A window regulator comprising a guide rail that is fixed to a vehicle door panel, and a slider base that supports a window glass and is supported so as to be slidable, in a lengthwise direction of the guide rail, along front and back sliding surfaces of the guide rail, said window regulator having, on the guide rail, a first sliding surface and a second sliding surface, sliding sections thereof facing toward one and the other of vehicle interior/exterior directions, said sliding sections being where sliding occurs with the slider base, wherein a grease injection section is provided to the slider base, said grease injection section having an injection space that opens in a vehicle interior/exterior direction and has the first sliding surface of the guide rail positioned in an interior thereof, and having a grease receiving section that is positioned facing the second sliding surface of the guide rail and receives grease injected into the injection space. Due to this grease injection section, grease can be simply and reliably supplied to the sliding sections where sliding occurs between the slider base and the first and second sliding surfaces of the guide rail.
