The invention discloses a double-twisted rocker type passive walking device which comprises a leg part composed of two inside legs and two outside legs. The inside legs and the outside legs are connected through a crank. The crank comprises an upper transverse shaft, two middle transverse shafts, two lower transverse shafts and rockers for connecting the transverse shafts. The two inside legs are rotationally arranged on the upper transverse shaft. The two outside legs are rotationally arranged on the lower transverse shafts at the two ends. The inside legs and the outside legs are provided with sliding pipes capable of sliding on the inside legs and the outside legs. The sliding pipes on the two inside legs are connected into a synchronous moving whole through a synchronous shaft. Torsion springs are arranged between the sliding pipes on the inside legs and the sliding pipes of the corresponding outside legs. H-shaped supporting pieces are arranged between the torsion springs and the middle transverse shafts. The middle transverse shafts rotationally penetrate through the upper ends of the H-shaped supporting pieces and the torsion springs penetrate through the lower ends of the H-shaped supporting pieces. The problem that the legs and the feet rub with the ground when swinging is solved, robustness is higher, and the device has wider space in actual application.
