摘要
An erroneous operation prevention mechanism 40 for forming a forward/backward switching lever 14 for switching forward/backward operation on the operation handle 8, and for restraining switching to the reverse position by operation of the forward/backward switching lever 14 Is formed on the same side of the operation handle 8, the accelerator lever 15 for adjusting the rotational speed of the engine 3 is formed, and by operating the forward/backward switching lever, the accelerator lever position maintenance release and forward/backward switching are performed. The accelerator is interlocked with the reverse operation of the forward/backward switch lever 14 between the forward/backward switching lever 14 and the accelerator lever 15 so as to enable and to prevent the reduction of the operating load and the misoperation of the reverse operation. An interlocking mechanism 30 for moving the lever 15 to a low speed side is formed, and in the interlocking mechanism 30, an interlocking range α in which the operation of the forward/reverse switching lever 14 interlocks with the accelerator lever 15 is provided. And, the operation of the forward/backward switching lever 14 operates the forward/backward switching device 28, but forms a non-interlocking range β that does not interlock with the accelerator lever 15.
