Patent number: 6886426Abstract: In a shift lever apparatus, a shift position can be changed from a āPā shift position only by turning a shift lever to a right side of a vehicle. Unless a brake is operated, it is possible to maintain a state in which a stopper portion is disposed in a right side of the vehicle in an abutting portion. Therefore, the abutting portion abuts the stopper portion, and the shift lever cannot be turned to the right side of the vehicle. When the brake is operated, a rotary plate is rotated in accordance that the shift lever turns to the right side of the vehicle. Accordingly, the abutting portion does not abut the stopper portion, and the shift lever can be turned to the right side of the vehicle.Type: GrantFiled: October 23, 2002Date of Patent: May 3, 2005Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventor: Keiji Kahara
