| description | This perforated plate is disposed so that air layer is formed between plate-shaped or wall-shaped blocking components and the perforated plate, and has a number of through holes. A through hole has the maximum diameter portion formed on one surface of the perforated plate and the minimum diameter portion formed on the other surface of the perforated plate. The through hole expands outward from a straight line connecting the maximum diameter portion and minimum diameter portion in cross-sectional view along the thickness direction of the perforated plate. |
