A torque converter includes: a impeller having an outer shell, an inner core, and at least one pump blade provided between the outer shell and the inner core; a turbine having at least one turbine blade; and a stator capable of establishing a fluid circulation between the impeller and the turbine. An exit angle of the at least one pump blade is greater than &#x2212;90 degrees up to &#x2212;68 degrees at the most, beginning from a first point, at which the at least one pump blade is in contact with the outer shell, to a second point, at which the at least one pump blade is in contact with the inner core.

Torque converter

A torque converterwith a lock-up deviceis provided to improve damping performance while suppressing an increase in the axial dimension. A torusof the torque converterincludes an impellera turbineand statorThe torushas a shape such that a radial direction dimension is longer than an axial dimension thereof, and a longitudinal axis tis inclined away from a straight line P perpendicular to a rotational axis such that a radially outer portion of the longitudinal axis tis closer toward the engine than a radially inner portion thereof. The torsion springsare located adjacent on the front cover side of a radially inner portion of the torus
