PROBLEM TO BE SOLVED: To provide a funnel for a vessel capable of adequately preventing smoke pollution to passengers and crew on a deck by providing a means for appropriately maintaining an ascending flow of smoke exhausted from a stack cylinder in navigation. SOLUTION: A louver 7 is provided so as to surround a middle part of the stack cylinder 2 projected and exposed above from a cover 3 on a vessel, and is inclined and installed so that the louver 7 increases its height from a front edge of a stem side to a rear edge on a stern side. A shape of the louver 7 is formed in an arch shape which warps up to both sides. An air flow from a front flows along the louver 7 and maintains the ascending flow of the smoke exhausted from the stack cylinder 2.
