  • Patent number: 7322454
    Abstract: In a fluid transmitting device, a plurality of first power transmission claws are inserted between adjacent ones of damper springs and secure to a clutch piston; and a plurality of second power transmission claws are inserted between adjacent ones of the damper springs so as to face the first power transmission claws, and has support portions which are connected to an outer peripheral surface of a shell of a turbine impeller via a weld formed by laser beams. The weld is formed into a linear shape extending along a circumferential direction of the shell so that the weld is melt by the laser beams to extend from an outer surface of the support portion to an inner peripheral surface of the shell. Thus, it is possible to easily perform welding between the support portions of the second power transmission claws and the shell of the turbine impeller, and to easily perform a visual inspection as to whether the welding condition is good or not.
