<p>PROBLEM TO BE SOLVED: To provide a joint device that has high durability and a joint coupling method that can offer joint coupling with high durability. SOLUTION: With a first joint on a first body and a second joint on a second body coupled together, a separating means separates the second body from a second joint mounting plate on the second body to thereby reduce the inertial mass of the second joint mounting plate and improve the durability.</p> |
