ELECTRICAL STORAGE DEVICE AND CONSTRUCTION MACHINE PROVIDED WITH SAME

摘要

An electrical storage device is provided with capacitor cells as a plurality of electrical storage cells, and a housing (122) in which the capacitor cells are accommodated. The housing (122) has a verification window (40) from which internally disposed LEDs (137,138) serving as status display means can be seen. The verification window (40) is provided with through holes (41) which penetrate through the housing (122), a transparent plastic plate (43) which seals the through holes (41) from the inside of the housing (122), and a seal member (42) which is interposed between the plastic plate (43) and the surroundings of the through holes (41) on the inner surface of the housing (122).
