Claims

[Claims for Utility Model Registration] 1. Two parallel elastic plates, one end of which is fixed to a fixed member with a predetermined spacing between them, the other ends of which are connected by a connecting member; A bimorph plate made of electrostrictive material is fixed to the fixing member described above so that it is parallel to the two elastic plates, and the other end is fixed to the intermediate position between the two elastic plates. A fixing member for a first unit driving member in two sets of first and second unit driving members, each of which has a structure whose end portion is flexibly connected to the above-mentioned connecting member as a unit driving member. The connection member of the first unit driving member is fixed to the fixed part of the device, and the elastic plates of the first unit driving member and the second unit driving member are arranged in parallel with each other. A driving device for a recording/reproducing element, comprising: a second unit driving member and a fixing member fixedly connected to each other via a spacer; and further, a recording/reproducing element is attached to a free end of the second unit driving member. 2. Fixing one end of the elastic plate and one end of a bimorph plate of electrostrictive material provided parallel to the elastic plate at a predetermined interval to a fixing member,
