To provide a ventilator solving an action failure, etc., due to rust or abrasion after the lapse of time without any damage to a vertical wall.SOLUTION: A ventilator A is composed of a ventilator body 1 attached to a vertical wall, a cover 2 closing a lid on an opening unit of the ventilator body 1, and a hinge 3 supporting the cover 2 to be freely opened/closed, wherein an engaging pin 24 is attached to the cover 2, and a hook 5 for hooking the engaging pin 24 is provided on the hinge 3. The ventilator body 1 is a curved cylindrical body with a tip opened downward. Although the cover 2 in a lid open tends to be in a state of hanging down and shaking, since the shaking is capable of being stopped by the engaging pin 24 and the hook 5, damage such as peeling of coating of the vertical wall by the cover 2 can be prevented. Since there is no need to attach the hook 5 to the vertical wall, the ventilator A with the cover 2 is capable of being installed even in a narrow space.SELECTED DRAWING: Figure 1

    【課題】立壁の損傷が無く、経年後の錆や摩耗による動作不良等を解消した通風筒を提供する。【解決手段】立壁に取付けられる通風筒本体1と、通風筒本体1の開口部を閉蓋するカバー2と、カバー2を開閉自在に支持するヒンジ3とからなる通風筒Aであって、カバー2には係合ピン24が取付けられており、ヒンジ3には、係合ピン24を掛止しておくフック5が設けられている。通風筒本体1は湾曲した筒体であって、先端が下向きに開口している。開蓋状態のカバー2は垂れ下がって揺れ動く状態となりやすいが、係合ピン24とフック5によって揺れを止められるので、カバー2によって立壁の塗装を剥がすような損傷を防止できる。立壁にフック5を取付ける必要がなく、狭い空間にでもカバー2付きの通風筒Aを設置できる。【選択図】図1
