The invention relates to a door body of a roller washing machine and the roller washing machine. The door body comprises a inner frame, a glass basin, a middle frame, a window screen and an outer frame which are disposed successively from the inner side of the door body to the outer side of the door body, wherein the middle frame is connected to the inner frame by welding; the glass basin is clamped between the inner frame and the middle frame; the window screen is clamped in the middle frame; the outer frame is in a clamped connection with the middle frame and/or the inner frame; clamping structures which are in a clamped connection with the middle frame are disposed on peripheries of the surface of the window screen facing the middle frame; and a groove-shaped gap is formed between the adjacent clamping structures. According to the invention, groove-shaped structures are disposed between the clamping structures of the window screen; the clamping structures stretch into space between the outer frame and the middle frame and are in a clamped connection with the middle frame; and edges of the groove-shaped gaps support the outer frame. In this way, a supporting face between the window screen and the outer frame is reduced; and noise which is generated from friction between the window screen and the outer frame when the window screen is pressed can be avoided.
