The front side bottom part of the outer box 1 is provided with square-shaped slit-shaped long holes 5, a bottom side part 4a in the hook shape of a fixed angle 4 is inserted into the long hole 5, a rising part 4b of the fixed angle 4 is set along a front wall 3a of a unit 3, and the fixed angle 4 is slid along the long hole 5 of the outer box 1. By the sliding, a gear-lock end 4c of a hook-shaped bottom side part 4a of the fixed angle 4 is engaged with the outer box 1 for fixing.
