Abstract

A bicycle component is provided that is capable of suppressing rattling against a frame. The bicycle component includes a housing, a first attaching part and an adjustment member. The housing is configured to rotatably support a crankshaft. The first attaching part is provided to the housing and configured to be attached to a frame. The adjustment member has at least a portion which is configured to be disposed in a gap that is formed between the first attaching part and the frame while in a state in which the first attaching part is attached to the frame.

First claim

What is claimed is:

1. A bicycle component comprising:
a housing configured to rotatably support a crankshaft;
a first attaching part coupled to the housing and configured to be attached to a frame; and
an adjustment member having at least a portion configured to be disposed in a gap that is formed between the first attaching part and the frame while in a state in which the first attaching part is attached to the frame, a length of the adjustment member in an axial direction of the crankshaft is larger than a smallest length of the gap between the first attaching part and the frame.

2. The bicycle component as recited in claim 1 , wherein
the adjustment member is a washer.

3. The bicycle component as recited in claim 2 , wherein
the first attaching part has a hole, and
the first attaching part is configured to be attached to the frame by a bolt that is disposed in the hole of the first attaching part.

4. The bicycle component as recited in claim 3 , wherein
the hole of the first attaching part includes a female thread that threadedly engages a thread of the bolt.

5. The bicycle component as recited in claim 3 , wherein
the bolt is dimensioned to be inserted in the washer.

6. The bicycle component as recited in claim 2 , wherein
the washer is a tapered washer.

7. The bicycle component as recited in claim 6 , wherein
the tapered washer has an elongated opening that extends in a tapering direction of the tapered washer.

8. The bicycle component as recited in claim 6 , wherein
the tapered washer has a first inclined surface that contacts one of the first attaching part and the frame.

9. The bicycle component as recited in claim 8 , wherein
the first inclined surface is textured to increase a friction resistance of the first inclined surface of the tapered washer.

10. The bicycle component as recited in claim 8 , wherein
the first attaching part has a second inclined surface that contacts the first inclined surface of the tapered washer.

11. The bicycle component as recited in claim 10 , wherein
the second inclined surface is textured to increase a friction resistance of the second inclined surface of the first attaching part.

12. A bicycle component comprising:
a housing configured to rotatably support a crankshaft;
a first attaching part coupled to the housing and configured to be attached to a frame; and
an adjustment member having at least a portion configured to be disposed in a gap that is formed between the first attaching part and the frame while in a state in which the first attaching part is attached to the frame, the adjustment member is being adjustably supported to the first attaching part to change a protrusion amount of the adjustment member from the first attaching part.

13. The bicycle component as recited in claim 12 , wherein
the adjustment member has one of a male thread and a female thread, and
the first attaching part has the other of the male thread and the female thread, which is coupled to the one of the male thread and the female thread of the adjustment member.

14. The bicycle component as recited in claim 13 , wherein
the first attaching part includes a supporting portion which has a male thread on an outer peripheral, and
the adjustment member includes a nut having a female thread.

15. The bicycle component as recited in claim 12 , wherein
the first attaching part has a hole, and
the first attaching part is configured to be attached to the frame by a bolt that is disposed in the hole.

16. The bicycle component as recited in claim 15 , wherein
the adjustment member has a hole in which the bolt can be inserted.

17. The bicycle component as recited in claim 15 , wherein
the hole of the first attaching part includes a female thread that threadedly engages a thread of the bolt.

18. The bicycle component as recited in claim 12 , wherein
the first attaching part has an insertion bore, and
the adjustment member is press-fitted into the insertion bore of the first attaching part.

19. The bicycle component as recited in claim 18 , wherein
the adjustment member has a hole, and
the first attaching part is configured to be attached to the frame by a bolt that is disposed in the hole of the adjustment member.

20. The bicycle component as recited in claim 19 , wherein
the bore of the adjustment member includes a female thread that threadedly engages a thread of the bolt.

21. The bicycle component as recited in claim 18 , wherein
the adjustment member has an outer periphery with a suppression portion that suppresses movement of the adjustment member relative to the first attaching part.

22. The bicycle component as recited in claim 21 , wherein
the suppression portion includes knurling that is formed on the outer periphery of an adjustment member.

23. The bicycle component as recited in claim 18 , wherein
the insertion bore of the first attaching part has a first portion to which the adjustment member is press-fitted, and a second portion having a smaller inner diameter than an inner diameter of the first portion, the second portion has a female thread.

24. The bicycle component as recited in claim 23 , wherein
the adjustment member has a bore,
the first attaching part is configured to be attached to the frame by a bolt that is disposed in the bore of the adjustment member,
the inner diameter of the second portion is smaller than an inner diameter of the bore of the adjustment member, and
the second portion has a female thread within the bore of the adjustment member when viewed from an axial direction of the bolt.

25. The bicycle component as recited in claim 1 , further comprising:
a second attaching part provided to the housing and configured to be attached to the frame in a position that is different from the first attaching part with respect to a direction parallel to an axis of the crankshaft.

26. The bicycle component as recited in claim 25 , wherein
at least a portion of the adjustment member is disposed on an opposite side of the second attaching part relative to the first attaching part with respect to the direction parallel to the axis of the crankshaft.

27. The bicycle component as recited in claim 25 , wherein
the housing rotatably supports an output rotating body which is disposed outside the housing and which transmits rotation of the crankshaft to a rear wheel, and
the second attaching part is provided closer to the output rotating body than the first attaching part with respect to the direction parallel to the axis of the crankshaft.

28. The bicycle component as recited in claim 1 , further comprising:
a motor that assists a manual drive force that is applied to the crankshaft.

29. The bicycle component as recited in claim 1 , further comprising:
a transmission that changes a transmission ratio of a bicycle.

30. A bicycle component comprising:
a housing configured to rotatably support a crankshaft;
a first attaching part coupled to the housing and configured to be attached to a frame; and
an adjustment member having at least a portion configured to be disposed in a gap that is formed between the first attaching part and the frame while in a state in which the first attaching part is attached to the frame, the adjustment member having a holding portion that is held by the first attaching part, and
