PROBLEM TO BE SOLVED: To provide a skylight opening/shutting mechanism improving ventilation efficiency and saving labor of opening/shutting. SOLUTION: This skylight opening/shutting mechanism is such that a guide roller 30 supporting a skylight 20 in a rolling manner is arranged on the rear of the skylight 20 and a guide rail 40 engaged with the guide roller 30 is arranged on a ceiling along the skylight opening/shutting direction. A rack 50 is fixedly arranged on the skylight 20 along the opening/shutting direction, and a pinion 60 geared with the rack 50 is arranged and connected with a rolling shaft 70 linked with a driving force. As a result, when the pinion 60 rolls, the skylight 20 fixed to the rack 50 moves to the slide direction together with the rack 50, and a ventilation opening part formed on the ceiling can be completely opened and the labor of opening/shutting the skylight 20 can be saved. |
