Claims

[Scope of utility model registration request]

A pump impeller and a turbine runner are arranged to face each other with the stator wheel in between, the pump impeller is connected to the crankshaft via a converter cover, the turbine runner is connected to an input shaft, and the stator wheel is connected to the crankshaft via a one-way clutch. A lock-up piston that rotates together with the turbine runner and has a clutch facing fixed to its peripheral edge is fitted to the input shaft so as to be slidable in the axial direction, and the converter cover and lock-up piston form a lock-up chamber. define,
In the torque converter with a lock-up, which causes hydraulic oil to flow through the lock-up chamber to provide a non-lock-up state, and which cuts off the supply of hydraulic oil to provide a lock-up state, there is provided a substantially shaft on the wall of the lock-up chamber that changes the flow direction of the hydraulic oil. 1. A torque converter with a lockup, characterized in that a plurality of fins are provided inside the inclined surface and extend in a substantially radial direction.
