The utility model provides an overrunning clutch which comprises an outer rotor, an inner ratchet wheel, at least one groove, a stop block and at least one magnet block, wherein the inner ratchet can coaxially rotate with the outer rotor; the groove is formed on the inner circumferential surface of the outer rotor and faces towards a central opening of the inner circumferential surface of the outer rotor; the stop block which is contained in the groove has magnetism and can rotate in the groove; the magnet block is adjacent to the groove, wherein the magnet block and a magnetic pole adjacent to the stop block have the same polarity; thus, the problem that a cylindrical roller type overrunning clutch and a wedge type overrunning clutch transfer the torque moment due to the friction is solved by depending on the stop force generated by the mutual compensation between the stop block and the inner ratchet wheel, the transferring effect of the torque moment is ensured, and the service life of the overrunning clutc
