PURPOSE: A universal joint of a steering device for a vehicle is provided to transfer power even if a power transfer member is worn away by forming a rotary member capable of a rolling contact between an inner member and an outer member of the universal joint. CONSTITUTION: A universal joint(400) of a steering device for a vehicle comprises a yoke joint(110), an outer member(122), an inner member(124), and an elastic bush(300). Multiple outer coupling grooves(360) are formed in the inner surface of the outer member. The inner member is inserted into the outer member. Multiple inner coupling grooves(370) are formed on the outer surface of the inner member. The elastic bush is inserted between the outer member and the inner member and has a mounting unit in which a power transfer member and a cylindrical rotary member are inserted. |
