Mechanism for raising and lowering windowpane

Abstract

A mechanism is obtained for raising and lowering a windowpane, which makes it possible to achieve a satisfactory mounting of a guide rail to a drum housing by visually checking the mounted state of the guide rail to the drum housing without needing a special solution such as providing the drum housing with an inspection hole, and to securely restrict relative movement between the guide rail and the drum housing in the vehicle widthwise direction after completion of the mounting of the guide rail to the drum housing. An engaging projection which projects toward the guide rail is formed at the end of the drum housing on the guide rail side, and an engaging portion, which restricts relative movement between the guide rail and the drum housing in the vehicle widthwise direction by being engaged with the engaging projection from outside to be fixed to the drum housing, is formed at the end of the guide rail on the drum housing side.
