Summary: | A device for reducing frictional resistance includes: a chamber which is provided to a draft part of a hull and in which blowing holes blowing out air into the water of the outside of the hull from different positions to each other in a height direction of the hull are formed; a supply pipe supplying the air to an internal space of the chamber; and a distributor provided to each of the blowing holes, and guiding a part of the air, which was supplied inside the chamber from the supply pipe, to each of the blowing holes. The plurality of distributors has a flow-amount adjuster adjusting a flow amount of the air guided to the blowing hole corresponding to each of the distributors so that the flow amount of the air blown out from the plurality of blowing holes is equalized in each of the blowing holes. |
