PURPOSE:To improve safety against a strong wind in an evacuation perpendicular chute at the time of a vessel accident by making tubular a lengthy chute main body which has unified meandering bag-shaped slide-down passage formations, and connecting to this a lengthy tubular approach passage main body which has a deceleration passage and an escape opening. CONSTITUTION:When a first evacuee slides down along a meandering slide-down passage 12 and reaches an approach passage 8, he is caught at the funnel-shaped deceleration passage 81 of the approach passage 8. And the evacuee slides down more or less in a twisted way along the deceleration passage 81, and falls slidingly into the next deceleration passage 81 through a small diameter exit 812, and reaches a platform 2. And he gets out of an escape window 82 and prevents swinging by fixing the approach passage 8 to the platform 2. At this time, the evacuee falls slidingly along the fitting line of a large inclination angle theta1, but since the escape window 82 opens at the lower part of the large inclination angle theta1, he falls slidingly in a direction in which the escape window 82 is not open, and has no fear of jumping out of the escape window 82. Safety can thus be secured against a strong wind.
