<p>PROBLEM TO BE SOLVED: To provide an ultraviolet radiation device which facilitates adjustment of a shutter rotation angle.SOLUTION: The ultraviolet radiation device 1 comprises: an ultraviolet lamp; a first shutter 10A rotating around a first rotation shaft 11A; and a second shutter 10B rotating around a second rotation shaft 11B, and ultraviolet ray outputted from the ultraviolet lamp is blocked by closing the first shutter 10A and the second shutter 10B. The ultraviolet radiation device 1 further comprises: a first rotation body 23A rotating by an actuator; a second rotation body 23B rotating in synchronization with the first rotation body 23A; a first link 30A coupling the first rotation body 23A and the first rotation shaft 11A; and a second link 30B coupling the second rotation body 23B and the second rotation shaft 11B.</p> |
