Each door is essentially composed of a door main body having a vertically extending reinforcement member for supporting the dead weight of each door and a thermal insulating panel fixedly secured to the door main body on the elevator platform side, the thermally insulating panel being filled with a thermal insulating material, and a decorative plate is adhesively secured to the front surface of the thermal insulating panel on the elevator platform side.
