第１フレーム１１は、枠体１２の外周面に環状取付フランジ１５を設ける。本実施例では、枠体１２の外周面の図において上下方向（第２フレーム２１との嵌め込み方向）の該枠体１２の下端面より上方に離隔した位置に取付フランジ１５を設け、枠体１２の下端面と取付フランジ１５の間を第２フレーム２１との衝合部１６とする。   The first frame 11 is provided with an annular mounting flange 15 on the outer peripheral surface of the frame body 12. In the present embodiment, the mounting flange 15 is provided at a position spaced apart from the lower end surface of the frame body 12 in the vertical direction (the fitting direction with the second frame 21) in the figure of the outer peripheral surface of the frame body 12. An abutting portion 16 with the second frame 21 is defined between the lower end surface of the first frame and the mounting flange 15.

第２フレーム２１は、枠体２２の外周面に環状取付フランジ２５を設ける。本実施例では、枠体２２の外周面の図において上下方向の該取付フランジ２５の直上に、第１フレーム１１の衝合部１６と衝合する衝合部２６を設ける。   The second frame 21 is provided with an annular mounting flange 25 on the outer peripheral surface of the frame body 22. In this embodiment, an abutting portion 26 that abuts against the abutting portion 16 of the first frame 11 is provided immediately above the mounting flange 25 in the vertical direction in the drawing of the outer peripheral surface of the frame body 22.

エアフィルタ装置１０は、第１フレーム１１と第２フレーム２１を嵌合し、それらの嵌め込み方向にてそれらの衝合部１６と衝合部２６を衝合した状態で、それらの取付フランジ１５と取付フランジ２５の間に間隔３２を形成する。   The air filter device 10 is fitted with the first frame 11 and the second frame 21, and in the state where the abutting portions 16 and the abutting portions 26 are abutted in the fitting direction, A gap 32 is formed between the mounting flanges 25.

エアフィルタ装置１０は、第１フレーム１１の枠体１２の内面に、第２フレーム２１の枠体２２の外面を嵌合した状態で、それらの嵌合面１２Ａ、２２Ａの間に間隙（不図示）を形成可能にするとともに、それらの嵌合面１２Ａ、２２Ａの少なくとも一方、本実施例では嵌合面２２Ａにおけるそれらの嵌め込み方向の奥側に該間隙をなくす凸部２７を設ける。本実施例では、第２フレーム２１の枠体２２の各外面（嵌合面２２Ａ）における取付フランジ２５、衝合部２６の直上の２ヶ所、従って全８ヶ所に、凸部２７を設けてある。   The air filter device 10 has a gap (not shown) between the fitting surfaces 12A and 22A in a state where the outer surface of the frame 22 of the second frame 21 is fitted to the inner surface of the frame 12 of the first frame 11. ) And at least one of the fitting surfaces 12A and 22A, in the present embodiment, a convex portion 27 that eliminates the gap is provided on the inner side of the fitting surface 22A in the fitting direction. In the present embodiment, convex portions 27 are provided at two locations immediately above the mounting flange 25 and the abutting portion 26 on each outer surface (fitting surface 22A) of the frame body 22 of the second frame 21, and thus at all eight locations. .

エアフィルタ装置１０は、第１フレーム１１と第２フレーム２１のフィルタ支持部１４、２４の横断面形状を、図１、図２に示す如く、空気がエアフィルタ装置１０を貫通する方向（図において上下方向）に沿って細長状（流線形状）をなすものとし、空気流に対する抵抗を低減する。   The air filter device 10 has a cross-sectional shape of the filter support portions 14 and 24 of the first frame 11 and the second frame 21 in the direction in which air passes through the air filter device 10 as shown in FIGS. It shall be elongated (streamline shape) along the vertical direction, and the resistance to air flow will be reduced.

フィルタ３０は、平板状をなし、例えば粗いアウタフィルタ、細かい中間フィルタ、粗いフィルタが接合された３層構造からなり、これらのフィルタを多孔質樹脂、本実施例ではポリウレタン樹脂にて構成し、各フィルタには集塵効果を高めるために、高粘度粘着剤を浸透させている。   The filter 30 has a flat plate shape, for example, a three-layer structure in which a coarse outer filter, a fine intermediate filter, and a coarse filter are joined. These filters are made of a porous resin, in this embodiment, a polyurethane resin. The filter is infiltrated with a high-viscosity adhesive to enhance the dust collection effect.

従って、エアフィルタ装置１０は、第１フレーム１１と第２フレーム２１を、フィルタ３０の装填状態で、上述の如くに嵌合し、図１に示す如く、外側の第１フレーム１１の枠体１２をエアクリーナボックス１のケース２の内周に挿着する。そして、第１フレーム１１の取付フランジ１５の上面をケース２の取付部２Ａに当て、第２フレーム２１の取付フランジ２５の下面にケース３の取付部３Ａを当て、それらの取付部２Ａ、３Ａをボルト止めすることにより、両フレーム１１、２１の取付フランジ１５、２５をそれらの取付部２Ａ、３Ａにて挟持し、エアクリーナボックス１の内部にエアフィルタ装置１０を気密に内蔵する。このとき、両フレーム１１、２１の取付フランジ１５、２５は、両取付部２Ａ、３Ａの挟み力により弾力的にたわみ変形し、両取付部２Ａ、３Ａにガタなく、気密性を保持する状態で挟み込まれる。   Therefore, the air filter device 10 fits the first frame 11 and the second frame 21 with the filter 30 loaded as described above, and the frame body 12 of the outer first frame 11 as shown in FIG. Is inserted into the inner periphery of the case 2 of the air cleaner box 1. Then, the upper surface of the mounting flange 15 of the first frame 11 is applied to the mounting portion 2A of the case 2, the mounting portion 3A of the case 3 is applied to the lower surface of the mounting flange 25 of the second frame 21, and the mounting portions 2A and 3A are attached. By fastening with bolts, the mounting flanges 15 and 25 of both the frames 11 and 21 are clamped by their mounting portions 2A and 3A, and the air filter device 10 is incorporated in the air cleaner box 1 in an airtight manner. At this time, the mounting flanges 15 and 25 of both the frames 11 and 21 are elastically bent and deformed by the clamping force of the both mounting portions 2A and 3A, and the both mounting portions 2A and 3A are not loose and maintain airtightness. It is caught.
