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.

1-10. (canceled)
An air flow regulator provided at a ventilation opening for at least either blowing air to an interior of a railway vehicle or sucking air from the interior of the railway vehicle, comprising:
- a frame defining an outer edge of the ventilation opening;
- and
- a bar which is a plate-shaped member elastically deformed so as to generate a reaction force therein, and spanned between portions of the frame so as to connect the portions to each other.
A method for manufacturing an air flow regulator provided at a ventilation opening for at least either blowing air to an interior of a railway vehicle or sucking air from the interior of the railway vehicle, the method comprising:
- a deformation step of elastically deforming a bar which is a plate-shaped member spanned between portions of a frame defining an outer edge of the ventilation opening so as to connect the portions to each other;
- and
- a fixation step of fixing the bar to the frame while maintaining a state of the bar elastically deformed by performing the deformation step.
