To provide a window regulator and a method of assembling the same, capable of easily supplying grease to a slider shoe and a support portion of a guide rail, the window regulator includes: a guide rail extending in an operation direction of a window glass; and a slider installed to the window glass and guided along the operation direction on the guide rail. The slider has a slider shoe configured to support at least a part of the guide rail, and a grease injection hole configured to inject grease into an internal space of the slider shoe.
1. A window regulator comprising:
a guide rail extending in an operation direction of a window glass; and
a slider installed to the window glass and guided along the operation direction on the guide rail, wherein
the slider has:
a slider shoe configured to support at least a part of the guide rail; and
a grease injection hole configured for injection of grease into an internal space of the slider shoe,
the guide rail has a main wall portion facing the slider in a vehicle width direction and extending in a front-rear direction, a side wall portion extending from the main wall portion in the vehicle width direction, and a spacing portion extending in the front-rear direction to be separate from the side wall portion,
the slider shoe has a front-rear direction nipping portion configured to nip the side wall portion from the front-rear direction and a vehicle width direction nipping portion configured to nip the spacing portion from the vehicle width direction, and
the grease injection hole is formed to communicate with the front-rear direction nipping portion.
2. The window regulator according to claim 1 , wherein
the slider has a grease supply portion configured to supply the grease injected into the grease injection hole to the slider shoe and a support portion of the guide rail.
3. The window regulator according to claim 1 , wherein
at least two sets of the slider shoes and the grease injection holes are provided in different locations in the operation direction.
4. The window regulator according to claim 1 , wherein
the slider has a grease application portion configured to apply grease to the spacing portion of the guide rail in a location different from those of the slider shoe and the grease injection hole in the operation direction.
5. The window regulator according to claim 4 , wherein
the grease application portion abuts on the spacing portion of the guide rail in an elastically deformed state.
6. A method of assembling the window regulator according to claim 1 , the method comprising:
a grease injection step of injecting the grease into an internal space of the slider shoe from the grease injection hole;
a driving step of driving the slider along the operation direction with respect to the guide rail; and
a grease supply step of supplying grease to the slider shoe and a support portion of the guide rail.
