PROBLEM TO BE SOLVED: To provide a hub dynamo in which a dimensional variation of yokes can be absorbed so that no gap is formed on abutment surfaces between the yokes.SOLUTION: A first yoke 120A and a second yoke 120B are disposed on a plane (an actual arrangement surfaces SA1, SB1 of the yoke) inclined with respect to a radial direction (yoke arrangement reference surfaces SA0, SB0), and at an intersection line SC between the actual arrangement surface SA1 of the first yoke and the actual arrangement surface SB1 of the second yoke, a tip 123a of the inner peripheral magnetic pole portion 123 of the first yoke and the tip 123a of the inner peripheral magnetic pole portion 123 of the second yoke are abutted on each other.SELECTED DRAWING: Figure 12
【課題】ヨークの寸法的なバラツキを吸収することができて、ヨーク同士の当接面に隙間が生じないようにする。【解決手段】第1ヨーク120Aと第2ヨーク120Bを半径方向(ヨークの配置基準面SA0、SB0)に対して傾斜した平面(ヨークの実配置面SA1、SB1)上に配置し、第1ヨークの実配置面SA1と第2ヨークの実配置面SB1との交差線SC上において、第1ヨークの内周側磁極部123の先端123aと第2ヨークの内周側磁極部123の先端123aとを当接させた。【選択図】図12
