PROBLEM TO BE SOLVED: To provide a spherical shaft coupling device capable of preventing rotation in one direction. SOLUTION: The spherical shaft coupling device 1 includes a bearing member 20 interposed between a housing 10 and a spherical shaft 24 disposed concentrically with each other, and the spherical shaft 24 supported rotatably in three-dimensional directions. Both ends of an outer member 11 of the housing 10 are provided with a pair of brackets 41, 41 projecting in the axial direction, and a pair of stoppers 43, 43 are fastened to the pair of brackets 41, 41 by bolts 46. Both brackets 41, 41 are arranged to face a pair of connection parts 26, 26 protrusively provided at the spherical shaft 24. When turning force in a direction of an arrow mark R is applied to the spherical shaft 24, one of the pair of connection parts 26, 26 contacts one of the pair of stoppers 43, 43 to prevent the rotation of the spherical shaft 24 in the direction of the arrow mark R.
