In addition to being constructed by joining the sonar transducer, the outer skin of the head that houses the sonar transducer is constructed from a rubber-like elastic body in which a fiber reinforcing material is embedded, so that the following excellent effects are achieved.
（ａ）、ソーナー送受波器を騒音源としての船底から必
要とするだけ分離しても前方からの投影面積の増大を招
くことがない。(a) Even if the sonar transducer is separated from the bottom of the ship as a noise source by the necessary amount, the projected area from the front will not increase.
（ｂ）、ソーナー送受波器を円形断面の保護装置の中心
に据えられるため、ソーナー送受波器の保８！装置膜面
に対する偏りが小さくできる。(b) Since the sonar transducer is placed in the center of the protection device with a circular cross section, the sonar transducer can be protected by 8! The bias against the device membrane surface can be reduced.
（Ｃ）、ゴム膜製保護装置の流れに対する騒音防止効果
は従来の半周から全周となるために増加できる。(C) The noise prevention effect of the rubber membrane protection device against the flow can be increased because it is now a full circumference instead of the conventional half circumference.
（ｄ）、船底との柱状連結材は断面積が小さいため防振
支持が容易となり、船内雑音の伝達を減らすことができ
