At this time, since the sealing member 42 inside the joining member 41 is in close contact with the surface of the vertical plate 38A, the gap between the front panel 11A1 and the door panel 13A is closed, so that the air in the passenger compartment 11 leaks to the outside. Can be suppressed.

  Next, the structure of the lower part of the periphery of the opening 12 will be described in detail with reference to FIG.

  FIG. 9 is a cross-sectional view taken along the line CC of FIG.

  As shown in FIG. 9, the sealing device 15 </ b> C closes a gap formed between the lower part of the periphery of the opening 12 and the door 13. Specifically, the sealing device 15C is laid on the floor 11B along the opening and closing direction of the door 13, and is provided at a concave door rail 45 for guiding the door 13, and a lower end portion of the door panel 13A, and from the bottom surface of the door panel 13A to the door rail. The door shoe 46 slides on the door rail 45 while the door 13 is opened and closed, so that the door panel 13 </ b> A moves while being guided along the door rail 45.

Has been. The blower 16A is connected to the above-described atmospheric pressure sensor, and the measured value of the atmospheric pressure sensor is used for controlling the atmospheric pressure in the passenger compartment 11 by the blower 16A.

  Therefore, in the atmospheric pressure control device 16, when the door 13 is closed, the air blower 16 </ b> A adjusts the amount of air sent to and from the passenger compartment 11 according to the atmospheric pressure inside and outside the passenger compartment 11 measured by the atmospheric pressure sensor. By doing so, the atmospheric pressure in the passenger compartment 11 is controlled. In addition, in 1st Embodiment of this invention, although the atmospheric | air pressure control apparatus 16 demonstrated the structure containing the one air blower 16A, you may comprise not only in this case but a several air blower. Moreover, although the case where the blower 16A was installed on the ceiling 11C of the cab 11 was described, the present invention is not limited to this case, and the blower 16A may be installed at a position other than the ceiling 11C in the cab 11.

  As described above, the atmospheric pressure in the passenger compartment 11 is controlled by the atmospheric pressure control device 16 in a state where the gap between the peripheral portion of the opening 12 and the door panel 13A is sealed by the sealing devices 15A to 15C. Due to the rapid entry into the passenger compartment 11, noise due to a very loud wind noise is generated in the passenger compartment 11.

The fur material 50A according to the first embodiment of the present invention has a flat plate shape that is set to a length equivalent to that of the top frame 21 in the opening and closing direction of the door 13, and the protruding portion 21C of the top frame 21 and the door panel. It faces the door panel 13A at a position between 13A.

  For example, as shown in FIG. 8, the fur material 50B is disposed on the downstream side of the sealing member 42 of the sealing device 15B in the air inflow path. The fur material 50B according to the first embodiment of the present invention has a flat shape set to a length equivalent to the height of the opening 12 in the vertical direction, and is located between the horizontal plate 39 and the door panel 13A. It faces the door panel 13A.

  For example, as shown in FIG. 9, the fur material 50C is disposed downstream of the seal members 47A and 47B of the sealing device 15C in the air inflow path. The fur material 50 </ b> C according to the first embodiment of the present invention has a rectangular parallelepiped shape set to a length equivalent to the width of the opening 12 in the opening / closing direction of the door 13, and on the floor 11 </ b> B along the door rail 45. And is opposed to the bottom surface of the door panel 13A at a position between the floor portion 11B and the door panel 13A.

  4 and 8, the car 3 includes position adjusting devices 51A and 51B that are provided on the front panel 11A1 and adjust the positions of the fur materials 50A and 50B. For example, as shown in FIG. 4, the position adjusting device 51A has a length that allows the back surface of the fur material 50A to be fixed to one piece arranged in parallel to the door panel 13A and allows the shaft portion of the bolt 83A to be inserted into the other piece. The L-shaped bracket 51A includes a hole-shaped insertion hole 51a, and the L-shaped bracket 51A is attached to the horizontal portion 21B of the top frame 21 by a bolt 83A and a nut 83B.

  For example, as shown in FIG. 8, the position adjusting device 51 </ b> B has an elongated hole in which the back surface of the fur material 50 </ b> B is fixed to one piece arranged in parallel to the door panel 13 </ b> A, and the shaft portion of the bolt 84 can be inserted into the other piece. The L-shaped bracket 51 </ b> B is attached to the inner piece 40 by a bolt 84. The inner piece 40 is formed with a female screw (not shown) to which the bolt 84 is screwed. In FIG. 8, the bolt 84 is tightened at the position where the fur material 50B is pressed against the door panel 13A by the L-shaped bracket 51B.

  According to 1st Embodiment of this invention comprised in this way, since the fur materials 50A-50C as a relaxation member are arrange | positioned between the circumference part of the opening 12, and the door panel 13A, in the hoistway 2 As the car 3 travels, external air passes through the fur materials 50A to 50C when the outside air flows into the car room 11 from the gap between the periphery of the opening 12 and the door panel 13A.

  At this time, the plurality of soft fibrous protrusions of the fur materials 50A to 50C alleviate the disturbance of the air flow generated between the peripheral portion of the opening 12 and the door panel 13A, thereby facilitating air circulation. Therefore, the peak value of the wind noise caused by the air can be suppressed.
