the opposing flat plate portion 412.

[0172] As the flat plate portion 421 moves and becomes nearly parallel to the flat plate portion 412, the tips of the protruding portions 422 and 423 come into contact with the flat plate portion 412. When this contact occurs, the flat plate portion 421 can no longer approach the flat plate portion 412. This prevents excessive tightening of the bolt 31 and the resulting excessive deformation or breakage of the retaining member 420.

[0173] As a result of tightening bolt 31, the anti-vibration bolt B2 is restrained and fixed so that it cannot move in any direction, as its outer circumference is sandwiched and pressed between surface 421B and flat plate portion 412. The protrusions 424A and 424B fit into the thread grooves of the anti-vibration bolt B2 and engage with the threads, thereby restraining the anti-vibration bolt B2 so that it cannot move in the bolt axis direction.

[0174] Furthermore, the suspension bolt B1 is fixed in place so that it cannot move in any direction, as its outer circumference is sandwiched and pressed between the notches 414B and 415B.

[0175] Since the retaining member 420 is formed symmetrically with respect to the center line 420CL, the vibration-preventing bolt B2 can be inserted between the retaining member 420 and the flat plate portion 412 from both above and below. Therefore, workers do not need to reverse the orientation of the connector 400 during installation, and can proceed with the work easily.

[0176] <Effects> The following embodiments are described for each of the above embodiments.

[0177] (Aspect 1) The connectors 1, 100, 200, 300, and 400 connect a rod-shaped suspension bolt B1 and a rod-shaped anti-vibration bolt B2 extending in a direction intersecting the suspension bolt B1. The connectors 1, 100, 200, 300, and 400 include base members 10, 110, 210, 310, and 410 that swing between a holding state that holds the suspension bolt B1 and an open state that releases the holding state, and holding members 20, 320, and 420 that are connected to the base members 10, 110, 210, 310, and 410 and hold the anti-vibration bolt B2 by pressing the outer circumference of the anti-vibration bolt B2.

[0178] In the above configuration, the suspension bolts B1 can be easily connected by swinging the base members 10, 110, 210, 310, and 410, resulting in high work efficiency.

[0179] (Aspect 2) In aspect 1, the holding members 20, 320, and 420 each have two holding members 20, 320, and 420, and each of the two holding members 20, 320, and 420 is connected to the base members 10, 110, 210, 310, and 410 and holds the anti-vibration bolt B2 by pressing the outer circumference of the anti-vibration bolt B2.

[0180] In the above configuration, the anti-vibration bolt B2 is held by the two retaining members 20, 320, and 420, so the anti-vibration bolt B2 can be firmly restrained and fixed.

[0181] (Aspect 3) In aspect 1 or 2, the base members 10, 110, 210, 310, 410 each have two opposing members 11, 111, 211, 311, 411, and the two opposing members 11, 111, 211, 311, 411 swing relative to each other.

[0182] In the above configuration, the suspension bolt B1 can be easily connected by swinging the two opposing members 11, 111, 211, 311, and 411, resulting in high work efficiency.

[0183] (Aspect 4) In any of aspects 1 to 3, the abutting portions of the two opposing members 111, 311, and 411 form an axis AX extending parallel to the suspended bolt B1 in the holding state, and the opposing members 111, 311, and 411 swing relative to each other around axis AX.

[0184] In the above configuration, oscillation is achieved using the abutment portion without the use of additional components, thus enabling oscillation with a simple structure.

[0185] (Aspect 5) In any of aspects 1 to 4, the two opposing members 211 are connected and the suspension bolt B1 in the holding state is further provided with a shaft 218 that extends parallel to it, and the two opposing members 211 swing relative to each other around the shaft 218.

[0186] In the above configuration, the two opposing members 211 are connected using the shaft 218, thereby achieving stable oscillating motion.

[0187] (Aspect 6) In any of aspects 1 to 5, the opposing members 11, 111, 211, 311, 411 have flat plate portions 12, 112, 212, 312, 412 (corresponding to the first and second support portions) that face the holding members 20, 320, 420 and press against and hold the outer circumference of the anti-vibration bolt B2, and intermediate portions 14, 114, 214, 314, 414 (corresponding to the first intermediate portion) and intermediate portions 15, 115, 215, 315, 415 (corresponding to the second intermediate portion) that extend in a direction intersecting the flat plate portions 12, 112, 212, 312, 412, and in the holding state, the outer circumference of the suspension bolt B1 is held sandwiched between the intermediate portions 14, 114, 214, 314, 414 and the intermediate portions 15, 115, 215, 315, 415.

[0188] In the above configuration, the suspension bolt B1 and the anti-vibration bolt B2 can be connected by a simple configuration of flat plate sections 12, 112, 212, 312, and 412 and first and second intermediate members.

[0189] (Aspect 7) In any of aspects 1 to 6, the holding members 20, 320, and 420 are connected to the base members 10, 110, 210, 310, and 410 such that they can swing around an axis perpendicular to a plane parallel to both the suspension bolt B1 in the holding state and the anti-vibration bolt B2 held by the holding members 20, 320, and 420.

[0190] In the above configuration, by swinging the holding members 20, 320, and 420, the direction can be easily aligned with the anti-vibration bolt B2, and the anti-vibration bolt B2 can be held in place.

[0191] (Aspect 8) In any of aspects 1 to 7, the holding members 320 and 420 are connected to the base members 310 and 410 in such a way that they are unable to swing around an axis perpendicular to a plane parallel to both the suspended bolt B1 in its held state and the anti-vibration bolt B2 held by the holding members 320 and 420.

[0192] In the above configuration, loosening and displacement of the retaining members 320 and 420 are prevented. Therefore, even if the connector 1 is shaken violently by an earthquake or the like, the restraint and fixation of the suspension bolt B1 and the anti-vibration bolt B2 are maintained.

[0193] (Aspect 9) In any of aspects 1 to 8, the opposing members 11, 111, 211, 311 have a first support portion and a second support portion that face the holding members 20, 320 and press against and hold the outer circumference of the anti-vibration bolt B2, and flat plate portions 13, 113, 213, 313 (corresponding to the first base portion and second base portion) that extend in a direction perpendicular to the first support portion, and in the holding state, the first support portion and the flat plate portions 13, 113, 213, 313 overlap, and the second support portion and the flat plate portions 13, 113, 213, 313 overlap.

[0194] In the above configuration, the range of oscillation can be limited by overlapping the base and the support. The shapes of the base members 10, 110, 210, and 310 in the holding state can be determined with a simple configuration without using additional members.

[0195] (Aspect 10) In any of aspects 1 to 9, the spring 33 applies a biasing force to the base members 10, 110, 210, 310, and 410, thereby suppressing oscillation.

[0196] In the above configuration, loosening and displacement of the base members 10, 110, 210, 310, and 410 are prevented. Therefore, even if the connecting device 1 is shaken violently by an earthquake or the like, the restraint and fixation of the suspension bolt B1 and the anti-vibration bolt B2 are maintained.

[0197] (Aspect 11) In any of aspects 1 to 10, the two opposing members 11, 111, 211, 311, and 411 have the same shape.

[0198] In the above configuration, by using components of the same shape, the number of parts can be reduced, resulting in a simpler structure. This can lower the cost of manufacturing the product. [Explanation of Symbols]
