。Embodiments Hereinafter, embodiments of the present invention will be explained with reference to the drawings. In FIG. 1, 1 is a pantograph that serves as a current collector, and is generally supported by an insulator. 2
is a car body, and the pantograph 1 is installed on the roof. Reference numeral 3 denotes a pantograph cover (hereinafter simply referred to as a pantograph cover) which is provided around the pantograph 1 and corresponds to a noise reduction means surrounding the pantograph 1. The pantograph covers 3 are installed on both sides of the pantograph 1 in the vehicle width direction. Next, the structure of the pantyhose cover 3 will be explained in detail. 1 and 2 show a state in which the pantyhose cover 3 is unfolded, and FIGS. 3 and 4 show a state in which the pantyhose cover 3 is retracted. First, the unfolded state of the panty cover 3 will be explained. The panty cover 3 is entirely formed into a plate shape, and is supported by support columns 4 on both sides. The support column 4 is rotatably attached via a bearing 7 near the boundary between the roof surface 5 of the vehicle body 2 and the side surface 6. Further, a bearing 8 is provided near the middle of the support column 4, while a bearing 8' is provided on the roof surface 5,
It is connected to the roof surface 5 via a rotation drive device 9. A drive device 10 for moving the pantyhose cover 3 in and out is installed inside the vehicle body 2. Next, the state in which the panty cover 3 is stored will be explained. The pantyhose cover 3 is stored inside the vehicle body 2 by a drive device 10. Further, the support column 4 is also stored in the roof surface 5 by the drive device 9. 11
is a cover for storing the pantyhose cover 3, and is installed near the boundary between the roof surface 5 of the vehicle body 2 and the side surface 6 by means of a shaft 12. This cover 11 is automatically restored by a spring or the like. In the unfolding operation of the pantyhose cover 3, the drive device 9 first unfolds the support column 4, and then the drive device 10 causes the pantyhose cover 3 to protrude from inside the vehicle body 2. At this time, the cover 11 is pushed by the panty cover 3.
unfolds. The pantyhose cover 3 is pushed out along the groove of the support column 4. In the storage operation of the pantyhose cover 3, the pantyhose cover 3 is first lowered by the drive device 10 along the groove of the support column 4, and is stored inside the vehicle body 2. At this time, cover 1
1 automatically becomes the state shown in FIGS. 3 and 4. Next, the support column 4 is retracted by the drive device 9, and the retracting operation is completed. According to such a configuration, the panty cover 3 can be attached when necessary.
It is possible to insulate the noise of the current collector, that is, the sliding between the sliding plate of the pantograph 1 and the overhead wire, or the wind noise of the pantograph 1 itself, thereby suppressing the propagation to the sides of the vehicle body 2. On the other hand, since the panther cover 3 is rotatable, it can be retracted when the noise from the current collector is smaller than other vehicle noises. Therefore, in the stored state, the pantyhose cover 3 is stored inside the vehicle body 2, so that deterioration in the appearance of the vehicle body 2 can be prevented.
