PURPOSE: To prevent air from being sucked by a pump device without working an inner wall surface of a tank case into a mirror surface by separating working oil from the air in a tank device. CONSTITUTION: In a tilt.trim device 17 of a propeller for a ship having a cylinder device 18 disposed between a propulsion unit provided obliquely to a hull provided with a propeller, a pump device to supply working oil to the cylinder device 18 for expanding and contracting the cylinder device 18 and a tank device 20 to store the working oil from the cylinder device 18 to give tilt.trim operation to the propulsion unit through expansion operation of the cylinder device 18, the tank device 20 is constituted to be disposed removably in a first chamber member 51 which enables separation of the working oil from air. |
