Abstract
A controlling device for stopping the drawing out of drawer type unit cases holds the unit case at a predetermined position by interlocking a latch with one of a pair of interlocking holes of a partition upon turning an operating shaft through a predetermined angle. The operating shaft has a square part and higher step parts at both sides of the square part and a U-shaped leaf spring is contacted with the square part so as to control the free movement of the operating shaft.
