Claims

[Scope of utility model registration request]

In a wave receiver equipped with a piezoelectric element and a support fitting for supporting the piezoelectric element, a barrel-shaped piezoelectric element is formed by cutting off both ends of the concentric sphere symmetrically with respect to the spherical center of the concentric sphere with a concentric sphere having a hollow interior. and a dish-shaped support part is attached so as to be in close contact with the cut-off part, and both center parts of the dish-shaped support part are fixedly supported by a shaft of a support fitting, passing through the center of the hollow part of the barrel-shaped piezoelectric element.
