<P>PROBLEM TO BE SOLVED: To improve durability, to secure spherical surface retention force by a spherical pair, to facilitate assembly, and to achieve a high angle and miniaturization. <P>SOLUTION: A cylindrical outer ring 30 is commonized, a fixed type joint part 10 is disposed at one end thereof, and a sliding type joint part 20 is disposed at another end thereof. A convex spherical surface part 25 is provided at an end part of the shaft 21 spline-fitted to an inner ring 22 of the sliding type joint part 20, and a concave spherical surface part 15 is provided at an end part of the shaft 11 spline-fitted to an inner ring 12 of the fixed type joint part 10. The fixed type joint part 10 and the sliding type joint part 20 are connected through a spherical pair 40 comprising the convex spherical surface part 25 and the concave spherical surface part 15. The convex spherical surface part 25 comprises a hollow shaped head part 50 spherically fitted in an inner spherical surface of the concave spherical surface part 15 and a neck part 21b axially slidably inserted and fitted in a hollow part 52 of the head part 50. <P>COPYRIGHT: (C)2010,JPO&INPIT |
