Provided is a lens shifting device that has a simple structure and a small number of components, is compact and lightweight, and has high positional accuracy and slidability. The lens shifting device includes: first plate (12) through which video light passes; second plate (13) connected to first plate (12) via elastic member (23) and having projection lens (6) attached to a position into which the video light that passed through first plate (12) enters; slider (27) disposed to project from second plate (13) and housed in first plate (12) to be movable in a predetermined direction; and guide shaft (14) attached to first plate (12) in the state of being engaged with slider (27) and rotated to move the second plate. Elastic member (23) is disposed between first plate (12) and second plate (13) to connect first plate (12) and second plate (13) in the state of generating an elastic contraction force. |
