う惧れがあり、安全を損なうことがあつた。 However, in this type of terminal box, a gap a may be formed between the outer wall 2 of the box body 1 and the lid body 4 due to deformation, warpage, etc. during molding. In such a case, since the lid 4 can move left and right with respect to the box 1, a screwdriver 8 is inserted through the tool insertion hole 7 of the lid 4 as shown in FIG. When rotating the screw 9, there is a risk that the screwdriver 8 may press the cover body 4 in the left and right directions due to an operational error, which may cause the engagement pawl 3 to accidentally come off from the locking hole 6, which is a safety issue. There were cases where the damage occurred.
