PROBLEM TO BE SOLVED: To provide a control panel enclosure adopting a member tightening structure capable of ensuring sufficient rigidity / strength in spite of a low manufacturing cost and safely applying testing and adjustment or the like to a draw-out type unit. SOLUTION: A lateral middle frame 6 placed laterally in the middle of the rectangular solid shaped control panel enclosure 101 in the vertical direction and tightened to left and right side plates 1, 1 and a rear member 140 by rivets 11, and a longitudinal middle frame 7 longitudinally placed in the middle in a horizontal direction above the lateral middle frame 6 and tightened to the rear member 140 and a lateral member 150 by rivets 11 are provided to the inside of the control panel enclosure 101. Through the configuration above, since the lateral middle frame and the longitudinal middle frame are placed inside of the rectangular solid enclosure and tightened to the adjacent members by the tightening members, the rigidity / strength of the enclosure in the horizontal direction can be enhanced and the rigidity / strength against torsion can be improved.
