Patent number: 7971913Abstract: A base member is fixed to a rear surface of a door panel for a vehicle. A grip member is supported on the base member in a tiltable manner. The grip member is arranged on the base member from a front surface of the door panel. A pivot shaft is arranged on the grip member. A shaft supporting member supports the pivot shaft with respect to the base member so that the pivot shaft can pivot relative to the base member. As a result, the grip member is ensurely prevented from becoming loose with respect to the base member in a longitudinal direction of the grip member.Type: GrantFiled: July 21, 2005Date of Patent: July 5, 2011Assignee: Aisin Seiki Kabushiki KaishaInventors: Shigeyuki Sunahara, Tetsurou Tanimoto, Koichi Nagata
