Drive device, lens part, and camera module |
摘要 |
A drive device capable of engaging a drive shaft and a part holding the drive shaft with a suitable force without accompanying increase in the size of the drive device. The drive device includes a couple member with a piezoelectric element and a transmission shaft coupled together, a lens holder that holds a lens and to which the couple member is secured, a biasing member that biases the transmission shaft in a direction intersecting a placement direction of the transmission shaft viewed from the lens holder (excluding a lengthwise direction of the transmission shaft), and a link member (link body) that holds the transmission shaft in a slidable manner together with the biasing member.
