PROBLEM TO BE SOLVED: To provide a structure which, in a pressure sensor used in a water-poured environment, prevents water from accumulating in the pressure instruction part of a case.SOLUTION: A case 30 has a pressure introduction part 35 composed of a front wall part 35a disposed in front of an introduction port 33 with a space therebetween, an upper wall part 35b and a pair of side wall parts 35c, 35d connected to the front wall part 35a, and an opening part 35e for introducing a pressure medium from below the introduction port 33. The front wall part 35a is inclined to the pair of side wall parts 35c, 35d due to that an opening end 35f constituting the opening part 35e is recessed in circular arc form to the upper wall part 35b. The upper wall part 35b is connected to the pair of side wall parts 35c, 35d, with the whole of it inclined toward upward of the introduction port 33 so as to form a convex shape. It is thereby possible to actively discharge the water splashing on the front wall part 35a or the upper wall part 35b. |
