PROBLEM TO BE SOLVED: To provide a packing for an autoclave which keeps adhesiveness between a recess groove and an inner wall surface and has sufficient durability even when a slide-contact surface slide-contacting with the inner wall surface of the recess groove is worn away, by inserting the packing into the recess groove formed along the periphery of the opening of a sterilization chamber in a state where the packing can be put out and in. SOLUTION: The packing for an autoclave 50 is used for an autoclave which sterilizes a matter to be sterilized which is housed in the sterilization chamber whose opening is sealed with a door. A packing main body 52 consisting of elastic material is inserted to the annular recess groove 22 formed along the periphery of the opening of the sterilization chamber in the state where the packing can be put out and in so that its distal end face may abut on the door which seals the sterilization chamber and is pushed out by the fluid pressure of a working fluid fed to the bottom face side of the groove 22. As for the packing main body 52, an end part to be inserted to the groove 22 is formed to be tapered parts 54 and 54 which become wider in the direction of the bottom face side of the groove 22 so as to slide-contact with the inner wall face of the groove 22. When a slit-like recess part 58 extending in a longitudinal direction is bored on the bottom face side of the groove 22 and the tapered parts 54, 54 are pressurized to close the opening of the recess part 58, a hollow part is formed on the bottom side of the recess part 58.
