  • Patent number: 10794478
    Abstract: A washer having such a thickness t that a value (L3?(L1+L2+t)) obtained by subtracting the sum of a first distance L1 in an axial direction between a leading end face of a friction member and a face of a lockup piston, a second distance L2 in the axial direction between a shell-side abutting face of a pump shell and a face of an outside extended portion of an output hub, and the thickness t in the axial direction of the washer, from a third distance L3 in the axial direction between an opposed face of a front cover and a cover-side abutting face of a tubular portion, is in a predetermined range larger than zero, is selected and placed between the lockup piston and the outside extended portion of the output hub.

  • Patent number: 7762065
    Abstract: 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.
