A kind of sinker device includes: the cephalic par of a heavy bait with one of opposite cephalic par and tail end and the protrusion heavy bait and the bulge loop with a combined hole, the heavy bait and the bulge loop are made of non-lead metal material consubstantiality. The heavy bait of the utility model and the bulge loop are made of consubstantialities, so manufacture is upper relatively simple easy, and it replaces lead metal material using non-lead metal material, can reduce the pollution of the murder by poisoning to natural ecological environments such as ocean and fish.一種沉子裝置，包含：一個具有相反之一個頭端部和一個尾端部的沉餌，及一個突出該沉餌之該頭端部且具有一個結合孔的凸環，該沉餌及該凸環是由非鉛金屬材料同體製成。本新型之該沉餌及該凸環是同體製成，所以製造上較為簡單容易，且其利用非鉛金屬材料替換鉛金屬材料，可降低對海洋及魚類等自然生態環境的毒害污染。
