PURPOSE:To remove fine vibration of levers and to prevent the generation of disturbance due to the vibration by abutting the end part of a restoration spring upon all spring receiving surfaces when both the levers are located on restorating positions and always applying exciting force to position both the levers. CONSTITUTION:When the 1st and 2nd levers 5, 6 are not operated at all, these levers are excited by a restoring spring 21 and located on the restoring positions. Under said state, the other end 23 of the spring 21 is located on the bottom of a trough 30 and excites both the spring receiving surface 12, 18 downwards. Consequently, the back of both the levers 5, 6 are kept at the state pressing to a stopper 29 and these levers 5, 6 are prevented from vibration to a base 1. Therefore, no fine vibration is generated in the levers 5, 6 even if an automobile is travelled under said state and the generation of disturbance is prevented. |
