A propelling apparatus for a ship according to the present invention comprises: an introducing tube coupled and fixed to a hull and discharging water introduced into a front end to a rear end when a ship sails; a driving shaft mounted so that one side thereof passes through the introducing tube in a widthwise direction and rotated by rotating force transmitted from a driving device; a screw mounted at a rear end side of inner spaces of the introducing tube in a rotatable structure and disposed so that a rotation axis is parallel to a longitudinal direction of the introducing tube; and a driven axis mounted to transmit the rotating force of the driving shaft to the screw and making the screw rotate when the driving shaft rotates. The propelling apparatus for a ship according to the present invention can reduce fuel costs and operation time by reducing the resistance of water applied to the screw, increase boarding comfort by reducing noise and vibration generated in the screw, and preventing damage to the screw and marine life by preventing the screw from being directly in contact with other objects. |
