PROBLEM TO BE SOLVED: To provide a misoperation preventing fixture for preventing misoperations of a handle due to human errors. SOLUTION: At the operation of inspection of an apparatus, when a handle 13 is turned to a lowermost part of a guide groove 12a, to make a circuit go into open state, a user attaches both end parts 22, 23 of a misoperation preventing fixture 20 to grooves 12b provided on both sides of a casing 12, respectively. The misoperation preventing fixture 20 locks the turning in the upward direction, by locking an upper part of the handle 13. A display part 21 is also provided on the wrong operation prevention fixture 20, an operating state and the purpose of operation of the handle 13 are displayed on the display part 21. Thus, since the misoperation prevention fixture 20 is attached on both sides of the casing 12, turning in the opposite direction to the handle 13 will be locked; and the operation state and the operation purpose will be displayed, the possibility of the handle 13 being misoperated by some other persons is reduced during the operation of the user.
