  • Driving apparatus
    Patent number: 8466603
    Abstract: A driving apparatus is capable of efficiently transmitting a reciprocating displacement of an electromechanical transducer element to a movement member and of effectively utilizing a vacant space. The driving apparatus includes an electromechanical transducer element having first and second end faces opposed to each other in a direction of expansion and contraction thereof, a vibration friction portion attached to the second end face of the electromechanical transducer element, and a movement member friction-bonded to the vibration friction portion. The movement member is movable along the direction of expansion and contraction of the electromechanical transducer element. The driving apparatus includes a vibration transmission member arranged between the second end face of the electromechanical transducer element and an end face of the vibration friction portion. A central axis of the electromechanical transducer element and a central axis of the vibration friction portion are not on the same line.
