<p>PURPOSE:To dispense with a drop lifter unit by attaching a parting rail part, formed in an intersectional part at each rail, to a movable member, and connecting one of the parting rail parts to the corresponding rail by means of a movement of the movable member. CONSTITUTION:A right sub route 30 is installed in place along a main route 15, while a left sub route 40 is branched off from this right sub route 30, and this left sub route 40 is clossing aslant the main route 15 in plan view and then it goes along the opposite side of this main route 15. A part being situated in a clossing part between a first rail and a third rail 41 formed into parting rail parts 1A, 41A, and these parts are attached to a common movable member 25. With a movement of the movable member 25, one of the parting rail parts 1A, 41A is constituted so as to be connected to corresponding rails 1, 41. At this time, residual parting rail parts are in a noncontact state, and with a variation in a moving position of the movable member 25, these residual parting rail parts come into a state of being connected with each other.</p> |
