<P>PROBLEM TO BE SOLVED: To reduce moment load that acts on a turning support part for turnably supporting a branch guide roller when carrying out branch guide in a conveyance system. <P>SOLUTION: A branch guide roller mechanism 24 has branch guide rollers (36-39): a first movable arm 101 and a second movable arm 103 which support the branch guide rollers (36-39); and turning support parts 51 and 55 (turning support part) which turnably support the first movable arm 101 and the second movable arm 103 to a traveling vehicle. A branch guide roller driving mechanism 40 is prepared in a traveling vehicle and drives the branch guide roller style 24 in order to switch the branch guide rollers (36-39) to branch guide rail section 6e by a guide position and a non-guiding position. A height position of a turning center C of turning support parts 51 and 55 locate within a vertical direction width H1 of a part to which the branch guide rollers (36-39) can contact in the guide position in a branch guide rail section 6e. <P>COPYRIGHT: (C)2012,JPO&INPIT |
