Title:
LENS DRIVING DEVICE AND CAMERA MODULE
Document Type and Number:
WIPO Patent Application WO/2022/163560
Kind Code:
A1
Abstract:
A lens driving device (101) has a lens holding member (2) driven by the vibration of a piezoelectric element (8). A biasing member (6) has: a fixed portion (6F) formed from a plate spring member and fixed to a base member (7); a support portion (6S) for supporting a piezoelectric drive portion (PD); and an elastic deformation portion (6E) provided between the fixed portion (6F) and the support portion (6S) so as to be elastically deformable. The support portion (6S) has: a sheet-shaped base portion (6B) connected to the elastic deformation portion (6E); and a bent portion (6N) bent from the base portion (6B) in an L shape and protruding toward the lens holding member (2) side. The piezoelectric drive portion (PD) is fixed to the bent portion (6N).
