Starter with thermal insulation cover

A starter comprising:

• a yoke forming a magnetic path for a starter motor;
• a housing and an end frame attached to respective axial end sides of the yoke and forming a starter frame together with the yoke, the starter frame having a yoke-side part of the housing and a yoke-side part of the end frame;
• a thermal insulation cover surrounding an outer peripheral surface of the starter frame;
• and
• at least one elastic member, made of a material more elastic than a material from which the thermal insulation cover is made, disposed between the starter frame and the thermal insulation cover and supporting the thermal insulation cover to be radially spaced apart from the starter frame;
• wherein said at least one elastic member includes two elastic members respectively fitted at first and second locations axially spaced away from each other;
• the first location is one of an abutting portion between the housing and the yoke and a housing portion axially outside the yoke;
• the second location is one of an abutting portion between the yoke and the end frame and an end frame portion axially outside the yoke;
• the thermal insulation cover has a central part located around the yoke and a first axial end part located around the first location;
• an inner diameter of the central part is smaller than that of the first axial end part;
• and
• an outer diameter of the elastic member is larger than the inner diameter of the first axial end part.

• two elastic members disposed between the starter frame and the thermal insulation cover and supporting the thermal insulation cover to be radially spaced apart from the starter frame,
• wherein the elastic members each have a ring shape, are fitted circumferentially around the starter frame and are in tight contact with the outer peripheral surface of the starter frame and an inner peripheral surface of the thermal insulation cover,
• the elastic members are respectively fitted at first and second locations axially spaced away from each other,
• the first location is one of an abutting portion between the housing and the yoke and a housing portion axially outside the yoke,

• a thermal insulation cover surrounding an outer peripheral surface of the starter frame, the thermal insulation cover having a radially enlarged part at an axial end thereof;
• and
• at least one elastic member disposed between the starter frame and the thermal insulation cover at a position radially inward of the enlarged part and supporting the thermal insulation cover to be radially spaced apart from the starter frame.
