Abstract
A pressure sensing apparatus for a vehicle may include: a sensor element configured to measure a change in air pressure by a vehicle collision; a housing unit into which the sensor element is seated, and including a terminal unit electrically coupled to the sensor element, the housing unit being fixed to a vehicle body; a cover unit removably installed on the housing unit; and an elastic pressing unit including a first end coupled to the cover unit, and a second end protruding toward the sensor element and pressing the sensor element, the elastic pressing unit being made of elastically deformable material. An area of a pressing surface of the elastic pressing unit that faces the sensor element may be equal to or less than an area of a surface of the sensor element that faces the pressing surface.
