Abstract:
1. A slidable constant velocity universal joint, comprising: an outer joint member configured to connect to a power transmission member through a female spline and a male spline engaged with each other; an inner joint member configured to connect to an end portion of a shaft; an elastic member configured to be disposed at an end of the shaft; a bearing member disposed so as to be interposed between said elastic member and the end of the shaft; a cap member disposed so as to be at the end of the shaft, and having a spherical convex surface portion at a forward end thereof; and a flat surface portion disposed at a center of said forward end of said cap member; wherein said annular spherical convex surface portion is disposed around said flat surface portion, wherein said bearing member has a spherical concave surface portion configured and arranged to guide said spherical convex surface portion while in contact therewith, wherein torque transmission is possible between said outer joint member and said inner joint member while allowing angular displacement and axial displacement, wherein said elastic member is configured and arranged so as to elastically urge said outer joint member toward the power transmission member, wherein said bearing member is configured and arranged so as to guide the end of the shaft while being in contact therewith, and wherein said spherical convex surface portion has a radius of curvature smaller than a radius of curvature of said spherical concave surface portion.
