ABSTRACT:
To provide a stator in which a stator and an impeller or a turbine are brought into direct contact with each other to thereby dispense with a thrust bearing, and in which a frictional wear in the contact portion is suppressed to a small extent to thereby prolong a service life of a torque convertor, a stator 7 is provided with a thrust receiving portion 7c for a torque convertor with an impeller and a turbine facing each other. The thrust receiving portion 7c is provided in an inner circumferential portion of the stator, and brought into contact with the impeller so that an axial movement of the thrust receiving portion 7c is limited. Oil grooves 7d for recirculating and holding working oil are formed in a contact surface of the thrust receiving portion 7c.
