Abstract:
1. A microactuator which drives a driving objective, the microactuator comprising: a base member; a plate-shaped member which is deflectively deformable and which is supported by the base member; and a driving force applying device which applies a driving force to the driving objective; wherein the plate-shaped member is fixed to the base member at a predetermined place and the plate-shaped member is deflectively deformable in a deflectively deformable area which is different from the predetermined place of the plate-shaped member; the driving objective is connected to a predetermined portion of the deflectively deformable area of the plate-shaped member on one side of the plate-shaped member, the base member being arranged on the other side of the plate-shaped member; the driving force applying device deflectively deforms the deflectively deformable area of the plate-shaped member to change an inclination of the predetermined portion of the plate-shaped member between a first inclination and a second inclination; and a part of the plate-shaped member or a part of a member fixed to the plate-shaped member is brought into abutment against a member which is different from the base member and which is different from the driving objective when the inclination of the predetermined portion is the first inclination, and the part of the plate-shaped member or the part of the member fixed to the plate-shaped member is brought into abutment against the base member when the inclination of the predetermined portion is the second inclination.
