Abstract

A ventilation device for a switch gear according to an embodiment of the invention is provided with a pair of support members (11) and a louver (12). The pair of support members (11) are arranged at a distance from each other and are joined to a housing (2). The louver (12) is located between the pair of support members (11) and opens and closes an opening (8c) provided in the housing (2). Either the pair of support members (11) or the opposite ends (12a, 12b) of the louver (12) in the direction (D1) in which the support members (11) are arranged are provided with protrusions (12f, 12g) protruding in the arrangement direction (D1). The pair of support members (11) or the opposite ends (12a, 12b) to which the protrusions (12f, 12g) are not provided are provided with holes (11c) in which the protrusion (12f, 12g) are inserted, and also with cylindrical surfaces (11d) facing the holes (11c). The pair of support members (11) supports the louver (12) while the protrusions (12f, 12g) and the cylindrical surfaces (11d) are engaged with each other.
