Claims

[Claims for Utility Model Registration] A pressure introduction port is formed, a part of the pressure introduction port has a cylindrical protrusion formed inside, and the pressure introduction port has a cylindrical shape that covers the outside of the protrusion. A casing member having an outer cylindrical portion formed; a thin flexible portion provided at a position facing one end of the pressure introduction port substantially in the center thereof, supporting the flexible portion and surrounding the casing member; A detection member in which a cylindrical thick part arranged in a covering manner is disposed in a space between the protrusion part of the casing member and the outer cylinder part; the thick part of the detection member is flush with the inner peripheral wall. an annular groove formed at a corner where the end face intersects; an annular groove disposed in a space formed between the outer periphery of the protrusion of the casing member and the groove of the detection member;
A pressure sensor comprising: an annular seal member; and a deflection detection means attached to a flexible portion of the detection member.
