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 only to the first ring amongst the first ring and the second ring and the other end of which being connected as a terminal to a rotor coil;
• a short-sized lead, one end of which being connected only to the second ring amongst the first ring and the second ring and the other end of which being connected as a terminal 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 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 bent lead portions respectively are between the linear lead portions and the terminals;
• 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 long-sized lead is disposed at a predetermined position in the molded body in such a state that a tension is imparted to the linear lead portion by the first ring and the lead support portions, and the short-sized lead is disposed at a predetermined position in the molded body in such a state that a tension is imparted to the linear lead portion by the second ring and the lead support portions.
