Abstract
A linear driving mechanism capable of moving a driven object smoothly and lengthening its service life. A first vibration element and a second vibration element sandwich a friction member therebetween. A first holding member holding the first vibration element is rotatably supported by a first shaft. A second holding member holding the second vibration element is rotatably supported by a second shaft. An urging part moves the first holding member and the second holding member to press these vibration elements against the friction member. A coupling member couples the first holding member with a driven object. A pressing part presses the coupling member against a moving body including the first and second holding members. A direction of a pressing force of the pressing part intersects with the first shaft when the coupling member couples with the first holding member.
