Abstract
A reflective module includes a rotation plate supported by an internal wall of a housing; and a movable holder supported by the rotation plate and including a reflective member. The movable holder moves the reflective member in a first axis direction perpendicular to an optical axis and in a second axis direction perpendicular to the optical axis and the first axis direction. At least two ball members aligned in the first axis direction are disposed in at least one of a first gap between the housing and the rotation plate and a second gap between the rotation plate and the movable holder. A guide groove is disposed in the rotation plate and in at least one of the housing and the movable holder, and the ball members are inserted into the guide grooves. The ball members are inserted into and three-point supported by the guide grooves.
