The invention relates to an ant-proof device. A closed holding tank is concavely provided on the bottom end of an object holding main body, and a support portion is protruded from the center of the holding tank on the bottom end of the object holding main body. Furthermore, an ant-proof body is held in the holding tank of the object holding main body, and the ant-proof body surrounds the periphery of the support portion. Accordingly, it can prevent ants from crawling along the support portion to the top of the object holding main body by means of the simple and convenient design of the ant-proof device so as to prevent the foods placed in the object holding main body from being invaded and eaten by ants efficiently.本發明係有關於一種防蟻裝置,係於置物主體底端面凹設有封閉容槽,且使置物主體底端面位於該容槽中心凸伸有支撐部,又於該置物主體之容槽中容置有防蟻體,且使該防蟻體圍繞於支撐部周側,藉此,利用該簡便防蟻裝置設計,即可防止螞蟻沿著支撐部爬行至置物主體上方,以有效維護放置於置物主體上食物不致受螞蟻侵食效果。(1)...置物主體(11)...容槽(12)...支撐部(13)...穿孔(2)...防蟻體(21)...套孔(3)...止擋環(31)...第一止擋環(32)...第二止擋環
