Abstract

The present disclosure relates to an automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.

First claim

What is claimed is:

1 . An automotive slide member comprising:
a first slide portion including a first friction slide mechanism having at least two first portions, and a first lubricant applied between the first portions; and a second slide portion including a second friction slide mechanism having at least two second portions, and a second lubricant applied between the second portions, wherein: the first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile; the second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile; the first lubricant contains a first base oil and an additive; the second lubricant contains a second base oil and an additive containing conductive carbon; and the second lubricant contains a relatively larger amount of the conductive carbon than an amount of conductive carbon in the first lubricant.

2 . The automotive slide member according to claim 1 , wherein the first lubricant contains no conductive carbon.

3 . The automotive slide member according to claim 1 , wherein a content of the conductive carbon in the first lubricant is 0.01 mass % to 2 mass % with respect to a total mass of the first lubricant.

4 . The automotive slide member according to claim 3 , wherein the content of the conductive carbon in the first lubricant is 0.01 mass % to 0.5 mass % with respect to the total mass of the first lubricant.

5 . The automotive slide member according to claim 4 , wherein the content of the conductive carbon in the first lubricant is 0.01 mass % to 0.1 mass % with respect to the total mass of the first lubricant.

6 . The automotive slide member according to claim 1 , wherein a content of the conductive carbon in the second lubricant falls within a range of 0.1 mass % to 15 mass % with respect to a total mass of the second lubricant.

7 . The automotive slide member according to claim 6 , wherein the content of the conductive carbon in the second lubricant falls within a range of 0.5 mass % to 10 mass % with respect to the total mass of the second lubricant.

8 . The automotive slide member according to claim 7 , wherein the content of the conductive carbon in the second lubricant falls within a range of 2 mass % to 8 mass % with respect to the total mass of the second lubricant.

9 . The automotive slide member according to claim 1 , wherein the conductive carbon is selected from the group consisting of carbon black, carbon nanotube, carbon nanohorn, carbon nanofiber, graphene, and graphite.

10 . The automotive slide member according to claim 1 , wherein the second lubricant further contains polytetrafluoroethylene as the additive.

11 . The automotive slide member according to claim 1 , wherein each of the first lubricant and the second lubricant further contains a thickener, and is in a form of a grease composition.

12 . The automotive slide member according to claim 1 , wherein the automotive slide member is an electric power steering system.

13 . The automotive slide member according to claim 1 , wherein the automotive slide member is a steering column.

14 . The automotive slide member according to claim 1 , wherein the automotive slide member is a power window regulator.

15 . The automotive slide member according to claim 1 , wherein the automotive slide member is a brake caliper.

16 . The automotive slide member according to claim 1 , wherein the automotive slide member is an electric slide roof.

17 . The automotive slide member according to claim 1 , wherein the automotive slide member is an electric seat.

18 . The automotive slide member according to claim 1 , wherein the first slide portion and the second slide portion are provided in one member handled as a unit.
