A window regulator includes a metal guide rail provided along an ascending/descending direction of a window of a vehicle, a carrier plate that slides on the guide rail and moves together with the window, a drum rotationally driven by a motor, a cable that is routed between the drum and the carrier plate via a direction changing member provided at an upper end of the guide rail and pulls the carrier plate, and a cable support that supports the cable between the drum and the direction changing member. The cable support includes a resin slide member allowing the cable to slide thereon and an attached-member receiving portion to which the slide member is attached.
