PROBLEM TO BE SOLVED: To provide a rain gutter water collector which is provided with a drain pipe, and constructed such that a connection ring provided for connecting the water collector to a down pipe, is not easily disconnected from the water collector due to an impact caused by weather and heavy load of snow on a gutter portion. SOLUTION: The rain gutter water collector is formed of a rain gutter receptacle at an upper portion thereof and the drain pipe 12b at a lower portion thereof. The connection ring is interposed between the rain gutter water collector and the down pipe to connect the former to the latter. Herein the rain gutter water collector has an engaging rib 12a in two stages or more which is fitted and connected to an engaging projection 13a formed on an inner surface of the connection ring 13.
