Abstract

A derailleur basically includes a base member, a movable member and a linkage assembly. The base member includes a first base member connecting section and a second base member connecting section. The movable member includes a first movable member connecting section and a second movable member connecting section. The linkage assembly includes an inner link member and an outer link member. The outer link is pivotally coupled to the second base member connecting section about a third pivot axis. The outer link is pivotally coupled to the second movable member connecting section about a fourth pivot axis. The outer link member has a power source receiving part that is configured to be arranged such that the power source receiving part traverses a reference line extending between the third pivot axis and the fourth pivot axis.

First claim

What is claimed is:

1. A derailleur for a human-powered vehicle, the derailleur comprising:
a base member configured to be attached to a frame of the human-powered vehicle, the base member including a first base member connecting section and a second base member connecting section;
a movable member movably arranged relative to the base member, the movable member including a first movable member connecting section and a second movable member connecting section; and
a linkage assembly movably connecting the base member and the movable member, the linkage assembly including:
an inner link member having a first inner link end portion and a second inner link end portion; and
an outer link member at least partially overlying the inner link member as viewed in a direction facing toward the frame in a state where the base member is attached to the frame, the outer link member having a power source receiving part, a first outer link end portion, and a second outer link end portion;
the first inner link end portion being pivotally coupled to the first base member connecting section about a first pivot axis,
the second inner link end portion being pivotally coupled to the first movable member connecting section about a second pivot axis,
the first outer link end portion being pivotally coupled to the second base member connecting section about a third pivot axis,
the second outer link end portion being pivotally coupled to the second movable member connecting section about a fourth pivot axis, and
the power source receiving part being configured to be arranged such that the power source receiving part traverses a reference line extending between the third pivot axis and the fourth pivot axis.

2. The derailleur according to claim 1 , wherein:
as viewed in a direction parallel to at least one of the third pivot axis and the fourth pivot axis, one part of a region divided by the reference line defines a first region and the other part of the region divided by the reference line defines a second region; and
the power source receiving part includes a portion located in the second region and a portion located in the first region that is larger than the portion located in the second region.

3. The derailleur according to claim 1 , wherein:
as viewed in a direction parallel to at least one of the third pivot axis and the fourth pivot axis, one part of a region divided by the reference line defines a first region and the other part of the region divided by the reference line defines a second region; and
the power source receiving part includes a portion located in the second region and a portion located in the first region that is smaller than the portion located in the second region.

4. The derailleur according to claim 1 , further comprising:
a power source holder including an electric terminal, and arrangeable in the power source receiving part,
the power source holder being configured to traverse the reference line in a state arranged in the power source receiving part.

5. The derailleur according to claim 1 , wherein:
the base member includes a base member attachment portion pivotally attached to the frame of the human-powered vehicle about an attachment portion pivot axis; and
the linkage assembly is configured to be arranged so that at least one of the first pivot axis, the second pivot axis, the third pivot axis, and the fourth pivot axis is orthogonal to the attachment portion pivot axis.

6. The derailleur according to claim 1 , wherein:
the base member includes a base member attachment portion pivotally attached to the frame of the human-powered vehicle about an attachment portion pivot axis; and
at least one of the first pivot axis, the second pivot axis, the third pivot axis, and the fourth pivot axis is inclined relative to a direction orthogonal to the attachment portion pivot axis.

7. The derailleur according to claim 1 , wherein
the power source receiving part includes an accommodation portion configured to accommodate a power source.

8. The derailleur according to claim 1 , further comprising:
a cover member at least partially covering the power source receiving part.

9. The derailleur according to claim 8 , wherein
the cover member is configured to traverse the reference line in a cover attachment state where the cover member at least partially covers the power source receiving part.

10. The derailleur according to claim 8 , wherein
the cover member is pivotally attached to the outer link member.

11. The derailleur according to claim 1 , wherein
the cover member is attached in a detachable manner to the outer link member.

12. The derailleur according to claim 11 , wherein
the cover member is press-fitted in a detachable manner to the outer link member.

13. The derailleur according to claim 11 , wherein:
the cover member includes a first rail;
the outer link member includes a second rail; and
the first rail is configured to slide on the second rail.

14. The derailleur according to claim 1 , wherein
the power source receiving part is formed integrally with the outer link member.

15. The derailleur according to claim 1 , wherein
the power source receiving part is formed separately from the outer link member.

16. The derailleur according to claim 15 , wherein
the power source receiving part includes a material differing from that of the outer link member.
