24 is Kotkupit, 20 is Finkiel. As shown in FIG. 3, the rudder shaft 4 is made of carbon fiber reinforced plastic and has an annular cross section, and the rudder plate 3 is provided so as to enclose the rudder shaft 4. The steering plate 3 is made of fiber-reinforced plastic (hereinafter referred to as
A core material 8 made of a plastic foam material such as urethane is filled inside an outer skin 7 made of FRP (FRP), and a blade 5 is arranged on the center line of the steering plate 3.
One end of the blade is brought into contact with the rudder shaft 4, and a covering material 6 is attached so as to cover the rudder shaft 4 and sandwich the blade 5.
This covering material 6 is made of, for example, fiber-reinforced plastic made of a mixture of carbon fibers and glass fibers, and is bonded to the rudder shaft 4 and the blades 5. An adhesive 13 is filled on both sides of the joint between the rudder shaft 4 and the blade 5. The blade 5 is made of carbon fiber reinforced plastic, and its other end is positioned by interposing a spacer 51 between it and the outer skin 7.
It is fixed with FRP mesh material 9. The blade 5 and the eyeliner 9 are attached to a certain area above the rudder plate 3 as shown in FIG.

外皮７に対して固定させている。 A recess into which the show piece 12 is fitted is formed below the center of the rudder plate 3, so that the rudder axle 4
A different rudder shaft 10 is embedded. This rudder shaft 10
A spacer 14 is interposed between the steering wheel and the rudder shaft 4 above it, and a covering material 6 made of reinforcing fibers made of a mixture of carbon fiber and glass fiber is wrapped around both the rudder shafts 4 and 10. It is connected to shaft 4. This portion is further fixed to the outer skin 7 by a FRP covering material 9.
このようにして舵板３を構成すると舵軸に対す

工面では上記同様の利点が発揮される。 By configuring the rudder plate 3 in this way, the connection to the rudder shaft can be made over a wide range, so the connection is strong, and the load is not concentrated locally but is dispersed over a wide range, which improves the strength. preferable. Since the rudder shaft is made of carbon fiber-reinforced plastic, the bonding by the covering material 6 has good adhesion and strong bonding, which allows the rudder plate 3 to be made thin and reduces the resistance of the rudder plate during sailing. Can be made smaller.
The rudder shaft 4 may be constructed entirely of carbon fiber-reinforced plastic as shown in the figure, or it may be constructed by arranging a thin metal pipe in the center and wrapping carbon fiber-reinforced plastic around the outer circumference of the pipe. good. In this case, if the metal pipe is made very thin and most of the wall thickness is made of carbon fiber reinforced plastic, in other words, if the main body is made of carbon fiber reinforced plastic, the weight increase will be small, and the processing will be the same as above. The advantages of this are demonstrated.

ヤ１６を介在させている。 At the upper end of the rudder plate 3, as shown in FIG. A bearing 18 is arranged on the inner circumferential surface of the lower end of the shaft tube 17, so that the bearing material 17 is located at this portion. Reference numeral 16 is a washer made of a material with a low coefficient of friction, such as diyuracon. As shown in FIG.
The show piece 12 is attached to the hull by being fixed to the skeg 11 with a screw. The show piece 12 is provided with a shaft 19, and this shaft 19 is fitted into the lower end of the rudder shaft 4, so that the rudder shaft 4 rotates around this shaft. In order to reduce the coefficient of friction during this rotation and to prevent electrolytic corrosion from occurring on the steel showpiece 12 and shaft 19, a sleeve 22 made of high-density polyethylene is attached to the inner peripheral surface of the rudder shaft 4. A washer 16 is interposed between it and 12.
以上説明したように、この発明は舵軸の主体を

能も高めることができる。 As explained above, in this invention, the main body of the rudder shaft is made of carbon fiber-reinforced plastic, and it can be joined to the rudder plate by adhesion using FRP lining material, etc., making processing very easy. ,
Furthermore, since it is possible to bond over a wide area, there is no stress concentration, and since the rudder shaft is also lighter, the pitching moment of the sailboat is reduced, and sailing performance can be improved.
