Driving member, linear driving device, camera device, and electronic device

摘要

A driving member, a linear driving device using the driving member, a camera device and an electronic device are provided. The driving member (10) includes a deformable thin plate (16) having a flexible thin plate (12) capable of expanding and contracting itself under the applied voltage and an elastic thin plate (14) having at least one side thereof rigidly fixed to the flexible thin plate (12) and a driving shaft (30) having its one axial end rigidly fixed to the deformable thin plate (16) and being capable of undergoing displacements that are operatively associated with the deformation of the deformable thin plate (16), wherein the driving shaft (30) has the lateral side portion (32) of the one axial end thereof rigidly fixed to the corresponding inner side portion of a through hole formed on the deformable thin plate (16).
