To provide a vessel lateral propulsion unit capable of reducing eddy resistance and friction generated during sailing and facilitating access during maintenance.SOLUTION: A lateral propulsion unit 1 is defined in a hull 4 of a vessel 2 and configured to include a steering propeller in a steering tunnel 3. The steering tunnel has a boundary defined by a tunnel wall extending between a first tunnel entrance 7 and a second tunnel entrance, and has a support structure 10 that includes a counter joint 27. The support structure is separably connected to a joint 9 by the counter joint. The lateral propulsion unit 1 further comprises at least two closing doors 12 formed to close the entire tunnel entrances. The support structure includes hinges 11. The closing doors 12 are rotatably fixed only to the hinges of the support structure. When the counter joint of the support structure is separated from the joint, the closing doors are separated together with the support structure from the steering tunnel, thus enabling access to the steering tunnel.SELECTED DRAWING: Figure 17

    【課題】巡航中に発生する渦抵抗および摩擦を低減し、メンテナンス時のアクセスを容易にする横方向推進装置を提供する。【解決手段】横方向推進装置1は、船2の船体4内に画定され、操縦トンネル3に操縦プロペラを含むように構成され、操縦トンネルは、第1のトンネル入口7と第2のトンネル入口との間に延びるトンネル壁によって境界が定められ、カウンタ継手27を含む支持構造体10を備え、支持構造体は、カウンタ継手で、継手9に、分離可能な態様で連結される。横方向推進装置は、閉鎖位置にあるときに、トンネル入口を全体として閉鎖するように形作られた少なくとも2つの閉鎖扉12を更に備え、支持構造体は、ヒンジ11を含み、閉鎖扉12は、支持構造体のヒンジのみに回転可能にヒンジ止めされ、支持構造体のカウンタ継手が継手から分離されたとき、閉鎖扉が、支持構造体と共に、操縦トンネルから分離して、操縦トンネルへのアクセスを可能にする。【選択図】図17
