| 摘要 | PURPOSE: To provide a piezoelectric bimorph device whose driving conditions can be easily adjusted, by providing a rigid body movably in the direction vertical to the plane of the bimorph element. CONSTITUTION: A piezoelectric element 1 is received in a resin case 9 composed of a case body 92 and a cover 92. The piezoelectric element 1 is fixed with one end thereof fixedly interposed between an end edge of the case body 91 and an end edge of the cover 92. Two contact pieces 10a and 10b are inserted in the other end wall of the case body 91, and the bimorph element 1 is arranged such that the free end thereof comes into and out of contact with these contact pieces 10a and 10b. A partially threaded rod 4 is screwed through an internally threaded hole formed in the bottom of the case body 91, so that the position thereof can be easily adjusted. Accordingly, the driving conditions of the bimorph device can be adjusted easily and accurately even if only low power is generated by the bimorph element. COPYRIGHT: (C)1987,JPO&Japio |
