Abstract
A fishing sinker device is configured to extend based on a coupling force of magnets. The fishing sinker device includes a main member formed at least partially of a magnetic material and including a lower coupling part, a sub member formed to be engaged with the main member with the same diameter, and configured to maintain a coupling force therebetween by a permanent magnet accommodated in an upper coupling part thereof, and an adjustment member added to at least one of the main member and the sub member to adjust a function thereof. Accordingly, the sinker which allows the bait to reach the desired depth during fishing have effects of increasing the usability since the shape and function of the sinker can be easily expanded matching with the type of fishing while maintaining the desired length and weight of the sinker by a magnetic force.
