PROBLEM TO BE SOLVED: To reduce the number of part items and assembling man-hours. SOLUTION: A bearing member 4 integrated with an upper bearing and a lower bearing is coupled with a shaft section 6, and a spherical shaft 5 is inserted into the bearing recess 3 of a tie rod end 2. A cushion member 11 made of an elastic body is inserted into the bearing recess 3, and an opening section 7 is closed and caulked by an end cap 9 having a slide curved section 10. The shaft section 6 is pressed and held without backlash and supported rotatably in the three-dimensional direction on the bearing recess 3 by the cushion member 11 applied with a reaction force from the end cap 9 via the bearing member 4. Since the spherical shaft 5 can be supported rotatably in the three-dimensional direction on the bearing recess 3 by the bearing member 4, the elastic body, and the end cap 9, the number of part items and assembling man-hours can be reduced, and the manufacturing cost of this spherical shaft joint device can be reduced.
