Classification: CPC G  H | IPC G  H

Claim 0:
1. An optical element driving mechanism, having an optical axis, comprising:
a movable part;
a fixed part, comprising a sidewall parallel to the optical axis; and
a driving assembly, driving the movable part to move relative to the fixed part, wherein the sidewall is not in direct contact with the driving assembly,
wherein the driving assembly comprises:
a deformation element, having a first end and a second end;
a piezoelectric element, in contact with the first end of the deformation element; and
a connecting element, clamped by the second end of the deformation element,
wherein the driving assembly drives the movable part to rotate about a direction perpendicular to the optical axis relative to the fixed part,
wherein the movable part comprises a fixing element, the movable part is movably connected to the fixed part via the connecting element and the fixing element, and the connecting element comprises:
a first part, having a first surface, the first surface facing away from the movable part;
a second part, having a second surface, the second surface facing the movable part, and a shortest distance between the second surface and the fixing element is longer than a shortest distance between the first surface and the fixing element,
wherein the second surface is in direct contact with the movable part.
