ABSTRACT:
A brake device for producing a braking force by pressing a friction member against a member to be braked in response to a deformation produced by applying a DC voltage to a piezoelectric element array including a stack of piezoelectric elements. A plurality of piezoelectic element arrays are coupled by a displacement transmission mechanism such that deformations produced by the piezoelectric element arrays are added together.
