PROBLEM TO BE SOLVED: To reduce a dimension in the axial direction of a spherical face shaft coupling. SOLUTION: The spherical face shaft coupling 1 consists of a bearing recessed part 12 which is opened at a drag link end 11 and in which a substantially semi-spherical recessed spherical face part 13 is formed in an upper part, a projecting spherical face part 21 formed in a lower end part of a spherical face shaft 20, a bearing member 30 whose recessed spherical face part 33 formed by an upper seat part 31 and a lower seat part 32 is slidably fitted in the projecting spherical face part 21 and is fitted in the bearing recessed part 12, a cushion member 40 arranged on an outer face on a lower end opening side of the bearing recessed part 12 of the bearing member 30, and an end cap 50 fixed to a lower end opening of the bearing recessed part 12 to compress and deform the cushion member 40. Consequently, since the projecting spherical face part is pressed and is brought into contact with the bearing recessed part by a spring force of the cushion member through the bearing member, it is turnably supported in the bearing recessed part in three-dimensional direction while preventing a play to reduce a dimension in the axial direction.
