Window regulator

Abstract

A window regulator comprising a guide rail that is fixed to a vehicle door panel, and a slider base that supports a window glass and is supported so as to be slidable, in a lengthwise direction of theguide rail, along front and back sliding surfaces of the guide rail, said window regulator having, on the guide rail, a first sliding surface and a second sliding surface, sliding sections thereof facing toward one and the other of vehicle interior / exterior directions, said sliding sections being where sliding occurs with the slider base, wherein a grease injection section is provided to the slider base, said grease injection section having an injection space that opens in a vehicle interior / exterior direction and has the first sliding surface of the guide rail positioned in an interior thereof, and having a grease receiving section that is positioned facing the second sliding surface of the guide rail and receives grease injected into the injection space. Due to this grease injection section, grease can be simply and reliably supplied to the sliding sections where sliding occurs between the slider base and the first and second sliding surfaces of the guide rail.

Description

technical field [0001] The present invention relates to a window regulator for raising and lowering the window glass of a vehicle. Background technique [0002] As a window regulator for vehicles, the slider (glass carrier) on which the window glass is fixed is supported so as to be movable in the longitudinal direction of the guide rail, and the slider is pulled by a wire so that the slider is relative to the guide rail. Window regulators that slide to move up and down the window glass are widely used. In such a window regulator, grease is applied to a sliding contact portion between the guide rail and the slider so that the slider slides smoothly with respect to the guide rail. [0003] In Patent Document 1, a window regulator is proposed in which a closed space capable of accommodating grease and a through hole communicating the closed space with the outside are provided on a slider, and the grease is injected into the closed space through the through hole. In the inner...

Problems solved by technology

[0006] However, for a window regulator of the type that has a sliding surface on the front and back of the plate-shaped guide rail, and the sliding seat can be brought into sliding contact with the sliding surface of the front and back, even if the sliding seat is formed on the sliding surface as in Patent Document 1, There are through holes, but there is also the following problem: Grease cannot be applied to the sliding surface on the opposite side (back side) of the rail from the side facing the through holes just by injecting grease from the through holes.

Therefore, a process of applying grease to the sliding surface on the back side of the guide rail is required independently of injecting grease from the through hole, resulting in an increase in man-hours and complexity of the device for applying grease. change
