PURPOSE: To increase the maximum crossed axes angle of a joint by arranging a portion which is off-center in a radial plane relative to a central ball, and arranging a central spider element in an element connecting tulip element and tripod element, in each arms of a tripod element. CONSTITUTION: A tripod element 3 is fixed on a bowl element 9 connected to a wheel stub-axle 11 which constitutes an output part of a joint. The petal elements 8 of the tulip element 1 formed in one body with a driving shaft are arranged with equal spaced angle, and have two rolling tracks 7 cooperative with each rollers 6. Each arm of the tripod element 3 has a portion 15 which is off-center in a radial plane relative to a central ball, and two flat surfaces 19 are provided between the spherical sectors. And a spider element 24 is arranged in a connecting element which axially connects the tulip element 1 to the tripod element 3. The spider element can radially move relative to the tulip element 1 and can be in rotation with the tulip element 1 about the general axis X-X of the joint. And, the spider element 24 and the eccentric portion 15 of the arm of the tripod element 3 are combined.
