That is, when the optical path bellows is shrinked, air in the transmission passage is exhausted from air exhausting means 12. On the other hand, when the optical path bellows 3 is expanded, the air is supplied into the transmission passage from suction means 13 and the inner part in transmission passage can be held cleanly.
