制御装置。[Claims for Utility Model Registration] A pressure control device comprising a pressure reducing valve that connects an output port to an input port in response to an electronically controlled control pressure to make the output pressure from the output port a value corresponding to the control pressure, A switch is provided that operates at a pressure reducing valve stroke position that communicates between the output port and the input port at a maximum opening degree, and when raising the output pressure, an electronic control amount is determined so that the control pressure reaches a maximum value,
A pressure control device further comprising electronic control amount determining means for determining the electronic control amount so that the control pressure becomes a target value in response to the operation of the switch.
