ROLLING STOCK AND SHIELD WALL FOR COLLECTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the noise from a collector device when a high speed vehicle runs at a high speed. SOLUTION: A plurality of granules 40 are arranged in the internal space of a side wall 32 for shielding a collector device 20. The granules 40 are oscillated by a vibration of the side wall 32, as a result the wall's vibration is suppressed. Consequently, noise from individual parts can be suppressed.
