<p><P>PROBLEM TO BE SOLVED: To prevent elevating/lowering of branching rollers from interfering with a guide rail, to eliminate need for deceleration in front of a branching part, and to travel on the branching part without any play at high speed in either branching or advancing straight. <P>SOLUTION: In a ceiling travel vehicle for switching between the branching and advancing straight by the elevating/lowering of the right and left branching rollers 22, 23, a gap is provided between a guide surface of the guide rail 56 and the branching rollers 22, 23 outside the branching part, and eliminated by expanding width of the guide rail in the branching part. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
