Estimating the term…
An actuator using an electromechanical transducer capable of maintaining stable driving function even under a severe environment of high temperature and/or high humidity, or the like, and an apparatus mounted with the actuator. The actuator are disclosed is constituted to move a slider block frictionally coupled to a drive shaft in a predetermined direction by reciprocating oscillation having different speeds of the drive shaft driven by elongation and contraction displacements of a piezoelectric element and the piezoelectric element, a portion where the piezoelectric element is coupled to the drive shaft and a portion where the piezoelectric element is coupled to a frame is sealed by silicone resin, fluorinated resin or the like to thereby protect them from the high temperature and/or high humidity environment.
An actuator using an electromechanical transducer comprising:
An actuator using an electromechanical transducer according to claim 13, wherein said hole is elongated in a direction orthogonal to the predetermined direction of movement.
An apparatus having an actuator using an electromechanical transducer as a drive source, said apparatus comprising:
