Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a natural ventilation window capable of obtaining different touches in a handle operation from a closed state to a natural ventilation state and a handle operation from the natural ventilation state to a smoke exhaustion state, and reducing a turning angle of a handle from the closed state to the natural ventilation state and the smoke exhaustion state.SOLUTION: A handle 53 freely switches a sash 19 from the closed state to the natural ventilation state and the smoke exhaustion state by a unidirectional turning operation. In one gear 57 and the other gear 59, large diameter parts 57a and 59a and small diameter parts 59b are coaxially and integrally provided respectively. Each small diameter part 59b is an intermittent gear partially lacking teeth, the large diameter part 59a of the other gear 59 is engaged with a rack 51a, the large diameter part 57a of the one gear 57 and the small diameter part 59b of the other gear are engaged in the handle operation for a change from the closed state to the natural ventilation state, and the small diameter part of the one gear 57 and the large diameter part 59a of the other gear 59 are engaged in the handle operation of changing the sash 19 from the natural ventilation state to the smoke exhaustion state.
