PROBLEM TO BE SOLVED: To provide a roof ventilation structure with a simple structure capable of effectively suppressing immersion of water into a building even under a strong wind.SOLUTION: A ventilation structure has an outer wall material 1, a roof substrate 2, a roof material 3, a ventilation hole 4, a ridge sash receiver 50, a ridge sash 5, a ventilation accessory 7 and a ventilation ridge cover 8. A ventilation space 9 communicating with the ventilation hole 4 is formed and an airflow space 10 is formed between the ventilation ridge cover 8 and the ventilation accessory 7. A roof side ventilation hole 11 and a wall side ventilation hole 12, which communicate outdoor and the airflow space 10, are formed. The ventilation accessory 7 comprises: a fixed part 71; a roof side inclined piece 72 that projects from the fixed part 71; a vertical piece 73 that projects from the fixed part 71; a roof side opening part 74 that penetrates the roof side inclined piece 72 to communicate the ventilation space 9 and the airflow space 10; and a wall side opening part 75 that penetrates the vertical piece 73 to communicate the ventilation space 9 and the airflow space 10. The ventilation accessory 7 has a first baffle plate 76, a second baffle plate 77, a third baffle plate 78 and a forth baffle plate 79.SELECTED DRAWING: Figure 1 |
