Claims

[Scope of utility model registration request]

A frame whose entire surface is watertight except for the opening, and whose outer surface is immersed in seawater when the ship dives into the deep sea; oil that fills and is enclosed within the frame and immerses electrical components placed within the frame; , a cylinder provided in the opening of the frame; provided on the inner periphery of the cylinder watertightly and slidably so as to make the pressure of the oil sealed in the frame the same as the pressure of seawater when the ship dives; A pressure equalization device for electrical equipment for deep sea use, comprising a water piston and a foreign matter removing member attached to the side of the piston that is immersed in seawater to remove foreign matter adhering to the inner periphery of the cylinder when the piston slides.
