Structure for preventing shaft of constant velocity joint from coming off

摘要

The present invention presents a structure for preventing a shaft (6) of constant velocity joint (1) from coming off which allows changing design of connection between the shaft and an inner joint member (3) to a type for disassembly or anti-disassembly. The anti-disassembly type is realized in such a manner that a wall at an opposite side to a shaft pulling out direction of a retaining ring groove (13) of the shaft is used as a contacting part to a retaining ring (14), wherein at least two points are formed on the contacting part, one of which is on a perpendicular surface and the other is a corner of the contacting part, these two points are contacted with an inner surface of the retaining ring thereby provides the anti-disassembly type for preventing the ring from being contracted in a radial direction.
