Claims

[Scope of utility model registration request]

A handle 2 attached to the fuselage 1 is installed so that the direction in which it extends from the fuselage can be changed by rotating it around the vertical axis P, and the left and right grip portions 3, 4 of the handle 2 are
The operating side wires 7 and 8 connected to the left and right operating levers 5 and 6 are connected to the operating side part 9 of the switching case 11 consisting of two relatively rotatable parts, and extend from the left and right driven parts of the fuselage 1 side. Actuation side wire 12
, 13 are connected to the operating side part 10 of the switching case 11, and both the parts 9, 1 in the switching case 11
In an agricultural machine in which the connection between the operation side wires 7, 8 and the actuation side wires 12, 13 is reversed left and right due to the relative rotation of 0, the vertical axis center P
A partial gear 14 centered on is fixed to the body 1 side, and a driven gear 15 that can mesh with this partial gear 14 is rotatably mounted on the handle 2 side,
The driven gear 15 and the operating side part 10 of the switching case are interlocked and connected by a spring joint 16, so that the operating side part 10 of the switching case 11 is automatically rotated by the rotational force of the driven gear 15 when the steering wheel is turned. An operating wire switching device for an agricultural working machine, characterized in that the connection relationship between the operating side wire and the actuating side wire is reversed left and right.
