Abstract
A liquid coating apparatus includes a liquid chamber, a diaphragm deformable to change a volume of the liquid chamber, a piezoelectric element that deforms the diaphragm in a thickness direction, a pressurized casing bottom-wall portion between the piezoelectric element and the diaphragm to support the piezoelectric element from a diaphragm side, a fixed casing bottom wall portion that supports an end of the piezoelectric element on a side opposite to the diaphragm, a plunger that extends through the pressurized casing bottom-wall portion and transmits expansion and contraction of the piezoelectric element to the diaphragm, and a coil spring that is between the piezoelectric element and the pressurized casing bottom-wall portion and is supported by the first support portion to apply a compressive force to the piezoelectric element.
