Fluid transmission device with lock-up clutch
In a fluid transmitting device, a plurality of first power transmission claws 33 are inserted between adjacent damper springs 32 and secure to a clutch piston 25; and a plurality of second power transmission claws 34 are inserted between adjacent damper springs 32 so as to face the first power trans...

| description | In a fluid transmitting device, a plurality of first power transmission claws 33 are inserted between adjacent damper springs 32 and secure to a clutch piston 25; and a plurality of second power transmission claws 34 are inserted between adjacent damper springs 32 so as to face the first power transmission claws 33, and has support portions 34b which are connected to an outer peripheral surface of a shell 3s of a turbine impeller via a weld 40 formed by laser beams. The weld 40 is formed into a linear shape extending along a circumferential direction of the shell 3s so that the weld 40 is melted by the laser beams to extend from an outer surface of the support portion 34b to an inner peripheral surface of the shell 3s. Thus, it is possible to easily perform welding between the support portions 34b of the second power transmission claws 34 and the shell 3s of the turbine impeller 3, and to easily perform a visual inspection as to whether the welding condition is good or not. |
