Abstract: A spool, including a substantially cylindrical flange portion and a substantially cylindrical front end portion which is thinner than the flange portion and whose center axis is substantially coincident with the center axis of the flange portion, is provided in a manner capable of slidingly moving in a cavity formed in a casing. The flange portion is inserted in a first cavity which has a center axis substantially coincident with the center axis of the casing and which has an inner diameter that is substantially the same as the diameter of the flange portion in length. The front end portion is inserted in a second cavity which is formed with its center axis being substantially coincident with the center axis of the casing, and which has an inner diameter greater than the diameter of the front end portion and less than the inner diameter of the first cavity in length. The rotation limiting portion, which has a rod-like shape thinner than the front end portion and which is provided along the front end portion in a manner contacting the side surface of the front end portion, is inserted in a groove portion formed on the side face of the second cavity. When the flange portion slidingly moves along the first cavity, the rotation limiting portion slidingly moves along the groove portion.

Abstract: An adhesive applied to an inner side of a bottom surface of a plate having a substantially hollow cylindrical shape with a closed bottom fixes one end of the filter material and the plate to each other. A plurality of projections located at different positions in a circumferential direction are formed on the plate, and a leading end of each of the projections comes into contact with the filter material.
