To provide the support structure of a motor shaft capable of defining the axial position of the motor shaft for the housing.SOLUTION: The support structure of a motor shaft includes a convex formed on the outer boundary of the motor shaft, a first bearing placed between the axial one side of the convex and the housing, magnetic steel sheets placed on the other side of the convex in the axial direction, and laminated in the axial direction, a second bearing placed between the other side of the magnetic steel sheets in the axial direction and the housing, and a snap ring for regulating relative movement of the second bearing and the housing in the axial direction. The motor shaft is positioned in the axial direction, by the axial pressure of the snap ring pushing the first bearing to the housing via the second bearing, the magnetic steel sheet and the convex.SELECTED DRAWING: Figure 2

    【課題】 ハウジングに対してモータシャフトの軸方向位置を規定可能なモータシャフトの支持構造を提供すること。【解決手段】本発明のモータシャフトの支持構造では、モータシャフトの外周に形成された凸部と、凸部の軸方向一方側とハウジングとの間に配置された第1ベアリングと、凸部の軸方向他方側に配置され、軸方向に積層された電磁鋼板と、電磁鋼板の軸方向他方側とハウジングとの間に配置された第2ベアリングと、第2ベアリングとハウジングとの軸方向の相対移動を規制するスナップリングと、を備え、モータシャフトは、スナップリングの軸方向与圧が、第2ベアリング,電磁鋼板及び凸部を介して第1ベアリングをハウジングに押し付けることで、軸方向に位置決めされる。【選択図】 図2
