PROBLEM TO BE SOLVED: To provide a thruster of a craft, which can reduce resistance in a tunnel opening without being provided with a power source.SOLUTION: A thruster of a craft includes: a thruster tunnel 61B that is provided in a laterally penetrating manner in a hull 1B and within which a propeller 62B is arranged; a communication part 63B that communicates the inside and outside of the thruster tunnel 61B with each other; and an introduction pipe 80 that introduces a fluid into the thruster tunnel 61B from the outside of the craft and that discharges the fluid to the outside of the hull from the communication part 63B. The introduction pipe 80 has an inlet 81 that is provided at one end and that is opened in a submerged part 1W of the hull 1B, an outlet 82 that is provided at the other end and that is opened toward the communication part 63B in such a manner as to be an inner wall of the thruster tunnel 61B, and a pressure difference generation structure that generates a pressure difference so that the inlet 81 can be subjected to relatively higher pressure than the outlet 82 during sailing.

    【課題】動力源を設けることなくトンネルの開口部における抵抗を低減することができるようにした、船舶のスラスターを提供する。【解決手段】船体1Bに横方向へ貫通して設けられ、内部にプロペラ62Bが配置されたスラスタートンネル61Bと、スラスタートンネル61Bの内外とを連通する連通部63Bと、船外からスラスタートンネル61B内に流体を導入するとともに連通部63Bから船外へ流体を排出する導入管80と、を備える。導入管80は、一端に設けられ、船体1Bの没水部1Wに開口した入口81と、他端に設けられ、スラスタートンネル61Bの内壁であって連通部63Bに向かって開口した出口82と、航行中に入口81の方が出口82よりも相対的に高圧になるように圧力差を発生させる圧力差発生構造と、を有する。【選択図】図3
