The rubber caterpillar comprises several guide and driving force transmission teeth on its inner surface. Each tooth (20) consists of two transverse faces directed transversely to the caterpillar and two lateral faces directed in the longitudinal forward movement of the caterpillar. A plane perpendicular to the caterpillar longitudinal direction cuts a transverse face in three lines. The tooth comprises a front face (21), comprising a cavity (23), and a rear face (22). The front face is composed of two curves (24,25) secant in an intersection point (26). The tangent (27) in this point which cuts the caterpillar internal face, represented by line (28), delimits the front face cavity. The line (29) which represents a plane perpendicular to the caterpillar longitudinal direction cuts the front face in three points (30,31,32).
