摘要： The present invention provides a constant velocity universal joint having a recess-projection engagement configuration in which backlash at a shaft connecting region does not easily occur, and an inner joint component and a shaft can be firmly connected. In the constant velocity universal joint of the present invention, the inner joint component and the shaft 5 fitted into an axis hole 22 of the inner joint component are connected by the recess-projection engagement configuration. Engagement contacting regions 38 of projections 35 and recesses 36 corresponding thereto are in close contact over the whole region.

摘要： PROBLEM TO BE SOLVED: To provide a bearing device for a wheel capable of restraining looseness in the circumferential direction, superior in connection workability of a hub wheel and an outside joint member of a constant velocity universal joint, and superior in maintainability capable of separating the hub wheel and the outside joint member of the constant velocity universal joint. SOLUTION: This bearing device for the wheel is provided by separably joining the hub wheel 1 and a shaft part 12 of the outside joint member of the constant velocity universal joint 3 fitted to and inserted into a hole part 22 of the hub wheel 1 via a recess-projection fitting structure M. The recess-projection fitting structure M of closely contacting the whole area of a fitting contact part 38 of a projection part 35 and a recessed part 36, is constituted by forming the recessed part 36 fitted in close contact to the projection part 35 by the projection part 35 in the other, by pressing the projection part 35 arranged in any one of an outer diameter surface of a shaft part 12 and an inner diameter surface 37 of the hole part 22 of the hub wheel 1 and extending in the axial direction, in the other in the axial direction. The recess-projection fitting structure M allows separation by impartment of extraction force in the axial direction. A foreign matter intrusion preventive means W to the recess-projection fitting structure M is provided. COPYRIGHT: (C)2009,JPO&INPIT

摘要： The present invention firmly connects an inner joint component and a shaft of a constant velocity universal joint, making it difficult for backlash to occur. An axis hole inner diameter 26 of an inner member 20 of the constant velocity universal joint is unhardened, and a spline 54 serving as a recess and projection section running along a circumferential direction is formed on an axial end outerdiameter 52 of the shaft 50. A hardened layer n is formed on the axial end outer diameter 52 of the shaft 50. The shaft 50 and the inner member 20 are joined by an axial end of the shaft 50 being pressed into the axis hole inner diameter of the inner member 20 to incuse a shape of said recess and projection section onto the axis hole inner diameter 26 of the inner member 20.
