a frame for maintaining a shape thereof;
a mesh member coupled to the frame and configured to remove foreign substances contained in fuel, wherein the mesh member includes: a first mesh member, and a second mesh member, where the second mesh member has a mesh size smaller than a mesh size of the first mesh member; and
an opening unit for opening and closing a fuel path in the first mesh member,
wherein the opening unit includes:
a temperature-sensitive switch, which is turned on/off depending on a temperature of the fuel; and
a dielectric elastomer actuator mounted on a lower end of the frame and configured to open the fuel path in the first mesh member upon application of power from a battery through the temperature-sensitive switch and to close the fuel path in the first mesh member upon interruption of application of the power from the battery.
