アン。[Claims for Utility Model Registration] (1) A piezoelectric bimorph vibrator comprising a pair of plate-shaped piezoelectric elements and a thin metal plate whose both ends are bent in the same direction in a U-shape is sandwiched between the piezoelectric elements. and pasting elastic thin plates to the bent portions at both ends of the metal thin plate,
Furthermore, a piezoelectric fan is provided in which a central portion of the piezoelectric bimorph vibrator is fixedly supported by a support portion in a direction orthogonal to the direction of the bent portion of the thin metal plate. (2) The piezoelectric fan according to claim 1, which has been registered as a utility model, wherein convex portions are integrally formed with the thin metal plate at the center of both ends in a direction orthogonal to the direction of the bent portion of the thin metal plate. (3) The piezoelectric fan according to claim 2, wherein the convex portion is provided with a hole or a U-shaped notch.
