PROBLEM TO BE SOLVED: To transform a single spindle two-wheel or double spindle four-wheel head runner attached to a curtain rail into cross runner. SOLUTION: A cross runner (30) is formed by fixing a cross attachment (5) to a single spindle two-wheel or double spindle four-wheel head runner (4). The cross attachment (5) is equipped with a flat steering part (17) protruded upwards from the upper surface of the rear part, a guide wheel (18) pivotally supported for free rotation in contact with the back of the lower side of that steering part, a cross arm part (6) curved from the center to the front and next extended to the distal end, a hook hole (7) opened on the distal end of that arm part, fixing screw holes (26 and 26a) through the center and split sleeve parts (20) protruded from these fixing screw holes to the back side and inserted through the through hole of the top runner, and the attachment is fixed to the top runner (4) by fixing screws (24) screwed into these split sleeves.
