Abstract

A ventilation device for a switchgear of an embodiment includes a pair of support members and a louver. The support member pair is aligned with spacing and is joined 5 to a housing. The louver is located between the support member pair, to open and close an opening in the housing. One of the support member pair and both ends of the louver in an aligning direction of the support members is provided with protrusions that protrude in the aligning direction. 10 The other of the support member pair and both the ends is provided with holes into which the protrusions are fitted, and tubular faces facing the holes. The support member pair supports the louver while the protrusions and the tubular faces are engaged with each other.
