PROBLEM TO BE SOLVED: To provide a lock structure of a handle body preventing the opening and closing of a door without notice by controlling the rotary operation of the handle body for opening and closing the door rotatably installed on the front of the door in the horizontal direction while smoothly conducting the rotary operation of the handle body. SOLUTION: Since the lock structure of the handle body is composed of a cover body 2 being detachably covered to the handle body C for opening and closing the door rotatably mounted on the front of the door B in the horizontal direction and controlling the rotary operation of the handle body C and a locking mechanism for maintaining the state in which the handle body C is covered with the cover body 2, the rotary operation of the handle body C for opening and closing the door is controlled by the simple operation of the covering of the handle body C with the cover body 2, and the opening of the door B without notice can be prevented surely.
