PURPOSE: A universal joint is provided to prevent rattle noise in turning the universal joint by tilting with inserting a spider into a yoke, and with sealing two spiders by a bellows cap including lubricant. CONSTITUTION: A universal joint is composed of two yokes(10) having opening parts(11), and bending by engaging opening parts, and two spiders(20) having sliding grooves at sides to settle yokes, and mounting four coil springs(23) to contact yokes to sliding grooves. Two spiders are inserted to opening parts of the yokes, and installation grooves are formed between sliding grooves of spiders to mount coil springs. The yokes are connected to shafts(40,50), and moved up and down or right and left by inserting the spiders. Two yokes and two spiders are covered with a bellows cap(30), and both ends of the bellows cap are sealed with bands(32) by filling the bellows cap with lubricant(31). The universal joint is bent with the bellows cap, and rattle noise is absorbed with lubricant.
