[Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-203774 Summary of the Invention [Problem to be solved by the invention]
[0004] The fixing mechanism is a plate-shaped member, one horizontal end of which is supported on the guide rail by a rail clip, and the other horizontal end of which protrudes like a cantilever from the support provided by the guide rail, with a lock bar insertion hole provided in this protrusion. Therefore, the fixing mechanism is subjected to a rotational moment due to the weight of the elevator car. The rail clip absorbs the rotational moment acting on the fixing mechanism through a frictional holding force acting on the contact point with the fixing mechanism. The frictional holding force of the rail clip has a limit, and if the magnitude of the rotational moment acting on the fixing mechanism exceeds the frictional holding force of the rail clip, slippage will occur between the rail clip and the fixing mechanism, and the fixing mechanism will no longer be able to maintain its reliability as a fastener for securing the elevator car.
[0005] Hereinafter, the elevator car, locking bar, and fixing mechanism will be referred to as the car, stopper pin, and fixing member, respectively, and the device that fixes the car at the height position where maintenance work is performed will be referred to as the car fixing device.
[0006] An object of the present invention is to provide an elevator device in which slippage occurring between a rail clip and a fixing member due to a rotational moment acting on the fixing member in a car fixing device can be suppressed. [Means for solving the problem]
[0007] In order to achieve the above object, the elevator device of the present invention comprises: a fixing section which is fixed to the car guide rail and which includes a fixing member provided with a through hole, a first clamping member which clamps the fixing member from a side of the car guide rail, and a second clamping member which clamps the fixing member from a side opposite to the first clamping member; a stopper pin operating mechanism unit provided on the car of the passenger car, the stopper pin being inserted into the through hole, The aforementioned A car The aforementioned Car fixing device that fixes the car to the car guide rail Equipped with In the elevator device The car guide rail has a guide rail fixing portion fixed to a hoistway wall side, and a guide portion erected from the guide rail fixing portion and guiding the car, the guide rail fixing portion has a surface on which the guide portion is provided, a back surface on which the fixing member is fixed, and a side surface formed between the surface and the back surface, The second clamping member Guide rail fixing part of The aforementioned It has a contact portion that contacts the side surface. [Effects of the Invention]
[0008] According to the present invention, in the car fixing device for an elevator system, the abutment portion of the second clamping member abuts against the side surface of the car guide rail, thereby suppressing rotation of the fixing member due to rotational moment and suppressing slippage between the rail clip and the fixing member, thereby firmly fixing the fixing member to the guide rail.

[0011] 1 to 12, an embodiment of an elevator apparatus 100 and a car fixing device 1 of the present invention will be described below. In each drawing, the same components are assigned the same reference numerals, and repeated explanations will be omitted. In the following description, the up-down direction (vertical direction) corresponds to the ascending and descending direction of the car 104, and the horizontal direction is defined as the direction along the width direction of the guide rail 106 to which the car fixing device 1 is fixed.
[0012] The configuration of an elevator system 100 will be described with reference to Fig. 1. Fig. 1 is a schematic diagram of an elevator system 100 according to an embodiment of the present invention.
[0013] The elevator device 100 includes a car 104, a counterweight 105, a hoist 103, a car guide rail 106, a counterweight guide rail 108, a control device (elevator control device) 102, and a car fixing device 1.
[0014] The car 104 and the counterweight 105 are provided inside a hoistway 101 provided in a building, and are suspended in a bucket-like manner by a main rope (not shown) wound around a hoisting machine 103. The car 104 and the counterweight 105 are connected by the main rope.
[0015] The main rope (not shown) is wound around a hoist 103 , and the hoist 103 operates the main rope to raise and lower a car 104 and a counterweight 105 within the elevator shaft 101 .
[0016] The car guide rails 106 and the counterweight guide rails 108 extend in the up-down direction (vertical direction) within the hoistway 101 and are fixed to the hoistway wall 101a by rail brackets 111. The car guide rails 106 guide the elevator car 104 as it moves up and down. The counterweight guide rails 108 guide the counterweight 105 as it moves up and down.
[0017] The control device 102 controls the lifting and lowering operation of the elevator device 100. To this end, the control device 102 controls the driving of the hoisting machine 103.
[0018] The car fixing device 1 is a device for positioning and fixing the car top (top surface) 104a of the car 104 at a specific floor where the hoist 103 and the control device 102 are located when performing work such as inspection or repair of the hoist 103 and the control device 102, and is installed on the car top 104a of the car 104.
[0019] 1 and 2, automatic adjustment of the car position during maintenance work on the elevator system 100 will be described. Fig. 2 is a schematic diagram showing the elevator system 100 according to one embodiment of the present invention, in a state where the car 104 is positioned and stopped at a predetermined position during maintenance work on the control device 102.
[0020] In the elevator system 100 of this embodiment, the hoisting machine 103 and the control device 102 are arranged on a specific floor at a height position equal to or higher than the floor level 1FL of the lowest floor plus the height He of one floor. The specific floor is a floor on which the hoisting machine 103 and the control device 102 are installed, and may be referred to as the installation floor of the hoisting machine 103 and the control device 102, or simply as the installation floor. Note that Figure 2 illustrates an example in which the hoisting machine 103 and the control device 102 are installed on the second floor, and the specific floor (installation floor) is the second floor.
[0021] When inspecting or repairing the hoist 103 and the control device 102, the car top (top surface) 104a of the car 104 is positioned at floor level 2FL of the second floor, which is a specific floor, and a worker performs the work on the car top 104a of the car 104. That is, in this embodiment, the car top 104a of the car 104 serves as a foothold for the worker. For this purpose, the worker gets on to the car top 104a from the landing floor.
[0022] When a worker boards from the landing floor to the car top 104a, the car top 104a of the car 104 is positioned to coincide with the floor level of the boarding floor. For example, if the boarding floor is the first floor, the car top 104a of the car 104 is positioned at floor level 1FL of the first floor. In this case, the car top 104a does not need to coincide with the floor level 1FL of the boarding floor, as long as it is positioned inside the range ΔH within which the worker can board.
[0023] Once the car top (top surface) 104a of the car 104 has been positioned at floor level 2FL of the second floor, which is a specific floor, the car 104 is fixed by a car fixing device 1 (see FIG. 3) described below. When work is performed on the car top 104a, a handrail 104b is installed on the car top 104a. The handrail 104b is stored in a folded state on the car top 104a, and is unfolded onto the car top 104a during work.
[0024] The car fixing device 1 will be described with reference to Fig. 3. Fig. 3 is a perspective view showing a schematic configuration of the car fixing device 1 according to one embodiment of the present invention.
[0025] The car fixing device 1 is operated by a worker who gets on the car top 104a from the car top 104a, thereby fixing the car 104 to the guide rail 106. For this purpose, the car fixing device 1 is provided on the car top 104a.
[0026] The car fixing device 1 is configured to include a fixing part 2 having a fixing member 22 with a through hole 221 formed therein, and a stopper pin operating mechanism part 3 having a stopper pin 31 inserted into the through hole 221.
[0027] The fixing section 2 has a fixing member 22 made up of a plate-like member. The fixing member 22 in Fig. 3 is L-shaped and is configured to have a horizontal extension portion 222 that extends horizontally and a vertical extension portion 223 that extends vertically. This shape of the fixing member 22 improves the degree of freedom in the arrangement of the stopper pin operating mechanism 3 that has the stopper pin 31, and increases the degree of freedom in the design of the car 104 and the car fixing device 1.
[0028] One horizontal end of the horizontally extending portion 222 constitutes the fixed support portion 22a that is fixed to and supported by the car guide rail 106. As will be described with reference to Figures 7 and 8, the fixed support portion 22a is fixed to the car guide rail 106 using rotation suppressing members 21A and 21B, a rail clip 23, and fasteners 24 and 25. For this reason, the rotation suppressing members 21A and 21B, the rail clip 23, and the fasteners 24 and 25 can be considered to be components that constitute the fixed portion 2 together with the fixing member 22.
[0029] The vertically extending portion 223 is provided to extend downward from the other horizontal end portion of the horizontally extending portion 222. A through-hole 221 is provided in the vertically extending portion 223. The through-hole 221 is located below the fixed support portion 22a.
[0030] The through-hole 221 of the fixing member 22 constitutes an insertion hole (stopper pin insertion hole) through which the stopper pin 31 is inserted. The stopper pin 31 is a locking member that is locked to the fixing member 22 of the fixing part 2, and the stopper pin insertion hole 221 is a locking part in which the stopper pin 31 is locked.
[0031] The stopper pin operating mechanism 3 will be described with reference to Figures 4, 5 and 6. Figure 4 is a plan view of the car fixing device 1 according to one embodiment of the present invention as seen from above. Figure 5 is a plan view of the car fixing device 1 according to one embodiment of the present invention as seen from the side. Figure 6 is an enlarged view of part VI in Figure 4. Note that the car guide rail 106 and the fixing part 2 are not shown in Figure 5.
[0032] As shown in FIG. 4, one set of the car fixing devices 1 is provided on each side of the car 104 in the width direction W104 of the car 104.
[0033] 5, the stopper pin operating mechanism 3 has a stopper pin 31 and a stopper pin operating mechanism 32 that operates the stopper pin 31. The stopper pin 31 is assembled to the stopper pin operating mechanism 3 so as to be movable back and forth in its longitudinal direction, and the stopper pin operating mechanism 32 operates the movement of the stopper pin 31 back and forth in the longitudinal direction.
[0034] As shown in Figure 6, the stopper pin 31 is in the retracted position during normal operation of the elevator device 100, and is pushed out from the retracted position and inserted into the stopper pin insertion hole 221 (see Figure 3) during work such as inspection or repair of the hoisting machine 103 and the control device 102. 31A indicates the stopper pin 31 when it is in the retracted position, and 31B indicates the stopper pin 31 when it has advanced from the retracted position.
[0035] When the stopper pin 31 is inserted into the stopper pin insertion hole 221 and engaged with the fixing member 22 of the fixing part 2, the load of the car 104 is supported on the car guide rail 106 via the car fixing device 1, and the position of the car 104 is fixed relative to the car guide rail 106.
[0036] As shown in Fig. 6, the car guide rail 106 has a guide portion 106a that guides the car 104, and a guide rail fixing portion 106b that is fixed to the elevator shaft wall 101a (see Fig. 1). The guide rail fixing portion 106b is flat, with the guide portion 106a standing in the center in the width direction. The surface of the guide rail fixing portion 106b on the side where the guide portion 106a is provided (the surface facing the car 104) will be referred to as the front surface 106c, and the surface facing the elevator shaft wall 101a will be referred to as the back surface 106d.
[0037] The fixing structure of the fixing part 2 to the car guide rail 106 will be described using Figures 7, 8 and 9. Figure 7 is a perspective view of the fixing structure of the fixing part 2 in the car fixing device 1 according to one embodiment of the present invention, as seen from the car 104 side. Figure 8 is a perspective view of the fixing structure of the fixing part 2 in the car fixing device 1 according to one embodiment of the present invention, as seen from the hoistway wall 101a side. Figure 9 is a perspective view of the fixing structure of the fixing part 2 in the car fixing device 1 according to one embodiment of the present invention, as seen from the hoistway wall 101a side, and shows the state before the car fixing device 1 is bolted.
[0038] As described above, the rotation suppression members 21A and 21B, the rail clip 23, and the fasteners 24 and 25, together with the fixing member 22, constitute the fixing portion 2. The surface 22c of the flat fixing member 22 that faces the car 104 will be referred to as the front surface, and the surface that faces the elevator shaft wall 101a (the surface opposite to the front surface 22c) will be referred to as the back surface 22d.
[0039] The shape of the fixing member 22 in Figures 7, 8, and 9 when viewed from a direction perpendicular to the front surface 22c or the back surface 22d is rectangular, unlike the shape of the fixing member 22 in Figure 3. In particular, in Figures 7, 8, and 9, the fixing member 22 is configured to form a rectangle with its longitudinal direction along the width direction of the car guide rail 106. From another perspective, the fixing member 22 in Figures 7, 8, and 9 has the same shape as the fixing member 22 in Figure 3 when it is not provided with the vertical extension portion 223 and is configured only with the horizontal extension portion 222. In this example, the stopper pin insertion hole 221 can be brought closer to the fixing support portion 22a (see Figure 8) of the fixing member 22, and the rotational moment acting on the fixing member 22 can be reduced.
[0040] The shape of the fixing member 22 is not limited to the shape shown in FIG. 3 or the shapes shown in FIGS. 7, 8 and 9, and may be other shapes.
[0041] 8 and 9, the fixing member 22 is fixed to the guide rail fixing portion 106b of the car guide rail 106 so that the surface 22c of the fixing member 22 faces the back surface 106d of the guide rail fixing portion 106b. In this embodiment, the fixing member 22 is assembled to the car guide rail 106 so that the surface 22c of the fixing member 22 and the back surface 106d of the guide rail fixing portion 106b are in direct contact with each other.
[0042] On the rear surface 22d side of the fixed member 22, rotation suppressing members 21A and 21B are disposed.
[0043] As shown in FIG. 9, the rail clip 23, the fixing member 22, and the rotation suppressing members 21A and 21B have insertion holes 234, 224, and 213 for inserting the bolt 24 therethrough.
[0044] In this embodiment, two rail clips 23 and fasteners 24, 25 are arranged on each side surface 106e of the guide rail fixing portion 106b, and two rail clips 23 and fasteners 24, 25 are arranged on each side surface 106f of the guide rail fixing portion 106b. That is, two rail clips 23 and two fasteners 24, 25 are arranged on each side of the guide rail fixing portion 106b.
[0045] The fastening structure of the fixing member 22 using the rail clip 23 and the rotation suppressing members 21A and 21B will be described with reference to Fig. 10. Fig. 10 is a cross-sectional view showing the fastening structure of the car fixing device 1 according to one embodiment of the present invention.
[0046] As shown in Fig. 10, a rail clip 23 is disposed on the surface 22c side of the fixing member 22. The rail clip 23, rotation restricting members 21A, 21B, and fixing member 22 are fastened together with a bolt 24 and a nut 25 (see Fig. 8) that constitute a fastener, so that the rail clip 23 and the rotation restricting members 21A, 21B hold the fixing member 22 and the rail clip 23 and the fixing member 22 hold the car guide rail 106. With this configuration, the fixing part 2 is fixed to the car guide rail 106.
[0047] The rail clip 23 constitutes a clamping member (first clamping member) that clamps the fixed member 22 from the front surface 22c side (the car guide rail 106 side) of the fixed member 22. The rotation suppressing members 21A and 21B constitute clamping members (second clamping members) that clamp the fixed member 22 from the back surface 22d side (the side opposite to the car guide rail 106).
[0048] That is, the elevator device 100 of this embodiment is provided with fasteners 24, 25 that penetrate the first clamping member 23, the fixed member 22, and the second clamping members 21A, 21B and fasten the first clamping member 23, the fixed member 22, and the second clamping members 21A, 21B together.
[0049] The first clamping member 23, the fixed member 22 and the second clamping members 21A, 21B are fastened together with fasteners 24, 25, so that the first clamping member 23 and the fixed member 22 clamp the car guide rail 106, and the first clamping member 23 and the second clamping members 21A, 21B clamp the fixed member 22.
[0050] The car guide rail 106 has a guide portion 106a that guides the car 104, and a guide rail fixing portion 106b that is fixed to the hoistway wall 101a side. The first clamping member 23 is configured to clamp widthwise side ends 106g and 106h (near side surfaces 106e and 106f) of the guide rail fixing portion 106b between itself and the fixing member 22. This makes it possible to use rail clips 23 that fix the car guide rail 106 to the hoistway wall 101a side, thereby enabling the use of standardized parts.
[0051] In the fastening structure of the fixing member 22 using the rail clip 23 and the rotation suppression members 21A, 21B, the fixing member 22 is clamped between the rail clip 23 and the rotation suppression members 21A, 21B, and the car guide rail 106 is fastened with the bolt 24 and nut 25 in a state where its guide rail fixing portion 106b is clamped between the rail clip 23 and the fixing member 22.
[0052] At the contact portion between the rail clip 23 and the guide rail fixing portion 106b, the contact surface 233 of the rail clip 23 comes into contact with the surface 106c of the guide rail fixing portion 106. On the other hand, at the contact portion between the rail clip 23 and the fixing member 22, the contact surface 234 of the rail clip 23 comes into contact with the surface 22c of the fixing member 22. In this case, the area of the contact surface 234 where the rail clip 23 comes into contact with the surface 22c of the fixing member 22 is small, making it difficult for the rail clip 23 to obtain a large frictional fixing force with respect to the fixing member 22.
[0053] 7, the stopper pin insertion hole 221 of the fixed member 22 through which the stopper pin 31 is inserted is supported in a cantilever manner relative to the fixed support portion 22a of the fixed member 22 (the same applies to the fixed member 22 in FIG. 3). Therefore, when the stopper pin 31 is inserted into the stopper pin insertion hole 221 of the fixed member 22 and the fixed member 22 receives the load of the car 104, a rotational moment acts on the fixed member 22.
[0054] If rotation suppressing members 21A and 21B were not used, the frictional fixing force of rail clip 23 against fixing member 22 would not be enough to resist this rotation moment, and slippage would occur between rail clip 23 and fixing member 22. If slippage occurs between rail clip 23 and fixing member 22, the rotation moment would cause one end of fixing member 22 on the side where stopper pin insertion hole 221 is provided in the horizontal direction to rotate in a direction upward relative to the other end.
[0055] Even when rotation suppression members 21A, 21B are not used, when the fixing member 22 rotates due to a rotational moment, the bolt 24 comes into contact with the side surfaces 106e, 106f of the car guide rail 106, and further rotation of the fixing member 22 is suppressed.
[0056] However, if slippage occurs between the rail clip 23 and the fixing member 22, the car fixing device 1 loses its reliability as a fixing device, and there is a problem with using it as is. Alternatively, if the stopper pin 31 comes into contact with the stopper pin insertion hole 221 in the width direction (horizontal direction) of the car guide rail 106 before rotation of the fixing member 22 is prevented by contact between the bolt 24 and the side surfaces 106e, 106f of the car guide rail 106, and if the contact pressure between the stopper pin 31 and the stopper pin insertion hole 221 becomes large, there is a risk that the stopper pin 31 cannot be removed from the stopper pin insertion hole 221. In other words, there is a risk that the fixing of the car 104 by the fixing part 2 cannot be released.
[0057] In this embodiment, rotation of the fixed member 22 due to the rotation moment is suppressed by using the rotation suppressing members 21A and 21B.
[0058] 11 and 12, along with Fig. 7, rotation suppressing members 21A and 21B and fixing member 22 will be described. Fig. 11 is a plan view of a rotation suppressing member according to one embodiment of the present invention. Fig. 12 is a plan view of fixing member 22 according to one embodiment of the present invention.
[0059] The left diagram in Fig. 11 is a front view of rotation suppressing members 21A and 21B, and the right diagram is a side view of rotation suppressing members 21A and 21B. In Fig. 11, DrA represents the up-down direction (height direction) of rotation suppressing members 21A and 21B, DrB represents the width direction of rotation suppressing members 21A and 21B, and DrC represents the thickness direction of rotation suppressing members 21A and 21B. The width direction DrB coincides with the width direction of car guide rail 106.
[0060] 11, each of the rotation suppressing members 21A and 21B has a surface 21c facing the car 104 and opposite the fixed member 22 as a front surface, and a surface 21d facing the elevator shaft wall 101a as a back surface. A convex portion 211 is provided on the surface 21c of the rotation suppressing members 21A and 21B.
[0061] The convex portions 211 are provided on the front surface 21c of the fixing member 22 so as to protrude from the back surface 22d side toward the front surface 22c side of the fixing member 22. The convex portions 211 have side surfaces 211a that rise perpendicularly to the front surface 21c. The convex portions 211 are provided on both ends of the rotation suppressing members 21A and 21B in the vertical direction.
[0062] When viewed from the convex portion 211, a groove-shaped portion is formed in the fixing member 22. This groove-shaped portion has the surface 21c of the fixing member 22 as its bottom surface and the side surface 211a of the convex portion 211 as its side surface. In this case, the side surface 211a of the convex portion 211 provided at the upper end of the fixing member 22 and the side surface 211a of the convex portion 211 provided at the lower end face each other in the up-down direction DrA.
[0063] As shown in Figures 7 and 12, when the rotation suppression members 21A, 21B and the fixing member 22 are assembled, the side surface 211a of the convex portion 211 provided at the upper end of the rotation suppression members 21A, 21B faces the upper side surface 22e of the fixing member 22, and the side surface 211a of the convex portion 211 provided at the lower end of the rotation suppression members 21A, 21B faces the lower side surface 22f of the fixing member 22.
[0064] The convex portion 211 and its side surface 211a face the upper side surface 22e or the lower side surface 22f of the fixing member 22, and therefore function as a regulating portion (rotation regulating portion) that regulates the rotation of the fixing member 22 when a rotational moment described below acts on the fixing member 22.
[0065] The convex portions 211 of the rotation suppressing members 21A, 21B form side surfaces 211b at one end in the width direction DrB that face the side surfaces 106e, 106f of the guide rail fixing portion 106b. This side surface 211b abuts against the side surfaces 106e, 106f of the guide rail fixing portion 106b of the car guide rail 106 when the fixing portion 2 is assembled to the car guide rail 106, as shown in FIG.
[0066] The convex portion 211 and its side surface 211b constitute a contact portion that comes into contact with the side surfaces 106e and 106f of the guide rail fixing portion 106b.
[0067] As described above, the elevator device 100 of this embodiment has the following features: In an elevator device 100, a car fixing device 1 that fixes a car 104 to a car guide rail 106 is provided on a car top 104a of the car 104. The car fixing device 1 is configured to include a fixing section 2 having a fixing member 22 provided with a through hole 221, a first clamping member (rail clip) 23 that clamps the fixing member 22 from the side of the car guide rail 106, and second clamping members (rotation suppressing members) 21A, 21B that clamp the fixing member 22 from the side opposite to the first clamping member 23, and a stopper pin operating mechanism section 3 having a stopper pin 31 that is inserted into the through hole 221, The second clamping members 21A and 21B have contact portions 211 that come into contact with the side surfaces 106e and 106f of the car guide rail 106.
[0068] In this case, the abutting portions 211 of the second clamping members 21A and 21B may be configured to abut against the side surfaces 106e and 106f of the guide rail fixing portion 106b of the car guide rail 106. Because the side surfaces 106e and 106f of the guide rail fixing portion 106b are located near the abutting portions 211, the abutting portions 211 can be provided without increasing the size of the rotation suppressing members 21A and 21B.
[0069] By bringing side surface 211b of convex portion 211 into contact with side surfaces 106e, 106f of guide rail fixing portion 106b, rotation suppressing members 21A, 21B bear all or part of the rotation moment acting on fixing member 22. As a result, rotation suppressing members 21A, 21B suppress the rotation of fixing member 22. By rotation suppressing members 21A, 21B suppressing the rotation of fixing member 22, slippage that occurs between rail clip 23 and fixing member 22 can be suppressed, and fixing member 22 can be firmly fixed to car guide rail 106. This improves the reliability of car fixing device 1 as a fixing device.
[0070] In order to bring the side surface 211b of the convex portion 211 into contact with the side surfaces 106e and 106f of the guide rail fixing portion 106b, it is necessary to adjust the positions of the rotation suppressing members 21A and 21B on the fixing member 22 relative to the guide rail fixing portion 106b.
[0071] 11, the rotation suppressing members 21A, 21B will be described. The rotation suppressing members 21A, 21B are provided with bolt insertion holes 213 through which the bolts 24 are inserted. The bolt insertion holes 213 are formed so that the length dimension L213b in the width direction DrB is greater than the length dimension L213a in the up-down direction DrA. This makes it possible to adjust the position of the rotation suppressing members 21A, 21B with respect to the guide rail fixing portion 106b on the fixing member 22 so that the side surface 211b of the convex portion 211 abuts against the side surfaces 106e, 106f of the guide rail fixing portion 106b.
[0072] In this embodiment, two bolt insertion holes 213 are provided along the up-down direction DrA. The number of bolt insertion holes 213 is not limited to two and may be determined according to the number of fastening bolts 24. For example, in the case of Fig. 3, the number of bolt insertion holes 213 in the rotation suppression members 21A and 21B is three.
[0073] 12, the bolt insertion holes 224 formed in the fixing member 22 are circular holes. Similar to the rotation suppressing members 21A and 21B, two bolt insertion holes 224 are formed in the up-down direction DrA. Furthermore, two bolt insertion holes 224 are formed in the fixing member 22 in the width direction DrB, for a total of four bolt insertion holes 224.
[0074] The number of bolt insertion holes 224 in the direction along the width direction DrB corresponds to the number of rotation suppressing members 21A, 21B. The number of bolt insertion holes 224 in the direction along the up-down direction DrA is not limited to two and may be determined according to the number of fastenings by the bolts 24. For example, in the case of Fig. 3, the number of bolt insertion holes 224 in the fixing member 22 is three.
[0075] The present invention is not limited to the above-described embodiments, but includes various modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and are not necessarily limited to those including all of the configurations. Furthermore, it is possible to replace part of the configuration of the embodiments with other configurations. Furthermore, it is possible to add, delete, or replace part of the configuration of the embodiments with other configurations. [Explanation of symbols]
