<P>PROBLEM TO BE SOLVED: To provide a structure for connecting a universal joint york and a shaft, which prevents incomplete serration fitting between the universal joint york and the shaft from being fastened and fixed, and facilitates serration fitting. <P>SOLUTION: The structure for connecting a universal joint york and a shaft includes: the universal joint york which has female serration formed on the inner peripheral surface and expands and contracts the female serration inner diameter by forming a slit over the female serration from the outer circumferential surface; and the shaft in which the male serration fitted to the female serration is formed on one side end part. One side of a valley-plugged part or a missing tooth part is formed on the outer circumferential surface of the male serration, and the other side of the valley-plugged part or the missing tooth part is formed on the inner peripheral surface of the female serration. A small-diameter cylindrical part is formed on the shaft end side from the male serration part formed on the end part of the shaft. <P>COPYRIGHT: (C)2012,JPO&INPIT |
