A reduction sliding spring is formed in a curved shape, such that the radius of curvature becomes gradually larger in a predetermined ratio toward a longitudinal central portion from both longitudinal ends in a state where the reduction sliding spring has not been elastically deformed in a circular shape. The amount of elastic deformation accompanying a minute change in a position from the longitudinal central portion to both longitudinal ends becomes approximately equal in a state where the reduction sliding spring has been elastically deformed in the circular shape.

The adapter having received a pressing force generated by this pressing at the hole-section-side inclined-surfaces has rotated in the pull-out direction, and then the phases of the fitting-hole section and the fitting-shaft section have aligned about the central-axis line of the spool-body, each shaft-section-side protrusion intrudes into a gap between the hole-section-side protrusions adjacent to each other, and the fitting-shaft section fits into the fitting-hole section. | 12-22-2011 |

When a ring inertially rotates in a retraction direction together with a ratchet gear, a ring-side pressing portion of a load receiving portion accommodating portion formed in the ring presses a spring-side load receiving portion of a clutch spring in the retraction direction. Due to this, the clutch spring is loosened, whereby the ring can easily inertially rotate in the retraction direction together with the ratchet gear, and the load acting on a reducing balance spring can be alleviated. | 04-11-2013 |
20140084098 | WEBBING TAKE-UP DEVICE - 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. | 03-27-2014 |
