Abstract

An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion, a fixed portion, a first driving assembly, and a plurality of second guiding members. The first movable portion is configured to connect an optical member. The optical member is used for adjusting a direction of a light from an incident direction to an outgoing direction. The first movable portion can move relative to the fixed portion. The first driving assembly is configured to drive the first movable portion to move relative to the fixed portion. The second guiding members include a first ball, a second ball, and a third ball. The first ball, the second ball, and the third ball are disposed in a plane that is perpendicular to the incident direction.
