A stator support device for a torque converter having a stator wheel and a non-rotating member has a one-way clutch and a bearing race. The one-way clutch includes an outer race disposed along the inner periphery of the stator wheel, an inner race connected to the outer periphery of the non-rotating member to prevent rotation of the inner race relative to the non-rotating member, and an end bearing provided between the outer race and the inner race. The bearing race is disposed at a side face of the outer race. The bearing race is supported so as to be rotatable in the circumferential direction. A gap is formed between the bearing race and the stator wheel.

What is claimed is: 1. A stator support device for a torque converter having a stator wheel and a non-rotating member, the stator support device comprising: a one-way clutch that includes an outer race, disposed along the inner periphery of the stator wheel, an inner race, connected to the outer periphery of the non-rotating member, that prevents rotation of the inner race relative to the non-rotating member, and an end bearing, provided between the outer race and the inner race, wherein the outer race has a plurality of outer race oil passage grooves formed along the circumferential direction therein; and a bearing race disposed at a side face of the outer race, wherein the bearing race is supported so as to be rotatable in the circumferential direction, and wherein a gap is formed between the bearing race and the stator wheel in the axial direction, a length of the gap being substantially equal to a depth of at least one of the outer race oil passage grooves. 2. The stator support device according to claim 1, wherein the inner peripheral part of the stator wheel and an outer peripheral part of the outer race are press fitted together; wherein the outer race has a step part formed in the outer peripheral part thereof; wherein the stator wheel has a protruding part formed on the inner peripheral surface thereof, the protruding part facing inwardly in the radial direction, and wherein a side wall of the step part and a side wall of the protruding part are in mutual contact. 3. The stator support device according to claim 1, wherein the end bearing has a lubricating oil hole formed therein, the bearing race has a plurality of bearing oil passage holes formed along the circumferential direction of a side face thereof, the bearing oil passage holes communicate with the lubricating oil hole, the bearing race further has a plurality of bearing oil passage grooves formed in the outer peripheral part thereof, the outer race oil passage grooves communicate with the bearing oil passage holes, and wherein lubricating oil is supplied to the bearing oil passage grooves through the outer race oil passage grooves that communicate with at least one of the bearing oil passage holes. 4. The stator support device according to claim 3, wherein the bearing oil passage holes are formed with a uniform angular spacing therebetween. 5. The stator support device according to claim 3, wherein the circumferential direction widths of the bearing oil passage holes are greater at the outer peripheral side than at the inner peripheral side. 6. The stator support device according to claim 3, wherein the bearing oil passage grooves are formed with a uniform angular spacing therebetween. 7. The stator support device according to claim 1, wherein the bearing race is prevented from moving in the axial direction relative to the stator wheel by coming into contact with a snap ring press fit into the inner peripheral surface of the stator wheel. 8. The stator support device according to claim 1, wherein the bearing race comprises bearing steel.
