装置。 A chisel supported reciprocally at the front of the cylinder, a hammer disposed on the same axis as the chisel and reciprocably supported at the rear of the cylinder, and formed around the opposing portion of the hammer and chisel. A breaker that can be used underwater and has a blowing chamber made of air and a means for pressurizing air into the blowing chamber, comprising a communication hole that communicates the blowing chamber with the outside of the cylinder, a valve member that opens and closes the communication hole, and a means for pressurizing air into the blowing chamber. A biasing means for biasing the valve member in a direction in which the communication hole is closed is provided, and when water enters the striking chamber and the pressure in the chamber increases due to advancement of the hammer,
A waterproofing device for an underwater breaker, characterized in that the pressure is applied to the valve member so that the valve member operates in the direction of opening the communication hole.
