The present invention relates to a device for preventing a fish hook from snagging on the bottom, the device comprising: an eye insertion part (100) made from a soft material having an excellent elasticity, such that a hook eye (11) to which a fishing line (20) is tied is inserted therein a line guide part (110) through which the fishing line (20) passes, and which is made from the same material as that of the eye insertion part (100), maintains, at the upper end of the eye insertion part (100), a state of being bent in an "inverted L" shape and is stretched so as to form a "straight" shape in conjunction with the eye insertion part (100) when a hookset is performed with the fishing line (20) and a snagging prevention piece (200) of which both ends (210) maintain a state, in which the both ends thereof are opened into a "V" shape over the hook point (13) of a fish hook (10) hooked into the eye insertion part (100), at both side surfaces of a front edge part (120) at which the eye insertion part (100) and the line guide part (110) come into contact with each other, and the both ends (210) are rotated toward a hook shank (12) when the line guide part (110) is stretched by a hookset and the like, and thus maximally preventing the loss of fishing tackles since the concern that the hook point is snagged on weeds or bedrocks in water is eliminated by the snagging prevention piece for effectively blocking the side above the hook point, and obtaining a great effect of luring a big fish since, when the snagging prevention piece is formed as a fake bait having the shape of a small fish, a live bait and the fake bait of the fish hook can be used together.La présente invention concerne un dispositif pour empêcher un hameçon de saccrocher au fond, le dispositif comprenant : une partie dinsertion dœil (100) constituée dun matériau souple ayant une excellente élasticité, de sorte quun œil de crochet (11) auquel une ligne de pêche (20) est nouée soit inséré dans celle-ci une parti
