Claims

[Scope of utility model registration request]

The operating shaft 44 of the operating lever 22 is pivotally supported on a support bracket 45 and is disposed opposite to a three-position switch 47 that switches the control state by the swinging movement of the operating arm 47a. An operating member 49 that operates integrally with 44 acts on the operating arm 47a of the switch 47,
In addition, the left and right free ends of the coiled spring 50 that urges the switch 47 to the neutral position are brought into contact with and locked to the operating member 49, respectively, and the operating lever 22 is operated against this urging force. According to the switch 47
At the same time, the operating member 49 is fitted and locked into the elongated hole 45a provided in the support bracket 45 to restrict the operating range of the operating lever 22 to within the operating range of the switch operating arm 47a. Machine control lever structure.
