The invention provides a propulsion device of an adjacent twin screw ship having a shaft bracket, and a ship. The propulsion device of a ship comprises: a port side propeller and a starboard propeller; a steering wheel disposed on a ship width direction center; and shaft brackets disposed on front sides of the port side propeller and the starboard propeller respectively, and supporting rotatably,propeller shafts of the port side propeller and the starboard propeller respectively. Distance between a tip end of a propeller blade of the port side propeller and a tip end of a propeller blade of the starboard propeller on the ship width direction center side, is longer than 0 m and equal to or shorter than 1.0 m, and rotation directions of the port side propeller and the starboard propeller are external rotation directions, rotating from the ship width direction center side to outward, on upper parts of the port side propeller and the starboard propeller.
本发明提供一种具有轴托架的接近双轴船的推进装置、船舶。船舶的推进装置具备左舷螺旋桨及右舷螺旋桨、配置于船宽方向中心的舵、分别设置在左舷螺旋桨及右舷螺旋桨的前方并将左舷螺旋桨及右舷螺旋桨的螺旋桨轴支承为旋转自如的轴托架,船宽方向中心侧的左舷螺旋桨的螺旋桨叶片的前端与右舷螺旋桨的螺旋桨叶片的前端之间的距离设为大于0m且1.0m以下,左舷螺旋桨及右舷螺旋桨的旋转方向设为在左舷螺旋桨及右舷螺旋桨的上部从船宽方向中心侧朝向外侧旋转的外旋。
