  • the driving machine 9 is disposed above a corner portion of the car 4.
  • a plurality of main ropes 12 (only one is shown in the figure) are wound around the drive sheave 11.
  • Each of the main ropes 12 has: a car connecting end portion 12a connected to the car 4; and a counterweight connecting end portion 12b connected to the counterweight 5.
  • the car 4 and the counterweight 5 are suspended inside the hoistway 1 using a 1:1 roping method.
  • a first direction-changing deflection sheave 13 for directing the main ropes 12 from the driving machine 9 to the car 4, and a second direction-changing deflection sheave 14 for directing the main ropes 12 from the driving machine 9 to the counterweight 5 are supported by the supporting platform 8.
  • the first and second direction-changing deflection sheaves 13 and 14 are disposed such that rotating shafts thereof extend horizontally.

  • the car frame 21 has: a pair of vertical stanchions 21a extending vertically parallel to each other; a lower beam 23 secured between lower end portions of the vertical stanchions 21a; and an upper beam 24 secured between upper end portions of the vertical stanchions 21a.
  • the cabin 22 has: a car floor (not shown); cabin walls 25; a car door 26; and a ceiling portion 27.
  • the ceiling portion 27 has a predetermined vertical dimension (a thickness dimension) H, equipment such as lighting equipment (not shown), etc., being housed inside the ceiling portion 27.
  • the upper beam 24 is disposed such that a lower extremity portion thereof is positioned lower than an upper surface 27a of the ceiling portion 27. In this embodiment, the upper beam 24 is housed entirely within a range of the vertical dimension H of the ceiling portion 27.
  • the car connecting end portion 12a of each of the main ropes 12 is connected to the upper beam 24 by a rope end connecting apparatus 31.
  • the counterweight connecting end portion 12b of each of the main ropes 12 is connected to an upper beam 5a of the counterweight 5 by means of a rope shackle 15 and a buffering member 16.
  • FIG. 2 is a cross section taken along line II - II in Figure 1, delineation of the equipment accommodated inside the ceiling portion 27 being omitted.
