PROBLEM TO BE SOLVED: To enhance the airtight effect by smoothly displacing respective outside plate members, with a simple structure, by constituting an external hood of the plurality of outside plate members.SOLUTION: The external hood 3 has the plurality of outside plate members 3A supported by vehicle bodies of front and rear vehicles by using universal joints 17 and 18 and hinge brackets 19 and 20 by first and second link arms 13 and 14 so as to be juxtaposed in the peripheral direction in the outer peripheral direction between the vehicle bodies, and blocking up between the vehicle bodies of the front and rear vehicles, and the respective outside plate members 3A are displaced in response to a vehicle body bias between the vehicle bodies of the front and rear vehicles. First and second guide rail members 15 and 16 are arranged in parallel on an inside surface of the respective outside plate members 3A. One end part of the first link arm 13 is joined so as to be rotatable on the vehicle body of one vehicle out of the front and rear vehicles and the other end part is joined so as to be slidable on the first guide rail member 15, respectively. One end part of the second link arm 14 is joined so as to be rotatable on the vehicle body of the other vehicle, and the other end part is joined so as to be slidable on the second guide rail member 16, respectively. |
