[0005] Patent Document 1: Japanese Patent Application Publication No. 2000-203774 Summary of the invention

[0006] Problems to be solved by the invention

[0007] The fixing mechanism is a plate-like component, one end of which is supported on the guide rail by the rail clamp in the horizontal direction, and the other end of which is protruded in a cantilever beam-like manner relative to the support portion of the guide rail, and a locking rod insertion hole is provided in the protruding portion. Therefore, the fixing mechanism is subjected to a rotational torque due to the load of the elevator car. The rail clamp withstands the rotational torque acting on the fixing mechanism by the frictional holding force acting on the contact portion with the fixing mechanism. The frictional holding force at the rail clamp has a limit, and when the magnitude of the rotational torque acting on the fixing mechanism exceeds the frictional holding force of the rail clamp, slippage occurs between the rail clamp and the fixing mechanism, and the fixing mechanism can no longer maintain its reliability as a fixing member for fixing the elevator car.

[0008] Hereinafter, the elevator car, the locking rod and the fixing mechanism are referred to as the car, the stop pin and the fixing member, respectively, and the device for fixing the car at a height position for maintenance work is referred to as the car fixing device.

[0009] An object of the present invention is to provide an elevator apparatus in which, in a car fixing device, slippage between a rail clamp and a fixing member caused by a rotational moment acting on the fixing member can be suppressed.

[0010] Technical solutions to solve problems

[0011] In order to achieve the above object, the elevator apparatus of the present invention is an elevator apparatus having a car fixing device on the car top of the car for fixing the car relative to the car guide rail, wherein:

[0012] The car fixing device is composed of a fixing part and a stop pin operating mechanism part, wherein the fixing part includes a fixing component provided with a through hole and a first clamping component clamping the fixing component from one side of the car guide rail, and a second clamping component clamping the fixing component from a side opposite to the first clamping component, and the stop pin operating mechanism part has a stop pin that can be inserted into the through hole,

[0013] The second clamping member has a contact portion that contacts a side surface of the car guide rail.

[0014] Effects of the Invention

[0015] According to the present invention, in the car fixing device of the elevator equipment, the abutment portion of the second clamping member abuts against the side surface of the car guide rail, thereby suppressing the rotation of the fixing member caused by the rotational moment and suppressing the sliding between the rail clamp and the fixing member. Therefore, the fixing member is firmly fixed to the guide rail.

[0016] In addition, problems, structures, and effects other than those described above will be explained through the following description of the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, in the following description, the up and down direction (vertical direction) is defined as being consistent with the lifting 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.

[0030] refer to Figure 1 , the structure of the elevator device 100 is described. Figure 1 This is a schematic diagram of an elevator device 100 according to an embodiment of the present invention.

[0031] The elevator equipment 100 includes a car 104 , a counterweight 105 , a hoisting machine 103 , a car guide rail 106 , a counterweight guide rail 108 , a control device (elevator control device) 102 , and a car fixing device 1 .

[0032] The car 104 and the counterweight 105 are installed in a hoistway 101 provided in a building, and are suspended in a bucket-like manner by a main rope (not shown) wound around the hoisting machine 103. The car 104 and the counterweight 105 are connected by the main rope.

[0033] A main rope (not shown) is wound around the hoisting machine 103 , and the hoisting machine 103 operates the main rope to raise and lower the car 104 and the counterweight 105 in the hoistway 101 .

[0034] The car guide rail 106 and the counterweight guide rail 108 extend in the vertical direction (vertical direction) in the hoistway 101 and are fixed to the hoistway wall 101a by a rail bracket 111. The car guide rail 106 guides the rise and fall of the car 104. The counterweight guide rail 108 guides the rise and fall of the counterweight 105.

[0035] The control device 102 controls the lifting operation of the elevator system 100. To this end, the control device 102 controls the driving of the traction machine 103.

[0036] The car fixing device 1 is a device for positioning and fixing the car top (top surface) 104a of the car 104 on a specific floor where the traction machine 103 and the control device 102 are arranged when performing operations such as inspection and repair of the traction machine 103 and the control device 102, and is installed on the car top 104a of the car 104.

[0037] use Figure 1 and Figure 2 , automatic adjustment of the car position during maintenance work of the elevator device 100 will be described. Figure 2 This is a schematic diagram showing a state in which a car 104 is positioned and stopped at a predetermined position during maintenance work by a control device 102 in an elevator apparatus 100 according to an embodiment of the present invention.

[0038] In the elevator device 100 of this embodiment, the hoisting machine 103 and the control device 102 are arranged on a specific floor above the height position obtained by adding the height He of one floor to the floor level 1FL of the lowest floor. The specific floor is a floor where the hoisting machine 103 and the control device 102 are installed. There are cases where the specific floor is referred to as the installation floor of the hoisting machine 103 and the control device 102, or simply as the installation floor. In addition, Figure 2 In FIG. 1 , an example in which the hoisting machine 103 and the control device 102 are installed on the second floor is shown, and the specific floor (installation floor) is the second floor.

[0039] When performing inspection and repair work on the hoisting machine 103 and the control device 102, the car top (top surface) 104a of the car 104 is positioned at the floor level 2FL of the second floor, which is a specific floor, and the operator performs work on the car top 104a of the car 104. That is, in this embodiment, the car top 104a of the car 104 is the foothold of the operator. Therefore, the operator rides from the elevator station floor to the car top 104a.

[0040] When the operator gets on the car top 104a from the boarding floor, the car top 104a of the car 104 is positioned so as to coincide with the floor level of the boarding floor. For example, when the boarding floor is the 1st floor, the car top 104a of the car 104 is positioned at the floor level 1FL of the 1st floor. In this case, the car top 104a does not need to coincide with the floor level 1FL of the boarding floor, and can be positioned within a range ΔH where the operator can get on.

[0041] When the car top (top surface) 104a of the car 104 is positioned at the floor level 2FL of the second floor, which is a specific floor, the car fixing device 1 (reference Figure 3 ) fix the car 104. In addition, when working on the car top 104a, a handrail 104b is provided on the car top 104a. The handrail 104b is stored in the car top 104a in a folded state and unfolded on the car top 104a during working.

[0042] use Figure 3 The car fixing device 1 will be described. Figure 3 It is a perspective view showing a schematic structure of a car fixing device 1 according to an embodiment of the present invention.

[0043] The car fixing device 1 is operated by a worker who has boarded the car top portion 104a at the car top portion 104a, thereby fixing the car 104 to the guide rail 106. Therefore, the car fixing device 1 is installed at the car top portion 104a.

[0044] The car fixing device 1 is configured to include a fixing portion 2 having a fixing member 22 provided with a through hole 221 , and a stopper pin operating mechanism portion 3 having a stopper pin 31 insertable into the through hole 221 .

[0045] The fixing portion 2 has a fixing member 22 formed of a plate-shaped member. Figure 3 The fixing member 22 is in the shape of a letter L and is composed of a horizontal extension portion 222 extending in the horizontal direction and a vertical extension portion 223 extending in the vertical direction. Due to the shape of the fixing member 22, the freedom of configuration of the stopper pin operating mechanism portion 3 having the stopper pin 31 is improved, and the freedom of design of the car 104 and the car fixing device 1 is improved.

[0046] One end portion of the horizontal direction extending portion 222 in the horizontal direction constitutes a fixed support portion 22a fixedly supported on the car guide rail 106. The fixed support portion 22a is as shown in FIG. Figure 7 and Figure 8 As described in , the rotation restraining members 21A, 21B, the rail clamp 23, and the fasteners 24, 25 are used to fix to the car guide rail 106. Therefore, the rotation restraining members 21A, 21B, the rail clamp 23, and the fasteners 24, 25 can be regarded as constituting the components of the fixing part 2 together with the fixing member 22.

[0047] The vertical extension portion 223 is provided to extend downward from the other horizontal end portion of the horizontal extension portion 222. A through hole 221 is provided in the vertical extension portion 223. The through hole 221 is located below the fixed support portion 22a.

[0048] 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 locked by the fixing member 22 of the fixing portion 2, and the stopper pin insertion hole 221 is a locking portion where the stopper pin 31 is locked.

[0049] use Figure 4 , Figure 5 and Figure 6 , the stop pin operating mechanism portion 3 will be described. Figure 4 1 is a plan view of a car fixing device 1 according to an embodiment of the present invention as viewed from above. Figure 5 1 is a plan view of a car fixing device 1 according to an embodiment of the present invention, viewed from the side. Figure 6 Yes Figure 4 This is an enlarged view of the VI part. Figure 5 In the figure, the car guide rail 106 and the fixing portion 2 are omitted.

[0050] like Figure 4 As shown, one set of the car fixing devices 1 is provided on each of the two side portions of the car 104 in the width direction W104 of the car 104 .

[0051] like Figure 5 As shown, the stopper pin operating mechanism 3 includes a stopper pin 31 and a stopper pin operating mechanism 32 for operating the stopper pin 31. The stopper pin 31 is mounted on the stopper pin operating mechanism 3 so as to be movable forward and backward in the longitudinal direction thereof, and the stopper pin operating mechanism 32 operates the stopper pin 31 to be movable forward and backward in the longitudinal direction.

[0052] like Figure 6 As shown, the stopper pin 31 is located at the retreat position during normal operation of the elevator device 100, and is pushed out from the retreat position during inspection and repair of the traction machine 103 and the control device 102, and is inserted into the stopper pin insertion hole 221 (see Figure 3 ) in FIG. 31A indicates the stop pin 31 when it is in the retracted position, and 31B indicates the stop pin 31 when it advances from the retracted position.

[0053] The stopper pin 31 is inserted into the stopper pin insertion hole 221 and is locked by the fixing member 22 of the fixing portion 2, whereby the load of the car 104 is supported by 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.

[0054] In addition, the car guide rail 106 is as follows Figure 6 As shown, the elevator car 104 has a guide portion 106a for guiding the elevator car 104 and a guide portion 106a fixed to the hoistway wall 101a (reference Figure 1) side. The guide rail fixing portion 106b is formed in a flat plate shape, and the guide portion 106a is uprightly provided in the center portion 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 on the side opposite to the car 104) is called the front surface 106c, and the surface on the side opposite to the hoistway wall 101a is called the back surface 106d.

[0055] use Figure 7 , Figure 8 and Fig. 9 , the fixing structure of the fixing portion 2 with respect to the car guide rail 106 will be described. Figure 7 This is a perspective view of the fixing structure of the fixing portion 2 in the car fixing device 1 as viewed from the car 104 side according to one embodiment of the present invention. Figure 8 This is a perspective view of the fixing structure of the fixing portion 2 in the car fixing device 1 as viewed from the hoistway wall 101a side according to one embodiment of the present invention. Fig. 9 This is a perspective view of the fixing structure of the fixing portion 2 in the car fixing device 1 according to one embodiment of the present invention as viewed from the hoistway wall 101a side, and is a view showing a state before the car fixing device 1 is fastened with bolts.

[0056] As described above, the rotation inhibiting members 21A, 21B, the rail clamp 23, and the fasteners 24, 25 together with the fixing member 22 constitute the fixing portion 2. In the flat fixing member 22, the surface 22c on the side opposite to the car 104 is called the front surface, and the surface on the side opposite to the hoistway wall 101a (the surface on the opposite side to the front surface 22c) is called the back surface 22d.

[0057] Figure 7 , Figure 8 and Fig. 9 The shape of the fixing member 22 when viewed from a direction perpendicular to the front face 22c or the back face 22d is similar to Figure 3 The shape of the fixing member 22 is different, and it is rectangular. Figure 7 , Figure 8 and Fig. 9 In the embodiment, the fixing member 22 is configured to form a rectangle having a long side along the width direction of the car guide rail 106. From another perspective, Figure 7 , Figure 8 and Fig. 9 The fixing member 22 is not provided with Figure 3 The same shape as in the case where the vertical extension part 223 is formed only by the horizontal extension part 222. In this example, the stopper pin insertion hole 221 can be close to the fixed support part 22a of the fixing member 22 (refer to Figure 8 ), which can reduce the rotational torque acting on the fixing component 22.

[0058] The shape of the fixing member 22 is not limited to Figure 3 shape, or Figure 7 , Figure 8 and Fig. 9 The shape may also be other shapes.

[0059] like Figure 8 and Fig. 9 As shown, the fixing member 22 is fixed to the guide rail fixing portion 106b of the car guide rail 106 in such a manner that its front face 22c faces the back face 106d of the guide rail fixing portion 106b. In the present embodiment, the fixing member 22 is mounted on the car guide rail 106 so that the front face 22c of the fixing member 22 is in direct contact with the back face 106d of the guide rail fixing portion 106b.

[0060] The rotation suppressing members 21A and 21B are disposed on the back surface 22 d side of the fixing member 22 .

[0061] like Fig. 9 As shown, insertion holes 234 , 224 , and 213 for inserting the bolts 24 are formed in the rail clip 23 , the fixing member 22 , and the rotation restraining members 21A and 21B.

[0062] In this embodiment, two rail clips 23 and fasteners 24, 25 are arranged on the side 106e of the guide rail fixing portion 106b, and two are arranged on the side 106f. That is, two rail clips 23 and fasteners 24, 25 are arranged on both sides of the guide rail fixing portion 106b.

[0063] use Fig.10 , a fastening structure of the fixing member 22 using the rail clamp 23 and the rotation restraining members 21A, 21B will be described. Fig.10 It is a cross-sectional view showing the fastening structure of the car fixing device 1 according to one embodiment of the present invention.

[0064] like Fig.10 As shown in FIG. 1 , a rail clamp 23 is provided on the front side 22c of the fixing member 22. The rail clamp 23, the rotation inhibiting members 21A, 21B and the fixing member 22 are fastened by bolts 24 and nuts 25 (see FIG. 1 ) constituting fasteners in such a manner that the rail clamp 23 and the rotation inhibiting members 21A, 21B hold the fixing member 22, and the rail clamp 23 and the fixing member 22 hold the car guide rail 106. Figure 8 ) is fastened. With such a structure, the fixing portion 2 is fixed to the guide rail 106 for the car.

[0065] The rail clamp 23 constitutes a clamping member (first clamping member) that clamps the fixing member 22 from the front 22c side (the car guide rail 106 side) of the fixing member 22. The rotation inhibiting members 21A and 21B constitute a clamping member (second clamping member) that clamps the fixing member 22 from the back 22d side (the side opposite to the car guide rail 106).

[0066] That is, the elevator apparatus 100 of the present embodiment includes the fasteners 24 and 25 that penetrate through the first clamping member 23, the fixing member 22, and the second clamping members 21A and 21B and fasten the first clamping member 23, the fixing member 22, and the second clamping members 21A and 21B.

[0067] The first clamping member 23, the fixing member 22, and the second clamping members 21A, 21B are fastened by the fasteners 24, 25, so that the car guide rail 106 is clamped by the first clamping member 23 and the fixing member 22, and the fixing member 22 is clamped by the first clamping member 23 and the second clamping members 21A, 21B.

[0068] The car guide rail 106 has a guide portion 106a for guiding the car 104 and a guide rail fixing portion 106b fixed to one side of the hoistway wall 101a. The first clamping member 23 is configured to clamp the width direction side ends 106g and 106h (near the side surfaces 106e and 106f) of the guide rail fixing portion 106b between the first clamping member 23 and the fixing member 22. Thus, the rail clamp 23 that fixes the car guide rail 106 to one side of the hoistway wall 101a can be used to achieve the sharing of components.

[0069] In the fastening structure of the fixing component 22 using the rail clamp 23 and the rotation inhibiting components 21A, 21B, the fixing component 22 is clamped by the rail clamp 23 and the rotation inhibiting components 21A, 21B, and the bolt 24 and the nut 25 are tightened with the car guide rail 106 having its guide rail fixing component 106b clamped by the rail clamp 23 and the fixing component 22.

[0070] 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 contacts the front 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 contacts the front surface 22c of the fixing member 22. In this case, the area of ​​the contact surface 234 where the rail clip 23 contacts the front surface 22c of the fixing member 22 is small, and it is difficult to obtain a large friction fixing force with the rail clip 23 relative to the fixing member 22.

[0071] In addition, according to Figure 7 It can be seen that the stopper pin insertion hole 221 of the fixing member 22 through which the stopper pin 31 is inserted is supported in a cantilever beam-like state with respect to the fixing support portion 22a of the fixing member 22 ( Figure 3 The same is true for the fixing member 22 of the car 104. Therefore, the stopper pin 31 is inserted into the stopper pin insertion hole 221 of the fixing member 22. When the fixing member 22 receives the load of the car 104, a rotational moment acts on the fixing member 22.

[0072] If the rotation inhibiting members 21A and 21B are not used, the friction fixing force on the fixing member 22 generated by the rail clamp 23 is insufficient to resist the rotation torque, and sliding occurs between the rail clamp 23 and the fixing member 22. When sliding occurs between the rail clamp 23 and the fixing member 22, the fixing member 22 rotates in a direction in which one end portion of the side where the stopper pin insertion hole 221 is provided in the horizontal direction rises relative to the other end portion due to the rotation torque.

[0073] Even when the rotation restraining members 21A and 21B are not used, when the fixing member 22 receives the rotational torque and rotates, and the bolts 24 thereby come into contact with the side surfaces 106e and 106f of the car guide rail 106, further rotation of the fixing member 22 is prevented.

[0074] However, the car fixing device 1 that has slid between the rail clamp 23 and the fixing member 22 has lost its reliability as a fixing device, and there is a problem when it is used in this state. Alternatively, before the rotation of the fixing member 22 is suppressed due to the contact between the bolt 24 and the side surfaces 106e and 106f of the car guide rail 106, the stop pin 31 and the stop pin insertion hole 221 in the width direction (horizontal direction) of the car guide rail 106 come into contact, and the contact pressure between the stop pin 31 and the stop pin insertion hole 221 is large, there is also a risk that the stop pin 31 cannot be pulled out of the stop pin insertion hole 221. In other words, there is a risk that the fixing of the car 104 by the fixing portion 2 cannot be released.

[0075] In the present embodiment, the rotation of the fixing member 2 due to the rotational moment is suppressed by using the rotation suppressing members 21A and 21B.

[0076] and Figure 7 Use together Fig.11 and Fig.12 , the rotation suppressing members 21A, 21B and the fixing member 22 will be described. Fig.11 It is a plan view of a rotation restraining member according to an embodiment of the present invention. Fig.12 FIG. 2 is a plan view of a fixing member 22 according to an embodiment of the present invention.

[0077] Fig.11 The left figure is a front view of the rotation suppression components 21A and 21B, and the right figure is a side view of the rotation suppression components 21A and 21B. Fig.11, DrA indicates the vertical direction (height direction) of the rotation restraining members 21A and 21B, DrB indicates the width direction of the rotation restraining members 21A and 21B, and DrC indicates the thickness direction of the rotation restraining members 21A and 21B. The width direction DrB coincides with the width direction of the car guide rail 106.

[0078] like Fig.11 As shown, the rotation restraining members 21A and 21B have a front surface 21c facing the fixing member 22 toward the car 104 and a rear surface 21d facing the hoistway wall 101a. A convex portion 211 is provided on the front surface 21c of the rotation restraining members 21A and 21B.

[0079] The convex portion 211 is provided upright on the front surface 21c of the fixing member 22 so as to protrude from the back surface 22d side to the front surface 22c side of the fixing member 22. The convex portion 211 has a side surface 211a that stands vertically relative to the front surface 21c. The convex portion 211 is provided at both ends of the rotation restraining members 21A and 21B in the vertical direction.

[0080] When viewed from the convex portion 211, a groove-shaped portion is formed in the fixing member 22. The groove-shaped portion has the front surface 21c of the fixing member 22 as the bottom surface and the side surface 211a of the convex portion 211 as the 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.

[0081] like Figure 7 and Fig.12 As shown, when the rotation suppression components 21A, 21B are assembled with the fixing component 22, the side 211a of the convex portion 211 arranged at the upper end of the rotation suppression components 21A, 21B is opposite to the upper side 22e of the fixing component 22, and the side 211a of the convex portion 211 arranged at the lower end of the rotation suppression components 21A, 21B is opposite to the lower side 22f of the fixing component 22.

[0082] The convex portion 211 and its side surface 211 a face the upper side surface 22 e or the lower side surface 22 f of the fixing member 22 , and thus function as a restriction portion (rotation restriction portion) that restricts the rotation of the fixing member 22 when a rotational moment described later acts on the fixing member 22 .

[0083] The convex portion 211 of the rotation restraining member 21A, 21B forms a side surface 211b at one end in the width direction DrB that is opposite to the side surfaces 106e, 106f of the guide rail fixing portion 106b. Figure 7As shown, in a state where the fixing portion 2 is attached to the car guide rail 106 , it abuts against the side surfaces 106 e and 106 f of the guide rail fixing portion 106 b of the car guide rail 106 .

[0084] The convex portion 211 and its side surface 211 b constitute a contact portion that contacts the side surfaces 106 e and 106 f of the guide rail fixing portion 106 b .

[0085] As described above, the elevator apparatus 100 of the present embodiment is an elevator apparatus 100 having a car fixing device 1 for fixing the car 104 to the car guide rail 106 at the car top 104a of the car 104.

[0086] The car fixing device 1 is configured to include a fixing portion 2 and a stop pin operating mechanism portion 3, wherein the fixing portion 2 has a fixing member 22 having a through hole 221, a first clamping member (rail clamp) 23 clamping the fixing member 22 from one side of the car guide rail 106, and second clamping members (rotation inhibiting members) 21A, 21B clamping the fixing member 22 from the side opposite to the first clamping member 23, and the stop pin operating mechanism portion 3 has a stop pin 31 that can be inserted into the through hole 221.

[0087] The second holding members 21A and 21B have abutting portions 211 that abut against the side surfaces 106e and 106f of the car guide rail 106.

[0088] In this case, the contact portion 211 of the second clamping members 21A and 21B may be configured to contact the side surfaces 106e and 106f of the guide rail fixing portion 106b of the car guide rail 106. Since the side surfaces 106e and 106f of the guide rail fixing portion 106b are located near the contact portion 211, the contact portion 211 can be provided without enlarging the rotation suppressing members 21A and 21B.

[0089] The side surface 211b of the convex portion 211 is brought into contact with the side surfaces 106e and 106f of the guide rail fixing portion 106b, and the rotation suppressing members 21A and 21B receive all or part of the rotation torque acting on the fixing member 22. As a result, the rotation suppressing members 21A and 21B suppress the rotation of the fixing member 22. Since the rotation suppressing members 21A and 21B suppress the rotation of the fixing member 22, it is possible to suppress the slippage between the rail clamp 23 and the fixing member 22, and the fixing member 22 can be firmly fixed to the car guide rail 106. In addition, the reliability of the car fixing device 1 as a fixing device is improved.

[0090] In order to make side surface 211 b of convex portion 211 abut against side surfaces 106 e and 106 f of rail fixing portion 106 b , it is necessary to adjust the positions of rotation restraining members 21A and 21B relative to rail fixing portion 106 b on fixing member 22 .

[0091] return Fig.11 , the rotation inhibiting components 21A and 21B are described. The rotation inhibiting components 21A and 21B are provided with bolt insertion holes 213 for inserting the bolts 24. The bolt insertion holes 213 are formed so that the length dimension L213b in the width direction DrB is larger than the length dimension L213a in the up-down direction DrA. Thus, the positions of the rotation inhibiting components 21A and 21B relative to the guide rail fixing portion 106b can be adjusted on the fixing component 22 so that the side surface 211b of the convex portion 211 abuts against the side surfaces 106e and 106f of the guide rail fixing portion 106b.

[0092] In addition, in this embodiment, two bolt insertion holes 213 are provided along the vertical direction DrA. The number of bolt insertion holes 213 is not limited to two, and can be provided in accordance with the number of bolts 24 to be fastened. For example, Figure 3 In this case, the number of the bolt insertion holes 213 of the rotation restraining members 21A and 21B is three.

[0093] On the other hand, Fig.12 As shown, the bolt insertion hole 224 provided in the fixing member 22 is a round hole. In addition, similarly to the rotation suppression members 21A and 21B, two bolt insertion holes 224 are provided along the vertical direction DrA. Furthermore, two bolt insertion holes 224 are provided along the width direction DrB in the fixing member 22, and a total of four bolt insertion holes 224 are provided.

[0094] The number of bolt insertion holes 224 along the width direction DrB corresponds to the number of rotation restraining members 21A and 21B. The number of bolt insertion holes 224 along the up-down direction DrA is not limited to two, and may be provided in accordance with the number of bolts 24 to be tightened. For example, Figure 3 In this case, the number of the bolt insertion holes 224 of the fixing member 22 is three.

[0095] In addition, the present invention is not limited to the above-mentioned embodiments, and includes various modified examples. For example, the above-mentioned embodiments are described in detail to explain the present invention in an easy-to-understand manner, and are not limited to having all structures. In addition, a part of the structure of the embodiment can be replaced with other structures. In addition, for a part of the structure of the embodiment, other structures can be added, deleted, or replaced.
