ABSTRACT OF THE DISCLOSURE An improved vertical elongated chute usable fox allow- ing a person who has to leave a ship to descend on the sea surface in the event of an occurrence of emergency. The vertically extending main body is made of a base cloth of which both longitudinally extending side edges are jointed to one another to build a tubular zigzag slip down passage. A zigzag slip down passage cloth having a plurality of bent parts is fixedly secured to the base cloth. An inclined slip way is jointed to the lower end of the main body so that the person who has desdended through the zigzag slip down passage lands on the platform by way of the inclined slip way. An expansible cloth of which expansibility is deter- mined in the range of 200 to 250 % as seen in the longitu- dinal direction as well as in the peripheral direction of the main body is fixedly secured to each of the bent parts on the zigzag slip down passage cloth. When dead weight of the descending person is exerted on the expansible cloth, the zigzag slip down passage is caused to expand whereby he descends through the zigzag slip down passage smoothly without any occurrence of stoppage at the bent parts on the zigzag slip down passage cloth. Thus, he can land on the platform serving as a lifeboat quickly and safely.
