Patent number: 11518312Abstract: 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.Type: GrantFiled: September 4, 2020Date of Patent: December 6, 2022Assignees: AISIN SEIKI KABUSHIKI KAISHA, TOYOTA SHATAI KABUSHIKI KAISHAInventors: Yoshihiro Oji, Keisuke Nomura, Shinji Kazama, Kazuhiro Hibi, Kazuhiro Ikeda
