A universal joint includes a tube having a hollow shape; a slip bush inserted into the tube; and a shaft assembled with the tube through the slip bush, wherein the slip bush includes power transmission parts, which are arranged along an circumferential surface of the slip bush in an axial direction and have pins positioned at centers of the power transmission parts and supports supporting both ends of each pin, and elastic parts, which are arranged along the circumferential surface of the slip bush while being spaced from the power transmission parts and have a section with a C-shape, which is formed in such a manner that a side portion is cut out in the axial direction. Therefore, strength and rigidity are improved, even when twist is generated in the universal joint, so that clearance and noise due to abrasion, pressing, etc. can be minimized.
