Abstract
A balance weight for a two-wheeled vehicle includes a weight made from iron and a clip made from spring steel. The weight includes a first axial end, a second, opposite axial end, a transversely extending intermediate surface, and a first laterally extending groove for holding the clip therein having a groove bottom portion and a groove inlet portion which is smaller in width than the groove bottom portion. The clip includes a pair of arms, a connecting portion, an engaging portion formed in the connecting portion, a bent portion bent from the connected portion toward a space between the pair of arms, and an obliquely extending portion extending obliquely in a direction away from the transversely extending intermediate surface of the weight.

A balance weight for a two-wheeled vehicle comprising:
- a weight made from iron;
- and
- a clip made from spring steel,
- said weight including:
- an outside surface;
- a first axial end;
- a second, opposite axial end;
- a transversely extending intermediate surface located between said first end and said second end;
- a first axially extending portion located between said first end and said intermediate surface;
- a second axially extending portion located between said second end and said intermediate surface;
- a first laterally extending groove for holding said clip, formed in said first axially extending portion and having a groove bottom portion and a groove inlet portion smaller in width than said groove bottom portion, said first laterally extending groove holding said clip;
- and
- a second laterally extending groove formed in said second axially extending portion so as to recede from said outside surface,
- said clip including:
- a pair of arms;
- a connecting portion connecting said pair of arms and disposed within and held by said first laterally extending groove;
- an engaging portion formed in said connecting portion and raised in a direction opposite to said pair of arms;
- a bent portion connected to said connecting portion at one width end proximate to said transversely extending intermediate surface of said weight and bent from said one width end toward a space between said pair of arms;
- and
- an obliquely extending portion connected to said bent portion and extending obliquely in a direction away from said transversely extending intermediate surface of said weight;
- wherein when said balance weight is mounted to the two-wheeled vehicle, said pair of arms and said obliquely extending portion of said clip elastically hold a nipple of a spoke of the two-wheeled vehicle whereby said clip is fixed to the nipple, and said first laterally extending groove holds said clip and said engaging portion is pressed to said weight whereby said weight is fixed to said clip.
