PURPOSE:To prevent vibration transfer to a knob side by adhering and curing rubber between connection ends of two levers by using the cylindrical part of one lever and the rod-shaped part of the other as molds, and absorbing the vibration of a speed change gear side by the rubber. CONSTITUTION:A control lever 1 consists of an upper lever 2 and a lower lever 3 connected mutually; a cylindrical part 2a is formed at the connection end of one lever 2, and a rod-shaped part 3a is provided to the other lower lever 3. Those cylindrical part 2a and rod-shaped part 3a are used as molds to adhere and cure rubber 4 between the connection ends of the both. At the cylindrical part 2a, holes 10 and 11 are formed, a projecting part 12, a recessed part 13, and a through hole 14 are formed at right angles to the axial direction of the rod-shaped part 3a so that the hole 10 and projecting part 12 are opposed to each other, and a rod 15 extending into the hole 11 is engaged to the through hole 14. Then, the rubber 4 absorbs vibration of the lower lever 3 on a speed change gear mechanism side, preventing the transfer of the vibration to the knob side of the lever 2. |
