Claims

[Scope of utility model registration request]

In a closed power distribution board equipped with a ventilation opening to ventilate the interior, an adsorption member is placed inside the ventilation opening to keep it open at all times, and when the internal pressure rises abnormally, the ventilation opening is closed against the adsorption force of the adsorption member. 1. A closed power distribution board comprising: a movable plate that closes the ventilation port; and an adsorption member that is provided inside a ventilation port and attracts the movable plate that is displaced to the closed state and holds the movable plate in the closed state.
