The present invention employed an elevating device for a window glass provided in a door of a vehicle, including: a guiding device which is provided in the door; a career plate which engages with the guiding device and slidably moves in an elevating direction of the window glass in relation to the guiding device; and a driving device which raises and lowers the career plate. The career plate is provided with a stopper which abuts on the guiding device when the career plate reaches an elevation-limiting position. The stopper is provided with an attaching portion which is attached to the career plate, and an abutting portion which abuts on the guiding device and elastically deforms when the stopper reaches the elevation-limiting position. The abutting portion is formed such that a width thereof becomes wider than the attaching portion and such that the width becomes smaller toward a distal end side.
