ABSTRACT:
A buffer device for an elevator employs, as a buffer member, a foamed plastic material such as polyurethane foam which undergoes very little permanent deformation upon receipt of an impact. The foamed plastic material is accommodated in a box made of a thin non-combustible material, and a heat-insulating material is disposed between the box and the buffer member in the box.
