LIGHT-SHIELDING GRILLE AND STERILIZATION UNIT

WIPO Patent Application WO/2023/145234

A1

Provided is a light-shielding grille having a reliable light-shielding grille structure that allows air in and out but does not leak light, and composed of a small number of components.　The light-shielding grille (21) according to an embodiment comprises: a plurality of louvers (22) each having a substantially V-shaped transverse cross section; and a frame body (23) that accommodates the plurality of louvers (22) overlapping each other in a state in which the orientations of the apexes of the V-shapes are aligned. The louvers (22) each have a projection (232d) at the longitudinal end, and the frame body (23) has an engagement portion (234) that engages with the projection (232d) of the louver (22). The engagement portion (234) holds the louvers (22) in the frame body so that the shortest distance between the apex of the V shape of a louver (22) and an imaginary straight line connecting the ends of the V shape is greater than the distance between the apex of the louver (22) and the apex of the other louver adjacent to the louver (22).
