Abstract: A retractable massage roller includes two end caps and multiple ring-shaped unit bodies arranged along an axial direction, the two end caps being respectively connected to outermost two unit bodies of the multiple unit bodies. Every three adjacent unit bodies are connected through multiple connecting rods, the multiple connecting rods are independent of the three adjacent unit bodies, each connecting rods is movably disposed on and passes through the three adjacent unit bodies and the three adjacent unit bodies are capable of sliding on the multiple connecting rods. Outermost two unit bodies of the three adjacent unit bodies are respectively positionally-limited at two ends of each connecting rod through first limiting mechanisms, when the retractable massage roller is in a stretched state. Every two adjacent unit bodies of the multiple unit bodies are positionally-limited through second limiting mechanisms, when the retractable massage roller is in a contracted state.
