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.

Abstract: A webbing retractor that can alleviate the load on a reducing balance spring without increasing cost and weight is obtained. 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.

Abstract: It is provided a webbing winding device with good assembly characteristics of components in a second lock unit. In the webbing winding device, due to a leading end of a spring tab of a guide plate interacting with ratchet teeth of an internal ratchet and a second lock base rotating in the pull-out direction in this state, relative rotation occurs between the guide plate and the second lock base, and a second lock pawl is meshed with the ratchet teeth of the internal ratchet. Since this configuration is not a configuration in which relative rotation between the guide plate and a second lock base is induced by bias force of bias means, such as a compression coil spring or the like, there is no bias force received in the rotational circumferential direction when the guide plate and the second lock base are being assembled, resulting in easy assembly.

Abstract: An operating load of an overload releasing mechanism is made to be high by a simple method. In a webbing retractor, spring claws engage with recesses of a rotor, and a gear wheel and the rotor are connected. When relative rotational force is applied between the rotor and the gear wheel, the spring claws elastically deform and engagement thereof with the recesses is released. Due thereto, connection of the rotor and the gear wheel is released, and the overload releasing mechanism is operated. Here, urging members urge the spring claws toward a side of engaging with the recesses. Due thereto, the operating load of the overload releasing mechanism can be made to be high by a simple method of merely adding the urging members.

Abstract: The present invention is directed to a modular roll-up partition assembly, such as a rolling protective shutter, implementing an improved tension adjustment mechanism for torsion springs used in roll-up partition assemblies. In one embodiment, the roll-up partition assembly of the present invention includes a tension adjustment mechanism to adjust the tension of a torsion spring connected between a support rod and the partition support member. The tension adjustment mechanism rotates the support rod to move the end of the torsion spring connected to the rod relative to the end of the torsion spring connected to the partition support member. Unlike previous roll-up partition assemblies which permitted adjustment of the torsion spring tension only in increments of a full rotation of the support member, the tension adjustment mechanism facilitates fine adjustment of the torsion spring in increments of less than a full rotation of the partition support member.
