Patent ID: 6858966

Claim:
A slip ring apparatus for an automotive alternator, comprising, a pair of slip rings electrically insulated from each other and disposed coaxially; a pair of electric conductive elements for providing electric connection between said pair of slip rings and a field coil of said automotive alternator; and an insulating member for holding said pair of slip rings and said pair of electric conductive elements, wherein said pair of electric conductive elements have at least one deformation absorbing portion for absorbing a deformation of said pair of electric conductive elements, one electric conductive element is connected to one slip ring located far from said field coil compared with the other slip ring, and is disposed at a radially inner side of said other slip ring with an insulating gap provided between said one electric conductive element and said other slip ring, and said at least one deformation absorbing portion is formed on said one electric conductive element.
