FIELD: domestic equipment. SUBSTANCE: apparatus has vertical electric cord coil spindle, spherical movable members, positioned in coil hub channels, and fixed member formed as cylindrical rim embraced by hub. Cylindrical rim surfaces are provided with depressions faced toward coil channels. Hub channel axes are positioned at an angle to horizontal plane. One side of each depression in cylindrical rim makes continuation of hub channel side, other side is positioned at an angle with respect to one side. Depth of depression is less than half diameter of spherical member. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. |
