Zusammenfassung:	PURPOSE: To fall a pantograph cover in the foundation limit of a vehicle at the time of non-current collecting while sufficiently alleviating the aerodynamic sound or the aerodynamic drag of the pantograph at the time of current collecting even in the vehicle in which a roof height is sufficiently lowered. CONSTITUTION: A pantograph cover 7 is supported on the roof 21 of a vehicle 1 via an insulator 5 together with a pantograph 2, while the cover is divided into a base cover 7a and an upper cover 7b at the position slightly lower than the predetermined height corresponding to the height of the foundation limit of the vehicle 1 to be used. The cover 7b is raised as the pantograph 2 is raised to the current collecting position, and the necessary height range H of the pantograph 2 at the time of current collecting is covered by both the base and the upper covers 7a, 7b, and the pantograph 2 and the cover 7b are stored in the cover 7a at the time of no-current collecting.
