  • An angle ⁇ 1 at which a portion of the main ropes 8 between the main rope connecting portion 12 and the car return sheave 9 enters a groove 9a when the car 3 is positioned at the uppermost floor is greater than an angle ⁇ 2 at which a portion of the main ropes 8 between the car return sheave 9 and the deflecting sheave 11 enters grooves 11a and 9a.
  • the main ropes 8 Since the rotating shaft of the drive sheave 6 is vertical, and the orientation of the rotating shaft of the deflecting sheave 11 is horizontal, the main ropes 8 have a shape that is pinched (twisted) between the drive sheave 6 and the deflecting sheave 11. Because of this, spacing between the main ropes 8 at an intermediate point between the drive sheave 6 and the deflecting sheave 11 is smaller than the spacing P2 between the deflecting sheave grooves 11a, 11b, and 11c. Consequently, the spacing P2 is set to the smallest dimension at which the main ropes 8 do not contact each other at the intermediate point between the drive sheave 6 and the deflecting sheave 11.

  • the driving machine 5 is disposed directly above the car 3 so as to overlap with the car 3 in a vertically projected plane, and the drive sheave 6 is disposed on the upper portion of the driving machine main body 7, maintenance work on the driving machine main body 7 can be performed easily from on top of the car 3.
  • the spacing P3 between the main ropes 8 in the main rope connecting portion 12 is determined by the magnitude of the main rope connecting portion 12, and is considerably greater than the spacing P2 between the deflecting sheave grooves 11a, 11b, and 11c. Because of this, the approach angles (the fleet angles) ⁇ 1 and ⁇ 2 of the main ropes 8 are increased if the spacing P1 between the car return sheave grooves 9a, 9b, and 9c is reduced, or clearance between the car 3 and the car return sheave 9 when the car 3 is positioned at the uppermost floor is reduced, etc. For example, if P1 were hypothetically made to equal P2, the approach angle ⁇ 1 would be considerably larger than the state in Figure 3 . If P1 were hypothetically made to equal P3, the approach angle ⁇ 2 would be considerably larger than the state in Figure 4 .
