RAILROAD VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/157964
Kind Code:
A1
Abstract:
An exhaust port (61) is provided in each of the pair of gable end structures (104) of a railroad vehicle (100). A cover (4) is disposed so as to open only downward and cover the periphery of the exhaust port (61). A closing plate (3) is pivotably supported at a position below the exhaust port (61), pivots toward the outside of the vehicle with respect to the gable end structure (104) under its own weight, and is locked to the cover (4). In this case, the closing plate (3) is bridged between the gable end structure (104) and the cover (4), closes part of a flow path (9) formed by the cover (4), and opens the exhaust port (61). When the railroad vehicle (100) travels, the closing plate (3) of the gable end structure (104) located in the direction of travel of the vehicle pivots toward the gable end structure (104) side due to the wind pressure of outside air entering from below the cover (4), and closes the exhaust port (61).
