Mechanism for raising and lowering windowpane

摘要

A mechanism for raising and lowering a windowpane achieves a satisfactory mounting of a guide rail to a drum housing to allow visual checking of the mounted state of the guide rail to the drum housing. Relative movement between the guide rail and the drum housing is restricted in the vehicle widthwise direction after completion of the mounting. An engaging projection formed at the end of the drum housing projects toward the guide rail. An engaging portion of the guide rail restricts relative movement between the guide rail and the drum housing in the vehicle widthwise direction by being engaged with the engaging projection.

主权项

1. A windowpane raising and lowering mechanism comprising:
a guide rail which slidably guides a slider base therealong, a windowpane is fixed to said slider base; a wire guide member which is provided at one end of said guide rail; a drum housing which is provided at another end of said guide rail and supports a wind-up drum which is driven to rotate by a drive portion; and a drive wire which extends from said slider base and is wound around said wire guide member and said wind-up drum, wherein an engaging portion is formed on said another end of said guide rail, said engaging portion is arranged to engage with an engaging projection of said drum housing; wherein an end surface of said drum housing comprises a contacting surface which contacts an edge of said engaging portion; wherein said engaging projection is formed on said end surface and projects through said guide rail; and wherein said engaging portion restricts relative movement between said guide rail and said drum housing in a vehicle widthwise direction by engaging a generally planar vertical outer side of said engaging projection of said drum housing.
