While in Embodiments 1 through 4 the car wall 27 is provided with planar inclined surfaces 27a through 27d, it is also possible, as shown, for example, in Fig. 7, to provide the car wall 27 with a curved surface 27f opposed to an installation space 44.
  • the plan configuration of the car may also be a polygon with nine or more corners. In other words, it is only necessary for the car wall to be a tubular polyhedron with five or more faces.
  • main control panel 31 and the sub control panel 32 constitute the hoistway devices to be installed, it is also possible to install other hoistway devices in the installation space.
  • hoistway devices include such as a transformer, a battery (battery charger), and a remote control apparatus (monitoring panel).
  • the remote control apparatus consists of a monitoring panel for outputting a remote control signal to a remotely situated control room. Since in many cases the remote control apparatus is optionally installed, it has been rather difficult to secure the installation space for it. According to the present invention, however, the installation space extends substantially over the entire ascending/descending distance for the car, the remote control apparatus can be easily installed.
