A step device for a vehicle includes a movable step and a coupling member. The movable step includes a guide rail. The coupling member is configured to cause the movable step to move from a deployed position to a retracted position as a engaging part comes into sliding contact with a side wall of the guide rail that is located on an inner side in a vehicle width direction and, while pressing the side wall, moves inside the guide rail in a direction of closing a sliding door. The guide rail is configured such that a terminal end region on a closing side including a terminal end position at which the engaging part is located when the sliding door is fully closed constitutes a closing-side free running zone in which the engaging part does not press either of the side walls.

A vehicle includes a frame, and at least one front and rear wheel. The total number of front and rear wheels is at least three. The vehicle includes a mechanism for driving at least one of the front and rear wheels, a seat for a driver, and at least one fall prevention element to prevent, in a closed position of the fall prevention element, a driver from falling off the seat. In an open position of the fall prevention element, a driver can freely take a seat from the outer side of the vehicle via the space which, in the closed position, is occupied by the fall prevention element, or can step out of the vehicle; the fall prevention element slides between the open and closed positions.

A hold lock mechanism for a vehicle door, the hold lock mechanism including a grip assembly configured to be mounted on a vehicle body, the grip assembly including a pair of grip members configured to releasably grip a door component and a hook provided on at least one of grip members, and a release assembly mounted on the door component, the release assembly including a release member configured to releasably engage with the hook.

A motor vehicle includes a ramp, a sliding door that when open allows the ramp to be deployed from the vehicle, and an anti-rattle device to prevent or reduce rattling of the ramp against the door or other components of the vehicle when the ramp is in a stowed position. The anti-rattle device includes an arm pivotable relative to the door and a roller rotatably coupled to the arm, spaced apart from the door, and configured to contact the ramp.

A structure for preventing opposite sliding doors from swaying is provided. The structure includes a lower rail mounted in a longitudinal direction at a lower side of a vehicle body, a lower rail roller unit rollably connected to the lower rail, a lower rail swing arm rotatably connected to the lower rail roller unit and a door, a guide roller unit fixedly connected to the lower rail, the guide roller unit including a guide roller rotatably connected to the lower rail, and a guide stopper fixedly connected to the door. The guide stopper includes a guide route formed inside the guide stopper and configured to serve as a rolling movement route for the guide roller, an exit/entrance portion formed at a first end of the guide route, and a stop portion formed at a second end of the guide route.

A guide rail includes: a first rail that has a bottom wall on which a load roller rolls and supports the weight of a sliding door; a second rail that has side walls on which two guide rollers roll and defines a moving direction of the sliding door; and a first restriction part that restricts the motion of the load roller in an axial direction.
