PROBLEM TO BE SOLVED: To provide a drain ditch structure which can eliminate the state of having a gap between a ditch cover and a receiving frame clogged with refuse, pebbles and the like and having them attached fixedly, and which enables a water channel to be simply cleaned with a broom and the like. SOLUTION: A drain ditch structure includes a receiving frame 2 which is buried in a road surface pavement 1, and a ditch cover 3 which covers an upper opening of the receiving frame 2. The receiving frame 2 comprises a bottom member 20, a pair of right and left side walls 21 and 21, and each pair of right and left supports 22 which are intermittently fixed along longitudinal directions of opposed surfaces of both the side walls 21 and which support the ditch cover 3. The support 22 comprises a base wall 28 which is fixed to the side wall 21, a first support plate 29 which is protruded toward the center of a ditch from an upper edge of the base wall 28 and which supports the ditch cover 3, and a second support plate 30 which is protruded toward the center of the ditch from a lower edge of the base wall 28.
