Claims

[Scope of Claim for Utility Model Registration] A longitudinal guide member, which is arranged at intervals across the longitudinal guide member,
A gripping means equipped with a piezoelectric element having a bimorph structure that can grip the longitudinal guide member and maintain or release the gripping state; a traveling drive means equipped with a piezoelectric body capable of expanding and contracting; and a traveling drive means that extends or expands and contracts with only one of the gripping means being held between the longitudinal guide members, and then only one of the other gripping means; 1. A piezoelectric device for driving, comprising: a piezoelectric body control means for extending/contracting or expanding the traveling drive means in a state where the traveling drive means is held between longitudinal guide members.
