。[Claims for Utility Model Registration] A flow rate generating means that is provided between relatively rotatable input and output shafts and that flows an amount of fluid according to the rotational speed difference between the two shafts, and a flow resistance in a discharge path of the fluid. The torque transmission joint is provided with a means for generating torque, and the transmission torque between the input and output shafts is controlled by the flow resistance of the fluid;
a piston that stops when it hits a stopper at a predetermined temperature; and a spool that moves due to the volumetric expansion of the fluid due to a temperature increase after the piston stops, and is housed so as to continuously narrow the opening area of the discharge passage. A hydraulic power transmission joint characterized by:
