Specifically, the upper portion of the propeller housing 332' is rotatably coupled to the lower end side lower portion of the stern body 310' via the shaft 322'-1, and the lower portion of the propeller housing 332' is rotatably passed through the shaft 322'-1. Connected to the end of the advancement guide 302' extending rearward from the lower portion of the stern body 310'.

Therefore, as the propeller casing 332' rotates, the propeller casing 332' can be integrally rotated with the left and right rudder 340' toward the left or right direction, whereby the submersible propeller can be converted in the right and left direction.

The up-and-down rudder 330' is located rearward of the propulsion propeller 320', and is a pair of horizontal rotation shafts 313' provided to the end of the extension frame 332' connected to the stern portion 300', and is rotatable up and down. part.

As shown in Fig. 17, the vertical rudder 330' is rotatable in the vertical direction with respect to the horizontal rotation shaft 313'.

On the other hand, the left and right rotation of the propeller casing 332' and the up and down rotation of the up and down rudder 330' can be realized by the manipulating portion 500' built in the ship's head portion 100', specifically, the propeller casing 332' and the up and down rudder 330' pass respectively. The pull & push cables c1, c2 are connected so that rotation can be achieved by the action of the cables c1, c2.

For example, the first cable c1 is configured such that the propeller housing 332' rotates in the left-right direction, and the second cable c2 is configured to rotate the vertical rudder 330' in the vertical direction.

Referring to Fig. 10, the first cable c1 for rotating the propeller casing 332' in the left-right direction is configured to be coupled to one side of the second bracket 540' and to the shaft provided at the upper portion of the propeller casing 332'. Thereby, the end of a cam (not shown) built in the stern body 310' is connected.

The second cable c2 for rotating the up-and-down rudder 330' in the up-down direction is configured to connect one side of the first bracket 530' and the end of the cam 330c' coupled to a part of the up-and-down rudder 330'.

Therefore, when the upper portion of the joystick 520 is operated to the left side, the first cable c1 is tightened, and the propeller housing 332' is rotated to the left rear side, and the submersible propeller is advanced in the left direction.

Further, when the upper portion of the joystick 520 is operated to the right side, the first cable c1 is pushed and pulled, and the propeller housing 332' is rotated to the rear right side, and the submersible propeller is advanced in the right direction.

Further, when the upper portion of the joystick 520 is operated toward the rear side, the second cable c2 is tightened, and the vertical rudder 330' is rotated to face upward, and the submersible propeller is pushed downward.

Further, when the upper portion of the joystick 520 is operated toward the front side, the second cable c2 is pushed and pulled, and the vertical rudder 330' is rotated to face downward, and the submersible pusher is advanced upward.

On the other hand, the joystick 520 may include a 360° tilting operation, which may be based on the direction in which the upper portion of the joystick 520 is operated and the degree of operation (the cable c1, c2 is pulled or pushed), and the propeller housing 332' and up and down The direction of the rudder 330' operates in a variety of states.

The present invention has been described in detail with reference to the accompanying drawings, in which FIG. Therefore, the scope of the invention should be construed as including the embodiment of the modifications in the scope of the claims.
