Oscillator holding mechanism, oscillation motor, and lens driving device
Abstract:
An oscillator holding mechanism capable of generating a stable vibration in an oscillator and an oscillation motor having the oscillator holding mechanism are disclosed. The oscillator holding mechanism present within an oscillation motor includes an oscillator that has a protruding output section on one end that generates a predetermined movement in the output section by vibration, a holding member that holds and accommodates the oscillator, and a buffer member that is made of an elastic material and is provided between the oscillator and the holding member. The buffer member has a first surface in contact with the holding member having a larger area than a second surface in contact with the oscillator and a cross sectional shape including a center axis that connects a center point of the first surface and a center point of the second surface that is axisymmetric with respect to the center axis.
