A windowpane lifting mechanism comprises a cable member which is provided to vertically extend in a door shell and connected to a lower end portion of a windowpane by way of a connecting member so that the windowpane is moved up and down to close and open the window in response to up-and-down running of the cable member. The windowpane lifting mechanism further includes a first guide rail member which is provided on one side of the cable member to linearly extend substantially in the vertical direction, a second guide rail member provided to extend substantially in the vertical direction in nonparallel relation to the first guide rail member spaced therefrom by a predetermined distance in the direction of width of the windowpane, a first slider connected to a lower portion of the windowpane and engaged with the first guide rail member to be slidable along the first guide rail member, a second slider connected to a lower portion of the windowpane at a distance from the first slider and engaged with the second guide rail member to be slidable along the second guide rail member.
A windowpane lifting mechanism for a window of a vehicle door comprising a windowpane driving means including a cable member which is provided to vertically extend in a door shell and connected to a lower end portion of a windowpane by way of a connecting member so that the windowpane is moved up and down to close and open the window in response to up-and-down running of the cable member, and a windowpane guiding means including a first guide rail member which is provided on one side of cable member to linearly extend substantially in the vertical direction, a second guide rail member provided to extend substantially in the vertical direction in nonparallel relation to the first guide rail member spaced therefrom by a predetermined distance in fhe direction of width of the windowpane, a first slider connected to a lower portion of the windowpane and engaged with the first guide rail member to be slidable along the first guide rail member, and a second slider connected to a lower portion of the windowpane at a distance from the first slider and engaged with the second guide rail member to be slidable along the second guide rail member, wherein said first guide rail member is disposed near said cable member and extends linearly in the vertical direction in parallel to said cable member, and wherein said first slider is supported so as not to be displaced in the direction of thickness of the door, and wherein second slider is supported so as to be able to be displaced in the direction of thickness of the door, wherein said second slider is displaced under heavy load, but is hardly displaced uunder light load.
A windowpane lifting mechanism for a window of a vehicle door comprising a windowpane driving means including a cable member which is provided to vertically extend in a door shell and connected to a lower end portion of a windowpane by way of a connecting member so that the windowpane is moved up and down to close and open the window in response to up-and-down running of the cable member, and a windowpane guiding means including a first guide rail member which is provided on one side of the cable member to linearly extend substantially in the vertical direction, a second guide rail member provided to extend substantially in the vertical direction in nonparallel relation to the first guide rail member spaced therefrom by a predetermined distance in the direction of width of the windowpane, a first slider connected to a lower portion of the windowpane and engaged with the first guide rail member to be slidable along the first guide rail member, and a second slider connected to a lower portion of the windowpane at a distance from the first slider and engaged with the second guide rail member to be slidable a long the second guide rail member, in which one of said first and second sliders is arranged so as not to permit displacement of the windowpane in the direction of thickness of the door during up-and down movement of the windowpane and the other slider is arranged to permit displacement of the windowpane in the direction of thickness of the door during up-and-down movement of the windowpane, and two pairs of stabilizers are provided adjacent to the upper edge of the door panel, the pairs of stabilizers being spaced from each other in the direction of width of the windowpane and the stabilizers of each pair being opposed to each other on opposite sides of the windowpane and being in a sliding contact with the windowpane to restrict displacement of the windowpane in the direction of thickness of the door.
