ABSTRACT:
An exit (5) formed in an elevator car (1) is closed by doors (8) of multi-construction including an inner door (6) and an outer door (7). Air is able to flow between a space between the inner door (6) and the outer door (7) and the space in the elevator car (1). The elevator car (1) can be sealed in an airtight state and can be isolated from external noise. Deformation of the decorative inner surface of the inner door (6) by pressure difference between the interior and the exterior of the elevator car (1) can be prevented.
