Disclosed is a foam ejector for a ship, which is capable of generating and discharging fire extinguishing foam to a deck of the ship where a fire takes place, which constitutes a fixing basement to be installed at the deck of the ship, a fitting capable of performing left and right rotations about the fixing basement, an ejecting tube capable of performing up and down angular motions, and a rotational joint which is formed as a pipe connecting part of the type wherein a plug portion is inserted into a socket portion and two rows of pluralities of ball bearings for supporting rotations of the fitting and the ejecting tube are disposed within the rotational joint. Due to this structure, a relatively wide contacting and supporting area may be provided within the rotational joint so that the rotational joint can very firmly support an exhaust pressure of the fire extinguishing foam. Furthermore, it is possible to highly reduce the total overall weight of the foam ejector and thereby resulting in a considerable reduction in time and costs to be spent for the transportation and the installation of the foam ejector. Furthermore, a steering lever becomes easy and reasonable to be installed at the rotational joint and it easy to operate the foam ejector. |
