Abstract
A seat belt retractor includes a cylindrical member, a torsionally deformable shaft arranged inside the cylindrical member and having one end side connected to the cylindrical member, a plate mounting member arranged in the cylindrical member and disposed on an outer periphery of the shaft, a locking mechanism for preventing a rotation of the plate mounting member, and a plate member having one end portion fixed to the plate mounting member and the other end portion engaging an inner periphery of the cylindrical member. The plate member is plastically deformable so that the plate member is wound onto the plate mounting member. The plate mounting member includes a first reducing radius portion having a radius gradually decreasing toward a downstream in a winding direction, and a second reducing radius portion located on the downstream side and having a radius reducing rate greater than that of the first reducing radius portion.
