    • 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.
    • 在一种织带缠绕装置中,即使当活塞在活塞移动到最大移动位置时由于反应而在活塞方向上朝向另一侧移动时,钩部的接合表面与主体接合表面接触 使得活塞向运动方向的另一侧的运动受到限制。 因此,防止活塞返回到待机位置,并且防止棘爪返回到锁定位置。 因此,保持锁定环在拉出方向上的旋转的状态。 因此,在活塞从待机位置移动到最大移动位置之后,防止活塞返回待机位置,防止力限制器的负载变化。

    • A webbing take-up device enabling a reduction in size of an overload release mechanism and easy adjustment of an operation torque of the overload release mechanism is provided. In the overload release mechanism of this webbing take-up device, rotary force of a large diameter gear is transmitted to a small diameter gear via plural annular friction springs. The friction springs are disposed between an inner periphery face of a main body portion of the large diameter gear and a tubular portion of the small diameter gear, side by side along an axial direction of the two gears. Consequently, a radial direction enlargement of the large diameter gear and small diameter gear due to space for disposing the friction springs may be restrained. Moreover, the operation torque of the overload release mechanism may be adjusted stepwise by changing the number of the friction springs to be used, in accordance with requirements.
    • 提供一种能够减小过载释放机构的尺寸并且容易调节过载释放机构的操作扭矩的织带卷取装置。 在这种织带卷取装置的过载释放机构中,大直径齿轮的旋转力通过多个环形摩擦弹簧传递到小直径齿轮。 摩擦弹簧沿着两个齿轮的轴向并排设置在大直径齿轮的主体部分的内周面和小直径齿轮的管状部分之间。 因此,可以抑制由于设置摩擦弹簧的空间而引起的大直径齿轮和小直径齿轮的径向扩大。 此外,可以根据要求通过改变要使用的摩擦弹簧的数量来逐步地调节过载释放机构的操作扭矩。
