window regulator

Abstract

A vehicle window regulator having: a guide rail fixed to a vehicle door panel; and a slider supporting a window glass and supported so as to be slidable in a longitudinal direction of the guide rail along sliding surfaces on the front and back of the guide rail, The sliding part of the guide rail that slides relative to the slider has a first sliding surface and a second sliding surface, and the first sliding surface and the second sliding surface face one side and the other in the direction of the inside and outside of the vehicle, and the slider has a grease injection part. , the grease injection part has: an injection space, which opens in the direction of the inside and outside of the vehicle, and the first sliding surface of the guide rail is located inside the injection space; and a grease receiving part, which is located at a position opposite to the second sliding surface of the guide rail, receiving Grease injected into the injection space. The grease injection portion can simply and reliably supply grease to the sliding portion between the first sliding contact surface and the second sliding contact surface of the guide rail and the slider.

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
