Abstract
A leaf springconstituting an elastic member one end of which is fixed to a foundation, and other end of which is brought into contact with a laminating type piezoelectric elementor a driven memberis constituted such that a thickness is thinned from a side of the foundationto a side of the laminating type piezoelectric elementto make a moment of inertia smaller on a side of a portion of other end held by the laminating type piezoelectric elementthan a portion on one end side fixed to the foundation. Further, a strain gage sensoris attached to a side faceof the leaf springconstituting one face of one end of the leaf springproximate to the laminating type piezoelectric elementorthogonal to a direction of elongating and contracting the laminating type piezoelectric elementconstituting a side of the driven member
