Claim 17:
18. A light path adjustment mechanism, comprising:
a support;
a carrier disposed on the support and connected to the support via a first flexible member and a second flexible member, the first flexible member and the second flexible member being disposed on two opposite sides of the carrier, the first flexible member being connected to the support via a first fixed point, the second flexible member being connected to the support via a second fixed point, the carrier being connected to the first flexible member via a first connection point and a second connection point on an outer periphery of the carrier, and the carrier being connected to the second flexible member via a third connection point and a fourth connection point on the outer periphery of the carrier; and
an optical plate member disposed on the carrier and capable of being tilted about at least one of a first axial direction and a second axial direction, the first connection point and the second connection point being disposed on two opposite sides of the first axial direction, a distance between the first fixed point and the first connection point measured in the first axial direction being smaller than a total length measured from a reference point to the first connection point, the reference point being an intersection point crossed by a virtual line extending from the first fixed point in a direction parallel to the second axial direction and a virtual line extending from the first connection point in a direction parallel to the first axial direction, and the total length is a sum of lengths of all sections of the first flexible member connected between the first connection point and the reference point.
