Claims

[Claims for Utility Model Registration] 1. A fixing structure for the thrust needle bearing in a torque converter in which the thrust needle bearing is disposed between the inner surface of a cover shell that is integrally coupled with a pump impeller and the turbine hub of a turbine runner. The thrust needle bearing is a one-piece type in which a retainer that holds the needle and races placed on both sides of the retainer are assembled so that they do not separate, and the race on the cover shell side matches the outer diameter of the retainer. The large diameter part of the race on the cover shell side is provided with a rotation prevention groove, and the rotation prevention pawl and the cover can be fitted into this rotation prevention groove. A bearing fixing member having an axial fixing pawl located at a position corresponding to the portion of the large diameter portion of the race on the shell side that is not provided with the anti-rotation groove is fixed to the cover shell. The anti-rotation pawl fits into the anti-rotation groove of the race on the cover shell side, and the axial fixing pawl of the bearing fixing member sandwiches the large diameter portion of the race on the cover shell side between this and the cover shell. A thrust needle bearing fixed structure for torque converters. 2. In the thrust needle bearing fixing structure of the torque converter, in which the thrust needle bearing is disposed between the inner surface of the cover shell that is integrally coupled with the pump impeller and the turbine hub of the turbine runner, the thrust needle bearing is The retainer that holds the retainer and the races placed on both sides of the retainer are integrated so that they do not separate, and have a small diameter part that is smaller than the inner diameter of the race retainer on the cover shell side. A rotation prevention groove is provided in the small diameter portion of the race on the cover shell side, and a rotation prevention pawl that can fit into this rotation prevention groove and a rotation prevention groove in the small diameter portion of the race on the cover shell side are provided. A bearing fixing member having an axial fixing pawl disposed at a position corresponding to the portion where the bearing fixing member is not provided is fixed to the cover shell, and the anti-rotation pawl of the bearing fixing member prevents rotation of the race on the cover shell side. A thrust needle bearing fixing structure for a torque converter, characterized in that an axial fixing pawl part of a bearing fixing member fits into a groove, and a small diameter part of a race on the cover shell side is sandwiched between this and a cover shell. .
