Claim:
A balance weight formed into a substantially columnar shape to extend in an axial direction of a spoke connecting a wheel hub and a rim of a spoke wheel, said balance weight comprising: a weight body having an insertion recess extending over its entire axial length to open in its outer periphery, whereby the balance weight is adapted to be secured by crimping to the spoke so as to surround the spoke inserted into the insertion recess, and a reduced section having a decreased diameter at an end of the balance weight facing toward the wheel hub when crimped to the spoke; wherein the reduced section has a length which is approximately one quarter of the entire axial length of the balance weight, and wherein the reduced section includes a tapered portion and a substantially cylindrical portion leading to a smaller-diameter end of the tapered portion; wherein the balance weight also comprises a main body portion and a rounded corner portion disposed between the reduced section and the main body portion, and said main body portion has a tapered shape with an outer diameter decreased toward the wheel hub and configured such that a taper of the main body portion is smaller than that of the tapered portion of the reduced section.
