PURPOSE: Ball structure for connecting a roller of a regulator bar for a door window glass is provided to improve performance, to reduce the weight, and to extend the life span by reducing frictional resistance of the roller reciprocating and sliding in a channel guide. CONSTITUTION: A roller is installed between an end of an X-type bar(1) and a groove(4) of channel guides(2,3), and the roller is connected to a roller shaft(6) through a ball(7). Horizontal grooves(9) are arranged at equal intervals around a vertical shaft(8) and formed in the ball. Lubricant is charged in horizontal grooves, and the ball is made of metal or synthetic resin. Installation clearance between the roller and the ball is reduced with improving lubricating efficiency of the ball. Noise from clearance is prevented in operating the regulator, and endurance is improved with reducing frictional resistance.
