ていた。However, in the above-mentioned conventional lead-out structure, the cap 19 is not provided.
The entire area of the notch 13c cannot be closed by the flange 19b, and the notch 13c is exposed to the outside, so that airtightness in the instrument case 1 cannot be ensured. For example, when airtightness inside the instrument case 1 is required in an industrial machine or an agricultural machine used in a bad environment where sulfides are easily generated, the sulfide adheres to the instrument body 7 inside the instrument case 1 and the like. This causes a problem of corroding metal parts. Further, since the protruding wall 14 protrudes into the inside of the instrument case 1, space is wasted by the height H of the protruding wall 14, and the instrument case 1 is enlarged.
