In a mechanism for moving the lower limbs connected to the body (15) of a toy figure (1) to enable the toy figure to walk over a support surface (P) in a similar manner to a human being, each of the limbs includes a thigh-shaped portion (4d, 4s), a lower-leg-shaped portion (5d, 5s) connected to the adjacent end of the thigh-shaped portion by a knee joint (7), and a foot-shaped portion (6d, 6s) connected to the lower-leg-shaped portion (5d, 5s) by an ankle joint (8), and a drive means (32, 34, 35d, 35s, 28d, 28s), housed in a compartment (31) of the body (15) of the toy figure, is connected to the thigh-shaped portion (4d, 4s) in order to impart thereto a pivoting movement in a vertical plane parallel to the direction in which the figure is made to walk, and a rectilinear translational movement in the direction of the longitudinal axis of the thigh-shaped portion between a lower dead-point position and an upper dead-point and vice versa, the movements relating to one limb being out of phase by 180.degree. with the homologous movements of the other limb and the toy figure having means (2, 3) for counterbalancing the reaction torque generated by the drive means during the movement of the thigh-shaped portion (4d, 4s). The mechanism comprises a rod-shaped element (20) extending along the thigh-shaped portion (4d, 4s), the rod-shaped element (20) having one end (21) connected to a point (22) of the lower-leg-shaped portion (5d, 5s) situated towards the hollow (23) of the knee, relative to the axis (10) of the knee joint (7), and the opposite end (24) fitted for sliding freely in a recess (25) with a closed end (25a) formed in the body (15) of the toy figure, as well as a resilient member (26) fitted between a point (27) along the length of the rod-shaped element (20) and a point (16) fixed relative to the thigh-shaped portion (4d, 4s), the resilient member (26) acting on the rod-shaped element (20) to urge the free end (24) thereof towards the end (25a) of the axial recess (25).
