PROBLEM TO BE SOLVED: To enhance general versatility for easily, manually rolling a gutter and for easy use in any place with a simple structure. SOLUTION: This inverting device K inverts a gutter S having a bottom plate 1 and a pair of side walls 2 and open ends 3 at the both ends. The device K is provided with a base member 10 having outer edge parts 11 facing the inner surface of the bottom wall 1 and the inner surfaces of the side walls 2 of the gutter S and an exposed surface 12 outwardly exposed from the open ends 3 of the gutter S and formed in a frame shape to engage with the open ends 3; and engaging parts 20 projected from the exposed surface 12 of the base member 10 and engaged with a bar material B. The bar material B rolls the gutter S as well as the base member 10. Each engaging part 20 is consisted to have a through hole 21 for penetrating through the bar material B in the direction generally intersecting the longitudinal axis of the gutter S. Two sets (X, Y) of a pair of engaging parts S are provided at given intervals in the direction having different penetrating angles of the bar material B. Each outer edge part 11 of the base member 10 is provided with rubber elastically coming into contact with the inner surface of the gutter S.
