The lifting window (15) has a windowpane (17) which can be raised and lowered by means of a lifting device and which is guided here by two guide rails (24; 25). In the region of at least one side edge (19), the windowpane (17) is guided, at a point remote from the lifting device, only indirectly by the associated guide rail (24) by means of an adjusting device (38). The adjusting device (38) has a guide strip (39) which interacts with the associated guide rail (24). The guide strip (39) is guided by means of a guide device (41) so as to be moveable at least approximately perpendicularly to the windowpane (17). Said guide strip (39) can be adjusted relative to the windowpane (17) by means of an adjustment device (42) and can be fixed in the desired relative position by means of a fixing device.
