Abstract
Provided is an air flow regulator for a railway vehicle, which is configured so that the rattling of bars can be prevented without using welding, an affixation member, etc. An intake grill is provided at an intake opening for sucking air from an interior of a railway vehicle. The intake grill comprises a frame, bars (40), and a deformation means. The frame defines an outer edge of the intake opening. The bars (40) are plate-shaped members spanned between portions of the frame to connect the portions to each other. The deformation means elastically deforms the bars (40) to generate reaction force therein.
