Patent number: 10626641Abstract: A door check apparatus includes a base member configured to be attached to a vehicle door, a threaded rod rotatably held by the base member, a first tubular member including a distal end portion configured to be connected to a vehicle main body, and a base portion. The threaded rod is arranged inside the first tubular member. At least a part of the first tubular member threadedly engages with the threaded rod. The first tubular member performs a relative movement in an axial direction relative to the threaded rod such that the first tubular member causes the threaded rod to rotate. The door check apparatus includes a brake mechanism configured to restrict the threaded rod from rotating.Type: GrantFiled: November 5, 2018Date of Patent: April 21, 2020Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Takayuki Ueno, Masato Abe, Dai Hidaka, Hirokazu Suzumura
