PROBLEM TO BE SOLVED: To provide a housing box of an electric apparatus wherein a small window door which can be positionally kept in open state and closing state is engaged rotatably by a single axis member. SOLUTION: A small window door 5 is engaged rotatably by a bar-like axis member 11 in a small window 4 formed in the cover 2 of the housing box of an electric apparatus. The bar-like axis member 11 penetrates the small window door 5, and its both ends are engaged with the engaging holes 13 of both side walls 6 of the small window 4, and then its central part is engaged with the rear projection 14 of the small window door 5, thereby pressing the small window door 5 in the direction of inner side ends by its elasticity. When the small window door 5 is in an intermediate state between opening and closing, the corners of a peripheral wall 10 of the small window door 5 hit the bottom 9 of the small window and is pressed outward, so that the small window door 5 can be stably kept in place in open state and closing state thanks to the elasticity of the bar-like axis member 11.
