PROBLEM TO BE SOLVED: To provide a locking mechanism for a button case capable of producing at low cost and miniaturizing and being in a simple structure and facilitating an assembling operation. SOLUTION: A case 20 includes a main body 21, a control circuit board 22, a control switch 23, and buttons 24. The locking mechanism 30 limits control of an ON and OFF state of the control circuit board 22 of the control switch 23. The locking mechanism 30 has a lock switch 31, a pivot button 32, and a lock body. The lock switch 31 is electrically connected with the control switch 23 in series, and is located at one position between an ON position and an OFF position. The lock body is arranged in a convex shape at one end of a pin so as to shift from an axis of the pin of the pivot button 32, and can move between a lock position and a release position according to rotation of the pivot button 32.
