機構。[Claims for Utility Model Registration] 1. A linear drive mechanism in which a driven member is linearly moved via a nut member screwed onto the drive screw by rotating the drive screw, The driven member is placed at a position perpendicular to the plane and symmetrical with respect to the driving screw so that no rotational moment acts on the nut member within a plane that includes the central axis of the driving screw and the moving direction of the driven member. A linear drive mechanism, characterized in that it is swingably connected to the nut member. 2. The linear drive mechanism according to claim 1, which is characterized in that a guide member is provided in contact with the driven member to guide the movement of the driven member.
