Slip ring apparatus for electric rotating machine

A slip ring apparatus for an electric rotating machine, comprising:

• a first ring and a second ring being insulated from each other and disposed coaxially with each other;
• a long-sized lead one end of which being connected to the first ring and the other end of which being connected to a rotor coil;
• a short-sized lead one end of which being connected to the second ring and the other end of which being connected to the rotor coil;
• a restricting member configured to determine positions of the long-sized lead and the short-sized lead;
• and a molded body formed by insert molding and retaining the first ring, the second ring, the long-sized lead, the short-sized lead, and the restricting member, wherein:
• the long-sized lead and the short-sized lead respectively have linear lead portions disposed axially parallel to each other, and bent lead portions formed by bending the linear lead portions radially outward;
• and
• the restricting member has lead support portions each being in contact with at least a radially outward face of each of the bent lead portions of the long-sized lead and the short-sized lead, and the restricting member is to be disposed in a mold for the insert molding in such a state that the bent lead portions are brought into contact with the lead support portions respectively so as to impart a tension to the linear lead portions.
