Abstract: A transfer apparatus of vessels in a tunnel furnace with a built-in heating apparatus is disclosed, comprising a horizontally reciprocative apparatus for carrier apparatus and vertically reciprocative apparatus for vessels. The vessels forward one stroke together with the carrier apparatus when the carrier apparatus forwards, and the vessels are lifted up during returning the carrier apparatus to the former portion, then the vessels are felled on the returned carrier apparatus. The vessels forward one stroke at every one reciprocation movement of the carrier apparatus during backing or heating treatment of material contained in the vessels in the furnace.
