| 摘要 |
The present invention relates to a fishing sinker comprising a center of gravity part to match floating buoyancy and gravity equilibrium in water; a first holding part on the upper side of the center of gravity part to be tied on the lower part of a fishing line; and a second holding part on the lower part of the center of gravity part to tie a fixing string of a fishing needle. The fishing sinker compresses the first holding part and the second holding part to the center of gravity part based on a caulking process, but freely rotates along with the direction of the fishing line by making a gap between the holding part and the center of gravity part, thereby easily being taken out from stones when the fishing sinker is stuck between the stones. Therefore, water pollution due to the fishing sinker can be prevented. |
