Claim:
1. An evaporated-fuel processing apparatus comprising: a sealing valve which is arranged in a communication path between atmosphere and a fuel tank mounted on a vehicle having an internal combustion engine, and shuts an internal space of the fuel tank off from the atmosphere; an open/close member which covers a fuel filling port of the fuel tank; a tank-internal-pressure detection unit which detects an internal pressure of the fuel tank; an open/closed-state detection unit which detects an open/closed state of the open/close member; a refueling-intention-information acquisition unit which acquires information indicating an intention of refueling; a running-state-information acquisition unit which acquires information on a running state of the vehicle; a control unit which issues an opening command for opening the sealing valve when the refueling-intention-information acquisition unit acquires the information indicating an intention of refueling, and allows the open/close member to open when a time elapsed from a moment at which the opening command is issued exceeds a first predetermined time; and an informing unit which provides an operator with information about refueling, wherein: the control unit issues the opening command when the refueling-intention-information acquisition unit acquires the information indicating the intention of refueling, allows the open/close member to open when the internal pressure of the fuel tank converges in a predetermined pressure range, and maintains the sealing valve in an open state when the open/closed-state detection unit detects that the open/closed state of the open/close member transitions from an open state to a closed state, and causes the informing unit to provide the operator with alarm information indicating that the open/close member is in the open state, in a period from a moment at which the control unit issues the command to close the sealing valve until a moment at which the open/closed-state detection unit detects a transition of the open/close state of the open/close member from the open state to the closed state, and wherein the control unit issues a command to close the sealing valve when the running-state-information acquisition unit acquires information indicating that the vehicle starts running.
