The creation is a roller structure, which includes: a main body, an inner lining, and two grips, and the main body has a rigid hollow pipe body, a central hollow portion, and two sides with openings； and the inner lining is a hollow column shape. The body is assembled in the hollow part of the main body, with a hollow part in the center, and blocking parts on the two sides of the hollow part. The grips are respectively set in the hollow part of the inner lining, with a ring seat, a handle, and the ring. The diameter of the seat is slightly smaller than the diameter of the hollow portion, and it has a ring surface and two sides, and a retaining edge on one side can be abutted against the abutment portion； and one end of the handle is connected to the side of the ring seat, and the handle of the handle can be retracted. It fits into the main body or protrudes out of the main body； this creation can have better use and storage convenience.本創作係一種滾筒結構，包括：一主體、一內襯、二握把，並該主體具一硬質中空管體，中央具透空部，二側具開口；又該內襯為中空柱狀體，組設於主體之透空部內，中央具中空部，又於中空部二側分別設置擋靠部；又該握把分別組設於內襯之中空部內，具一環座、一把手，該環座直徑略小於中空部直徑，具環面及二側面，又於一側面設置可與擋靠部抵靠之擋緣；又該把手一端與環座之側面連結，並使握把之把手可收合於主體內或伸出主體外；藉此本創作可具較佳使用及收納便利性。
