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.
