Abstract
A front cover 5 of a converter cover 4 is formed with a punched hole 12, a thrust bearing 13 having the same outer shape as that of the punched hole 12 is fitted to the punched hole 12, a bearing housing 14 is fitted to the outside, thereby tightly closing the converter cover 4 to support the thrust bearing 13. A thrust applied from a turbine hub 9 to the thrust bearing 13 is received by a flange 14b of the bearing housing 14.
