[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the accompanying drawings, elements having substantially the same function or structure are labeled with the same reference numerals, and repeated descriptions are omitted.

[0023] 1. Implementation Method

[0024] [elevator]

[0025] First, refer to Figure 1 The structure of an elevator according to one embodiment of the present invention will be described.

[0026] Figure 1 This is a schematic diagram of an elevator according to one embodiment.

[0027] like Figure 1 As shown, the elevator includes a traction machine 1, a main hoist 2, an elevator car 3, a counterweight 5, and pulleys 6. The elevator car 3 includes a pair of car pulleys 4A and 4B. The elevator car 3 moves up and down in the shaft 100 as the main hoist 2, which is wound around the pair of car pulleys 4A and 4B, moves.

[0028] The traction machine 1 is a device that winds up the main hoisting cable 2 to raise and lower the elevator car 3. The traction machine 1 is located at the upper part of the hoistway 100. One end and the other end of the main hoisting cable 2 are fixed to the uppermost part of the hoistway 100. The main hoisting cable 2 is wound around a pair of car pulleys 4A and 4B, the traction machine 1, and the pulley 6.

[0029] The elevator car 3 is guided up and down by a pair of guide rails (not shown). A pair of car pulleys 4A and 4B are located on the underside of the elevator car 3. The counterweight 5 is a counterweight used to balance the mass of the elevator car 3 and reduce the load on the traction machine 1. When the traction machine 1 winds up the main hoisting cable 2, the counterweight 5 moves up and down in the opposite direction to the elevator car 3. The pulley 6 is located on top of the counterweight 5 and moves up and down together with the counterweight 5.

[0030] [Elevator car]

[0031] Next, refer to Figure 2 The structure of elevator car 3 will be described.

[0032] Figure 2 This is a three-dimensional view showing the exterior of elevator car 3.

[0033] In this embodiment, the front-back, up-down, and left-right directions are defined based on the line of sight of the elevator user opposite the elevator car 3. At this time, from the elevator user's perspective, the side closer to the front is the front direction, the side deeper is the rear direction, the upper side is the upper direction, the lower side is the lower direction, the left side is the left direction, and the right side is the right direction.

[0034] like Figure 2 As shown, the elevator car 3 includes a car frame 7 and a car compartment 8 disposed inside the car frame 7. The car compartment 8 has an internal space for loading goods and people. The car compartment 8 is formed by a car floor 12, side panels 13, and a top panel 15. The car floor 12 and the top panel 15 are arranged opposite each other in the vertical direction, separated by the aforementioned space. The side panels 13 are arranged to surround the aforementioned space on all four sides, except for the portion of the car door 18.

[0035] The car frame 7 is formed as a rectangle that is elongated when viewed from the front-to-back direction. The car frame 7 is arranged in a square manner, surrounding the car compartment 8 in the left-right and up-down directions. The car frame 7 has an upper frame 9 disposed above the car compartment 8 and a lower frame 10 disposed below the car compartment 8 (see reference). Figure 3 ) and a pair of longitudinal frames 11A and 11B arranged on the left and right sides of the car compartment 8.

[0036] The upper frame 9 is a component that extends relatively far in the left-right direction. The upper frame 9 is horizontally mounted between the upper ends of a pair of vertical frames 11A and 11B. One end of the upper frame 9 in the longitudinal direction is fixed to the upper end of the vertical frame 11A, and the other end of the upper frame 9 in the longitudinal direction is fixed to the upper end of the vertical frame 11B. Thus, the upper ends of the pair of vertical frames 11A and 11B are connected by the upper frame 9.

[0037] A pair of longitudinal frames 11A and 11B are arranged opposite each other in the left-right direction. Each longitudinal frame 11A and 11B is a component that extends relatively long in the vertical direction. Each longitudinal frame 11A and 11B is movably supported by the aforementioned pair of guide rails. The guide rails are long strip-shaped components that are vertically mounted to the wall of the shaft 100.

[0038] The lower frame 10 is positioned opposite the upper frame 9, separated by the car compartment 8. The lower frame 10 is a generally rectangular parallelepiped component that extends relatively long in the left-right direction (see reference). Figure 3 The lower frame 10 is horizontally mounted between the lower ends of a pair of vertical frames 11A and 11B. One end of the lower frame 10 along its length is fixed to the lower end of the vertical frame 11A, and the other end of the lower frame 10 along its length is fixed to the lower end of the vertical frame 11B. Thus, the lower ends of the pair of vertical frames 11A and 11B are connected by the lower frame 10.

[0039] The lower frame 10 supports the car floor 12 via a pair of floor support beams 14A and 14B. The pair of floor support beams 14A and 14B are beams that support the car floor 12. Vibration damping sections 20 are provided at both ends of the floor support beams 14A and 14B along their length. The vibration damping sections 20 are components that suppress vibrations in the car compartment 8, including the car floor 12. The car floor 12 is supported by the pair of floor support beams 14A and 14B via multiple (four in this example) vibration damping sections 20.

[0040] Floor support beam 14A is located at one end (right end) of the lower frame 10 along its length. Floor support beam 14B is located at the other end (left end) of the lower frame 10 along its length (see reference). Figure 3 Furthermore, each floor support beam 14A and 14B, while mounted on the lower frame 10, is fixed to the upper surface of the lower frame 10 by bolts (not shown). Each floor support beam 14A and 14B is arranged horizontally at a right angle to the lower frame 10. Specifically, the lower frame 10 is arranged parallel to the left-right direction, and each floor support beam 14A and 14B is arranged parallel to the front-back direction.

[0041] A car door 18 is provided at the front of the car compartment 8. The car door 18 is configured to open and close in the left and right directions. A pair of car pulleys 4A and 4B (4B refers to...) are provided on the lower side of the car compartment 8. Figure 1The car pulleys 4A and 4B are positioned forward of the longitudinal frames 11A and 11B. One car pulley 4A is mounted on the floor support beam 14A, and the other car pulley 4B is mounted on the floor support beam 14B.

[0042] [Vibration isolation department]

[0043] Next, refer to Figure 3 and Figure 4 The structure of the vibration damping unit 20 will be described.

[0044] Figure 3 This is an explanatory diagram showing a pair of floor support beams 14A and 14B. Figure 4 This is a three-dimensional view of the car floor 12 as seen from below.

[0045] The anti-vibration part 20 has: Figure 3 The four helical springs 20A shown; the first spring base 20B mounted on the bottom surface of the floor support beams 14A and 14B; and mounted on... Figure 4 The second spring base 20C is shown on the bottom surface of the car floor 12.

[0046] like Figure 3 As shown, the coil spring 20A is an elastic component for vibration damping. The first spring base 20B and the second spring base 20C are plate-shaped components. The first spring base 20B is provided with four spring receiving holes (not shown) to accommodate one end of four coil springs 20A. The spring receiving holes of the first spring base 20B are circular. The diameter of the spring receiving holes of the first spring base 20B is larger than the diameter of the coil springs 20A. The gap between the spring receiving holes of the first spring base 20B and the coil springs 20A is set to the size required to adjust the position of the car chamber 8.

[0047] like Figure 4 As shown, the second spring base 20C is provided with four spring receiving holes 20D for accommodating the other ends of four helical springs 20A. The spring receiving holes 20D are circular. The diameter of the spring receiving holes 20D is set to be approximately the same as the diameter of the helical springs 20A. The helical springs 20A are fitted into the spring receiving holes 20D and move together with the second spring base 20C and the car chamber 8.

[0048] like Figure 4 As shown, the car floor 12 has a rectangular floor component 12A. The two short sides of the floor component 12A are approximately orthogonal to the front-rear direction, and the two long sides are approximately orthogonal to the left-right direction. A car door sill 12B is installed on one of the short sides of the floor component 12A facing forward. The car door sill 12B is positioned at a predetermined distance from the opening door sill (not shown) provided in the hoistway 100.

[0049] A floor frame component 12C is provided on the rearward short side of the floor component 12A. In addition, floor frame components 12D and 12E are provided on the two long sides of the floor component 12A, respectively. The lower parts of three side plates 13, excluding the side plate 13 on which the car door 18 is installed, are fixed on the aforementioned accommodating space side (inner side) of the floor frame components 12C to 12E.

[0050] The car compartment 8 is supported by a pair of floor support beams 14A and 14B via vibration damping parts 20. This suppresses vibration of the car compartment 8. Furthermore, the elevator car 3 includes a pair of anti-sway parts 31A and 31B to suppress swaying of the car compartment 8 in the forward and backward directions (see reference). Figure 5 The pair of anti-sway parts 31A and 31B also serve as the position adjustment mechanism for the car compartment 8. Next, refer to... Figure 5 and Figure 6 The structure of a pair of anti-shake parts 31A and 31B will be described.

[0051] [A pair of vertical frames]

[0052] Next, refer to Figure 5 The structure of a pair of vertical frames 11A and 11B is explained.

[0053] Figure 5 This is a 3D view of the elevator car 3 with the top panel 15 and side panel 13 removed.

[0054] like Figure 5 As shown, the longitudinal frame 11A has a longitudinal frame body 21, a connecting member 22, and a fitting portion 23. The longitudinal frame body 21 extends relatively long in the vertical direction. The longitudinal frame body 21 has two opposing sides 21A and 21B in the front-rear direction and a main body plate 21C connected to the two sides 21A and 21B. The main body plate 21C is opposite to the car compartment 8. The two sides 21A and 21B protrude substantially vertically from both ends of the main body plate 21C toward the opposite side of the car compartment 8.

[0055] The connecting component 22 is positioned directly above the car's lower pulley 4A, connecting the longitudinal frame 11A and the floor support beam 14A. Like the longitudinal frame body 21, the connecting component 22 is constructed of a bent component. The upper end of the connecting component 22 is set at approximately the same height as the lower surface of the car floor 12. The connecting component 22 is fixed to the side 21A of the longitudinal frame body 21 using bolts (screws). Furthermore, the connecting component 22 is fixed to the floor support beam 14A via an intermediate component 24.

[0056] The fitting part 23 is an integral structure obtained by bending a metal plate. The fitting part 23 is fixed to the lower part of the longitudinal frame body 21. The fitting part 23 has a pair of wall panels facing each other in the front-to-back direction and a bottom plate having a plane substantially perpendicular to the vertical direction. The lower frame 10 (see reference) is fitted into the fitting part 23 from above. Figure 5 One end of the length direction of ).

[0057] The longitudinal frame 11B has a longitudinal frame body 25, a connecting part 26, and a fitting part 27 (see reference). Figure 3 The main body 25 of the longitudinal frame has the same structure as the main body 21 of the longitudinal frame 11A described above, and has two sides 25A and 25B and a main body plate 25C connected to the two sides 25A and 25B.

[0058] Connecting component 26 is located on the car lower pulley 4B (see reference) Figure 3 Directly above, place the longitudinal frame 11B and the floor support beam 14B (refer to...) Figure 3 The connecting component 26, like the longitudinal frame body 21, is composed of a bent component. The upper end of the connecting component 26 is higher than the upper surface of the car floor 12. The connecting component 26 is fixed to the side 25A of the longitudinal frame body 25 using bolts (screws). In addition, the connecting component 26 is fixed to the floor support beam 14B via an intermediate component (not shown).

[0059] The fitting portion 27 has the same shape as the fitting portion 23 of the longitudinal frame 11A described above. The fitting portion 27 is fixed to the lower part of the longitudinal frame body 25. The fitting portion 27 has a pair of wall panels facing each other in the front-rear direction and a bottom plate having a plane substantially perpendicular to the vertical direction. The lower frame 10 (see reference 10) is fitted into the fitting portion 27 from above. Figure 5 One end of the length direction of ).

[0060] [A pair of anti-shake parts]

[0061] Next, refer to Figure 5 and Figure 6 The pair of anti-sway parts 31A and 31B in the car compartment 8 will be described.

[0062] Figure 6 This is an explanatory diagram showing a portion of the side of the elevator car 3 with the top plate 15 and side plate 13 removed, enlarged.

[0063] like Figure 5 and Figure 6 As shown, the anti-shaking part 31A includes a rubber plate 32 as an elastic body and a metal bracket 33 supporting the rubber plate 32. The rubber plate 32 is formed in an L-shape. The rubber plate 32 represents a specific example of the rubber component of the present invention.

[0064] The bracket 33 of the anti-sway part 31A is positioned in front of the longitudinal frame 11A in the front-rear direction. Like the rubber plate 32, the bracket 33 is L-shaped and has a fixing part 33a fixed to the car compartment 8 and a counter part 33b opposite to the longitudinal frame 11A of the car frame 7 in the front-rear direction.

[0065] The fixing part 33a of the bracket 33 is fixed to the floor frame component 12D of the car floor 12 by two bolts 37. The threaded through holes through which the two bolts 37 of the fixing part 33a pass are formed into a roughly elliptical shape that is longer in the horizontal direction. The rubber plate 32 is located between the opposing part 33b and the longitudinal frame 11A, and between the car compartment 8 and the longitudinal frame 11A. The opposing part 33b of the bracket 33 presses the rubber plate 32 toward the side 21A of the longitudinal frame 11A.

[0066] The anti-sway section 31B has the same structure as the anti-sway section 31A, including a rubber plate 35 and a bracket 36. The rubber plate 35 represents a specific example of the rubber component of the present invention. The bracket 36 of the anti-sway section 31B is positioned rearward in the longitudinal direction than the longitudinal frame 11A. The bracket 36 has a fixing portion 36a fixed to the car compartment 8 and a counter portion 36b opposite to the longitudinal frame 11A of the car frame 7 in the longitudinal direction.

[0067] The fixing part 36a of the bracket 36 is fixed to the floor frame component 12D of the car floor 12 by two bolts 37. The threaded through holes through which the two bolts 37 of the fixing part 36a pass are formed into a generally elliptical shape that is longer in the horizontal direction. The rubber plate 35 is located between the opposing part 36b and the longitudinal frame 11A, and between the car compartment 8 and the longitudinal frame 11A. The opposing part 36b of the bracket 36 presses the rubber plate 35 toward the side 21B of the longitudinal frame 11A.

[0068] Elevator car 3 has a function for adjusting elevator car 3 relative to car frame 7 (see reference). Figure 2 The position adjustment mechanism consists of the aforementioned brackets 33 and 36 and two lifting bolts 34. The two lifting bolts 34 pass through the opposite portions 33b and 36b of the brackets 33 and 36, and abut against the sides 21A and 21B of the longitudinal frame 11A, respectively.

[0069] When the front end of the lifting bolt 34 of the opposite portion 33b of the through bracket 33 is pressed toward the side portion 21A of the longitudinal frame 11A, the length of the gap between the opposite portion 33b and the side portion 21A increases. As a result, the car chamber 8 moves forward relative to the longitudinal frame 11A (car frame 7). On the other hand, when the front end of the lifting bolt 34 of the opposite portion 36b of the through bracket 36 is pressed toward the side portion 21B of the longitudinal frame 11A, the length of the gap between the opposite portion 36b and the side portion 21B increases. As a result, the car chamber 8 moves rearward relative to the longitudinal frame 11A (car frame 7).

[0070] [Elevator car installation work]

[0071] Next, the installation of elevator car 3 will be explained.

[0072] The lower frame 10 of the elevator car 3, a pair of floor support beams 14A and 14B, and the car floor 12 are assembled together and moved into the installation site as the lower part of the elevator car assembly.

[0073] When assembling the lower part of the elevator car in a factory or similar facility, the bottom surface of the car floor 12 is facing upwards, and the second spring base 20C is installed on its bottom surface. Then, one end of the coil spring 20A is inserted into the spring receiving hole 20D of the second spring base 20C.

[0074] Next, the pair of floor support beams 14A and 14B, with the first spring base 20B installed, are positioned above the car floor 12, and the other end of the coil spring 20A is inserted into the spring receiving hole of the first spring base 20B. Then, the car floor 12 and the pair of floor support beams 14A and 14B are temporarily secured using temporary fixing components (not shown). Then, the lower part of the elevator car assembly is flipped vertically so that the car floor 12 faces upwards.

[0075] The diameter of the spring receiving hole 20D is set to be approximately the same as the diameter of the coil spring 20A. Therefore, when the other end of the coil spring 20A is inserted into the spring receiving hole of the first spring base 20B, the position of the coil spring 20A can be kept from shifting. As a result, the assembly of the lower part of the elevator car can be performed efficiently.

[0076] When installing the elevator car 3, firstly, a pair of longitudinal frames 11A and 11B are installed on a guide rail (not shown). At this time, the pair of longitudinal frames 11A and 11B are fixed to the guide rail. Thus, after the elevator car 3 is assembled, the car frame 7 can move relative to the guide rail.

[0077] Next, the lower elevator car assembly is positioned above the fitting portions 23 and 27 of the pair of longitudinal frames 11A and 11B. Then, the lower elevator car assembly is lowered so that both ends of the lower frame 10 in the longitudinal direction fit into the fitting portions 23 and 27 of the pair of longitudinal frames 11A and 11B. Next, the lower frame 10 is secured to the fitting portions 23 and 27 using bolts (screws). Thus, the lower elevator car assembly is installed onto the pair of longitudinal frames 11A and 11B.

[0078] Next, four side panels 13 are fixed to the car floor 12, and a top panel 15 is fixed on top of the four side panels 13. Thus, the car compartment 8 is assembled (see reference). Figure 2 Next, bolts (screws) are used to fix the two ends of the upper frame 9 along its length to the upper ends of the longitudinal frames 11A and 11B. Thus, the car frame 7 is assembled, and the installation of the elevator car 3 is completed.

[0079] [Elevator car position adjustment operation]

[0080] Next, the position adjustment operation of elevator car 3 will be explained.

[0081] The position adjustment of the elevator car 3 can be performed on the car floor 12 when the lower part of the elevator car assembly is installed on a pair of longitudinal frames 11A and 11B, or it can be performed after the elevator car 3 is assembled.

[0082] The elevator car 3 is supported by a pair of floor support beams 14A and 14B via four vibration damping units 20. The pair of floor support beams 14A and 14B are supported by the lower frame 10 of the car frame 7. As described above, the vibration damping unit 20 includes: a coil spring 20A; a first spring base 20B mounted on the floor support beams 14A and 14B; and a second spring base 20C mounted on the car floor 12. The diameter of the spring receiving hole in the first spring base 20B is larger than the diameter of the coil spring 20A. Therefore, the elevator car 3 can move horizontally even without lifting the elevator car 3 relative to the floor support beams 14A and 14B.

[0083] When adjusting the position of the elevator car 3, first, remove the rubber plates 32 and 35 of the pair of anti-shaking parts 31A and 31B (refer to...). Figure 6 Then, as the elevator car 3 moves forward, the front end of the lifting bolt 34 of the through bracket 33 is pressed against the side 21A of the longitudinal frame 11A. At this time, the front end of the lifting bolt 34 of the through bracket 36 moves away from the side 21B of the longitudinal frame 11A. As a result, the elevator car 3 moves forward.

[0084] On the other hand, when the elevator car 3 moves rearward, the front end of the lifting bolt 34 of the through bracket 36 is pressed towards the side 21B of the longitudinal frame 11A. At this time, the front end of the lifting bolt 34 of the through bracket 33 moves away from the side 21A of the longitudinal frame 11A. As a result, the elevator car 3 moves rearward. In this way, the elevator car 3 (car floor 12) can be easily moved by pushing the lifting bolt 34, and the position adjustment of the elevator car 3 in the front-rear direction can be easily performed.

[0085] After adjusting the position of the elevator car 3, remove brackets 33 and 36 from the car floor 12. Then, position the rubber plate 32 between the opposing portion 33b of the bracket 33 and the side portion 21A of the longitudinal frame 11A. Next, position the bracket 33 at the position where the rubber plate 32 is pressed against the side portion 21A at the opposing portion 33b, and use two bolts 37 to fix the fixing portion 33a of the bracket 33 to the car floor 12.

[0086] Furthermore, the rubber sheet 35 is positioned between the opposing portion 36b of the bracket 36 and the side portion 21B of the longitudinal frame 11A. Then, the bracket 36 is positioned at the point where the rubber sheet 35 is pressed against the side portion 21B at the opposing portion 36b, and the fixing portion 36a of the bracket 36 is fixed to the car floor 12 using two bolts 37. This suppresses the forward and backward swaying of the elevator car 3.

[0087] In addition, the lifting bolt 34 can be stored together with the elevator car 3 in a state where it passes through the brackets 33 and 36. Alternatively, it can be removed from the brackets 33 and 36 and stored separately from the elevator car 3.

[0088] 2. Summary

[0089] As explained above, the elevator car 3 of the above embodiment includes a car compartment 8, a car frame 7, floor support beams 14A and 14B (support beams), brackets 33 and 36, and a lifting bolt 34. The car compartment 8 has side panels 13 that surround the four sides in the left-right and front-back directions when viewed from the lobby side of the building. The car frame 7 surrounds the car compartment 8 in the left-right and up-down directions. The floor support beams 14A and 14B are fixed to the car frame 7 and support the car compartment 8. The brackets 33 and 36 have fixing portions 33a and 36a that are fixed to the car compartment 8 and opposing portions 33b and 36b that are opposite to the car frame 7 in the front-back direction. The lifting bolt 34 passes through the opposing portions 33b and 36b of the brackets 33 and 36 and abuts against the car frame 7. As a result, the elevator car 3 can be easily moved in the front-back direction, and the position adjustment of the elevator car 3 can be easily performed.

[0090] Furthermore, in the above embodiment, the car chamber 8 has a car floor 12 and a top plate 15 that are opposite each other in the vertical direction, and the fixing parts 33a and 36a of the brackets 33 and 36 are fixed to the car floor 12. Therefore, when adjusting the position of the elevator car 3, the elevator car 3 can move stably. In addition, the elevator car 3 can be assembled after adjusting the position of the car floor 12, making the position adjustment operation of the elevator car 3 easier.

[0091] Furthermore, the elevator car 3 in the above embodiment also includes a vibration damping part 20 located between the floor support beams 14A and 14B (support beams) and the car floor 12. The vibration damping part 20 includes: a first spring base 20B (first base) disposed on the floor support beams 14A and 14B; a second spring base 20C (second base) disposed on the car floor 12; and a coil spring 20A (elastic member) located between the first spring base 20B and the second spring base 20C (second base). The first spring base 20B has a spring receiving hole (receiving part) that accommodates the coil spring 20A in a manner that allows horizontal movement. Furthermore, the second spring base 20C has a spring receiving hole 20D (receiving part) that accommodates the coil spring 20A in a manner that prevents horizontal movement. Therefore, even without lifting the elevator car 3 relative to the floor support beams 14A and 14B, it can be moved in the horizontal direction.

[0092] Furthermore, the car frame 7 in the above embodiment includes: an upper frame 9 disposed above the car compartment 8; a lower frame 10 disposed below the car compartment 8; and a pair of longitudinal frames 11A and 11B disposed on the left and right sides of the car compartment 8. Floor support beams 14A and 14B (support beams) are fixed to the lower frame 10. Opposite portions 33b and 36b of brackets 33 and 36 are opposite to longitudinal frames 11A. Thus, the operation of lifting bolts 34 can be performed even without the operator entering the underside of the car floor 12. As a result, the safety of the elevator car 3 position adjustment operation can be improved.

[0093] Furthermore, the elevator car 3 in the above embodiment also includes rubber plates 32 and 35 (rubber components) located between the opposing portions 33b and 36b and the car frame 7 after adjusting the position of the car compartment 8. Thus, the brackets 33 and 36, which are components of the position adjustment mechanism, also serve as components of the anti-sway portions 31A and 31B. As a result, the position adjustment of the elevator car 3 in the forward and backward directions is easy, and the number of components can be reduced.

[0094] Furthermore, the elevator car 3 in the above embodiment has a bracket 33 (first bracket) and a bracket 36 (second bracket). Additionally, the elevator car 3 has a lifting bolt 34 (first lifting bolt) that passes through the opposing portion 33b of the bracket 33 and a lifting bolt 34 (second lifting bolt) that passes through the opposing portion 36b of the bracket 36. The opposing portion 33b faces the front surface (side 21A) of the car frame 7 in the forward-rear direction, and the opposing portion 36b faces the rear surface (side 21B) of the car frame 7 in the forward-rear direction. This allows the elevator car 3 to move easily forward and backward.

[0095] The elevator car and elevator of the present invention have been described above, including their effects. However, the elevator car and elevator of the present invention are not limited to the above-described embodiments and can be implemented in various modifications without departing from the spirit of the invention.

[0096] For example, in the above embodiment, a structure is adopted in which the brackets 33 and 36 of the fixed position adjustment mechanism are used in the floor frame component 12D of the car floor 12. However, as the elevator car of the present invention, a structure in which the bracket of the fixed position adjustment mechanism is used in the floor frame component 12E may also be adopted. Furthermore, as the position adjustment mechanism of the present invention, a structure in which the brackets are respectively provided on both sides (floor frame components 12D and 12E) in the left and right directions of the elevator car may also be adopted.

[0097] Furthermore, the above embodiment uses a helical spring as the elastic component of the vibration damping part 20. However, other spring components or rubber components, such as leaf springs, can also be used as the elastic component of the vibration damping part of the present invention.

[0098] Furthermore, the above-described embodiment employs a structure that allows the elevator car 3 to move horizontally even without lifting the elevator car, thanks to the presence of multiple vibration damping sections 20. However, the elevator car position adjustment mechanism of the present invention can also be applied to elevator cars that can move in the front-rear direction by being lifted relative to the floor support beam.

[0099] Furthermore, the above-described embodiments are detailed descriptions provided for ease of understanding of the present invention and are not necessarily limited to all structures described. Moreover, it is possible to add, delete, or replace other structures within a portion of the structure of the embodiments.

[0100] In addition, the terms “parallel” and “orthogonal” are used in this specification, but they do not only refer to strict “parallel” and “orthogonal”. They can refer to a state of “approximately parallel” or “approximately orthogonal” that includes “parallel” and “orthogonal” and is within the range in which they can perform their functions.
