PROBLEM TO BE SOLVED: To provide a support mechanism achieving both elastic contact for the manifold of a lid and airtight retention. ! SOLUTION: A support mechanism for supporting a lid that seals the throat of a heat-treating furnace by the lift using lifting means or releases sealing includes a first elastic body having a first elastic modulus, and a second elastic body having a second elastic modulus larger than the first elastic modulus. When the lid lifted by the lifting means comes into contact with the throat, a reaction related to the first elastic body is applied to the lid, and after the lid lifted by the lifting means comes into contact with the throat, a reaction related to the first elastic body and second elastic body is applied to the lid. !
