Amendment 2.10.4 The scope of claims for utility model registration is amended as follows.

[Scope of Claim for Utility Model Registration] In an unmanned operating device that operates an operating tool such as a brake pedal or clutch pedal operated by an operator by operating an unmanned operating mechanism in conjunction with actuator drive, the brake pedal is operated unmanned. The unmanned brake operation mechanism includes an operation load detection means for detecting an operation load of the unmanned brake operation mechanism, and an operation load detection means that stops the operation of the unmanned brake operation mechanism based on the operation load detection means detecting an operation load of a predetermined value or more. The unmanned clutch operation mechanism for unmanned operation of the clutch pedal includes a depression position detection means for detecting the operation of the clutch pedal to the lower limit position.
An unmanned operation device for a work vehicle, characterized in that the depressing position control means stops the operation of the clutch unmanned operating mechanism based on the detection by the depressing position detecting means.

Claims (1)
