Patent number: 9701218Abstract: In a case where an engagement member is assembled on an upper rail, a second rotary shaft portion is inserted to a shaft receiving bore of a first side wall portion from an inner side of an upper rail. After the insertion, the engagement member is rotated so that the second rotary shaft portion is inserted to the shaft receiving bore of the second side wall portion. At this time, because a shaft allowable length is specified to be greater than a shaft maximum rotation length, an interruption of an insertion of the rotary shaft portion because of a contact of the second rotary shaft portion with an edge portion of the shaft receiving bore at the second side wall portion is restrained.Type: GrantFiled: October 24, 2014Date of Patent: July 11, 2017Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Takanori Satoh, Koji Kumagai, Makoto Sakai, Yasuhiro Kojima
