Further, the washer 2g line width (thickness) is set to be larger than the width of the annular groove 2a2, which is not fitted in the gasket 2g the annular groove 2a2. Card of the annular groove 2a2 of the retaining ring 2h, i.e., fitting the E-ring or C-ring will indeed be carried out, e.g., in the mounting portion of the mounting operation is identified difficulties, 2b of the locking ring the annular groove 2a2 of the fitting can be reliably performed. Thus, the assembly of the gear unit 2a, 2b of the base part easily and reliably be performed in 2 of the driven gear, without having to check the locking -11-- (9) (9) 200 417 700 of the annular ring 2h groove 2a: fitting state, or reduced, so the time for which the installation will be greatly shortened, and the workability was put Bureau use of the mounting significantly. Instead of the embodiment of various forms can be considered. Although in the foregoing embodiment, the mounting system configured as the driven gear of the engine shaft equalizer, of course, not limited thereto, this mounting structure, based in the scope without departing from the spirit of the present invention, will be installed in various parts of It is applicable. Although in the foregoing embodiment, as allowed between the base portion and the gear portion of the driven gear to rotate relative quantification of the elastic member, the elastic member is used in combination intervention of a spring coil springs and elastic members such as rubber, but ' the resilient member may be formed by a coil spring, and may be made of an elastic rubber, and even more and may be appropriately selected other springs or elastomer is only only.
