PROBLEM TO BE SOLVED: To provide an opening and closing device with a braking device capable of eliminating the interference between a roller for opening, closing, and moving an opening and closing body along a guide member and a rack constituent body for rotating a pinion gear of the rotary braking device. SOLUTION: A door body 1 being the opening and closing body of a sliding door device is of up suspension type for putting a roller 32 on a guide rail 30 being the guide member connected with an upper frame member 10 being an immobile member and suspending from the guide rail 30. The rotary braking device 40 provided with the pinion gear 41 meshing with the rack constituent body 50 attached to the upper frame member 10 through a holding member 51 when the door body 1 is guided onto a fully closing position side by the guide rail 30 and moves is attached to the door body 1. An arrangement position of the roller 32 and an arrangement position of the rack constituent body 50 are deviated by distance A in the axial direction of rotary central shafts 37, 42 of the roller 32 and the pinion gear 41.
