To provide a new composition for deviating a direction change member.SOLUTION: A water jet propulsion vessel includes: a hull, a jet stream generator, a direction change member, a steering device, and a direction change mechanism. A direction change member is provided to be capable of revolving against a hull with a first revolving axis along a first direction as center along a first direction to the hull as well as being capable of revolving with a second revolving axis along a second direction orthogonal to the first direction as the center. The direction change mechanism includes a first actuator for displacing a first portion in the direction change member to a third direction orthogonal to both the first direction and the second direction, and a second actuator for changing the direction of the second portion in the direction change member to the third direction. The first revolving axis is positioned in between the first portion and the second portion in a first direction vision and at the same time, the first portion and the second portion are both positioned in one direction side in the first direction to the second revolving axis in a second direction vision.SELECTED DRAWING: Figure 7

    【課題】方向変更部材を変位させるための新たな構成を提供する。【解決手段】水ジェット推進艇は、船体と、噴流発生装置と、方向変更部材と、操舵装置と、変位機構とを備える。方向変更部材は、船体に対して、第1の方向に沿った第1の回動軸を中心に回動可能であり、かつ、第1の方向に直交する第2の方向に沿った第2の回動軸を中心に回動可能に設けられる。変位機構は、方向変更部材における第1の部分を、第1の方向と第2の方向との両方に直交する第3の方向に変位させる第1のアクチュエータと、方向変更部材における第2の部分を、第3の方向に変位させる第2のアクチュエータとを有する。第1の方向視で、第1の部分と第2の部分との間に第1の回動軸が位置し、かつ、第2の方向視で、第1の部分と第2の部分とは、いずれも、第2の回動軸に対して、第1の方向の一方側に位置している。【選択図】図7
