The roof ventilator structure has a locking ratchet (28) at least on the outer side of the cup (22) towards the eaves and at the inner side of the pan (24), with a longitudinal sawtooth contour. A second ratchet lock (26) is concentric to the joint axis of the escape pipe (16). The ratchet locks (26,28) are sprung. The longitudinal axis of the ventilator connection pipe (20) is at right angles to the base plate (12). |
