Description of the Related Art Conventionally, cylindrical filter elements have often been used as filter elements for an air cleaner used in an intake system of an automobile engine. In general, such a cylindrical filter element has a filter member in which a large number of mountain fold lines and valley fold lines are alternately and repeatedly formed, and an inner cylinder and an element body in which the filter member is developed with one edge in the width direction as an outer periphery. It has a structure in which upper and lower entrepreneurs are assembled.

FIG. 1 is a developed plan view of a filter material constituting a main body of the filter element according to the present invention, FIG. 2 is a side view of a filter element formed by molding the filter material of FIG. 1, and FIG. 3 is a plan view of FIG. is there. In the drawing, reference numeral 1 denotes a rectangular filter material, and a valley fold line 2, 2 and a mountain fold line 3, 3 parallel to the edge of the filter material 1 are formed in the filter material 1 in the longitudinal direction of the filter material 1. Are formed alternately at a substantially constant pitch w. In addition, the valley fold lines 4 and 4 are inclined from the intersection of the inner edge (the lower side in FIG. 2) and the mountain fold lines 3 and 3 to the outer edge (the upper side in the figure) in the final shape of the filter medium 1. Are formed between the valley fold lines 4 and 4 and the valley fold lines 2 and 2. Then, the valley fold line 2, the mountain fold line 5, the mountain fold line 3 at the inner edge of the filter medium 1
(Valley fold lines 4 and 4), mountain fold line 5, and valley fold line 2
The fold pitch w between the valley fold line 2 and the mountain fold line 3 is set to be substantially constant with a fold pitch w / 2 divided into two. Also,
The fold pitch of the valley fold line 2, the valley fold line 4, the valley fold line 4, and the fold line 3 at the outer edge of the filter medium 1 is the fold pitch w / the fold pitch w of the valley fold line 2 and the fold line 3 divided by three. 3 and is set substantially constant.

向に通過して使用することにより該空気を濾過する。After the filter medium 1 having the above-mentioned folded shape is bent along a mountain fold line or a valley fold line, both ends in the longitudinal direction are pulled in the longitudinal direction and both ends are bonded in an airtight manner with an adhesive. As a result, an umbrella-shaped filter element as shown in FIGS. 1 and 3 is formed. At this time, since the folding pitch of the inner edge is larger than the folding pitch of the outer edge, the opening 6 is formed at the center of the filter element. When the difference in the folding pitch between the inner edge portion and the outer edge portion is increased, the opening 6 becomes larger. Usually, however, the ratio of the folding pitch is preferably about 1.5 times. And since the folding pitch in the outer edge part of the filter medium 1 is substantially constant, the height dimension of the folding ridge in the outer part of the filter element is constant. Thereafter, both edges of the filter medium 1 are closed with a resin material or the like (not shown) and a flange is formed to be sandwiched and fixed between the housing and the cover. Thereby filtering the air.

エレントを長持ちさせることができる効果がある。According to the above-mentioned folded shape, many ridges are formed on the outer peripheral portion where the area of the umbrella-shaped filter element is large, so that the filtration area of the conventional filter element can be increased by 1.5 times. Since the folding width of the ridge is made smaller as going toward, there is an effect that the entire filtering area works effectively and the filter elongate can be prolonged.
