Claims

[Scope of utility model registration request]

A diaphragm formed into a bag-like shape made of an elastic material, the inside of which is vacuum-sealed, and maintained in equilibrium with atmospheric pressure by the elasticity of the elastic material, and a cantilevered leaf spring that engages with the operating part of the diaphragm. and a strain gauge that is installed on the leaf spring and converts changes in strain in the leaf spring into electrical signals.
