PROBLEM TO BE SOLVED: To improve safety by providing a locking means preventing the pening of a cover when a temperature in the neighborhood of a conductor in a conductor housing exceeds a prescribed value to prevent the opening of the cover at the time of high temperature sterilization or after finishing sterilization to avoid touching the conductor at a high temperature. SOLUTION: The preparation of sterilization is completed by allowing a user to finish the cure, to stick the conductor to a housing part 23 and covering with the cover 20. Next, a heater is energized by pressing a sterilizing switch and the temperature of the conductor is raised by this energizing of this heater to start the sterilization of the conductor at the time of becoming about 70 deg.C. At this time, the temperature of the part 23 becomes about 50 deg.C to make the force of a shape memory flat plate 32 trying to curve stronger than the force of a flat plate 31 trying to be straight to deform a regulating plate 30 by the shape memory operation of a shape memory alloy. At this time, the opening of the cover 20 is prevented by catching the plate 30 by a pawl 26. |
