[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2002-274769 Summary of the Invention

[0006] Problems to be solved by the invention

[0007] The vibration isolator described in Patent Document 1 includes three rubber components facing the column. These three rubber components are fixed to a single plate component. Therefore, the plate component cannot be used to independently move the three rubber components. For example, when the plate component is moved to confirm the contact of rubber component 19 with the column while rubber component 21 is in contact with the column, rubber component 21 will move while still in contact with the column. Due to the frictional resistance of rubber component 21, it may be determined that rubber component 19 is in contact with the column even though it is not.

[0008] The present invention has been made to solve the above-mentioned problems. An object of the present invention is to provide an elevator car including a vibration isolator capable of independently moving a plurality of members facing a column.

[0009] Means for solving problems

[0010] The elevator car of the present invention comprises: a car chamber; a support device that supports the car chamber; and a vibration isolator that is provided in the car chamber. The support device comprises: a lower member that supports the car chamber from below; and a column that extends upward from the lower member. A first surface, a second surface, and a third surface are formed on the column. When viewed from above, the first surface faces the car chamber side. The second surface and the third surface face opposite directions to each other. The vibration isolator comprises: a first buffer member that is opposite to the first surface; a first arm that is provided with the first buffer member; a second buffer member that is opposite to the second surface; a second arm that is provided with the second buffer member; a third buffer member that is opposite to the third surface; a third arm that is provided with the third buffer member; a first fixing unit that fixes the first arm and the second arm to the upper surface of the car chamber in a state in which the first arm and the second arm are overlapped; and a second fixing unit that fixes the first arm and the third arm to the upper surface in a state in which the first arm and the third arm are overlapped.

[0011] Effects of the Invention

[0012] The elevator car of the present invention is equipped with a vibration isolator. The vibration isolator includes: a first buffer member, which faces a first surface; a first arm, which is provided with the first buffer member; a second buffer member, which faces the second surface; a second arm, which is provided with the second buffer member; a third buffer member, which faces the third surface; a third arm, which is provided with the third buffer member; a first fixing unit; and a second fixing unit. The first fixing unit fixes the first and second arms to the upper surface of the car chamber in a state in which the first and second arms overlap. The second fixing unit fixes the first and third arms to the upper surface in a state in which the first and third arms overlap. Therefore, in the elevator car of the present invention, the first, second, and third buffer members can be moved independently. That is, the position of the first buffer member can be adjusted using the first arm. The position of the second buffer member can be adjusted using the second arm. The position of the third buffer member can be adjusted using the third arm. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is a detailed description with reference to the accompanying drawings. Repetitive descriptions are appropriately simplified or omitted. In each figure, the same reference numerals indicate the same or corresponding parts.

[0040] Implementation Method 1

[0041] Figure 1This figure shows an example of an elevator device including a car 1 according to Embodiment 1. The elevator device includes a car 1 and a counterweight 2. The car 1 moves up and down in a shaft 3. The counterweight 2 moves up and down in the shaft 3. The car 1 and the counterweight 2 are suspended in the shaft 3 by means of main ropes 4. The main ropes 4 are an example of a means for suspending the car 1 and the counterweight 2 in the shaft 3. The rope winding method for suspending the car 1 and the counterweight 2 is not limited to Figure 1 Example shown.

[0042] The main rope 4 is wound around the drive sheave of the hoisting machine 5. The car 1 is driven by the hoisting machine 5. The control device 6 controls the hoisting machine 5. In other words, the control device 6 controls the movement of the car 1. The car 1 and the control device 6 are connected by a control cable 7. The control device 6 controls the equipment equipped in the car 1 via the control cable 7.

[0043] Figure 1 The example in which the hoisting machine 5 and the control device 6 are installed in the machine room 8 above the hoistway 3 is shown. The hoisting machine 5 and the control device 6 may also be installed in the hoistway 3. When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be installed at the top of the hoistway 3 or in the pit.

[0044] Figure 2 It is schematically shown from Figure 1 The car 1 is viewed from the direction A. The car 1 includes a car chamber 11, a frame 12, a vibration-isolating member 13, a guide 14, and vibration-isolating members 15 and 16. The car chamber 11 forms a space for passengers to sit in. The frame 12 supports the car chamber 11. Figure 2 In the example shown, the frame 12 supports the car chamber 11 via the vibration-isolating member 13. If the car 1 does not have the vibration-isolating member 13, the frame 12 directly supports the car chamber 11. The frame 12 is an example of a device that supports the car chamber 11. The device that supports the car chamber 11 may not be in the form of a frame. Figure 2 As shown, in an elevator apparatus using a 1:1 roping method, the main rope 4 is connected to the frame 12 .

[0045] Figure 2 The frame 12 shown surrounds the car chamber 11 from top to bottom and left to right. The frame 12 includes a lower member 21, a column 22, a column 23, and an upper member 24. The lower member 21 is arranged below the car chamber 11. The lower member 21 supports the car chamber 11 from below. The column 22 extends upward from one end of the lower member 21. The column 23 extends upward from the other end of the lower member 21. The car chamber 11 is arranged between the column 22 and the column 23. The upper end of the column 22 protrudes upward from the upper surface 11a of the car chamber 11. The upper end of the column 23 protrudes upward from the upper surface 11a of the car chamber 11. The upper member 24 is connected to the upper end of the column 22 and the upper end of the column 23.

[0046] The guide members 14 are provided on the frame 12. A pair of guide rails 9 are provided in the hoistway 3. The guide rails 9 extend vertically within the hoistway 3. The car 1 is arranged between the guide rails 9. The guide members 14 arranged above and below the column 22 face the guide rail 9 on one side. The guide members 14 arranged above and below the column 23 face the guide rail 9 on the other side. The movement of the car 1 is guided by the guide rails 9.

[0047] The vibration isolator 15 is provided in the car chamber 11. The vibration isolator 15 protrudes from the car chamber 11 toward the column 22 side. The vibration isolator 16 is provided in the car chamber 11. The vibration isolator 16 protrudes from the car chamber 11 toward the column 23 side. The vibration isolators 15 and 16 limit the horizontal displacement of the car chamber 11 relative to the frame 12. As a result, the tilting of the car chamber 11 relative to the frame 12 is suppressed. Since the car 1 is equipped with the vibration isolators 15 and 16, it is possible to prevent the car chamber 11 from contacting the surrounding equipment and generating noise, or damage to the car chamber 11 and the equipment. The mechanism of the vibration isolator 16 is the same as that of the vibration isolator 15. Therefore, in the following content, the vibration isolator 15 is described in detail. Detailed description of the vibration isolator 16 is omitted.

[0048] Figure 3 It shows Figure 2 Figure 1 shows a cross section of the BB. Figure 4 It shows Figure 3 Figure 1. CC cross section of the Figure 4 In the following, the guide rail 9 is omitted. Figure 3 The X-axis and the Y-axis are set as shown. The X-axis extends horizontally in the width direction of the car 1. The Y-axis extends horizontally in the depth direction of the car 1. The X-axis and the Y-axis are perpendicular to each other.

[0049] like Figure 3 As shown, vertical surfaces 22a, 22b, and 22c are formed on the column 22 of the frame 12. Surface 22a faces the X direction. That is, when viewed from above, surface 22a faces the car chamber 11 side. Surface 22b faces the Y direction. Surface 22c faces the -Y direction. That is, surface 22b and surface 22c face opposite directions to each other. Figure 3 In the example shown, surface 22a is perpendicular to surface 22b. Surface 22a is perpendicular to surface 22c. Surface 22a is formed so as to connect surface 22b and surface 22c.

[0050] Figure 5 1 is a plan view showing the vibration isolating member 15 . Figure 6 yes Figure 5 A front view of the vibration isolation member 15 is shown. Figure 7 It shows Figure 5The vibration isolator 15 includes cushioning members 31 to 33 , arms 34 to 36 , a lower pad 37 , nuts 38 to 39 , an upper pad 40 , and bolts 41 to 42 .

[0051] The cushioning member 31 is a cylindrical member made of, for example, rubber. The cushioning member 31 faces the surface 22 a of the column 22 . The cushioning member 31 may also be in contact with the surface 22 a . The cushioning member 31 is provided on the arm 34 . Figure 8 3 is a top view showing the arm 34 . Figure 9 It is a front view showing the arm 34 . Figure 10 3 is a side view showing the arm 34. The arm 34 includes a plate member 45, a plate member 46, and a reinforcement 47, for example.

[0052] The plate member 45 and the plate member 46 are formed by bending a flat plate at a right angle. The plate member 45 is perpendicular to the X-axis. The plate member 45 is arranged opposite to the surface 22a of the column 22. A threaded hole 45a is formed in the plate member 45. The plate member 46 extends from the lower end of the plate member 45 toward the car chamber 11 side, that is, in the X direction. The width of the plate member 46 in the Y direction increases as it moves away from the plate member 45. The plate member 46 is placed on the member forming the upper surface 11a of the car chamber 11. In the following content, the member forming the upper surface 11a of the car chamber 11 is also referred to as the ceiling member 25. The reinforcement 47 is perpendicular to both the plate member 45 and the plate member 46. The reinforcement 47 is fixed to the plate member 45 and the plate member 46. In addition, the arm 34 may not have the reinforcement 47.

[0053] Figure 11 3 is a diagram showing an example of fixing the buffer member 31. The buffer member 31 is provided on the plate member 45. Figure 11 The example in which the spacer 52 is arranged between the buffer member 31 and the plate member 45 is shown. The buffer member 31 may be directly provided on the plate member 45. Figure 11 In the example shown, the bolt 53 passes through the buffer member 31 and the spacer 52. The bolt 53 passing through the buffer member 31 and the spacer 52 is screwed into the threaded hole 45a to fix the buffer member 31 to the surface 45b of the plate member 45. The surface 45b faces the -X direction.

[0054] Plate member 46 includes a pair of through-holes 46a and a pair of through-holes 46b. Through-hole 46a has a width in the X direction that is greater than its width in the Y direction. Similarly, through-hole 46b has a width in the X direction that is greater than its width in the Y direction. Through-holes 46a and 46b are aligned in the Y direction.

[0055] The cushioning member 32 is a cylindrical member made of rubber, for example. The cushioning member 32 faces the surface 22 b of the column 22 . The cushioning member 32 may also be in contact with the surface 22 b . The cushioning member 32 is provided on the arm 35 . Figure 12 3 is a plan view showing the arm 35 . Figure 13 It is a front view showing the arm 35 . Figure 14 3 is a side view showing the arm 35. The arm 35 includes a plate member 48 and a plate member 49, for example.

[0056] The plate member 48 and the plate member 49 are formed by bending a flat plate at a right angle. The plate member 48 is perpendicular to the Y-axis. The plate member 48 is arranged so that at least a portion is opposite to the surface 22b of the column 22. A threaded hole 48a is formed in the plate member 48. The plate member 49 extends from the lower end of the plate member 48 toward the arm 36 side and the car chamber 11 side, that is, in the -Y direction and the X direction. In this way, the strength required for the arm 35 can be effectively ensured for the load borne by the buffer member 32. The plate member 49 is placed on the plate member 46 of the arm 34. The arm 35 may also have a reinforcement member perpendicular to the plate member 48 and the plate member 49.

[0057] Figure 15 3 is a diagram showing an example of fixing the buffer member 32. The buffer member 32 is provided on the plate member 48. Figure 15 Shown with Figure 11 In the example shown, a spacer 54 is arranged between the buffer member 32 and the plate member 48. The buffer member 32 may be directly provided on the plate member 48. Figure 15 In the example shown, bolts 55 pass through the buffer member 32 and the spacer 54. By screwing the bolts 55 that have passed through the buffer member 32 and the spacer 54 into the threaded holes 48a, the buffer member 32 is fixed to the surface 48b of the plate member 48. The surface 48b faces the -Y direction.

[0058] A pair of through holes 49a are formed in the plate member 49. The width of the through holes 49a in the Y direction is larger than the width in the X direction. The through holes 49a are aligned in the Y direction.

[0059] The cushioning member 33 is a cylindrical member made of, for example, rubber. The cushioning member 33 faces the surface 22 c of the column 22 . The cushioning member 33 may also be in contact with the surface 22 c . The cushioning member 33 is provided on the arm 36 . Figure 16 35 is a plan view showing the arm 36. The arm 35 and the arm 36 are symmetrical with respect to the X axis. The arm 36 includes, for example, a plate member 50 and a plate member 51.

[0060] The plate member 50 and the plate member 51 are formed by bending a flat plate at a right angle. The plate member 50 is perpendicular to the Y-axis. The plate member 50 is arranged so that at least a portion is opposite to the surface 22c of the column 22. A threaded hole 50a is formed in the plate member 50. The plate member 51 extends from the lower end of the plate member 50 toward the arm 35 side and the car chamber 11 side, that is, in the Y direction and the X direction. In this way, the strength required for the arm 36 can be efficiently ensured for the load borne by the buffer member 33. The plate member 51 is placed on the plate member 46 of the arm 34. In addition, the plate member 49 does not overlap with the plate member 51. The arm 36 may also have a reinforcement member perpendicular to both the plate member 50 and the plate member 51.

[0061] The buffer component 33 and Figure 15 In the example shown, the cushioning member 33 is similarly provided on the plate member 50. For example, a spacer 56 is disposed between the cushioning member 33 and the plate member 50. The cushioning member 33 may also be provided directly on the plate member 50. When the spacer 56 is provided, a bolt 57 passes through the cushioning member 33 and the spacer 56. The cushioning member 33 is secured to the surface 50b of the plate member 50 by screwing the bolt 57, which has passed through the cushioning member 33 and the spacer 56, into the threaded hole 50a. The surface 50b faces the Y direction. The surface 48b and the surface 50b face each other.

[0062] A pair of through holes 51a are formed in the plate member 51. The width of the through holes 51a in the Y direction is larger than the width in the X direction. The through holes 51a are aligned in the Y direction.

[0063] Figure 17 It is a top view showing the fixing assembly. Figure 18 3 is a front view showing a fixing assembly. The fixing assembly is a component in which a bottom plate 37, a pair of nuts 38, and a pair of nuts 39 are integrated.

[0064] The lower plate 37 is a flat plate having a certain width. A surface 37a and a surface 37b facing opposite directions are formed on the lower plate 37. Furthermore, a pair of through-holes 37c and a pair of through-holes 37d are formed on the lower plate 37. Through-holes 37c and 37d are arranged in a row in the Y direction. Nut 38 is fixed to surface 37b, for example, by welding, corresponding to the position of through-hole 37c. The center of nut 38 coincides with the center of through-hole 37c. Nut 39 is fixed to surface 37b, for example, by welding, corresponding to the position of through-hole 37d. The center of nut 39 coincides with the center of through-hole 37d. Nuts 38 and 39 are arranged in a row in the Y direction. The lower plate 37 abuts against the ceiling member 25 from below, with surface 37a of the lower plate 37 facing the lower surface of the ceiling member 25. Alternatively, the functions of nuts 38 and 39 can be achieved by forming threaded holes in the lower plate 37.

[0065] In the example shown in this embodiment, the upper pad 40 is a flat plate having the same shape as the lower pad 37. In addition, the shape of the upper pad 40 is not limited to the same shape as the lower pad 37. Figure 19 2 is a top view of the upper pad 40. A pair of through-holes 40a and a pair of through-holes 40b are formed in the upper pad 40. The through-holes 40a and 40b are aligned in the Y direction. The upper pad 40 is placed on the plate member 49 of the arm 35 and the plate member 51 of the arm 36.

[0066] The bolt 41 and nut 38 are an example of a means for securing the arms 34 and 35 to the upper surface 11a of the car chamber 11 while the plate member 46 of the arm 34 and the plate member 49 of the arm 35 overlap. The through-hole 40a, through-hole 49a, through-hole 46a, and through-hole 37c are arranged vertically. The bolt 41 penetrates the upper pad 40, the arm 35, the arm 34, the ceiling member 25, and the lower pad 37 from above. The bolt 41 is screwed into the nut 38 below the lower pad 37. Thus, the plate member 49 of the arm 35 and the plate member 46 of the arm 34 are secured to the upper surface 11a of the car chamber 11 together with the bolt 41.

[0067] The bolt 42 and nut 39 are an example of a means for fixing the arm 34 and the arm 36 to the upper surface 11a of the car chamber 11 while the plate member 46 of the arm 34 and the plate member 51 of the arm 36 overlap. The through-hole 40b, the through-hole 51a, the through-hole 46b, and the through-hole 37d are arranged vertically. The bolt 42 penetrates the upper pad 40, the arm 36, the arm 34, the ceiling member 25, and the lower pad 37 from above. The bolt 42 is screwed into the nut 39 below the lower pad 37. Thus, the plate member 51 of the arm 36 and the plate member 46 of the arm 34 are fixed to the upper surface 11a of the car chamber 11 by the bolt 42.

[0068] In the example shown in this embodiment, buffer member 31, buffer member 32, and buffer member 33 can be independently moved. Specifically, the position of buffer member 31 can be adjusted using arm 34. The position of buffer member 32 can be adjusted using arm 35. The position of buffer member 33 can be adjusted using arm 36. Therefore, even when buffer members 32 and 33 are in contact with column 22, the contact between buffer member 31 and column 22 can be easily confirmed by moving arm 34, that is, by pressing arm 34 in the X direction.

[0069] Furthermore, depending on the thickness of the walls of the car chamber 11, it may be necessary to adjust the position of the buffer member 31 in the X direction. Since a certain gap is required between the car chamber 11 and the column 22, as the thickness of the car chamber 11 wall increases, the distance from the mounting position of the bolts 41 and 42 to the surface 22a of the column 22 increases. In the example shown in this embodiment, by finely adjusting the position of the arm 34 along the X axis, the buffer member 31 can be positioned in the desired position corresponding to the aforementioned distance. Furthermore, multiple spacers 52 may be used to adjust the position of the buffer member 31 in the X direction.

[0070] In the example shown in this embodiment, Figure 5 As shown, the plate member 46 of the arm 34 is arranged between the plane P1 and the plane P2. That is, the plate member 46 does not protrude from the plane P1 in the Y direction. The plate member 46 does not protrude from the plane P2 in the -Y direction. Plane P1 is a plane including the surface 48b of the plate member 48. Plane P2 is a plane including the surface 50b of the plate member 50. More preferably, the entire arm 34 and the buffer member 31 are arranged between the plane P1 and the plane P2. Therefore, the vibration isolation member 15 can be miniaturized. In the example shown in this embodiment, the buffer member 31, the buffer member 32 and the buffer member 33 can be independently adjusted on the basis of suppressing the height of the vibration isolation member 15 and the area occupied when viewed from above.

[0071] In the example shown in this embodiment, a gap is formed between the plate member 45 provided with the buffer member 31 and the plate member 48 provided with the buffer member 32. Therefore, when the maintenance personnel install the vibration isolating member 15 on the ceiling member 25, the maintenance personnel can confirm the status of the buffer member 31 and the status of the buffer member 32 through the gap by visual inspection or touch. In other words, the maintenance personnel do not need to peek at the vibration isolating member 15 from above in order to confirm the status of the buffer member 31 and the status of the buffer member 32. Even if Figure 4 Even when the upper member 24 is arranged right above the vibration isolating member 15 as in the illustrated example, the state of the buffer member 31 and the state of the buffer member 32 can be checked from the front side.

[0072] Similarly, in the example shown in this embodiment, a gap is formed between the plate member 45 provided with the buffer member 31 and the plate member 50 provided with the buffer member 33. Therefore, when maintenance personnel install the vibration isolator 15 on the ceiling member 25, they can visually or manually confirm the status of the buffer member 31 and the status of the buffer member 32 through this gap. In other words, maintenance personnel do not need to peek at the vibration isolator 15 from above to confirm the status of the buffer member 31 and the status of the buffer member 32. Even if the upper member 24 is arranged directly above the vibration isolator 15, the status of the buffer member 31 and the status of the buffer member 32 can be confirmed from the front side.

[0073] In this embodiment, if Figure 3 , an example is described in which the buffer member 31 is opposite to the central portion of the surface 22a of the column 22 when viewed from above. The buffer member 31 may be arranged closer to the buffer member 32 than to the buffer member 33. In this case, the gap formed between the plate member 45 and the plate member 50 can be increased, making it easier to check the state of the buffer member 31. Similarly, the buffer member 31 may be arranged closer to the buffer member 33 than to the buffer member 32. In this case, the gap formed between the plate member 45 and the plate member 48 can be increased, making it easier to check the state of the buffer member 31.

[0074] In this embodiment, an example is described in which the plate member 49 of the arm 35 and the plate member 51 of the arm 36 are placed on the plate member 46 of the arm 34. Alternatively, the plate member 46 of the arm 34 may be placed on the plate member 49 of the arm 35 and the plate member 51 of the arm 36. In this case, the plate member 46 may also be rectangular. This facilitates the manufacture of the arm 34.

[0075] Figure 20 It is a plan view showing another example of the car 1. Figure 20 The example in which optional equipment such as air conditioning equipment is installed above the car chamber 11 is shown. When optional equipment is placed above the car chamber 11, the upper member 24 of the frame 12 needs to be arranged so that it does not interfere with the optional equipment. That is, when the car 1 is equipped with optional equipment, the upper member 24 is often arranged at a higher position than when the car 1 is not equipped with optional equipment. In addition, Figure 20 (a) shows an example in which the upper member 24 has a square ring shape in a plan view. Figure 20 (b) shows an example in which a portion of the members constituting the upper member 24 that is parallel to the X axis is arranged directly above the vibration isolators 15 and 16 .

[0076] Figure 21 yes Figure 20The car 1 shown is Figure 3 Quite a picture. Figure 22 yes Figure 20 The car 1 shown is Figure 4 Quite a picture. Figure 3 as well as Figure 4 In the example shown, the vibration isolating member 15 faces a connecting member 26 for connecting to the upper member 24 in the column 22. That is, the surfaces 22a to 22c are surfaces of the connecting member 26.

[0077] On the other hand, Figure 21 as well as Figure 22 In the example shown, the vibration isolator 15 faces the column member 27 extending downward from the connecting member 26 in the column 22. That is, the surfaces 22a to 22c are the surfaces of the column member 27. The column member 27 is slightly thinner than the connecting member 26. Therefore, Figure 21 as well as Figure 22 In the example shown, Figure 3 as well as Figure 4 Compared with the example shown, it is necessary to move the buffer member 31 in the -X direction, the buffer member 32 in the -Y direction, and the buffer member 33 in the Y direction. In the example shown in this embodiment, such position adjustment can be easily performed.

[0078] Figure 23 15 is a top view showing another example of the vibration isolating member 15. Figure 23 In the example shown, the vibration isolator 15 includes a support device 43 in addition to the buffer members 31 to 33, arms 34 to 36, a bottom plate 37 (not shown), nuts 38 to 39 (not shown), and bolts 41 to 42. Figure 23 In the illustrated example, the upper pad 40 is not shown, but the vibration isolator 15 may include a pad similar to the upper pad 40. By including a pad similar to the upper pad 40, the force holding the arms 35 and 36 can be increased.

[0079] exist Figure 23 In the example shown, arm 34 includes plate member 45, plate member 46, and reinforcement 47, as well as plate member 58. Plate member 58 is perpendicular to the X-axis. In other words, plate member 58 is arranged parallel to plate member 45. Plate member 46 is provided between plate member 45 and plate member 58.

[0080] Figure 24 4 is a plan view showing the support device 43. The support device 43 includes a support body 59, a pair of adjustment bolts 60, a pair of adjustment bolts 61, and a pair of adjustment bolts 62.

[0081] The support body 59 is formed by bending a flat plate. The support body 59 includes, for example, a base plate 63 and retaining plates 64 to 66. A pair of through-holes 63a and a pair of through-holes 63b are formed in the base plate 63. The through-holes 63a and 63b are aligned in the Y direction.

[0082] A retaining plate 64 extends upward from one end of the base plate 63. The retaining plate 64 is perpendicular to the X-axis. The adjusting bolt 60 is retained on the retaining plate 64 so as to be displaceable along the X-axis. The retaining plate 64 is disposed opposite the plate member 58. The tip of the adjusting bolt 60 abuts against the plate member 58.

[0083] A retaining plate 65 extends upward from the other end of the base plate 63. The retaining plate 65 is perpendicular to the Y-axis. The adjustment bolt 61 is retained by the retaining plate 65 so as to be displaceable along the Y-axis. The retaining plate 65 is positioned so as to face the plate member 48 of the arm 35. The tip of the adjustment bolt 61 abuts against the plate member 48.

[0084] A retaining plate 66 extends upward from the other end of the base plate 63. The retaining plate 66 is perpendicular to the Y-axis. The adjustment bolt 62 is retained by the retaining plate 66 so as to be displaceable along the Y-axis. The retaining plate 66 is positioned so as to face the plate member 50 of the arm 36. The tip of the adjustment bolt 62 abuts against the plate member 50.

[0085] exist Figure 23 In the example shown, the support body 59 is placed on the ceiling member 25 so that the bottom plate 63 faces the upper surface 11a of the car chamber 11. The arm 34 is placed on the bottom plate 63 of the support body 59. As a result, the through-hole 49a, the through-hole 46a, the through-hole 63a, and the through-hole 37c are arranged vertically. The bolt 41 penetrates the arm 35, the arm 34, the support device 43, the ceiling member 25, and the bottom plate 37 from above and is screwed into the nut 38. Furthermore, the through-hole 51a, the through-hole 46b, the through-hole 63b, and the through-hole 37d are arranged vertically. The bolt 42 penetrates the arm 36, the arm 34, the support device 43, the ceiling member 25, and the bottom plate 37 from above and is screwed into the nut 39.

[0086] in the case of Figure 23 In the example shown, when the buffer component 31 receives a force from the surface 22a, the force is transmitted to the retaining plate 64 of the support body 59 via the adjusting bolt 60. The force borne by the buffer component 31 can be dispersed to the support body 59. Similarly, when the buffer component 32 receives a force from the surface 22b, the force is transmitted to the retaining plate 65 of the support body 59 via the adjusting bolt 61. The force borne by the buffer component 32 can be dispersed to the support body 59. When the buffer component 33 receives a force from the surface 22c, the force is transmitted to the retaining plate 66 of the support body 59 via the adjusting bolt 62. The force borne by the buffer component 33 can be dispersed to the support body 59. Therefore, if it is Figure 23 In the example shown, the strength of the vibration isolating member 15 can be increased.

[0087] Furthermore, the adjustment screw 60 is an example of a means for transmitting the force received by the buffer member 31 from the surface 22a to the support body 59. Similarly, the adjustment screw 61 is an example of a means for transmitting the force received by the buffer member 32 from the surface 22b to the support body 59. The adjustment screw 62 is an example of a means for transmitting the force received by the buffer member 33 from the surface 22c to the support body 59.

[0088] Figure 25 It is a plan view showing another example of the vibration isolating member 15 . Figure 25 The example shown is similar to Figure 23 The example shown differs in the adjusting screw 61 and the adjusting screw 62 .

[0089] exist Figure 25 In the example shown, the one of the pair of adjustment bolts 61 that is closer to the buffer member 32 is denoted by reference numeral 61a, and the other one that is farther from the buffer member 32 is denoted by reference numeral 61b. Figure 23 In the illustrated example, the adjusting bolt 61 a is held by the holding plate 65 so as to be displaceable along the Y-axis. The front end of the adjusting bolt 61 a abuts against the plate member 48 .

[0090] The adjustment bolt 61b is held on the plate member 48 so that it can be displaced along the Y-axis. Specifically, the tip of the adjustment bolt 61b is screwed into a nut welded to the plate member 48. The adjustment bolt 61b passes through the retaining plate 65. The head of the adjustment bolt 61b faces the surface 65a of the retaining plate 65. The surface 65a faces the Y-direction.

[0091] Likewise, in Figure 25 In the example shown, the one of the pair of adjustment bolts 62 that is closer to the buffer member 33 is denoted by reference numeral 62a, and the other one that is farther from the buffer member 33 is denoted by reference numeral 62b. Figure 23 In the illustrated example, the adjustment bolt 62 a is held by the holding plate 66 so as to be displaceable along the Y-axis. The front end of the adjustment bolt 62 a abuts against the plate member 50 .

Specifically, the tip of the adjustment bolt 62b is screwed into a nut welded to the plate member 50. The adjustment bolt 62b passes through the retaining plate 66. The head of the adjustment bolt 62b faces the surface 66a of the retaining plate 66. The surface 66a faces the -Y direction.

[0093] exist Figure 25In the example shown, when the buffer member 32 is subjected to a force in the Y direction, the adjustment bolt 61b is pulled in the -Y direction by the plate member 48 with the tip of the adjustment bolt 61a as a fulcrum. Therefore, when the buffer member 32 is subjected to a force from the surface 22b, this force is transmitted to the retaining plate 65 of the support body 59 via the adjustment bolt 61b. This allows the force applied to the buffer member 32 to be distributed across the support body 59. Similarly, when the buffer member 33 is subjected to a force in the -Y direction, the adjustment bolt 62b is pulled in the Y direction by the plate member 50 with the tip of the adjustment bolt 62a as a fulcrum. Therefore, when the buffer member 33 is subjected to a force from the surface 22c, this force is transmitted to the retaining plate 66 of the support body 59 via the adjustment bolt 62b. This allows the force applied to the buffer member 33 to be distributed across the support body 59.

[0094] Figure 26 15 is a top view showing another example of the vibration isolating member 15. Figure 26 In the illustrated example, the vibration isolator 15 includes cushioning members 31 to 33, arms 34 to 36, a bottom plate 37 (not shown), nuts 38 to 39 (not shown), and bolts 41 to 42.

Plate member 46 extends further in the X-direction than one end of arm 35 and one end of arm 36. Retaining plate 71 extends upward from one end of the portion of plate member 46 extending in the X-direction. Retaining plate 71 is perpendicular to the X-axis. In other words, retaining plate 71 is arranged parallel to plate member 45.

[0096] The plate member 46 extends further in the Y direction than one end of the arm 35. A retaining plate 72 extends upward from one end of the portion of the plate member 46 that extends in the Y direction. The retaining plate 72 is perpendicular to the Y axis. The adjustment bolt 69 is retained by the retaining plate 72 so as to be displaceable along the Y axis. The retaining plate 72 is positioned so as to face the plate member 48 of the arm 35. The tip of the adjustment bolt 69 abuts against the plate member 48.

[0097] The plate member 46 extends further in the -Y direction than one end of the arm 36. A retaining plate 73 extends upward from one end of the portion of the plate member 46 extending in the -Y direction. The retaining plate 73 is perpendicular to the Y-axis. The retaining plate 73 is arranged parallel to the retaining plate 72. The adjustment bolt 70 is retained by the retaining plate 73 so as to be displaceable along the Y-axis. The retaining plate 73 is arranged so as to face the plate member 50 of the arm 36. The tip of the adjustment bolt 70 abuts against the plate member 50.

[0098] In addition to the plate member 48 and the plate member 49, the arm 35 also includes a retaining plate 74. The retaining plate 74 is perpendicular to the X-axis. The retaining plate 74 is arranged so as to be opposite to the retaining plate 71. The adjustment bolt 67 is retained on the retaining plate 74 so as to be displaceable along the X-axis. Specifically, the front end portion of the adjustment bolt 67 is screwed into a nut welded to the retaining plate 74. The adjustment bolt 67 passes through a long hole (not shown) formed in the retaining plate 71. The long hole has a long side in the Y direction. The head of the adjustment bolt 67 is opposite to the surface 71a of the retaining plate 71. The surface 71a faces the X direction.

[0099] In addition to the plate member 50 and the plate member 51, the arm 36 also includes a retaining plate 75. The retaining plate 75 is perpendicular to the X-axis. The retaining plate 75 is arranged parallel to the retaining plate 74. In addition, the retaining plate 75 is arranged so as to be opposite to the retaining plate 71. The adjustment bolt 68 is retained on the retaining plate 75 in a manner that allows displacement along the X-axis. Specifically, the front end portion of the adjustment bolt 68 is screwed into a nut that is welded and fixed to the retaining plate 75. The adjustment bolt 68 passes through a long hole (not shown) formed in the retaining plate 71. The long hole has a long side in the Y direction. The head of the adjustment bolt 68 is opposite to the surface 71a of the retaining plate 71.

[0100] exist Figure 26 In the illustrated example, when the cushioning member 31 receives a force from the surface 22a, the force is transmitted to the retaining plate 74 of the arm 35 via the adjustment screw 67. Furthermore, when the cushioning member 31 receives a force from the surface 22a, the force is transmitted to the retaining plate 75 of the arm 36 via the adjustment screw 68. This allows the force applied to the cushioning member 31 to be distributed to both the arm 35 and the arm 36.

[0101] Similarly, when the buffer member 32 receives a force from the surface 22b, the force is transmitted to the retaining plate 72 of the arm 34 via the adjustment bolt 69. This allows the force received by the buffer member 32 to be distributed to the arm 34. When the buffer member 33 receives a force from the surface 22c, the force is transmitted to the retaining plate 73 of the arm 34 via the adjustment bolt 70. This allows the force received by the buffer member 33 to be distributed to the arm 34. Therefore, if Figure 26 In the example shown, the strength of the vibration isolating member 15 can be increased.

[0102] Furthermore, adjustment screw 67 is an example of a means for transmitting the force received by buffer member 31 from surface 22a to arm 35. Adjustment screw 68 is an example of a means for transmitting the force received by buffer member 31 from surface 22a to arm 36.
