PROBLEM TO BE SOLVED: To increase the degree of freedom for mounting. SOLUTION: At the left and right corners in the upper portion of a front panel 2 of a mounting plate for watt-hour meter, mounting holes 3 and 3 for screws 4 and 4 are formed, and below each mounting holes 3 and 3 two long hole groups 5 and 5 are formed respectively. The long hole group consists of four long holes 6, 6, etc., which position their outside end portions on perpendicular lines through the upper mounting hole 3 and 3 and are inclined obliquely upward in the direction toward the center side of the front panel 2, standing close in an equal space in the perpendicular direction. It is possible to insert the screw 8 into any long hole 6 selected.
