PURPOSE:To make vibro-isolability yet better as well as to aim at the secureness of a wide gear storage space by inserting a first rod into a hollow steering shaft being pivotally supported on a mounting bracket, and setting a second rod being connected via a coupling device to a side where it separates from a drive shaft. CONSTITUTION:A propulsive casing 16 is steerably supported on a hollow steering shaft 15 being pivotally supported on a mounting bracket of the hull, and a ship propeller is constituted of a hear storage space 21 being supported vertically in an inner part of the casing 16 and a propeller shaft 20 provided with a propeller 18 at the rear end. First rods 31A, 31B of a forward-backward selecting shift rod are inserted into the hollow steering shaft 15, and set to a side where they separate from the drive shaft 19 to each axis of these rods 31A, 31B via a coupling device 35 for a U-shaped engaging arm 36 or the like and connected to each other. The drive shaft center and the steering shaft are closely set up, and thereby the secureness of good vibro-isolating performance and a wide hear storage space is promoted. |
