Abstract: A webbing take-up device is obtained that is capable of reducing the load on a reduction balance spring without using special components, and without performing special processing on a spiral direction inside end of the reduction balance spring. When the reduction balance spring rotates in a take-up direction as winding of the reduction balance spring loosens, an inside engagement portion turns in the take-up direction inside an engagement groove. Accordingly, a load absorption portion which is further to a main body portion side of the reduction balance spring than the inside engagement portion curves into a concave shape that is open towards a pull-out direction as the load absorption portion stands up. In this state, when further load in the take-up direction acts on the reduction balance spring, this load is absorbed by the load absorption portion undergoing resilient deformation so as to curve further.

A spring clutch transfers rotation of the take-up shaft in a seatbelt drawing-out direction to a ring. A secondary spiral spring is capable of generating rotational biasing force on the take-up shaft in a direction opposite that of the primary spiral spring.

Abstract: A webbing take-up device which, when a webbing belt is pulled out, can reduce urging force applied in a direction of taking up the webbing belt. When a spiral spring 48 rotates an adapter 44 with a plunger 70 engages a ratchet wheel 52, a torsion coil spring 56 is wound tighter on the adapter 44. A resultant force of frictional force at this time and urging force of the torsion coil spring 60 which is fit tightly to adapters 30, 44 is greater than urging force of the spiral spring 48. Thus, the torsion coil spring 60 is slack, and the adapter 30 rotates relatively to the adapter 44. In this way, until the torsion coil spring 60 is fit tightly to the adapters 30, 44, even if the webbing belt 26 is pulled out, urging force of the spiral spring 48 is not applied to a spool 20.
