顕著なるものである。As described above, according to the vibration isolator of the connecting member in the throttle valve link device of the multiple carburetor according to the present invention, the throttle valve for controlling the opening and closing of the intake passage in the intake passage penetrating the carburetor body. In the multiple carburetor provided with a throttle valve link device in which a plurality of carburetors are arranged and a throttle valve lever of each carburetor that rotates synchronously with the throttle valve of each carburetor is connected by a connecting member. Since the cylindrical roller having a ring groove formed on the outer periphery is rotatably arranged on a single carburetor body constituting a multiple carburetor, and the connecting member is slidably guided in the ring groove, the engine Even if it receives vibration, the connecting member can completely suppress the vibration by the roller,
There is no need to increase the rigidity of the connecting member, which can reduce the size of the synthetic resin material applied to the connecting member and the use of the metal material as compared with the conventional case, and make the entire vaporizer compact and lightweight. It was able to be. Further, wear due to vibration of the connecting portion between the throttle valve lever and the connecting member can be significantly reduced, and the degree of design freedom (selection of material, treatment, hardness) for this portion can be significantly improved. Also, according to the use of a cylindrical roller as a shake preventing member, and the roller is rotatably arranged on the carburetor body,
When the connecting member moves in the connecting direction, the roller rotates. According to this, the sliding resistance of the roller during the movement of the connecting member can be reduced, and the operation load of the operation wire can be prevented from increasing. These effects are particularly remarkable in the throttle valve link device of the multiple carburetor in which the connecting pitch of the adjacent carburetors is large and the length of the connecting portion in the connecting direction is long.
