Abstract
A micro actuator including: a translationally driving section having a moving portion which is incorporated in a case 14 and moves translationally; and a displacement enlarging member 1 having one end portion 1g connected to the moving portion of the translationally driving section and another end portion 1h connected to the case, wherein as the one end portion 1g is pulled on the basis of the translational movement, the amount of displacement of its distal end 1a is enlarged.
Claims12
A micro actuator characterized by comprising:
- a translationally driving section having a moving portion which is incorporated in a case and moves translationally;
- and
- a displacement enlarging member having one end portion connected to said moving portion of said translationally driving section and another end portion connected to said case, wherein as said one end portion is pulled on the basis of the translational movement, said displacement enlarging member is extended from said end portion and said one end portion more than an amount of said translational movement, and an amount of displacement of its common distal end is enlarged.
A micro actuator characterized by comprising:
- a translationally driving section having a moving portion which is incorporated in a case and moves translationally;
- and
- a displacement enlarging member including a common portion having a distal end in common, at least two side portions extending from said common portion and opposing each other, and an open portion which is located on a side away from said common portion and is open,
- wherein one end of said open portion is connected to said translationally driving section, another end of said open portion is connected to said case, and said distal end is subjected to enlarging displacement on the basis of the translational displacement of said translationally driving section.
