PROBLEM TO BE SOLVED: To provide a rudder plate capable of suppressing generation of vibrations of the rudder plate itself by an eddy current separated from a rear edge part of the rudder plate during navigation of a craft, without the use of a particular member.SOLUTION: A rudder plate 3 of the present invention includes a first rudder surface (starboard-side rudder plate 4) that constitutes one of front and back sides, and a second rudder surface (port-side rudder plate 5) that constitutes the other one of the front and back sides. At least one of the first and second rudder surfaces has a plurality of plate materials intermittently joined together by a connection band that is formed by making the adjacent plate materials overlap each other.SELECTED DRAWING: Figure 2
【課題】格別な部材を用いることなく、船舶の航行中に、舵板の後縁部からの剥離する渦流により、舵板自身の振動の発生を抑えることができる舵板を提供する。【解決手段】本発明の舵板3は、表裏の一方を構成する第一舵面(右舷側舵板4)と、表裏の他方を構成する第二舵面(左舷側舵板5)と、を有し、第一舵面及び第二舵面の少なくとも一方が、複数枚の板材を、隣接する板材同士を重ね合わせて形成された接続帯で間欠的に接合される、ことを特徴とする。【選択図】図2
