Abstract

A vehicle door glass elevating/lowering device performs elevating/lowering operation of window glass by a driving force of a drive source along a sash member along one of front and rear edges of the window glass in a door sash forming a window opening. The glass elevating/lowering device includes: a guide rail on the sash member; a slider having a glass support secured to the glass and a sliding part guided movably in the elevating/lowering directions with respect to the guide rail; and a transmission member that transmits the driving force of the drive source, in which a first sliding part regulated in position by the guide rail in at least one direction of the vehicle front-rear directions and a second sliding part regulated in position by the guide rail in at least the other direction of the vehicle front-rear directions are provided at mutually different positions in the elevating/lowering directions.

First claim

The invention claimed is:

1. A vehicle door opening/closing member driving device that moves an opening/closing member along an upright pillar sash forming a window opening and that opens and closes the window opening by the opening/closing member, the vehicle door opening/closing member driving device comprising:
a guide rail provided at the upright pillar sash to extend in opening/closing directions of the opening/closing member;
a first sliding part and a second sliding part that are provided on the opening/closing member at different positions in the opening/closing directions and configured to be inserted inside the guide rail and movably guided in the opening and closing directions; and
a passage part that is provided in the middle of the guide rail in the opening and closing directions and that allows at least one of the first sliding part or the second sliding part to be inserted into and removed from the inside of the guide rail in a direction intersecting the opening and closing directions,
wherein a distance between the first sliding part and the second sliding part in the opening and closing directions is longer than a length from the passage part to one end of the guide rail in the opening and closing directions.

2. The vehicle door opening/closing member driving device according to claim 1 , further comprising:
a transmission member that transmits a driving force of a drive source to the opening/closing member; and
a first opening/closing member support and a second opening/closing member support which are separately provided in the opening/closing directions and respectively secured to the opening/closing member,
wherein the first opening/closing member support is located at an upper position in the opening/closing directions while the second opening/closing member support is located at a lower position in the opening/closing directions,
wherein the first sliding part is connected to the first opening/closing member support and the second sliding part is connected to the second opening/closing member support, and
the transmission member is connected to the first opening/closing member support.

3. The vehicle door opening/closing member driving device according to claim 2 ,
wherein a transmission receiving part of the glass first opening/closing member support to which the transmission member is connected, and the first sliding part and the second sliding part, are arranged at different positions in the vehicle front-rear directions.

4. The vehicle door opening/closing member driving device according to claim 1 , further comprising:
a single opening/closing member support secured to the opening/closing member;
wherein the first sliding part and the second sliding part are connected to the single opening/closing member support.

5. The vehicle door opening/closing member driving device according to claim 1 ,
wherein the guide rail has a section surrounded by walls located in the vehicle front-rear directions and the vehicle interior and exterior directions, and the first sliding part and the second sliding part are inserted into the section,
each of the first sliding part and the second sliding part includes:
a sliding base whose outer surface is in sliding contact with each of the walls surrounding the section; and
at least one of: a deflection suppression part that is biased in the vehicle interior and exterior directions to come in contact with the wall within the section so as to suppress deflection of each of the sliding parts in the vehicle interior and exterior directions; or a deflection suppression part that is biased in the vehicle front-rear directions to come in contact with the wall within the section so as to suppress deflection of each of the sliding parts in the vehicle front-rear directions.

6. The vehicle door opening/closing member driving device according to claim 5 ,
wherein the first sliding part is located at an upper position in the opening/closing directions while the second sliding part is located at a lower position in the opening/closing directions,
the deflection suppression part that suppresses deflection of the first sliding part in the vehicle front-rear directions protrudes from the sliding base to the outer peripheral side of the window opening to bias the sliding base toward the inner peripheral side of the window opening, and
the deflection suppression part that suppresses deflection of the second sliding part in the vehicle front-rear directions protrudes from the sliding base to the inner peripheral side of the window opening to bias the sliding base toward the outer peripheral side of the window opening.

7. A door frame assembly equipped with the vehicle door opening/closing member driving device according to claim 1 ,
wherein the opening/closing member driving device including the guide rail is provided on the upright pillar sash so as to provide a door frame assembly including at least the upright pillar sash, the opening/closing member, and the opening/closing member driving device.

8. A vehicle door glass elevating/lowering device that performs elevating/lowering operation of window glass by a driving force of a drive source along a sash member along one of front and rear edges of the window glass in a door sash forming a window opening, the glass elevating/lowering device comprising:
a guide rail provided on the sash member and extending in elevating/lowering directions of the window glass;
a slider having a glass support secured to the window glass and a sliding part guided movably in the elevating/lowering directions with respect to the guide rail; and
a transmission member that transmits the driving force of the drive source,
wherein the sliding part includes: first and second sliding parts disposed at different positions in the elevating/lowering directions, the first sliding part regulated in position by the guide rail in at least one direction of the vehicle front-rear directions, and the second sliding part regulated in position by the guide rail in at least the other direction of the vehicle front-rear directions,
the guide rail has a section surrounded by walls located in the vehicle front-rear directions and the vehicle interior and exterior directions, and the first sliding part and the second sliding part are inserted into the section,
each of the first sliding part and the second sliding part includes:
a sliding base whose outer surface is in sliding contact with each of the walls surrounding the section; and
at least one of: a deflection suppression part that is biased in the vehicle interior and exterior directions to come in contact with the wall within the section so as to suppress deflection of each of the sliding parts in the vehicle interior and exterior directions; or a deflection suppression part that is biased in the vehicle front-rear directions to come in contact with the wall within the section so as to suppress deflection of each of the sliding parts in the vehicle front-rear directions.
