Abstract: A Cardan-type universal joint has a pair of joint bodies (11) each having a cylindrical hub (12) for securing thereto a rotary shaft (10), and a cross-shaped member (15) for connecting the pair of joint bodies together. Each of the hubs has at least one first slit, or escape slit, (20) formed therein radially inwardly from the circumference thereof having a sector shape with a sectoral angle of not less than 180 degrees and being disposed on a plane intersecting the axis of the shaft at an angle, thereby enabling the joint body to elastically deform in a spring-like manner.

Abstract: A universal joint having two joint bodies coupled together by a coupling member. Each of the joint bodies has a cylindrical hub portion and a pair of yoke portions provided integral with the hub portion by sintering, casting, or injection molding (die casting). The yokes are formed with bearing holes with which sleeve members are force-fittable. The coupling member has a rectangular segment formed with holes and separate pins force-fittable with the holes of the segment. Each of the pins is slidably inserted into each of the sleeve members fitted with the bearing holes, and extends into each of the holes of the rectangular segment.
