Abstract
A diesel filter includes a filter member and a water reservoir formed below the filter member. The filter member has a case, a cap for closing the opening of the case, an element, and an element-holding member for holding an upper part of the element, and is detachably housed in the case. The element-holding member has an opening that allows fuel to flow out, and the fuel introduced from a fuel inlet port to a portion above the element-holding member is then introduced to the water reservoir via a passage formed between the inner peripheral surface of the case and the outer peripheral surface of the element.

A diesel filter comprising:
- a case including an opening that is upwardly opened;
- a cap detachably attached to the opening of the case for closing the opening;
- and
- a filter member detachably housed in the case, the filter member including an element and an element-holding member for holding an upper part of the element,
- wherein:
- in a state where the filter member is housed in the case, a water reservoir is formed in the case below the filter member, and a passage is formed between an inner peripheral surface of the case and an outer peripheral surface of the element so as to introduce fuel that has been introduced to a portion above the element-holding member into the water reservoir,
- the element-holding member has an opening for allowing the fuel to flow out from the element, the opening being in communication with a fuel outlet port formed in the cap,
- wherein the element-holding member holds the upper part of the element such that a space is maintained above the element between a top surface of the element and a bottom surface of the element-holding member, and
- the element-holding member includes a flange which is provided at an outer periphery of the element-holding member and which includes openings through which the fuel flows,
- the flange is held by the cap and the case in a state where the flange of the element-holding member is placed on a top surface of a middle stepped portion of the case, the cap is placed on a top surface of an upper stepped portion of the case, and the opening of the case is closed by the cap, and
- a sealing member is placed in direct contact with the middle stepped portion and is sandwiched between the middle stepped portion and the cap.
