Further, in the first embodiment, since the operations for the driving machine 16 are performed mainly on the brake device 16a and the brake device 16a is disposed at the inspection door 14 side, operating efficiency of the operations for the driving machine 16 can further be improved.
  • the driving machine 16 is disposed at the hall entrance portion 9 of the uppermost landing floor, the length of the rope 25 can be shortened as well as the layout of the rope 25 can be simplified.
  • the entrance wall 12 and the inspection door 14, which face the elevator hall are formed of the fire-proof and sound-proof material, it is possible to prevent a flame from entering into the elevator hall side if the driving machine 16 fires accidentally. Further, it is possible to suppress the transmission of noise of the driving machine 16 to the elevator hall side.
  • the driving machine 16 is disposed between the door accommodating portion 11 and the entrance wall 12, it is also possible that the driving machine 16 is disposed at any unoccupied space left, for instance, at the side of the door accommodating portion 11.
  • the inspection door 14 is provided at the front surface of the entrance wall 12, but the inspection door 14 may be provided, for instance, at a side surface of the entrance wall 12 (i.e. a surface facing the hall entrance post 13 in Fig. 2).
  • Fig. 5 is a side view showing essential portions of an elevator apparatus according to a second embodiment of the present invention
  • Fig. 6 is a front view showing the hall entrance portion in Fig. 5 as viewed from the elevator hall side
