Document Type and Number:
WIPO Patent Application WO/2024/048011
Kind Code:
A1
Abstract:
Provided are an optical element driving device, a camera module, and a camera mounting device that are highly reliable and are capable of achieving stable movement actions of a movable unit. The optical element driving device comprises: a fixed part; a movable part that includes an optical element; an ultrasonic motor-type driving part that is disposed on an active-side member made up of any one among the fixed part and the movable part, and causes the movable part to move with respect to the fixed part; and a power transmitting part that couples a passive-side member made up of the other among the fixed part and the movable part, and the driving part, and transmits the power of the driving part to the passive-side member. The driving part has a resonating part that has a pair of arms that vibrate. The motive power transmitting part has a passive member that is gripped while being urged by the pair of arms, and a coupling member that couples the passive member and the passive-side member. The coupling member is elastically deformable.
