The invention relates to the technical field of safety belts, in particular to a retractor clutch of a motor pre-tightening driving type safety belt. The retractor clutch comprises a clutch ratchet wheel, a friction drive constraint disc, a clutch pawl, a worm wheel seat and a transmission base. Compared with the prior art, the retractor clutch structure of the motor pre-tightening driving type safety belt is designed, due to the fact that only five parts are arranged, the structure is simple, assembling is convenient, and the cost is lowered. According to the retractor clutch, the functions of friction force driving, clutch pawl motion guiding and constraining are integrated, the functions of friction force generating and axial fixing can be achieved at the same time through an opening elastic external expansion hook, different numbers of clutch claws are matched to meet the power transmission requirements of different powers of the motor pre-tightening driving type safety belt, hence, the universality of the motor pre-tightening driving type safety belt is improved, and the intelligence and the active protecting effect of the safety belt are improved as well.
