A lens unit for focusing light onto an image pickup device, including: a frame body; a first lens group having a first optical axis and being movable between an operating position and a storing position; a bending member for bending the light along the first optical axis to a perpendicular second direction and being held movable between a bend position and a retract position to create a space for storing the first lens group; a second lens group for leading the bent light to the image pickup device, and being held movable in the second direction; a moving tube which moves the first lens group; a stationary tube fixed on the frame body and having a feed member to move the moving tube, wherein the stationary tube has an opening through which the bending member moves between the bend position and the retract position.
