摘要： In the present pretensioner, press contact portions are formed further to a side of an open end of a packing housing section than central portions of opposing faces along a depth direction of the packing housing section. Accordingly, when a packing is being fitted into the packing housing section, no great resistance is imparted to a curved face side of the packing from a press contact wall of a housing section body and the opposing face, and the packing is fitted comparatively smoothly therein. Consequently, even when fitting the packing into the packing housing section, a packing main body is largely resilient-deformed, such that a large collapse in a through hole can be prevented, and the sealing ability of the seal due to deformation of the packing main body can be effectively enhanced.

摘要翻译： 在本发明的预张紧器中，沿着包装容纳部的深度方向，与接合面的中央部分相比，在接合部的开口端的另一侧形成有压接部。 因此，当将填料装配到填料容纳部中时，不会从容纳部主体的压力接触壁和相对面向衬垫的曲面侧施加大的阻力，并且衬垫相对平滑地配合 。 因此，即使将密封件装配到包装容纳部中，包装主体大部分弹性变形，能够防止通孔中的大的塌陷，并且密封件由于包装主体的变形而产生的密封性 身体可以有效地增强。

摘要： In the pretensioner, a guiding wall is provided in a generator-side passing portion of a gas passing portion, and an inner portion of the generator-side passing portion at a portion where the guard wall is set is located to a base end rather than a tip end of a wire protective cylinder. Further, a gas generator mounting hole and the generator-side passing portion is inclined to be directed the base end of the wire protective cylinder. For this reason, gas that is jetted from a gas generator is blown to the base end of the wire protective cylinder or a surrounding portion thereof. As a result, even though the thickness of the wire protective cylinder is not set to be large, it can be against pressure of the blown gas.

摘要： In a webbing winding device, even when a piston moves toward the other side in a movement direction due to a reaction when the piston moves to a maximum movement position, an engagement surface of a hook portion comes into contact with a subject engagement surface of a subject engagement portion, so that the movement of the piston toward the other side in the movement direction is restricted. Accordingly, the piston is prevented from returning to a standby position, and a pawl is prevented from returning to a lock position. For this reason, a state where a rotation of a locking ring in the pull-out direction is maintained. Accordingly, after the piston moves from the standby position to the maximum movement position, the piston is prevented from returning to the standby position, and the force limiter load is prevented from being changed.

摘要： A webbing take-up device capable of smoothly releasing rotation locking while also stabilizing a load support direction during rotation locking. A pawl is equipped with a flat plane shaped load receiving face. The pawl is normally retained in a load receiving position but is rotationally moved when imparted with drive force of a drive mechanism section. The lock ring is equipped with a protrusion portion set with a lower rigidity than the rigidity of the pawl. The lock ring is not capable of rotating by the protrusion portion being supported by the load receiving face of the pawl, and rotation is permitted by moving the load receiving face away from the protrusion portion with rotational movement of the pawl.

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： 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.
