A step device for a vehicle includes a movable step supported under a door opening, and a coupling member supported by a sliding door that opens and closes in a vehicle front-rear direction with a shifting zone in a vehicle width direction. The movable step is provided with a guide rail that opens downward and extends in the vehicle front-rear direction. The coupling member includes: a fixed member fixed to the sliding door; an arm member coupled to the fixed member; a guide roller disposed inside the guide rail; and an urging member configured to apply to the arm member an urging force in a direction in which the guide roller turns upward.

Step device for vehicle

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 step device for a vehicle includes: a movable step supported under a door opening; a coupling member that, in a state of being supported by a sliding door, engages with the movable step to move the movable step in a vehicle width direction in conjunction with opening and closing of the sliding door; a support arm that has a first pivot-joint point relative to a vehicle body and a second pivot-joint point relative to the movable step, and supports the movable step toward an upper side; and a pressure bearing member that is provided at a position between the first pivot-joint point and the second pivot-joint point and bears the load of the support arm by coming into sliding contact with the support arm.

A step device for a vehicle includes: a movable step supported under a door opening; a coupling member that moves the movable step in a vehicle width direction in conjunction with opening and closing of a sliding door; and a sub-step that is disposed under the door opening. The movable step moves under the sub-step toward an outer side in the vehicle width direction so as to be disposed in a deployed position in which the movable step protrudes from the sub-step toward the outer side in the vehicle width direction. The sub-step has an overlapping region that covers an upper side of the movable step in a state where the movable step is disposed in the deployed position.
