PURPOSE: To improve the operation of a carrier by more effectively passing through a cross section of a track or a folding section at a right angle when a panel is specially heavier. CONSTITUTION: A multi-directional carrier is constituted of a track and first and second ledges 18 and 22. Then, the ledges 18 and 22 are provided at an interval in the vertical direction and in the horizontal direction. Then, first and second discs 24 and 26 are borne on a bolt at an interval in the vertical direction. One disc 24 engages one ledge 18 on one side of the bolt, and the other disc 26 engages the other ledge 22 on the other side of the bolt. The underside of each of the discs 24 and 26 has an angled surface, and the upper side of each of the ledges 18 and 22 has a complementary angled surface which is engaged by one of the disc angled surfaces. The angles of both disc and ledge surfaces are substantially equal, being in the range of 2 deg.-8 deg. to the horizontal direction. |
