TRAVELING NOISE REDUCING STRUCTURE OF RAILROAD VEHICLE HEAD PART

PROBLEM TO BE SOLVED: To reduce traveling noise of a railroad vehicle having a gangway opening and a gangway door for blocking the gangway opening on an end panel of a head vehicle.SOLUTION: A railway vehicle end panel 10 is provided with a gangway opening 12 and a gangway door 14 for blocking the gangway opening 12, and when the gangway door 14 is closed, a space CA is formed which is opened between an edge portion 12a of the gangway opening 12 and an edge portion 14a of the gangway door 14 and essential for opening and closing operations of the gangway door 14. Due to a horizontal cross-sectional area of the space CA being reduced by a blocking member 22 provided along the edge portion 12a on an outer side of the gangway opening 12 in the vehicle width direction, traveling wind is inhibited from entering the space CA and circulating inside the space CA, and thus, cavity noise is reduced. Because the blocking member 22 is provided within an area of the space CA where it does not inhibit the opening and closing operations of the gangway door 14, the opening and closing function of the gangway door 14 is secured.
