Claims

[Scope of utility model registration request]

In an actuator, an actuating piece is attached to the tip of a driving part formed by bonding at least one piezoelectric element to an electrode plate, and the actuator is displaced by applying a voltage to the driving part, wherein one end of the electrode plate is connected to the piezoelectric element. In addition to protruding further, a notch is provided in the protrusion to form two opposing protrusions, and an opposing protrusion or recess is provided inwardly at the tip of the protrusion, while the tip of the drive unit is fitted into the operating piece. a matching recess;
An actuator comprising: a slide groove for sliding the inner side of the protrusion; and an engaging portion that engages with the convex portion or the concave portion when the drive portion is fitted into the concave portion.
