FLUID COUPLING AND STARTING DEVICE

WIPO Patent Application WO/2010/038548

A1

A fluid coupling is provided with a pump impeller disposed in a torque transmission path and a turbine runner disposed downstream from the pump impeller in the torque transmission path.  The pump impeller comprises multiple pump blades (47) arranged at even intervals circumferentially about a rotational axis line (S).  The turbine runner comprises multiple turbine blades (49) arranged at even intervals circumferentially about the rotation axis line (S).  In each of the turbine blades (49), a first turbine-side protrusion (54) located radially on the outside is formed in such a manner that the front end thereof is located downstream from the base end thereof in a rotational direction (R), and a second turbine-side protrusion (55) located radially on the inside is formed in such a manner that the front end thereof is located upstream from the base end thereof in the rotational direction (R).
