摘要： To simplify the structure of a webbing retractor, at a second locking mechanism 44 of the webbing retractor, when a gas generator is not operated, a cam engages with an outer peripheral groove of a lock ring, and a limit load by a torsion shaft is made to be a high load. On the other hand, when the gas generator is operated, the cam is moved apart from the outer peripheral groove of the lock ring, and the limit load by the torsion shaft is made to be a low load. Because only the cam is interposed between the lock ring and a piston which is driven by the gas generator, the number of parts of the second locking mechanism can be reduced, and the structure of the second locking mechanism can be made simple.

摘要： In a webbing winding device, a sub-torsion shaft is inserted from one side in the axial direction of a spool into the spool when assembling the sub-torsion shaft to the spool. Subsequently, by the sub-torsion shaft rotating in the winding direction, movement of the sub-torsion shaft with respect to the spool in the winding direction and in one side in the axial direction is inhibited. Subsequently, by a stopper being fitted from one side in the axial direction into insertion groove portions, movement of the sub-torsion shaft with respect to the spool in the pull out direction is inhibited. Accordingly, since the direction in which the sub-torsion shaft is assembled to the spool becomes only a direction parallel to the axial direction of the spool, the assembility of the sub-torsion shaft with respect to the spool may be improved.

摘要翻译： 在卷绕卷绕装置中，当将副扭转轴组装到卷轴时，副扭转轴从卷轴的轴向方向的一侧插入卷轴中。 随后，通过副卷轴在卷绕方向上旋转，副扭转轴相对于卷轴在卷绕方向上的移动和轴向一侧的运动被抑制。 随后，通过从轴向一侧嵌入插入槽部的止动件，抑制副扭转轴相对于卷轴的拉出方向的移动。 因此，由于副扭转轴组装到卷轴上的方向仅仅是与卷轴的轴向平行的方向，所以可以提高副扭转轴相对于卷轴的组装性。

摘要： Plural door portions are formed by sectioning the gas blowing section of the gas generator with slits. In a state in which gas has been generated by the gas generator, the plural door portions part at the slits and open towards the outside of the casing body. A gas flow path section is connected to a peripheral wall section configuring an deployment space permitting opening of the door portions. The gas flow path section is provided with an upstream portion which is in communication with the deployment space and formed along a direction orthogonal to the direction of gas blowing from the gas blowing section, and an opening portion provided at the gas inflow side, which is set so as to communicate with a space which is between adjacent door portions when the door portions 56 are in a opened state.

摘要： 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.

摘要： A webbing take-up device that is both capable of promoting reductions in size and weight and capable of excellently maintaining coupling strength between a pawl member and a ring portion. A clutch plate and a lock ring of this webbing take-up device are coupled by plural teeth provided at the clutch plate meshing with plural teeth provided at the lock ring. This lock ring is specified to have a lower material strength than the clutch plate. A tooth height H2 of the plural teeth of the lock ring is specified to be lower than a tooth height of the plural teeth of the clutch plate. Thus, when the lock ring and the clutch plate mesh, tooth tips of the plural teeth of the clutch plate come into contact with tooth bottoms of the plural teeth of the lock ring.

摘要： A coil spring is provided in a compressed state between a coupling wall section provided at a clutch guide and an inner-side locking section. The clutch guide is provided with a support section which supports one axial-direction end section of the coil spring from a side opposite to the clutch cover in an axial direction of the clutch guide. The clutch cover is provided with a leading-end protruding section which is projected with respect to the inner-side locking section so as to be inserted in the other axial-direction end section of the coil spring. The leading-end protruding section is inclined, with respect to a direction orthogonal to an axial direction of the clutch cover, toward a support section side, so that the coil spring is curved so as to be convex to the support section side.
