摘要： The object of the present invention is to further improve a lens barrel moving mechanism of a liquid crystal projector and to provide a lens moving mechanism which has simple structure and is capable of achieving the smooth and high precision movement of a lens barrel, and a liquid crystal projector employing the lens moving mechanism. The present invention provides a lens moving mechanism for moving a lens retaining member 20, which retains a lens barrel 15 provided therein with a projection lens for projecting light with image information, in the directions of Z axis and X axis. The lens moving mechanism comprises first and second guiding mechanisms 23, 23, 24, 24 including a track member, a movable member, and a plurality of rolling members arranged between a rolling member running surface of the track member and a rolling member running surface of the movable member, whereby the lens barrel 15 is guided by the first and the second guiding mechanisms 23, 23, 24, 24 in the directions of Z axis and X axis.

摘要： A sliding apparatus in which a first extension member and a second extension member are relatively movable in a longitudinal direction includes a restriction portion for restricting a movement range that allows the relative movement. The restriction portion includes: a projection portion that is formed integrally with the first extension member; and an engaging portion that is formed integrally with the second extension member. The projection portion has: a support portion; and a protrusion portion that is provided on a tip side of the support portion and is protruded toward the second extension member. The engaging portion has: a guide portion that guides the protrusion portion of the projection portion; and an abutting portion that abuts the protrusion portion. According to the present invention, it is possible to provide a sliding apparatus and a sliding structure that have a small number of parts, require no additional steps, significantly improve workability and productivity, and are capable of being disassembled in a simple manner and in a short time even after assembly.
