As shown in FIG. 3, since the doors 11 are opened so that the door panels 11a are overlapped with each other, the space occupied by the elevator hoistway can be reduced, and the doors 11 are completely opened. You can easily go in and out.

  The elevating device 12 includes an upright guide body 121, a support frame 122, a drive mechanism 123, and a speed reducer 124.

  The upright guide body 121 of this embodiment is a conduit having a hollow inside, but is not limited to this and may be in other forms. The conduit 121 is supported by a support frame 122 and stands vertically behind the car 10.

  The drive mechanism 123 has a jagged 123a which is a long inclined tooth fixed to the outside of the conduit 121, and a motor 123b is fixed to the top surface of the car 10. A drive shaft (not shown) of the motor 123b is connected to the speed reducer 124. The speed reducer 124 is connected to the output shaft 124a. The output shaft 124a is connected to a gear 123c that meshes with the jagged 123a. The gear 123c indirectly receives the power of the motor 123b and can raise or lower the car 10. Since the motor 123b, the speed reducer 124, and the gear 123c are disposed on the top surface of the car 10, the space occupied by the building can be reduced.

  The weight device 14 includes a support portion 14a, a pulley 14b, a wire rope 14c, and a plurality of weights 14d. The support portion 14a is fixed to the upper end portion of the conduit 121 and is used for attaching the pulley 14b. The wire rope 14c is wound around the pulley 14b, one end is engaged with the top surface of the car 10, and the other end is connected to the weight 14d. The weight 14d is movably housed in the conduit 121 and moves in a direction opposite to the moving direction of the car 10 (that is, when the weight 14d is raised, the car 10 is lowered, and when the weight 14d is lowered, the car 10 is moved.
