Claims

[Scope of claim for utility model registration] The oil passage connected to the inside of the torque converter is
an inner diameter portion of the sleeve integral with the pump impeller;
The oil passage structure of a torque converter is constituted by an annular gap between the stator shaft and the outer diameter part of the stator shaft for supporting the stator via a one-way clutch, and the sleeve has a flange-shaped part at one end. In the oil passage structure of the torque converter, the flange of the sleeve is integrated with the impeller shell on the outer diameter side of the flange, and the thrust bearing member is in contact with the inner surface of the torque converter of the flange. An oil passage structure for a torque converter, characterized in that a radial groove extending from an inner diameter portion of a sleeve to an outer diameter portion of a flange portion is provided in a portion of the shaped portion facing the thrust bearing member.
