PURPOSE:To prevent a defect due to the separation of bonding by displacing in response to the dimensional distortion transmitted from a drive member through a connecting member, and providing a displacement transmitting mechanism for transmitting the wire member for printing. CONSTITUTION:A recess for engaging the end of a piezoelectric element 4 is formed on the bonding surfaces of connecting members 22, 23 for bonding the both ends of the element 4. The both side projections of the recess are formed to cover the two opposite sides of the element 4 when the element 4 is engaged. The members 22, 23 and the element 4 are bonded by bonding materials 12, 13, respectively. When the portion in which not only the end face of the element 4 but also the both side projections of the members 22, 23 are coated is bonded by the materials 12, 13, the bending deformation of a protective layer 45 is suppressed at the operating time to reduce the stress acted on the materials 12, 13. |
