A door suspension device (5A) includes a driving-side member (21), a hanger (26), an elastic member (24), pressed door rollers (52, 72), and linking mechanisms (53, 73). The driving-side member (21) is displaceable in an opening/closing direction X when a drive force is imparted from an opening/closing drive mechanism (6). The hanger (26) is displaced in conjunction with a displacement of the driving-side member (21) and supports a door (2). The elastic member (24) allows relative displacements of the driving-side member (21) and the hanger (26) by elastically deforming in accordance with a load that acts between the driving-side member (21) and the hanger (26). The linking mechanisms (53, 73) convert a relative displacement operation of the driving-side member (21) and the hanger (26) into an operation in which the pressed door rollers (52, 72) are pressed against an upper rail (44). |
