Abstract
When a sliding door (3) as a plate-like object is moved in a front and rear direction from a closed position to an opening preparation position, a rotatable rail (20) rotates from a horizontal lying position to a vertical standing position about a rotation axis (L1). When the sliding door is in the opening preparation position, a roller (40) of the sliding door (3) rides on a running track (25b) of the rotatable rail (20). When the sliding door (3) is further moved from the opening preparation position to an open position, the roller (40) transfers from the running track (25b) to an auxiliary track (26) of an adjacent rotatable rail (20). The rotatable rail (20) is biased toward the standing position by an elastic force of a torsion spring (18) and maintained in the standing position by an arm (13). This allows the sliding door (3) to be returned to the opening preparation position.
