WINDOW REGULATOR AND GUIDE RAIL ATTACHING METHOD

Abstract

A window regulator includes a guide rail and a drum housing at an end of the guide rail. The guide rail includes a flat plate portion extending in the ascending/descending direction, and a side plate portion rising from the flat plate portion. The drum housing includes a fitting hole into which the end of the guide rail is inserted and fitted, a first fitting guide wall extending from a first inner surface of the fitting hole toward the near side in an insertion direction so as to protrude from an edge of the fitting hole and guiding the flat plate portion to the fitting hole, and a second fitting guide wall extending from a second inner surface of fitting hole toward the near side in the insertion direction so as to protrude from the edge of the fitting hole and guiding the side plate portion to the fitting hole.

Description

Claims

1. A window regulator, comprising: a guide rail provided along an ascending/descending direction of a window glass of a vehicle;a carrier plate that supports the window glass and is slidably attached to the guide rail;a wire to pull the carrier plate;a rotating drum to take up and feed out the wire by rotating; anda drum housing being provided at an end of the guide rail and housing the rotating drum,wherein the guide rail comprises a flat plate portion extending in the ascending/descending direction, and a side plate portion rising from the flat plate portion, andwherein the drum housing comprises a fitting hole into which the end of the guide rail is inserted and fitted, a first fitting guide wall extending from a first inner surface of the fitting hole toward the near side in an insertion direction so as to protrude from an edge of the fitting hole and guiding the flat plate portion to the fitting hole, and a second fitting guide wall extending from a second inner surface of fitting hole toward the near side in the insertion direction so as to protrude from the edge of the fitting hole and guiding the side plate portion to the fitting hole.

2. A window regulator, comprising: a guide rail provided along an ascending/descending direction of a window glass of a vehicle;a carrier plate that supports the window glass and is slidably attached to the guide rail;a wire to pull the carrier plate; anda rotating drum to take up and feed out the wire by rotating; andwherein the guide rail comprises a flat plate portion extending in the ascending/descending direction, and a side plate portion rising from the flat plate portion, andwherein the carrier plate comprises an insertion portion into which the guide rail is inserted, a first insertion guide wall extending from a first inner surface of the insertion portion toward the near side in an insertion direction so as to protrude from an edge of the insertion portion on the near side in the insertion direction and guiding the flat plate portion to the insertion portion, and a second insertion guide wall extending from a second inner surface of the insertion portion toward the near side in the insertion direction so as to protrude from the edge of the insertion portion on the near side in the insertion direction and guiding the side plate portion to the insertion portion.

3. A guide rail attaching method for attaching the guide rail to the drum housing in the window regulator according to claim 1, the method comprising: after bringing the flat plate portion and the side plate portion respectively into contact with the first fitting guide wall and the second fitting guide wall, moving the guide rail toward the fitting hole while keeping the flat plate portion and the side plate portion respectively in sliding contact with the first fitting guide wall and the second fitting guide wall, thereby inserting the guide rail into the fitting hole.

4. A guide rail attaching method for attaching the guide rail to the carrier plate in the window regulator according to claim 2, the method comprising: after bringing the flat plate portion and the side plate portion respectively into contact with the first insertion guide wall and the second insertion guide wall, moving the guide rail toward the insertion portion while keeping the flat plate portion and the side plate portion respectively in sliding contact with the first insertion guide wall and the second insertion guide wall, thereby inserting the guide rail into the insertion portion.
