Abstract

PURPOSE:To discharge heat generated in a storing box main body to the outside without adhering dust on the surface of an electric equipment base board by permitting ventilation to the inside of the storing box main body to be carried out through a vent provided on a protecting cover and a ventilation duct provided on a ceiling cover separately from the storing room of a mounting board. CONSTITUTION:The top edge part of the front plate 3 of a storing box main body 1, whose front plane is overlapped with a fixed electric equipment base board 2, is provided with a notched part 3a, a ventilation duct 4a which is air-tightly inserted into the notched part is provided at the bottom plate of a ceiling cover 4 which covers the top opening of the storing box main body and a vent 13a is formed on a protecting cover 13 which covers the front of the electric equipment base board 2 for air-tightly communicate with the ventilation duct 4. The ventilation flow from the vent 13a and to the ventilation duct 4a is separated from the storing room A of the electric equipment base board 2, which is composed of the protecting cover 13, the front plate 3 and the ceiling cover 4. Since the electric equipment base board 2 is in the storing room A surrounded by the protection cover 13, the ceiling cover 4 and the front plane 3, dust from the outside does not invade. Heat generated in the storing box main body 1 is discharged to the outside from a releasing part 14 at the rear by the ventilation flow from the vent 13a on the protecting cover 13 to the ventilation duct 4a on the ceiling cover 4.
