Abstract

To provide a window regulator and a method of assembling the same, capable of easily applying grease to a wire facing surface of a guide rail, the window regulator includes: a guide rail extending in an operation direction of a window glass; a slider installed to the window glass and guided along the operation direction on the guide rail; and a wire configured to drive the slider along the operation direction with respect to the guide rail, wherein the guide rail has a wire facing surface facing the wire along the operation direction, and the slider has a grease application portion for applying grease along the operation direction on the wire facing surface.

Claims

1. A window regulator comprising:

a guide rail extending in an operation direction of a window glass;

a slider installed to the window glass and guided along the operation direction on the guide rail; and

a wire configured to drive the slider along the operation direction with respect to the guide rail, wherein

the guide rail has a wire facing surface facing the wire along the operation direction, and

the slider has a grease application portion for applying grease along the operation direction on the wire facing surface.

2. The window regulator according to claim 1, wherein

the grease application portion abuts on the wire facing surface in an elastically deformed state.

3. The window regulator according to claim 1, wherein

the grease application portion includes a cantilever-shaped spring piece extending toward the wire facing surface, and

a stopper for regulating elastic deformation of the spring piece is formed in at least one of a basal end side and a tip side of the spring piece.

4. The window regulator according to claim 1, wherein

two grease application portions are provided in different locations in a direction intersecting the operation direction, and

a grease storage groove is formed between the two grease application portions.

5. The window regulator according to claim 4, wherein

the two grease application portions are provided in different locations in the operation direction.

6. The window regulator according to claim 1, wherein

the slider has a wire end housing portion for housing a wire end of the wire, and

the grease application portion is formed in the wire end housing portion.

7. The window regulator according to claim 1, wherein

the slider has a slider shoe that supports at least a part of the guide rail, and

the grease application portion is provided in a location different from that of the slider shoe in a direction intersecting the operation direction.

8. A method of assembling the window regulator according to claim 1, the method comprising:

a driving step of driving the slider along the operation direction with respect to the guide rail using the wire; and

a grease application step of applying grease along the operation direction on the wire facing surface of the guide rail using the grease application portion of the slider.
