PROBLEM TO BE SOLVED: To provide a terminal block device in which rain water on the upper surface of a terminal block cover can be prevented from flowing down into a terminal block chamber, even if the terminal block cover is in full open state during rainy weather.SOLUTION: Vertical gutters 23 are formed, respectively, in the sidewalls 14e of a terminal block chamber 14. A horizontal gutter 25 is formed in the width direction at an upper end of a terminal block cover 15. When the terminal block cover 15 is opened, the end of the horizontal gutter 25 abuts against the upper end of the vertical gutter 23 thus restricting rotation of the terminal block cover 15 in the opening direction. Furthermore, water on the upper surface of the terminal block cover 15 in open state flows down to the horizontal gutter 25 thence flows below the terminal block chamber 14 via the vertical gutter 23. |
