ーカの防水装置。 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 has a striking chamber that is made of air, and a means for pressurizing air into the striking chamber, a valve chamber that is formed in the middle of an air passage that communicates with the chamber near the striking chamber; a valve member that slides to open and close the air passage; and a biasing means that biases the valve member in a direction in which the air passage is opened; 1. A waterproof device for an underwater breaker, characterized in that a change in pressure within a striking chamber acts on the valve member so that the valve member operates in a direction to close an air passage.
