Abstract
In a fluid transmission system with a lock-up clutch including a plurality of first transmitting claws provided in a clutch piston and inserted between adjacent damper springs, and a plurality of second transmitting claws provided in a turbine impeller and inserted between the adjacent damper springs to oppose the first transmitting claws, the plurality of second transmitting claws are welded to the turbine impeller in a separated and independent manner. Thus, the second transmitting claws can be fabricated with a good yield, and are applicable commonly to various fluid transmission systems of different specifications, leading to a remarkable reduction in cost.
