摘要：PURPOSE:To obtain a displacement amplification mechanism of a piezoelectric effect element with a simplified mechanism and a low production cost by utilizing a volume inflation which is generated by aling the piezoelectric effect element in a vesl which is filled with fluid and applying a voltage. CONSTITUTION:A piezoelectric effect element 1 exists in a vesl 3, furthermore, the vesl 3 is filled with a fluid 2, and then a volume of the piezoelectric effect element 1 inflates when a voltage is applied to the piezoelectric effect element 1 externally. This inflation allows pressure of the fluid 2 within the vesl 3 to be incread. The increa in pressure of the fluid 2 caus a tip of bellows 5 to be deformed toward an external portion of the vesl 3, a displacement take-out portion 6 to be pushed up, and then the displacement to be taken out.
