前後進切換え操作構造。 The operating path S of the operating lever 13 is divided into a first operating path S1 that goes forward from the front-rear intermediate operating position N, and a second operating path S2 that goes rearward from the intermediate operating position N.
and a horizontal path S3 connecting both paths S1 and S2 at the intermediate operating position N , and the forward state is changed by operating the horizontal path S3 toward the first operating path S1 . , the operating lever 13 and the forward/reverse switching mechanism C are interlocked and connected so that the operation toward the second operating path S2 brings about the reverse state, and the main clutch 8 is disengaged at the intermediate operating position N of the operating lever 13. The operating lever 13 and the biased main clutch 8 are connected via the cam mechanism B so that the main clutch 8 is engaged and operated by either forward or backward operation from the intermediate operating position N. The cam mechanism B is configured such that the main clutch operation reaction force applied to the operation lever 13 through the cam mechanism B acts more on the second operation path S2 than on the first operation path S1. Operation structure for switching forward and backward movement of a walk-behind work machine.
