Abstract
A pressure detecting apparatus comprises a pressure sensor having a vibrating element forming a pressure sensing surface, which is secured to a housing at the periphery thereof; and a pressure transmission member including an abutment portion having an abutment surface which is in contact with a position to be detected and a transmission portion projecting from the substantial center of the rear side of the abutment portion. The transmission member has the tip end surface area which is smaller than that of the pressure sensing surface of said pressure sensor. The transmission portion is secured to the substantial center of the pressure sensing surface of the said pressure sensor at the tip end surface thereof. The area of the abutment surface of said abutment portion being larger than that of the tip end surface of said transmission portion whereby said transmission member being adapted to transmit the pressure applied upon the abutment surface of said abutment portion to the pressure sensing surface of said pressure sensor via the tip end surface of said transmission portion.
