A carriage (10) provided with one or more pairs of wheels (14) for moving sliding door (42) is arranged in a sliding seat (44) of an extruded profile (28), made of aluminium or other suitable material and fixed to a wall (48) or ceiling (54). The extruded profile in which the carriage (10) is arranged comprises opposite side walls (30, 32), oriented orthogonally with respect to the upper base (34) and with respect to the lower base (36) of said profile; on said lower base a central slot (38) extending longitudinally is made for the passage of a stem (40) projecting downwards in the direction of the door (42) to which it is connected. The carriage (10) comprises a support body (12) made of plastic, metal or other suitable material, constituting the load-bearing frame of said carriage to which the pairs of wheels (14) are connected, with rivets (16); each of the wheels is paired with an elastic element (20) placed in a recess (24) made along the opposite sides of the support body (12).

A roller assembly for a sliding vehicle door includes a bracket structure having a first and second inner horizontal guide roller arranged to interact with an inner vertical surface of the track member. The bracket structure further includes at least a first and second vertical guide roller arranged to interact with a first inner surface of the track member, a resiliently arranged rotatable member arranged to interact with a second inner surface of the track member and at least one outer horizontal guide roller arranged to interact with an outer vertical surface of the track member.

A drive device comprises a housing, a drive portion, a spindle member to rotate by driving of the drive portion, a nut member screwed with the spindle member); a moving member coupled to the nut member, and a rotation regulating portion which suppresses rotation of the nut member to move the nut member) in an axis X direction of the spindle member, wherein the moving member has a fragile portion to be broken by a predetermined force being weaker than a force required to break the nut member, and the fragile portion is configured that a fracture portion with which the nut member is pressable by the moving member toward the drive portion is formable when the fragile portion is broken.
