Description

  The present invention relates to an elevator cab.

In recent years, with the space saving of the hoistway, the assembly space of the elevator cab has been remarkably limited. In addition, in order to enhance cost competitiveness, it has been necessary to simplify the product structure and save labor in installing the cab. In addition, due to the shortening of the installation period, it is necessary to save labor in the installation time of the entire elevator.
Conventional elevator cabs generally have a structure using fastening members made of bolts, nuts, and the like (see, for example, Patent Document 1). There is also an elevator cab which is provided between the enclosure plates constituting the cab side walls and is fitted with a connecting material connected to the edges of both enclosure plates (see, for example, Patent Document 2).
