<P>PROBLEM TO BE SOLVED: To secure high airtightness in the case that a lead wire is connected to a piezoelectric stack. <P>SOLUTION: In the piezoelectric actuator where one end of the lead wire 3 is connected to the piezoelectric stack and the other end of the lead wire 3 is taken out of a casing 2, for a rubber bush 4, which performs sealing between the lead wire 3 and the casing 2, a core insertion hole 412 is made which abuts on the inserted core wire 31 of the lead wire 3. Then, the sealing between the rubber bush 4 and the lead wire 3 is made by the abutment between the core insertion hole 412 and the core wire 31. <P>COPYRIGHT: (C)2008,JPO&INPIT |
