る。A hook 4 made of a spring plate whose tip is bent in a hook shape is attached to the inside of the cover 2. The tip prevents the cover from dropping and opening. FIG. 3 is an explanatory diagram showing a method of opening the cover 2. FIG. 3 shows a state in which the set screw 3 is removed and the hook-shaped tip of the latch 4 is hooked on the edge 1A of the housing 1 to prevent the cover 2 from dropping and opening. In this state, when the latch 4 is pushed and bent in the direction of arrow C so as to be detached from the edge 1A of the housing 1, the hook is released and the cover can be opened.
