[0031] The accompanying drawings illustrate the manner in which this disclosure is implemented. In the drawings, identical or equivalent parts are labeled with the same reference numerals, and repetitive descriptions are simplified or omitted where appropriate. Furthermore, this disclosure is not limited to the following embodiments; any modifications or omissions of any constituent elements of the embodiments are permissible without departing from the spirit of this disclosure.

[0032] Implementation Method 1

[0033] Figure 1 This is a perspective view of elevator 1 according to implementation method 1.

[0034] Elevator 1 is suitable for buildings with multiple floors. In buildings using elevator 1, a lifting channel 2 is provided. The lifting channel 2 is a space spanning multiple floors. The lifting channel 2 is surrounded by an inner wall 3. The inner wall 3 of the lifting channel 2 is a wall along the vertical direction. At each floor, a station (not shown) is provided. The station is a location adjacent to the lifting channel 2. Elevator 1 includes a winch 4, main hoisting cable 5, car 6, and counterweight 7.

[0035] The winch 4 is installed, for example, above or below the elevator shaft 2. For instance, if a machine room for the elevator 1 is located above the elevator shaft 2, the winch 4 can also be installed in the machine room. The winch 4 includes a motor that generates torque and a pulley that is driven to rotate by the motor.

[0036] The main sling 5 is wound around the pulley of the winch 4. The main sling 5 supports the load of the car 6 on one side of the winch 4. The main sling 5 supports the load of the counterweight 7 on the other side of the winch 4. Balance with the load of the car 6 applied to the main sling 5 on one side of the winch 4 is achieved by applying the load of the counterweight 7 to the main sling 5 on the other side of the winch 4. The main sling 5 moves under the torque generated by the motor of the winch 4, causing either the car 6 side or the counterweight 7 side to be wound up by the winch 4.

[0037] The car 6 is a device that transports users of the elevator 1 between multiple floors by traveling vertically within the hoisting channel 2. The car 6 and the counterweight 7 move in opposite directions vertically within the hoisting channel 2 in conjunction with the movement of the main hoisting cable 5 caused by the winch 4. The car 6 includes a car compartment 8, a car frame 9, baffles 10, and guide members 11.

[0038] The car compartment 8 is the device through which users enter. The car compartment 8 is, for example, rectangular in shape. An entrance 12 is provided in the car compartment 8 for users to move between the interior and exterior of the car compartment 8. The entrance 12 of the car compartment 8 is located on the side of the car compartment 8 facing the elevator station. In this example, the direction from the elevator shaft 2 towards the elevator station is defined as the front. That is, the entrance 12 of the car compartment 8 is located at the front of the car compartment 8. At the entrance 12 of the car compartment 8, a door (not shown) is provided to divide the interior and exterior of the car 6. Furthermore, in the following description, the direction from the elevator shaft 2 in the horizontal direction opposite to the elevator station is defined as the rear. The rearward-facing surface is defined as the rear. The direction in the horizontal direction perpendicular to the front and rear is defined as the side. The sideward-facing surface is defined as the side. In addition, when the car 6 moves vertically in the lifting channel 2, airflow is generated around the car 6 relative to the movement of the car 6. This airflow will be described below as airflow or wind.

[0039] The car frame 9 is the frame that supports the car compartment 8. The car frame 9 is, for example, a rectangular frame. The car frame 9 includes an upper beam 13, a pair of columns 14, and a lower beam 15. The upper beam 13 forms the upper part of the car frame 9. One column 14 forms the left side of the car frame 9. The other column 14 forms the right side of the car frame 9. The lower beam 15 forms the lower part of the car frame 9. One end of the main hoisting cable 5 is connected to the upper beam 13.

[0040] A baffle 10 is located below the front end of the car compartment 8. The baffle 10 is a portion that prevents users from rolling down the elevator shaft 2 from the landing on any floor if the car 6 cannot stop at its normal stopping position. The baffle 10 is formed of a plate-like member. The baffle 10 has a first surface 16 and a second surface 17. In this example, the first surface 16 and the second surface 17 are separated by a bend 18. The bend 18 is a crease along the left-right direction. The bend angle of the bend 18 is smaller than a right angle; that is, the angle formed by the first surface 16 and the second surface 17 is an obtuse angle. The first surface 16 is the surface above the bend 18. The first surface 16 is arranged with its surface facing forward in the up-down direction. That is, the first surface 16 is arranged parallel to the inner wall 3 of the elevator shaft 2. The second surface 17 is the surface below the bend 18. The second surface 17 is inclined backward at an obtuse angle to the first surface 16. That is, the lower end of the second surface 17 is located further back than the upper end. A first ventilation hole 19 is provided on the second surface 17. The first ventilation hole 19 is a hole through which air passes. The first ventilation hole 19 can also be composed of multiple holes. In this case, the arrangement of the multiple holes is not limited to... Figure 1 The configuration shown is correct. Alternatively, the first ventilation opening 19 can also be a slit or the like. A mesh or similar material can also be installed in the first ventilation opening 19.

[0041] The guide member 11 is disposed below the car compartment 8. The guide member 11 has a first panel 20. The first panel 20 is a plate-shaped member with its surface facing forward in a vertical direction. The first panel 20 is disposed in front of the baffle 10.

[0042] Figure 2 This is a cross-sectional view of the elevator car 6 of the elevator 1 according to embodiment 1.

[0043] Figure 2 It represents the cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0044] The first panel 20 is connected to the first surface 16 in front of the baffle 10. The lower end of the first panel 20 is positioned below the first surface 16 of the baffle 10. The lower end of the first panel 20 is positioned below the bent portion 18 of the baffle 10. The lower end of the first panel 20 is positioned below the first ventilation hole 19 of the baffle 10. The lower end of the first panel 20 is positioned above the lower end of the second surface 17 of the baffle 10. The first panel 20 has a structure that extends downward from a position above the first ventilation hole 19 at a position forward of the second surface 17.

[0045] Next, use Figure 3 and Figure 4 This describes the dimensions around the car 6 when the guide member 11 has been removed.

[0046] Figure 3 and Figure 4 This is a cross-sectional view of the car 6 without the guide component 11.

[0047] Figure 3 and Figure 4 The figure shows a cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0048] In addition, the corresponding parts of the car 6 without the guide member 11 and the car 6 of Embodiment 1 are marked with the same reference numerals.

[0049] like Figure 3 As shown, the baffle 10 is disposed below the front end of the car compartment 8. The baffle 10 has a first surface 16 and a second surface 17 separated by a bend 18.

[0050] like Figure 4As shown, the distance A between the first surface 16 of the baffle 10 and the inner wall 3 of the elevator shaft 2 is smaller than the distance B between the second surface 17 of the baffle 10 and the inner wall 3 of the elevator shaft 2. The path from below the car 6 to the area C between the car chamber 8 and the inner wall 3 of the elevator shaft 2 passes between the second surface 17 and the inner wall 3, and between the first surface 16 and the inner wall 3, thus becoming a gradually narrowing path. Area C is adjacent to a door provided in the car chamber 8. In area C, multiple components for opening and closing the door are arranged. Therefore, if the air velocity relative to the car chamber 8 increases in area C, the noise generated in front of the car chamber 8 due to the airflow may sometimes increase.

[0051] Next, use Figures 5A to 5C This illustrates an example of noise reduction based on the guide member 11.

[0052] Figure 5A This is a cross-sectional view of a car 6 that does not have a guide member 11 and does not have a first ventilation hole 19 on the baffle 10.

[0053] Figure 5B This is a cross-sectional view of the car 6 without the guide component 11.

[0054] Figure 5C This is a cross-sectional view of the car 6 in Embodiment 1.

[0055] Figures 5A to 5C The figure shows a cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0056] Because the baffle 10 is located below the car compartment 8, its impact on noise levels inside the car compartment 8 when the car 6 is moving upwards is minimal. Figures 5A to 5C The image shows an example of airflow around the car chamber 8 when the car 6 is moving downwards.

[0057] like Figure 5A As shown, because the front of the second surface 17 is tilted and faces downwards, the airflow from below that collides with the front of the second surface 17 rises along the surface of the second surface 17 where the first ventilation hole 19 is not formed. Since the interval A is smaller than the interval B, as the car 6 travels downwards, the airflow is guided by the baffle 10 to concentrate it from below the car chamber 8 into region C between the car chamber 8 and the inner wall 3 of the elevator shaft 2. As a result, the airflow velocity in region C relative to the car chamber 8 increases. At this time, the noise generated in front of the car chamber 8 due to the airflow increases.

[0058] like Figure 5BAs shown, when a first ventilation hole 19 is provided on the baffle 10, airflow can pass through the front and rear of the first ventilation hole 19. On the other hand, since the pressure difference before and after the first ventilation hole 19 is small, the amount of airflow passing through the first ventilation hole 19 in the airflow flowing in front of the second surface 17 of the baffle 10 is small. Since most of the airflow flowing in front of the second surface 17 of the baffle 10 flows towards region C, the noise generated in front of the car compartment 8 due to the airflow is sometimes not sufficiently suppressed.

[0059] On the other hand, such as Figure 5C As shown, when the first panel 20 is set as the guide member 11, since the first panel 20 protrudes downwards from the curved portion 18 of the baffle 10, the airflow from below the car 6 is guided to region D between the first panel 20 and the second surface 17. In region D, the first panel 20 blocks the airflow rising along the second surface 17 from flowing forward to region C. Region D becomes a space located on the air inlet side, i.e., the front side, of the first ventilation hole 19, open downwards and closed above. As a result of the airflow from below into region D, the pressure in region D becomes higher. At this time, since the pressure difference before and after the first ventilation hole 19 becomes larger, it is easy to generate airflow from region D through the first ventilation hole 19 to the rear. As a result, the amount of airflow flowing into region C becomes less, and the air velocity in region C is suppressed. Therefore, noise generated at the front of the car chamber 8 due to airflow is suppressed.

[0060] As described above, the elevator 1 of Embodiment 1 includes a car 6 that travels vertically in a lifting channel 2. The car 6 includes a car compartment 8, a baffle 10, and a guide member 11. An entrance / exit 12 is provided at the front of the car compartment 8. The baffle 10 is provided below the front end of the car compartment 8. The baffle 10 has a first surface 16 and a second surface 17 located below the first surface 16. The first surface 16 faces forward in the vertical direction. The second surface 17 is inclined rearward at an obtuse angle to the first surface 16. A first ventilation hole 19 is provided on the second surface 17. The guide member 11 is provided below the car compartment 8. When the car 6 travels downward, the guide member 11 increases the pressure difference before and after the first ventilation hole 19 by blocking part of the upward-flowing air. By increasing the pressure difference before and after the first ventilation hole 19, the guide member 11 guides the air so that more upward-flowing air flows into the first ventilation hole 19. In embodiment 1, the guide member 11 has a structure that prevents wind from rising to a position above the first vent 19 on the front side of the second surface 17, thereby increasing the pressure on the front side of the first vent 19.

[0061] As an example, the guide member 11 has a first panel 20. The first panel 20 is a plate-shaped member disposed facing forward in the vertical direction. The first panel 20 is connected to the first surface 16 in front of the baffle 10. The lower end of the first panel 20 is disposed below the first surface 16 and above the lower end of the second surface 17.

[0062] According to this structure, the guide member 11 with the first panel 20 guides the airflow that has not yet passed through the first ventilation hole 19 as the car 6 moves downward, thereby creating a pressure difference before and after the first ventilation hole 19. As a result, the amount of airflow flowing from below the car chamber 8 into the area C between the car chamber 8 and the inner wall 3 of the elevator shaft 2 is reduced, thus suppressing noise generated at the front of the car chamber 8 due to airflow. Therefore, the user inside the car chamber 8 is less likely to experience uncomfortable noise. This further improves the comfort inside the car chamber 8.

[0063] In the various embodiments described below, the differences from examples disclosed in other embodiments are described in particular detail. Any features of examples disclosed in other embodiments that are not described in the various embodiments below may also be used.

[0064] Implementation Method 2

[0065] Figure 6 This is a perspective view of elevator 1 in implementation method 2.

[0066] The elevator car 6 of elevator 1 has a guide member 11. The guide member 11 has a first panel 20. The lower end of the first panel 20 is folded back.

[0067] Figure 7 This is a cross-sectional view of the elevator car 6 of the elevator 1 in embodiment 2.

[0068] Figure 7 The figure shows a cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0069] In this example, the lower end of the first panel 20 is formed into a hairpin-shaped bend with a bending angle of approximately 180°. Alternatively, the bending angle of the lower end of the first panel 20 may be less than 180°.

[0070] Next, use Figure 8 An example illustrating noise reduction based on guide member 11.

[0071] Figure 8 This is a cross-sectional view of the car 6 in embodiment 2.

[0072] Figure 8 The figure shows a cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0073] also, Figure 8 An enlarged area showing the lower end of the first panel 20 is shown. To the left of the enlarged area, the first panel 20 without its lower end folding backward is shown. On the other hand, to the right of the enlarged area, the first panel 20 of Embodiment 2 with its lower end folded backward is shown.

[0074] Without the lower end of the first panel 20 folding backward, the radius of curvature of the lower end of the first panel 20 is equal to the thickness of the first panel 20. If the lower end of the first panel 20 has a small radius of curvature and an edge-like shape, the airflow colliding with the lower end of the first panel 20 is easily separated in front of the first panel 20. When the airflow separates, the effective cross-sectional area of ​​the air passage between the car chamber 8 and the inner wall 3 of the elevator shaft 2 becomes smaller, and therefore, the flow velocity in region C between the car chamber 8 and the inner wall 3 of the elevator shaft 2 increases. At this time, the noise suppression effect generated in front of the car chamber 8 may be weakened due to the airflow.

[0075] On the other hand, by folding the lower end of the first panel 20 backward, the radius of curvature of the lower end of the first panel 20 becomes greater than the thickness of the first panel 20. This suppresses the airflow that collides with the lower end of the first panel 20 and prevents it from being separated from the front of the first panel 20. Consequently, by suppressing the airflow velocity in region C, noise generated in front of the car compartment 8 due to airflow is suppressed.

[0076] In addition, since there are no sharp edges at the lower end of the first panel 20 due to the folding mechanism, it is easy to perform installation, maintenance, and repair work.

[0077] Implementation Method 3

[0078] Figure 9 This is a cross-sectional view of the elevator car 6 of the elevator 1 in embodiment 3.

[0079] Figure 9 The figure shows a cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0080] The elevator car 6 of elevator 1 includes a guide member 11. In this example, the guide member 11 does not have a first panel 20. The guide member 11 has a gas-permeable member 21. The gas-permeable member 21 is a member that contains internal gaps for gas to pass through. The gas-permeable member 21 is, for example, a brush or a porous material with continuous gaps. The gas-permeable member 21 is disposed on the second surface 17 of the baffle 10. The gas-permeable member 21 is installed in a manner that protrudes forward from the second surface 17. The gas-permeable member 21 is positioned above the first vent 19. In this example, the gas-permeable member 21 is disposed adjacent to the upper edge of the first vent 19.

[0081] If the gas permeable member 21 is provided as the guide member 11, the gas permeable member 21 protrudes forward from the second surface 17, thus guiding the airflow from below the car 6 towards the region E between the gas permeable member 21 and the second surface 17. The guide member 11 is the same as the first panel 20 described in Embodiment 1, having a structure that obstructs the airflow from rising to a position higher than the first vent 19 on the front side of the second surface 17. As a result, the pressure in region E increases. At this time, since the pressure difference before and after the first vent 19 increases, airflow is easily generated from region E through the first vent 19 to the rear. As a result, the amount of airflow flowing into region C decreases, and the air velocity in region C is suppressed. Therefore, noise generated in front of the car chamber 8 due to airflow is suppressed. In addition, part of the airflow flowing into region C passes through the interior of the gas permeable member 21. Since the airflow passing through the interior of the gas permeable member 21 is rectified, noise generated in front of the car chamber 8 due to airflow is suppressed more effectively.

[0082] Implementation Method 4

[0083] Figure 10 This is a perspective view of elevator 1 in implementation method 4.

[0084] The elevator car 6 of elevator 1 includes a guide member 11. The guide member 11 has a second panel 22. The second panel 22 is a plate-like member that covers at least a portion of the lower surface of the car chamber 8 from below. The second panel 22 has a trapezoidal shape with its upper surface open when viewed from the front-rear direction. In this example, the bottom surface of the second panel 22 is horizontally arranged. The left and right sides of the second panel 22 are inclined upward at an obtuse angle to the bottom surface. The front end of the bottom surface of the second panel 22 is connected to the second surface 17 of the baffle 10 at a position lower than the first ventilation hole 19. In this example, the front end of the bottom surface of the second panel 22 is connected to the lower end of the second surface 17. The second panel 22 has guide vanes 23. The guide vanes 23 are plate-like portions arranged with their surfaces facing forward in a vertical direction. The guide vanes 23 protrude downward from the front end of the bottom surface of the second panel 22.

[0085] Next, use Figure 11 An example illustrating noise reduction based on guide member 11.

[0086] Figure 11 This is a cross-sectional view of the elevator car 6 of the elevator 1 according to embodiment 4.

[0087] Figure 11 The figure shows a cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0088] If the second panel 22 is provided as the guide member 11, the airflow from below the car 6 is guided to the side of the car 8 because the second panel 22 covers the lower surface of the car chamber 8 from below. This reduces the amount of airflow flowing into region F between the second panel 22 and the lower surface of the car chamber 8. Furthermore, region F opens into the lifting channel 2 with an area much larger than the first ventilation hole 19. Therefore, without the second panel 22, the airflow from below would collide with the lower surface of the car chamber 8, causing a pressure increase. However, by providing the second panel 22, even when the car 6 descends, the pressure in region F behind the second panel 22 hardly increases. Additionally, although region F opens into the lifting channel 2 from the rear, it is not an opening facing downwards, so there is no situation where airflow from below flows into the opening, causing a pressure increase in region F. On the other hand, the front surface of the downward-sloping second panel 22 experiences increased pressure due to airflow from below. As a result, the pressure difference before and after the first ventilation hole 19 increases, making it easier for airflow to flow from the front through the first ventilation hole 19 into region F. Consequently, the amount of airflow flowing into region C decreases, thus suppressing the air velocity in region C. Therefore, noise generated at the front of the car chamber 8 due to airflow is suppressed. Furthermore, the airflow through the first ventilation hole 19 can exit from the rear of region F and flow upwards from the rear of the car chamber 8.

[0089] As described above, the guide member 11 of the elevator 1 in embodiment 4 has a second panel 22. The second panel 22 is a plate-shaped member that covers the lower surface of the car chamber 8 from below. The front end of the bottom surface of the second panel 22 is connected to the second surface 17 at a position below the first ventilation hole 19, behind the baffle 10.

[0090] According to the above structure, the guide member 11 with the second panel 22 guides the airflow that does not pass through the first ventilation hole 19 when the car 6 moves downwards to the side of the upper car compartment 8, thereby increasing the pressure difference before and after the first ventilation hole 19. As a result, the amount of airflow flowing from below the car compartment 8 into the area C between the car compartment 8 and the inner wall 3 of the elevator shaft 2 is reduced, thus suppressing the noise generated in front of the car compartment 8 due to airflow. Therefore, the user in the car compartment 8 is less likely to feel uncomfortable noise. This further improves the comfort inside the car compartment 8. The guide member 11 in embodiment 4 increases the pressure difference before and after the first ventilation hole 19 by blocking part of the upward-flowing air, which is the same as in embodiment 1. The second panel 22 constituting the guide member 11 in embodiment 4 has a structure that prevents the airflow from rising to a position lower than the first ventilation hole 19 on the rear side of the second surface 17, preventing the pressure on the rear side of the first ventilation hole 19 from rising.

[0091] Alternatively, the second panel 22 can also be made of a flat plate, but as shown in the figure, it can have a shape that does not curve upwards at the front and curves upwards at both ends of the sides in a manner that is more pronounced than at the center. This shape causes the airflow from below to flow laterally instead of through the front of the car chamber 8, thus reducing the airflow into the inflow area C, and is therefore preferred.

[0092] Additionally, the second panel 22 has plate-shaped guide vanes 23 below the front end of its bottom surface. The guide vanes 23 are arranged facing forward in a vertical direction.

[0093] With this structure, the guide vanes 23 suppress the inflow of airflow into region C from below, which collides with the bottom surface of the second panel 22. This more effectively suppresses noise generated at the front of the car compartment 8 due to airflow.

[0094] Additionally, in the second panel 22, the rear of the bottom surface can also be curved upwards. Alternatively, the bottom surface of the second panel 22 can be arranged with an upward tilt towards the rear. As a result, airflow is more easily guided to the rear of the car 6, thus increasing the pressure difference between the front and rear of the first ventilation hole 19.

[0095] Alternatively, the guide member 11 may be combined with the first panel 20 and the gas permeation member 21, etc., and the second panel 22.

[0096] Implementation Method 5

[0097] Figure 12 This is a cross-sectional view of the elevator car 6 of the elevator 1 in embodiment 5.

[0098] Figure 12The figure shows a cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0099] A second ventilation hole 24 is provided on the rear part of the bottom surface of the second panel 22. The second ventilation hole 24 is a hole for air to pass through. The second ventilation hole 24 may also be composed of multiple holes. In this case, the arrangement of multiple holes is not limited. Figure 12 The configuration shown is correct. Alternatively, the second ventilation opening 24 can also be a slit or the like. A mesh or similar material can also be installed in the second ventilation opening 24.

[0100] Airflow colliding with the bottom surface of the second panel 22 from below passes through the second vent 24, thereby promoting airflow towards the rear of the car chamber 8. Consequently, the pressure in region G between the front of the second panel 22 and the lower surface of the car chamber 8 becomes lower. At this time, because the pressure difference before and after the first vent 19 becomes larger, airflow easily flows from the front through the first vent 19 into region G. As a result, the amount of airflow into region C decreases, thus suppressing the air velocity in region C. Therefore, noise generated at the front of the car chamber 8 due to airflow is suppressed.

[0101] Implementation Method 6

[0102] Figure 13 This is a perspective view of elevator 1 in implementation method 6.

[0103] The elevator car 6 of elevator 1 includes a guide member 11. The guide member 11 has a second panel 22 and a pair of side panels 25. Each side panel 25 is a plate-like member arranged vertically. One side panel 25 is positioned to the left of the second panel 22. The other side panel 25 is positioned to the right of the second panel 22. The left side panel 25 is positioned with its surface facing left. The right side panel 25 is positioned with its surface facing right. The left side panel 25 is connected to the rear of the left end of the baffle 10. The right side panel 25 is connected to the rear of the right end of the baffle 10.

[0104] Figure 14 This is a cross-sectional view of the elevator car 6 of the elevator 1 according to embodiment 6.

[0105] Figure 14 The figure shows a cross-section of a vertical plane perpendicular to the left and right directions passing through the center of the car chamber 8.

[0106] Side slits 26 are provided on each side panel 25. The side slits 26 are slits running in the front-to-back direction. The rear side of the side slits 26 is cut off, thus opening the side slits 26 to the rear. The upper end of the side slit 26 on the left side panel 25 is positioned to match the height of the left end of the second panel 22. The upper end of the side slit 26 on the right side panel 25 is positioned to match the height of the right end of the second panel 22. In this example, the upper end of the side slit 26 on the left side panel 25 is connected to the left end of the second panel 22. Similarly, the upper end of the side slit 26 on the right side panel 25 is connected to the right end of the second panel 22.

[0107] Next, use Figure 15A and Figure 15B This illustrates an example of noise reduction based on the guide member 11.

[0108] Figure 15A This is a perspective view of elevator 1 without side panels 25 in the car 6.

[0109] Figure 15B This is a perspective view of elevator 1 in implementation method 6.

[0110] like Figure 15A As shown, a portion of the airflow colliding with the bottom surface of the second panel 22 from below may flow into region C between the car chamber 8 and the inner wall 3 of the elevator shaft 2 via the sides of the second panel 22 and the outer sides of the baffle 10 in the left and right directions. If such a portion of the airflow flows in, the flow velocity in region C increases. At this time, the noise suppression effect generated in front of the car chamber 8 may be reduced due to the airflow.

[0111] On the other hand, such as Figure 15B As shown, by providing a pair of side panels 25, airflow into region C, which is located to the left or right of the side of the second panel 22 or the outer side of the baffle 10, is suppressed. Furthermore, by providing side slits 26 in the side panels 25, airflow colliding with the second panel 22 from below is guided through the side slits 26 to pass through the side of the car chamber 8. Since the side slits 26 open rearward, airflow through the side slits 26 is less likely to flow into region C in front of the car chamber 8. Because the height of the side slits 26 is set to match the height of the left and right ends of the second panel 22, airflow colliding with the second panel 22 from below is more effectively guided to the side slits 26. As a result, the pressure in the region between the second panel 22 and the lower surface of the car chamber 8 is suppressed, thus lowering the pressure in that region. Therefore, the pressure difference before and after the first vent 19 increases, further suppressing airflow into region C. Thus, noise generated in front of the car chamber 8 due to airflow is more effectively suppressed.

[0112] Alternatively, elevator 1 may only have the structure of any one of the above-described embodiments. Furthermore, elevator 1 may also combine some or all of the structures described in the above-described embodiments.
