操作装置。[Scope of Claim for Utility Model Registration] A working machine having a boom, such as a crane, is mounted on a vehicle, and the working machine is powered by the power of the engine for driving the vehicle, which is taken out through a PTO that is operated by a PTO operating actuator. A work vehicle configured to be driven, in particular, a rotation speed limiting means comprising an actuator whose drive is controlled by a control means, the actuator controlling the maximum rotation speed of the engine to a predetermined maximum speed lower than that when the vehicle is running. The engine is equipped with a rotation speed limiting means arranged in relation to the accelerator control system of the engine so as to be able to change its position between a restriction position where the rotation speed is restricted and a release position where the restriction is released, wherein the rotation speed restriction means is in the restriction position. A limit state detecting means for directly or indirectly detecting this is provided, and the PTO operation actuator can be driven to the contact position only when the limit state detecting means detects the limit position of the rotation speed limiting means.
PTO in a work vehicle, characterized in that a relay switch controlled by the detection result of the limit state detection means is interposed in the operation circuit of the operation actuator.
Operating device.
