Claim 5:
6. The optical element driving mechanism as claimed in claim 5, wherein the optical element driving mechanism further includes at least one first guiding assembly which is in direct contact with the guiding rod, and the first guiding assembly includes at least two first guiding elements disposed in the first loading part of the first movable assembly;
the first guiding elements are configured to be in contact with the guiding rod;
when viewed in the first direction, the first magnetic element is located between the first guiding elements and a first permeability element of the first driving assembly;
when viewed in the first direction, an included angle formed by a line connecting centers of the first guiding elements and the guiding rod is greater than 0 degrees and less than 180 degrees;
each of the first guiding elements has a spherical structure;
at least two first grooves are formed in the first loading part, and the first guiding elements are respectively fixed in the first grooves;
when the first movable assembly moves along the guiding rod, the first guiding elements do not rotate relative to the first grooves;
a plurality of first guiding assemblies are disposed in the first loading part and are arranged in the first direction;
the first loading part contacts the guiding rod only through the first guiding assemblies;
the optical element driving mechanism further includes at least one second guiding assembly disposed in the second loading part, and the guiding rod passes through the second guiding assembly;
when viewed in the first direction, the second guiding assembly includes a first contacting slope, a second contacting slope, and a middle surface;
the middle surface is not parallel to the first contacting slope;
the middle surface is connected to the first contacting slope and the second contacting slope;
when viewed in the first direction, the second magnetic element of the second driving assembly is located between the first contacting slope and a second permeability element of the second driving assembly;
the second driving assembly has a second pressing assembly configured to generate a magnetic attraction force or a repulsive force to drive the guiding rod to be in contact with the first contacting slope;
the first contacting slope and the second contacting slope are configured to be in contact with the guiding rod;
when viewed in the first direction, the included angle between the first contacting slope and the second contacting slope is greater than 45 degrees and less than 180 degrees;
a plurality of second guiding assemblies are disposed in the second loading part and are arranged in the first direction;
the second loading part contacts the guiding rod only through the second guiding assemblies.
