PROBLEM TO BE SOLVED: To provide an underwater moving vehicle the motion performance of which is improved and the position of which can be kept stable.SOLUTION: An underwater moving vehicle includes: a vehicle body 1 preset so that the weight thereof becomes larger than the buoyancy generated in water; a thrust part 32 generating upward thrust by driving a screw propeller 21; a drive adjustment part 50 adjusting drive of the screw propeller 21 and generating the upward thrust equivalent to the difference between the weight and the buoyant to control the water depth of the vehicle body 1 to be located at a prescribed position; and a water flow deflection part 34 deflecting the downward water flow generated by the screw propeller 21 to move the vehicle body 1 toward a horizontal direction.SELECTED DRAWING: Figure 3
【課題】ビークルの運動性能を向上させ、かつビークルの位置を安定的に保つことができる水中移動ビークルを提供する。【解決手段】重量が水中で生じる浮力よりも大きくなるように予め設定されたビークル本体1と、スクリュープロペラ21を駆動させることで上向きの推力を発生させる推力部32と、スクリュープロペラ21の駆動を調節し、重量と浮力の差分相当の上向きの推力を発生させることでビークル本体1の水深を所定の位置に制御する駆動調節部50と、スクリュープロペラ21により生じる下向きの水流を偏向させることでビークル本体1を水平方向に移動させる水流偏向部34と、を備える。【選択図】 図3
