FIG. 14 is a front view showing a state in which a conventional buoy is applied to a buoy, and FIG. 15 is a perspective view showing a state in which a conventional buoy is applied to a buoy. Hereinafter, a conventional buoy will be described with reference to FIGS. 14 and 15. FIG.

As shown in FIGS. 14 and 15, the conventional buoy main body 101 is fixed to the center of the solid cylindrical float 102 and the lower surface 102 b of the float 102. The pole 103 includes a pole 103 and a countdown eight 104 provided at the lower end of the pole 103. In the buoy main body 101, a side submerged in water is referred to as a lower side, and a side floating above the water is referred to as an upper side.

The float 102 is a member for imparting buoyancy to the buoy main body 101, and is made of a synthetic resin such as fiber reinforced plastic (FRP) or a metal such as a rolled steel material or an aluminum alloy. It is filled with urethane foam resin and sealed. Therefore, the float 102 is entirely formed in a solid cylindrical shape.

Further, the lower surface 102 b of the float 102, that is, submerged in water The pole 103 is fixed to the center of the bottom surface on the side in a hanging manner, and the counter weight 104 is fixed to the lower end of the pole 103. The pole 103 and the counterweight 104 stably levitate the float 102, whereby the buoy body 101 is provided on the side surface of the float 102. It is possible to stably float in a state where the water surface 120 is located substantially at the center in the vertical direction of 102 c.

When the buoy main body 101 having the above configuration is used as a buoy, a variety of lamps are mounted on the upper surface 102 a of the float 102, that is, on the surface floating on the water. Provide and use. For example, as shown in FIGS. 14 and 15, a tower-shaped target body 111 is provided on the upper surface 102 a, and a lamp 1 is provided on the top of the target body 111. 11 1a is attached to form a buoy.
