[Effect of this invention]

According to the present invention as described above, due to the fact that the clutch is turned off by the steering clutch lever due to the turning from the non-head side, the operation of the clutch is turned off automatically. Since it is not necessary, and the turning is smooth and decelerated at speed, the steering wheel can reduce the turning area of the head without holding the steering wheel.

In addition, the work clutch lever has the following distinctive working effects, resulting in the basic working effect that does not interfere with the work precision, for example, the transition to the working state after turning, due to the fact that it can be operated independently.

Since the interlocking member of the interlocking mechanism swings on the rear inclined plane in the crosswise direction of the support lever, even if the interlocking member is enlarged, it can be designed compactly, and the operation amount of the operating lever is minimal. In addition, since the joint member intersects with the interlocking member and depends on the longitudinal direction of the support lever, the joint member can be compactly designed so that the connection wire and the like can be connected without difficulty.
