The invention discloses a magneto-rheological buffer capable of reducing an impact peak value and provided with shunting pressure relief holes in an inner cylinder. The magneto-rheological buffer comprises the inner cylinder with holes, an outer cylinder and a piston. The inner cylinder with the hole is arranged in the outer cylinder, the piston is arranged in the inner cylinder with the hole, and the piston is matched with the inner cylinder with the hole through a sealing structure and can slide along the inner wall of the inner cylinder with the hole; the inner cylinder with holes and the outer cylinder are filled with magnetorheological fluid; a plurality of shunting pressure relief holes are formed in the body of the perforated inner cylinder, and a plurality of flowing holes are formed in the end part of the perforated inner cylinder; when the piston moves in the inner cylinder with the hole, the magnetorheological fluid in the inner cylinder with the hole is pushed by the piston, flows into the gap bet
