    Abstract: An upper plate provided on upper ends of a filtration member and an inner tube includes a tubular portion along the inner tube, a rib formed so as to protrude inward in a radial direction from an inner circumference of the tubular portion, and a hole formed in the rib. A gripping member has a protrusion portion that protrudes downward from a body portion having a thick plate shape inserted into a hollow portion of the tubular portion. When the gripping member is mounted on the upper plate, the protrusion portion is inserted into the hole.

    Abstract: A filter case that internally includes a filter element including a filtration member having a substantially cylindrical shape that filters the liquid and an inner tube having a substantially cylindrical shape provided inside the filtration member. The inner tube includes a partition plate that covers a hollow portion of a side surface. A heater provided on a bottom surface of the filter case includes a substantially rod-shaped heating unit. The heating unit is inserted into a space surrounded by the side surface and the partition plate of the inner tube via a first hole formed at a position overlapping with the hollow portion of the inner tube in the first plate that covers a lower end of the filtration member.

    Abstract: A component that may not function properly when being removed from a case can be easily attached to the case and can be prevented from being removed from the case. When a substantially cylindrical inner tube is inserted into a case, a substantially cylindrical receiving part provided with claws is inserted along the inner tube, and the claws lock into the hole. When a filter element is inserted into the case, the inner tube is inserted along the inner peripheral surface of a filtration material, and an end member is inserted along a receiving part.

    Abstract: There is included a contamination degree acquiring section which acquires a degree of contamination of a liquid due to particles by correcting a sensor value from a measuring sensor, which measures particles in a liquid, based on at least one of a flow rate of the liquid, vibration applied to the measuring sensor, and ambient temperature of the measuring sensor. To provide a technique where it is possible to accurately measure an amount of particles included in a liquid used in a dynamic environment.

    Abstract: A fuel filter includes a housing including a filter case and a filter element. The filter element includes a first filter including a first filtration section formed in a tubular shape by folding a sheet-like filtration member into pleats, a second filter disposed on an inner side of the first filtration section, and a first plate at which the first filter and the second filter are disposed. The second filter includes a second filtration section formed in a tubular shape by connecting both ends of a mesh-patterned thin plate, a first end portion covering a first end of the second filtration section, and a second end portion covering a second end of the second filtration section, the second end being on a side opposite to the first end. The first plate is disposed in the head and has a first through-hole formed at a center thereof.
