When the window glass B is lifted and lowered, the roller unit 70 fitted to the guide rails 30, 30 is guided to move up and down, but the flat roller 74 is pressed against the side wall 33 by the elastic force of the spring 78. Therefore, the roller 71 and the flat roller 74 are urged in the width-expanding direction with respect to each other.
The flat roller 74 is pressed against the side wall 31 while being fitted to the side wall 32.

The urging force of the spring 78 is increased by the lever action due to the eccentricity between the pivot shaft 76 that pivotally supports the swing lever 75 and the eccentric shaft 77, and the flat roller 74
Is strongly pressed against the side wall 33, so even if there is an error in the direction in which the groove 32 separates from the side wall 33, the roller unit 70 rattles via the roller 71 and the flat roller 74 due to the biasing force of the spring 78. It is fitted to the guide rail 30 without any.

Since the groove 32 is provided on one side wall 31 and the other side wall 33 has no groove and is flat, even if the groove 32 has an error in a direction parallel to the side wall 33, the flat roller 74 causes the side wall 33 to have an error. There is no problem simply by moving on the surface of the guide rail 30 and it is an escape for obtaining the dimensional accuracy of the guide rail 30 itself.

[Advantages of the Invention] According to the windowpane elevating / lowering device of the present invention, the whole base is unitized based on the base member provided with the two guide rails, and the flat integral shape is set. It can be brought to the attachment site with excellent assembly.

Since the window glass is supported by a pair of guide rails arranged in parallel in front of and behind the window glass, the supporting rigidity is high and the positional relationship of each member does not fluctuate. Positioning of each member is easy and almost no adjustment is required, and the assembling property is also very good in this respect.

In particular, since the balancer is fixed to the base member at an intermediate position between the pair of guide rails, the balancer does not interfere with other members, and it is possible to equip the balancer with sufficient performance, good operation and durability. It can be a window glass lifting device.
