Abstract:
A torque converter comprising:a stator rotatable about an axis, said stator including a stator hub having an end wall extending radially inwardly at an axial end of said stator hub, said end wall being formed with a recessed portion recessed from one axial end face thereof;a thrust bearing including a pair of first and second bearing races opposed to each other and a plurality of rollers disposed between said first and second bearing races, said first bearing race being received by said recessed portion; anda coupling connecting said first bearing race with said stator hub;said coupling including a plurality of projections extending radially outwardly from an outer circumferential surface of said first bearing race and arranged in a circumferentially spaced relation to each other and a plurality of grooves that is engaged with said plurality of projections, said plurality of grooves extending radially inwardly from an outer circumferential surface of said recessed portion that is opposed to said outer circumferential surface of said first bearing race and being arranged in a circumferentially spaced relation to each other, said plurality of projections and said plurality of grooves cooperating to prevent a relative rotation between said first bearing race and said stator.
