摘要

PROBLEM TO BE SOLVED: To solve the problems of not only difficulty of the production but also not achieving the desired flying distance or shortening the flying distance when the sinker is actually used although many proposals for attaching wings to the conventional sinker having a cannonball shape are provided because the casting requires the distance to be cast. ;SOLUTION: This sinker is formed so as to have a V-shape or Y-shape in the front or back view, and so that one side in the longitudinal direction may be gradually tapered to the tip 3, and the other side in the longitudinal direction may be connected to a line, and is composed of a resin plate made of a plastic including a metal thin plate of lead or the like buried therein so that the center of gravity may be positioned at the front side.;COPYRIGHT: (C)2000,JPO
