A window regulator comprising: a carrier plate holding a window glass, a guide rail guiding the carrier plate movably in elevating/lowering direction, a direction-changing member fixed on a top end portion and / or a bottom end portion of the guide rail, an inner cable (16, 17) wound around the direction-changing member and fixed to the carrier plate, and a driving mechanism having a drum rewinding the inner cable and a driving motor for rotating the drum; wherein: an elastic member is fixed to the carrier plate; a receiving part is formed around the bottom end portion of the guide rail for regulating the declination of the carrier plate by contacting with the elastic member; the elastic member has a fixing part fixed to the carrier plate and a contacting part for contacting with the receiving part, wherein the contacting part has an approximately triangle prism configuration being convex downward in front vision, the contacting part has a chamfered part at a side close to the guide rail, the chamfered part is gradually declined downwardly relative to a surface at right angle to the guide rail as the distance from the guide rail increases, and a bottom on the back side of the contacting part, which is an edge line of the triangle prism, is formed perpendicular to the guide rail, characterized in that the receiving part has a base part which is on a close side to the guide rail and an inclined surface which is on an opposite side to the guide rail to be abutted with the elastic member, wherein the base part is substantially perpendicular to the guide rail, the inclined surface is gradually inclined upwardly relative to a surface perpendicular to the guide rail as the distance from the guide rail increases, so that when the elastic member abuts the receiving part, resulting in stopping of the window glass descending, the chamfer part of the elastic member abuts the base part of the receiving part and the bottom of the triangle prism of the contacting part abuts the inclined surface of the receiving part. a carrier plate holding a window glass, a guide rail guiding the carrier plate movably in elevating/lowering direction, a direction-changing member fixed on a top end portion and / or a bottom end portion of the guide rail, an inner cable (16, 17) wound around the direction-changing member and fixed to the carrier plate, and a driving mechanism having a drum rewinding the inner cable and a driving motor for rotating the drum;
