PURPOSE: To simplify the structure of a traveller and smoothly handle it by movably mounting a traveller car to which a main seat is connected on a traveller track and by preventing fittings such as pulleys or so from being crowdedly mounted at a focused point on the travel track.

CONSTITUTION: A traveller car 5 to which a main seat not illustrated is connected is widthwise and movably mounted on a traveller track 4. The traveller car 5 has flanges 52 which are longitudinally formed at both sides of a back plate 51 to which the main seat is to be attached. A pair of rollers 56 on which a side hall rope 6 is bound are mounted on each outer face of the flange 52. The side hall hope 6 for shifting the traveller car 5 is thereby easily handled so that the rope 6 is prevented from being entangled or caught to lock.
