Derailleur for human-powered vehicle
A derailleur basically includes a base member, a movable member, a linkage assembly, a power source receiving part and a cover member. The power source receiving part is provided to at least one of the base member, the movable member and the linkage assembly. The power source receiving part receives a power source. The cover member is movable in a first direction to switch from a cover detachment state and a cover attachment state in which the cover member at least partially covers the power source receiving part. The cover member includes first and power source contact surfaces. The first power source contact surface contacts the power source in a holding state where the power source is held in the power source receiving part. The second power source contact surface contacts the power source during an operation for moving the cover member in the first direction.
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;
a movable member movably arranged relative to the base member; and
a linkage assembly movably connecting the base member and the movable member;
a power source receiving part provided to at least one of the base member, the movable member and the linkage assembly, the power source receiving part being configured to allow for arrangement of a power source;
a power source holder including an electric terminal, and arrangeable in the power source receiving part; and
a cover member configured move in a first direction to switch from a cover detachment state and a cover attachment state, the cover member at least partially covering the power source receiving part in the cover attachment state, the cover member including a first power source contact surface and a second power source contact surface,
the first power source contact surface being configured to contact the power source in a holding state where the power source is held in the power source receiving part,
the second power source contact surface being configured to contact the power source during an operation for moving the cover member in the first direction.
2. The derailleur according to claim 1 , wherein
the power source receiving part is provided to the linkage structure.
3. The derailleur according to claim 2 , wherein
the linkage assembly includes an inner link member and an outer link member, and
the power source receiving part is provided to the outer link member.
4. The derailleur according to claim 1 , wherein
the second power source contact surface includes an inclined surface inclined relative to the first power source contact surface.
5. The derailleur according to claim 1 , wherein
the first direction is a linear direction.
6. The derailleur according to claim 1 , wherein
the first direction is non parallel to an accommodating direction of the power source receiving part in which the power source is insertable in the power source receiving part.
7. The derailleur according to claim 6 , wherein
the linkage assembly includes an inner link member and an outer link member, and
the accommodating direction is parallel to a pivot axis of the outer link member.
8. The derailleur according to claim 1 , wherein
the second power source contact surface is configured to contact the power source as the cover member moves in the first direction, and is configured to move the power source in an accommodating direction of the power source receiving part to bring the power source into contact with the connection terminal as the cover member moves in the first direction.
