<p>The present invention relates to a pressure sensor. The present invention prevents abnormal materials in a vent flow path (34) which removes a pressure difference between an internal space (30), formed within a housing (10) of the pressure sensor, and the outside. The vent flow path (34) is formed to penetrate the housing (10) and connects the inside to the outside of the housing (10). One side end of the vent flow path (34) is positioned at a bottom recess part (37) opened in a direction facing a surface of a fixed part of a car where the housing (10) is installed among the surface of the housing (10). Therefore, if the housing (10) is installed in the fixed part of the car, the bottom recess part (37) is shielded from the external environment and external abnormal materials are not transmitted to the vent flow path (34). Both side opened parts of the vent flow path (34) are positioned at an inner protruding end (35) and an outer protruding end (38) formed on an inner side and an outer side of the housing (10) respectively, such that moisture is guided along an edge of the inner protruding end (36) and the outer protruding end and is not transmitted to the vent flow path (34), thereby preventing moisture from being transmitted to the vent flow path (34).</p> |
