PROBLEM TO BE SOLVED: To provide a universal joint device capable of preventing the swing of connected equipment when connecting and suspending various equipment such as lighting system. SOLUTION: This universal joint device has a cylindrical body 11, a first shaft connection part 12 inserted through an end face on one side of the cylindrical body and connected with the cylindrical body turnably by a first shaft pin 14 capable of coming into slide-contact with an inner peripheral face of the cylindrical body and passing through in the direction of diameter of the cylindrical body, a second shaft connection part 13 inserted through an end face on the other side of the cylindrical body 11 and connected with the cylindrical body turnably by a second shaft pin 15 capable of coming into slide-contact with the inner peripheral face of the cylindrical body and passing through in the orthogonal direction to the first shaft pin and in the direction of diameter of the cylindrical body, and an elastic member 16 inserted between the first shaft connection part and the second shaft connection part to give a stress in the direction in which they are pushed and widened to them. |
