PROBLEM TO BE SOLVED: To provide a porous solid lubricant sealed universal joint excellent in lubricating performance, long in life span, free to be driven even in high speed rotation, free to comparatively easily simplify a manufacturing process, capable of meeting a demand for cost reduction and excellent in heat resistance and durability. SOLUTION: This porous solid lubricant sealed universal joint is constituted in such a manner that rotating torque is transmitted by the engagement of track grooves 4, 5 formed at an outer member 2 and an inner member 3 and a torque transmitting member 6, the torque transmitting member 6 moves in the axial direction by rolling along the track grooves 4, 5 and the porous solid lubricant 10 is sealed in the joint. The porous solid lubricant 10 is produced by occluding a lubricating component in a resin skeleton by foaming and hardening a foaming liquid silicone component together with the lubricating component.
