In the conventional technology, since the guide 4 is a metal shaft, excessive stress is applied to the cylindrical piezoelectric actuators 1 and 3, which causes wear and tear of the cylindrical piezoelectric actuators 1. The present invention solves these problems, and its purpose is to provide a guide that does not allow the stress exerted by the cylindrical actuator on the guide to exceed the necessary limit. be.
