Abstract

A sliding component comprises a base member, a plated layer, and a lubricant agent. The plated layer includes a metallic material and is disposed on the base member. The lubricant agent includes a fatty acid containing a carboxyl group. The lubricant agent contacts the plated layer.

First claim

What is claimed is:

1. A bicycle component comprising:
an outer member enclosing an internal space in which a lubricant agent including a fatty acid containing a carboxyl group is stored, the outer member being sealed so as to keep the lubricant agent in the internal space; and
a sliding component disposed within the internal space, the sliding component including:
a base member; and
a plated layer including a metallic material, the plated layer being disposed on the base member, the lubricant agent contacting the plated layer.

2. The bicycle component according to claim 1 , wherein
the fatty acid includes an olein acid.

3. The bicycle component according to claim 1 , wherein
the fatty acid includes a stearic acid.

4. The bicycle component according to claim 1 , wherein
the fatty acid includes a linoleic acid.

5. The bicycle component according to claim 1 , wherein
the plated layer has Vickers hardness ranging from 10 HV to 200 HV.

6. The bicycle component according to claim 1 , wherein
the plated layer includes tin.

7. The bicycle component according to claim 6 , wherein the sliding component includes
a chromized layer to slidably contact the plated layer.

8. A bicycle component comprising:
an outer member having an internal space; and
a sliding component disposed within the internal space, the sliding component including:
a base member;
a plated layer including a metallic material, the plated layer being disposed on the base member; and
a lubricant agent including a fatty acid containing a carboxyl group, the lubricant agent contacting the plated layer, wherein

the plated layer includes silver.

9. The bicycle component according to claim 8 , wherein the sliding component includes
a chromized layer to slidably contact the plated layer.

10. The bicycle component according to claim 1 , further comprising:
a bicycle chain disposed within the internal space and including the base member and the plated layer.

11. The bicycle component according to claim 10 , wherein
the bicycle chain includes an inner link plate and an outer link plate, and
at least one of the inner link plate and the outer link plate includes the base member and the plated layer.

12. The bicycle component according to claim 11 , wherein
the bicycle chain includes a pin which is chromized.

13. The bicycle component according to claim 12 , wherein
the inner link plate includes the base member and the plated layer, and
the pin is configured to slidably contact the inner link plate.

14. The bicycle component according to claim 1 , wherein
the bicycle component is a Bowden cable.

15. The bicycle component according to claim 14 , wherein
the Bowden cable includes an inner wire disposed within the internal space, and
the inner wire includes the base member and the plated layer.

16. The bicycle component according to claim 1 , further comprising:
a gear disposed within the internal space and including the base member and the plated layer.

17. The bicycle component according to claim 16 , wherein
the gear is a part of a bicycle drive train.

18. The bicycle component according to claim 1 , further comprising:
a planetary gear mechanism disposed within the internal space and including at least one planetary gear, at least one sun gear, and at least one ring gear, at least one of the at least one planetary gear, the at least one sun gear, and the at least one ring gear including the base member and the plated layer.

19. A sliding component comprising:
a base member;
a plated layer including silver, the plated layer being disposed on the base member; and
a lubricant agent including a fatty acid containing a carboxyl group, the lubricant agent contacting the plated layer.
