An overhead conveyor comprising a main rail, right and left two auxiliary rails arranged on the opposite sides of the main rail and positioned at a higher level in an upward slope section of the conveyor line and at a lower level in a downward slope section of the conveyor line, relative to their immediately previous horizontal position based on the main rail, a main running body forwardly movable along the main rail, auxiliary running bodies forwardly movable along the auxiliary rails following the main running body, and a front suspender and right and left rear suspenders connecting the main running body and the auxiliary running bodies to a hanger support positioned below the running bodies. The front and rear suspenders are pivotally movable forward and rearward and horizontally turnable. One of the rear suspenders comprises a forward-rearward pivotable member and a sidewise pivotable member connected to the lower end thereof. In a curved section, the main rail and the auxiliary rails are arranged on arcs of three concentric circles.
