Abstract
Structure for transmitting displacement of a piezoelectric element includes a piston member. A distal-end plate portion has a receiving face adapted to be brought into direct contact with a distal-end face of the piston member. The distal-end face of the piston member is brought into direct contact with a mating member at a displacement transmitting face which is situated on an opposite side to the receiving face. End faces of a piezoelectric element in a displacement direction are maintained substantially in parallel to each other while the piezoelectric element is being driven. The contact configuration between the distal-end face and the receiving face is an annular and linear contact condition, whereby the piezoelectric element, the piston member and the distal-end plate portion are constructed so as to remain substantially stationary while the piezoelectric element is being driven.
