Claims

[Scope of utility model registration request]

a housing having a bag-shaped inner shape; a pressure-sensitive element made of a piezoelectric body disposed on the bottom surface of the housing; and a diaphragm sealing the bag-shaped entrance of the housing;
A pressure receiving column serving as a pressure medium is provided between the diaphragm and the pressure sensing element, and a locking protrusion is engaged with one of the diaphragm and the pressure receiving column, and the locking protrusion is engaged with the other. 1. A pressure detector, characterized in that the pressure-receiving column is fixed to the pressure-receiving column by receiving a hole portion and using the retaining hole portion and a front arrangement locking protrusion.
