1. A caster assembly for a vacuum cleaner casing, comprising:

  • a body member;

    means for mounting said body member on a substantially planar lower surface of said casing, said mounting means being arranged to allow pivoting movement of said body member relative to said casing about an axis transverse to said lower surface;

    a caster wheel rotatably mounted on said body member for rolling contact with a floor surface supporting said vacuum cleaner casing, the line of rotation of said caster wheel passing through said pivot axis, the rotational axis of said caster wheel being spaced from said pivot axis and substantially parallel to said lower surface; and

    a pair of idler wheels rotatably mounted on said body member for rolling contact with said lower surface of said casing, the axes of rotation of said idler wheels being equiangularly spaced on opposite sides of said caster wheel line of rotation and intersecting at said pivot axis;

    wherein the improvement comprises said body member being formed with an integral substantially planar extension beyond said caster wheel from said pivot axis, said extension being spaced from and substantially parallel to said lower surface so as to cooperate with the remainder of said body member to provide a wrap tongue for the electric line cord of the vacuum cleaner.
