  The present invention relates to a float, and more particularly to a device that adjusts the visual recognition state of light emitted to the outside.

A conventional fishing float will be described with reference to FIGS. As shown in FIG. 5, a fishing float 100 includes a body 103 that houses a light source 110 and a battery 122 and obtains buoyancy, a rod-like top 102 that is attached to the upper portion of the body 103 and takes a contact, and a body 103. The socket 104 is detachably attached to the lower part of the socket 104 and allows the battery 122 and the like to be exchanged.
The top 102 serves as a mark that conveys the movement of the fish under the float and the state of the food. In addition to being brightened by receiving light from the light source 110, the top 102 is formed of a light material that is not easily damaged and is not damaged. The top 102 is provided with color-coded scales 105 to improve the visibility in order to reliably and finely convey the situation under the water surface S such as food drop or hit.
The top 102 has a two-layer structure of an optical fiber 106 and a sheath tube 107 covering the periphery thereof.

As shown in FIG. 6, a gap is provided between the optical fiber 106 and the sheath tube 107 to create an air layer 108 so that the buoyancy as the top 102 is increased. The optical fiber 106 is formed so that light leaks out by making a fine wound 123 in a spiral shape.
The top 102 having a two-layer structure is provided with a scale 105 toward the sheath tube 107. The scale 105 is color-coded alternately into a black portion 105 b and a colored portion 105 c in the vertical direction on the peripheral surface of the sheath tube 107 constituting the top 102. In this case, the black portion 105b does not emit light, while the colored portion 105c transmits light of the light emitting diode leaking from the inner optical fiber 106 and emits light in a predetermined color. The top 102 is provided with six black portions 105b and six colored portions 105c.
