<p>PROBLEM TO BE SOLVED: A joint whose number of parts is reduced and whose production process is simplified. MEANS TO SOLVE THE PROBLEMS: The joint has spherical bodies (29a-29d), a circular cylindrical inner hub (20)in which hemispherical receiving sections (22a-22d) for receiving the spherical bodies (29a-29d) are formed in curved surfaces, and an outer hub (10) that has a receiving section (17) for receiving the inner hub (20) and also has longitudinal grooves (12a-12d) integrally formed with the receiving section (17) and in which the spherical bodies (29a-29d) received in the receiving sections (22a-22d) are received.</p> |
