Claims

[Scope of utility model registration request]

A command device that has a control lever and sends out a radio signal proportional to the operating angle of the control lever, and a control voltage that is mounted on the hydraulic vehicle type construction machine and receives the radio signal from the control device and responds to the received signal. and a receiver that drives a directional flow rate control valve for driving and controlling a hydraulic actuator using this control voltage, the receiver is 1, and within the operating range of the control lever of the command unit, the receiver is A circuit that controls the low flow rate range of the output flow rate of the directional flow control valve according to the signal, and outputs a control voltage that sets the output flow rate of the directional flow control valve to the maximum value upon detecting the end of operation of the operating lever. A wireless device characterized by comprising:
