FIELD: construction.
SUBSTANCE: anti-lock device (1) for the rocker arm (2), oscillating relatively to the axle (D1), which position is locked relatively to the plate (3). It contains limiting pin (5) on the plate (3), bistable unit (8) containing rotor (9), that is made synchronous with the rocker arm (2) and lever (11), oscillating relatively another axle (D2) of rotor (9) between two extreme positions of the indexing devices (12) memorizing position of the rocker arm (2), at that trajectory of the lever (11) partially crosses the limiting pin (5) during the rocker arm (2) oscillations; the limiter (15) limiting amplitude in case of impact contains thrust device (16) between the lever (11) and limiting pin (5) interrupting the oscillations at normal arch of the rocker arm, and under pressure changes position of the indexing devices (12) and stops the rocker arm (2) in case of impact.
EFFECT: improved design.
