Abstract
A pressurizing unit for pressurizing ink filling a pressure chamber in response to an electric signal is constructed with a beam and a support portion. The support portion is preferably formed integrally with the beam and supports the beam at opposite end portions thereof. The support portion receives a bending force and a shearing force, with are generated at the opposite end portions by a buckling deformation of the beam when the beam is expanded in its longitudinal direction by an application of the electric signal.
