PROBLEM TO BE SOLVED: To provide an air pot in which the rotating operation of a lock ring for locking and unlocking of a push button is hardly influenced by the deformation with time of a lid body. SOLUTION: The warping deformation in a vertical direction is not hardly generated in a ring receiver 32 due to the deformation with time of the lid body by forming the ring receiver 32 in the upper lid 11 while extending the same from the inside of the outer shell peripheral side portion of the lid body 1, and the rotating operation of the lock ring is hardly influenced by the deformation with time of the lid body by mounting the lock ring 31 on the ring receiver 32 and rotatably supporting the same. Further, the upper lid 11 is constituted as the combined body of a lid ring member 33 in which the outer shell peripheral side portion of the lid body 1 is formed to keep the ring receiver 32 is exposed to the upper face and an upper cover member 35 thereby to make it easy to incorporate the lock ring 31, and the engaging portion 38 of the connecting wall 32b of the ring receiver 32 and the connecting wall 36 of the upper cover member 35 are engaged in a vertical direction, a lateral wall 32a is insulated under the engaging portion 38 of the same, and thereby the lateral wall 32a is prevented from being influenced by the engagement.
