PURPOSE: A lubricator for an arm of a window regulator in a vehicle is provided to prevent a generation of abnormal sound and to improve the durability. CONSTITUTION: When an electromotor is driven, a worm gear is driven and its rotating force is transferred to a worm wheel. A rotating direction of a driving shaft in the electromotor is converted to a right angle by the worm wheel. A main arm is rotated centering a pivot by rotating a sector gear butted with the worm wheel according to the rotation of the worm wheel. A side window glass is moved upward and downward according to the rotating direction of the electromotor by guiding the main arm in a guide channel with a sub arm(58). A grease is spread around a disc(66) through an injecting hole of grease(10). Thereby a generation of abnormal sound is prevented by reducing a metal rubbing around the pivot and the reliability of a product is improved by improving the durability around the pivot.
