Abstract:
1. An ultrasonic atomizing unit comprising: an atomizing member comprising: a first O-ring and a second O-ring, each having a cross-sectional diameter; and a holding member elastically sandwiching and holding the atomizing member through the first and second O-rings only in a direction perpendicular to the first and second surfaces of the atomizing member, wherein the first O-ring is arranged so as to extend along the first surface of the atomizing member so as to be concentric with the atomizing member, and the second O-ring is arranged so as to extend along the second surface of the atomizing member so as to be concentric with the atomizing member, wherein a maximum cross-sectional diameter of each O-ring is 40% of the radial direction width of the piezoelectric vibrator.
