    • In a fluid transmitting device with a lock-up clutch, each second transmitting claw is formed of: a base portion having a long side arranged in a peripheral direction of a turbine impeller and a short side arranged axially of the turbine impeller; and a claw portion protruding from an intermediate portion of one of long-side portions of the base portion and being inserted between adjacent damper springs, and each short-side portion of the base portion is fixed to the turbine impeller through a weld. A long-side portion of the base portion not welded to the turbine impeller includes a cutout, facilitating bend of the long-side portion when transmitting torque through the second transmitting claw, at opposite sides of the claw portion. This improves engine output performance by relaxing stress concentration at spots where the second claws are welded to a turbine impeller without increasing the thicknesses of the claws.
    • 在具有锁止离合器的液体传递装置中,每个第二传递爪由以下部分形成:具有沿涡轮机叶轮的周向布置的长边的基部和沿涡轮叶轮的轴向布置的短边; 以及爪部,其从所述基部的长边部的中间部突出并且插入在相邻的阻尼弹簧之间,并且所述基部的每个短边部通过焊接固定到所述涡轮叶轮。 未被焊接到涡轮叶轮的基部的长边部分包括切口,在爪部的相对侧处有助于在通过第二传递爪传递扭矩时长边部弯曲。 这通过在不增加爪的厚度的情况下将第二爪焊接到涡轮叶轮的点处的应力集中放松来提高发动机输出性能。
