Abstract

See full text

A shaft configured to suppress damage without having an increased diameter is provided. The shaft includes a supported portion supported by a bearing and an adjacent large-diameter portion larger in diameter than the supported portion and disposed closer to a center in an axial direction than the supported portion. The shaft is configured to rotate integrally with a rotor while holding the rotor. A sectional shape of a boundary portion between the supported portion and the large-diameter portion in a longitudinal section of the shaft is an arc shape that is, on an outer side in the axial direction with respect to a virtual rising point, recessed inward from an outer edge in the radial direction of the supported portion and raised outward in the radial direction from the outer edge, as the arc shape extends from the outer to an inner side in the axial direction.
