RAILCAR DOOR APPARATUS AND RAILCAR

摘要

A railcar door apparatus includes: a side sliding door that opens and closes an opening of a side bodyshell of a railcar; a first elastic member attached vertically to an end of the door; and a second elastic member opposed to the first so they do not touch when the door is closed. The first elastic member includes a first base portion and a first projecting wall portion projecting from the base toward the second elastic member; the second elastic member includes a second base portion and a second projecting wall portion projecting from the base toward the first elastic member; when the door is closed, a gap space is formed between the first and second elastic members, and the projecting wall portions overlap; and vertical grooves or projections are formed on the outside of at least one of the projecting wall portions, the outer surface facing the gap space.

1. A railcar door apparatus comprising:
a side sliding door configured to open and close a door opening portion of a side bodyshell of a railcar; a first elastic member attached to a door end of the side sliding door in a vertical direction; and a second elastic member opposed to the first elastic member so as not to contact the first elastic member when the side sliding door is completely closed, wherein: the first elastic member includes a first base portion and a first projecting wall portion projecting from the first base portion toward the second elastic member; the second elastic member includes a second base portion and a second projecting wall portion projecting from the second base portion toward the first elastic member; when the side sliding door is completely closed, a gap space is formed between the first elastic member and the second elastic member, and the first projecting wall portion and the second projecting wall portion are located so as to overlap each other when viewed from a normal direction of the side sliding door; a plurality of grooves or projections extending in the vertical direction are formed on an outer surface of at least one of the first projecting wall portion and the second projecting wall portion, the outer surface facing the gap space; and when the side sliding door is completely closed, the grooves or projections do not contact the first projecting wall portion or the second projecting wall portion.
