To provide a yoke integrated shaft having high welding quality.SOLUTION: A yoke integrated shaft includes a shaft one end of which points to a first direction and the other end of which points to a second direction, a yoke welded to one end of the shaft, and a welded part formed by welding the shaft and the yoke, the yoke including an annular base part having a through-hole passing therethrough in an axial direction parallel to the axis of the shaft, and a pair of arms protruded from the base part in the first direction, the shaft having a fitted part located at one end of the shaft and inserted into the through-hole of the base part, and a shaft part extending from the fitted part in the second direction, the fitted part having at least two first protrusions protruded from around the axis to the radial outside, the shaft part having second protrusions continuous with the first protrusions in the axial direction and having the same number as the first protrusions. A space between the first protrusions neighboring each other in a peripheral direction is a communication hole extending in the axial direction and communicating a space in the first direction of the base part with a space in the second direction.SELECTED DRAWING: Figure 10

    【課題】高い溶接品質を有するヨーク一体型シャフトを提供する。【解決手段】ヨーク一体型シャフトは、一端が第1方向を指し、他端が第2方向を指すシャフトと、シャフトの一端と溶接されるヨークと、シャフトとヨークとを溶接して生成された溶接部と、を備え、ヨークは、シャフトの軸と平行な軸方向に貫通する貫通孔を有する環状体の基部と、基部から第1方向に突出する一対のアームと、を備え、シャフトは、シャフトの一端に位置し、基部の貫通孔に挿入される嵌合部と、嵌合部から第2方向に延びる軸部と、を有し、嵌合部は、軸を中心に径方向外側に突出する少なくても2つ以上の第1突起を有し、軸部は、第1突起と軸方向に連続し、第1突起と同数の第2突起を有し、周方向に隣り合う第1突起同士の間の空間は、軸方向に延在し、かつ基部の第1方向の空間と第2方向の空間を連通させる連通穴となっている。【選択図】図10
