DRIVE DEVICE AND IMAGING APPARATUS |
| 摘要 |
There is provided a drive device including a movable body, and a fixing member that supports, with a drive shaft driven by a piezoelectric element expanded and contracted in response to an applied voltage and a sub shaft provided in parallel with the drive shaft, the movable body connected with the drive shaft movably in an axial direction. The movable body includes a rotation regulating member that supports the sub shaft and regulates rotation of the movable body with the drive shaft as a rotation center, and an impact dispersing part that disperses an impact on the piezoelectric element when inclined to the drive shaft. |
