Mutually facing end faces of the second connector block and the second lens holder are provided with respective V-shaped grooves extending along the X-axis direction, the roller being interposed between the V-shaped grooves. Each of the adjuster screws includes a head engaged with the second lens holder in a manner capable of relative movement in the X-axis direction and a shaft screwed into the second connector block.
