Abstract
A projection optical instrument includes a light source unit, a projection optical member and a support part. The light source unit emits light. The projection optical member transforms the light emitted from the light source unit into projection light. The support part supports the projection optical member to be movable with respect to the light source unit in at least one direction orthogonal to an optical axis direction of the light source unit. When vibration is applied to at least one of the light source unit and the projection optical member, the projection optical member accordingly vibrates with respect to the light source unit in a direction orthogonal to the optical axis direction of the light source unit.
