[Detailed Description of the Invention] The present invention is used for the connection between the arm and the guide rail that supports the window glass in an arm-type automobile window regulator, or the connection between the arm and the guide rail of the door panel.
This invention relates to a guide slider having a spacer function.

FIG. 1 shows an example of an automobile window regulator, in which a link mechanism 2 for vertically moving a window glass 1 of a door (not shown) includes one main arm 3 facing diagonally, and two main arms 3 facing diagonally. Book sub-arm 4,
It is composed of 5 and 5.

A sub-arm 4 facing diagonally upward is arranged on the near side of the main arm 3, and a sub-arm 5 facing diagonally downward is arranged on the opposite side, and their bases are arranged as follows.
It is pivotally connected to the middle part of the main arm 3 by a common shaft.

As shown in FIG. 4, a support shaft 10 is fixed to the upper end of the main arm 3 and the end of the sub-arm 4 with a screw 10a. Guide rollers 7 and 8 having spherical holes are pivotally attached to the spherical portion 10b at the end of the support shaft 10, and both rollers 7 and 8
is rotatably fitted into a channel-shaped horizontal guide rail 9 that is movable up and down.
A base of a window glass 1 of a door (not shown) is attached to the guide rail 9.

A guide roller 11 is pivotally attached to a similar support shaft 10 fixed to the lower end of the other sub-arm 5, and the roller 11 is attached to a door panel (not shown).
The guide rail 12 is rotatably fitted into a channel-shaped guide rail 12 that is horizontally fixed to the guide rail 12 .

The main arm 3 is attached to a holding member 13 fixed to the door panel at a position slightly above its lower end.
It is pivotally mounted on a shaft 14. A sector gear 15 fixed to the lower end of the main arm 3 is attached to the holding member 1.
It meshes with a pinion 17 which is pivotally connected to the shaft 16 at the shaft 16.

An operation handle (not shown) is attached to the shaft 16, and the pinion 17 is operated by operating the handle (not shown).
By rotating the main arm 3, the main arm 3 is vertically swung around the shaft 14 via the sector gear 15, and the window glass 1 is moved vertically.

If the door to which the window glass 1 is attached has a curved surface when viewed from the side in FIG.
moves along a curved trajectory, so each arm 3,
The ends of rollers 4 and 5 can be appropriately inclined with respect to guide rails 9 and 12, and each guide roller 7, 8, and 11 can be moved within its respective guide rail without play. There is a need.

For this purpose, each arm 3, 4, 5 with a guide roller 7, 8, 11 attached, and a guide rail 9,
The support shaft 10 between the support shafts 12 is generally fitted with a spacer having elasticity in the axial direction to prevent rattling.

FIGS. 2 and 3 show examples of conventional anti-backlash spacers 18 and 19 for this purpose, respectively.

The spacer 18 shown in FIG. 2 has a conical shape, and the support shaft 10 is fitted into a hole 18b formed in the top portion 18a. The flange 18c provided at the lower part of the spacer 18 is in pressure contact with the guide rails 9, 12, and the top 18a is connected to each arm 3,
They are pressed against the ends of 4 and 5, respectively.

Although this spacer 18 is relatively large and has excellent strength, it has the disadvantage of poor elasticity.

The spacer 19 shown in FIG. 3 has a plurality of legs 19b inclined inward from a flange 19a provided at the bottom, and a hole 19c formed at the free end of the leg 19b is provided with a support hole 19c. It is fitted onto the shaft 10.

Although this spacer 19 is relatively large and has excellent elasticity, the legs 19b are easily damaged, and the broken legs 19b may become entangled with the support shaft 10 or get inside the guide rails 9, 12. This may adversely affect the rolling motion of the guide rollers 7, 8, 11, or the elastic force may decrease, causing the guide rollers 7, 8, 11 to move against the guide rails 9, 12.
The disadvantage is that the function to prevent rattling is lost.

The purpose of this invention is to attach an approximately rectangular parallelepiped slider body to a support shaft provided at the end of an arm, and to arrange this slider body to be slidable within a guide rail. A pair of elastic members extending in the direction of movement from the sides of the child body are curved, the free ends of which are attached to the support shaft, and the appropriate positions of the curved portions are brought into contact with the arm, thereby serving as a spacer. An object of the present invention is to provide a guide slider for an automobile window regulator.
