　図７Ｂはクリーナ本体４４の平面図であって接続面４７の形状を示す図である。エレメントホルダ４３の下方開口部４３２とクリーナ本体４４の本体開口部４４２の接続部分には接続面４７が形成されている。接続面４７は図７Ｂの実線で表された形状を有しており、接続面４７において、クリーナ本体４４とエレメントホルダ４３とが接続している。本実施形態の場合、接続面４７は、下方開口部４３２と本体開口部４４２の形状に沿った無端の面である。また、図５Ｂで示すように、本実施形態の場合、接続面４７は、車両側面視で後方かつ上方に傾斜している。また、仮想面Ｖは、接続面４７を含む面であり、本実施形態の場合、接続面４７と同様に車両側面視で後方かつ上方に傾斜している。 Ｂ FIG. 7B is a plan view of the cleaner main body 44, showing the shape of the connection surface 47. A connection surface 47 is formed at a connection portion between the lower opening 432 of the element holder 43 and the main body opening 442 of the cleaner main body 44. The connection surface 47 has a shape represented by a solid line in FIG. 7B, and the cleaner body 44 and the element holder 43 are connected on the connection surface 47. In the case of the present embodiment, the connection surface 47 is an endless surface that follows the shapes of the lower opening 432 and the main body opening 442. As shown in FIG. 5B, in the case of the present embodiment, the connection surface 47 is inclined rearward and upward in a vehicle side view. Further, the virtual surface V is a surface including the connection surface 47, and in the case of the present embodiment, similarly to the connection surface 47, is inclined rearward and upward in a vehicle side view.
　図５Ａないし図５Ｃを再び参照する。クリーナケース４２、エレメントホルダ４３およびクリーナ本体４４は、上述のように開口部同士で接続するほか、締結部材により互いに締結されている。本実施形態の場合、締結部材はねじである。クリーナケース４２は、締結部材５１ａおよび５１ｂによりエレメントホルダ４３とともにクリーナ本体４４と締結され、締結部材５１ｃおよび５１ｄによりエレメントホルダ４３と締結される。また、エレメントホルダ４３はさらに、締結部材５２ａおよび５２ｂによりクリーナ本体４４と締結されている。例えば、エレメントホルダ４３は、締結部材５１ｃおよび５１ｄに螺合するねじ受け部を、クリーナ本体４４は締結部材５１ａおよび５１ｂならびに５２ａおよび５２ｂに螺合するねじ受け部をそれぞれ有している。 再 び Refer to FIGS. 5A to 5C again. The cleaner case 42, the element holder 43, and the cleaner main body 44 are connected to each other by the openings as described above, and are fastened to each other by the fastening members. In the case of the present embodiment, the fastening member is a screw. The cleaner case 42 is fastened to the cleaner main body 44 together with the element holder 43 by fastening members 51a and 51b, and fastened to the element holder 43 by fastening members 51c and 51d. The element holder 43 is further fastened to the cleaner main body 44 by fastening members 52a and 52b. For example, the element holder 43 has a screw receiving portion screwed to the fastening members 51c and 51d, and the cleaner main body 44 has a screw receiving portion screwed to the fastening members 51a and 51b and 52a and 52b, respectively.
　＜エレメントホルダの係止構造＞
　エアクリーナ４１のメンテナンスにおいて、エレメントホルダ４３からクリーナエレメントを取り外す場合には、クリーナケース４２が取り外されるため、エレメントホルダ４３とクリーナ本体４４とは、締結部材５２ａおよび５２ｂにより互いに締結された状態となる。このような状態でクリーナエレメント４５を取り外すと、例えば、エレメントホルダ４３の、締結部材により締結されていない車両後方側の部分がクリーナエレメント４５とともにクリーナ本体４４から外れてしまう場合がある。このようにエレメントホルダ４３がクリーナ本体４４から外れてしまうと、作業効率が低がり、エアクリーナ４１のメンテナンス性が低下する。そこで、本実施形態では、以下の係止構造を採用している。 <Element holder locking structure>
When the cleaner element is removed from the element holder 43 during maintenance of the air cleaner 41, the cleaner case 42 is removed, so that the element holder 43 and the cleaner body 44 are fastened to each other by the fastening members 52a and 52b. If the cleaner element 45 is removed in such a state, for example, a portion on the vehicle rear side of the element holder 43 that is not fastened by the fastening member may come off the cleaner body 44 together with the cleaner element 45. When the element holder 43 is detached from the cleaner main body 44 in this way, the working efficiency is reduced, and the maintainability of the air cleaner 41 is reduced. Therefore, in the present embodiment, the following locking structure is employed.
　図５Ａないし図６Ｃおよび図８を参照する。図８は、図３のＩＩＩ－ＩＩＩ線断面図である。クリーナ本体４４は、エレメントホルダ４３の位置を規制する係止部４４３を有している。係止部４４３は、クリーナエレメント４５の着脱方向へのエレメントホルダ４３の位置を規制することにより、クリーナエレメント４５を取り外す際にエレメントホルダ４３がともに外れることを防いでいる。本実施形態の場合、係止部４４３は、エレメントホルダ４３の車両上下方向の位置を主に規制しているが、クリーナエレメント４５の着脱方向に合わせて他の方向への移動を規制してもよい。 参照 Refer to FIG. 5A to FIG. 6C and FIG. FIG. 8 is a sectional view taken along line III-III of FIG. The cleaner main body 44 has a locking portion 443 that regulates the position of the element holder 43. The locking portion 443 prevents the element holder 43 from coming off when the cleaner element 45 is detached by restricting the position of the element holder 43 in the attaching / detaching direction of the cleaner element 45. In the case of the present embodiment, the locking portion 443 mainly regulates the position of the element holder 43 in the vehicle vertical direction. However, even if the locking portion 443 regulates the movement in the other direction in accordance with the mounting / removing direction of the cleaner element 45. Good.
　係止部４４３は、クリーナ本体４４から、接続面４７を含む仮想面Ｖよりもエレメントホルダ４３側かつ外方に延長される複数の延長部４４５，４４６と、延長部４４５，４４６の端部間（端部４４５ａ，４４６ａ間）を接続する橋渡し部４４７とを含む。 The locking portion 443 extends from the cleaner main body 44 to a plurality of extension portions 445 and 446 extending outward from the virtual surface V including the connection surface 47 toward the element holder 43 and ends of the extension portions 445 and 446. (Between the end portions 445a and 446a).
　また、エレメントホルダ４３は、係止部４４３に向けて突出し、係止部４４３に係止される突出部４３４を有している。突出部４３４は、クリーナ本体４４と、延長部４４５，４４６と、橋渡し部４４７とにより囲まれる開口４４８に挿入される。本実施形態の場合、突出部４３４は、開口４４８に挿入されると、開口４４８内で橋渡し部４４７に係止され、上下方向の移動が規制される。 The element holder 43 has a protruding portion 434 that protrudes toward the locking portion 443 and is locked by the locking portion 443. The protrusion 434 is inserted into an opening 448 surrounded by the cleaner body 44, the extensions 445, 446, and the bridge 447. In the case of the present embodiment, when the protruding portion 434 is inserted into the opening 448, it is locked by the bridging portion 447 inside the opening 448, and the movement in the vertical direction is restricted.
　上記構成により、クリーナ本体４４に対するエレメントホルダ４３の位置が規制されるので、クリーナエレメント４５を取り外す際にエレメントホルダ４３がクリーナ本体４４に装着された状態で保持される。したがって、エアクリーナのメンテナンス性をより向上することができる。また、係止部４４３および突出部４３４を設けることにより、ねじ等の締結部材が不要となる。また、係止部４４３および突出部４３４は一体成形が可能である。したがって、部品点数を削減することができる。さらに、ねじ等の締結部材が不要のため、締結部材により締結するためのスペースを確保する必要がなくなるため、係止部４４３上方のレイアウトの自由度をより向上することができる。 に よ り With the above configuration, the position of the element holder 43 with respect to the cleaner main body 44 is regulated, so that when the cleaner element 45 is removed, the element holder 43 is held in a state mounted on the cleaner main body 44. Therefore, the maintainability of the air cleaner can be further improved. Further, by providing the locking portion 443 and the protruding portion 434, a fastening member such as a screw becomes unnecessary. Further, the locking portion 443 and the protruding portion 434 can be integrally formed. Therefore, the number of parts can be reduced. Furthermore, since a fastening member such as a screw is not required, it is not necessary to secure a space for fastening with the fastening member, so that the degree of freedom of layout above the locking portion 443 can be further improved.
　特に、本実施形態の場合、インレットダクト４８の先端部４８ａは二重管の構造を有しているため、先端部４８ａの外径がインレットダクト４８の他の部分の外径より大きく構成されている。このため、先端部４８ａの下側の空間が小さくなり、例えば締結部材等を組み付けるための空間を確保できない場合がある。しかしながら、本実施形態の構成を採用することにより、締結部材等を組み付けるための空間が不要なるので、先端部４８ａに二重管（襟巻状）の構造を採用しながら、インレットダクト４８の下方の位置においてエレメントホルダ４３とクリーナ本体４４とを係合することができる。特に、本実施形態の場合、インレットダクト４８の先端部４８ａと係止部４４３は側面視で上下方向に重なるように配置されているため、先端部４８ａと係止部４４３とがより近接している。しかしながら、このような位置関係であってもエレメントホルダ４３とクリーナ本体とを係合することができる。なお、係止部４４３は、その全部が先端部４８ａと重なってもよく、また、その一部が先端部４８ａと重なってもよい。 In particular, in the case of the present embodiment, since the distal end portion 48a of the inlet duct 48 has a double pipe structure, the outer diameter of the distal end portion 48a is configured to be larger than the outer diameter of other portions of the inlet duct 48. I have. For this reason, the space below the distal end portion 48a is reduced, and for example, a space for assembling a fastening member or the like may not be secured. However, by adopting the configuration of the present embodiment, a space for assembling a fastening member or the like is not required. Therefore, while adopting a double pipe (collar-shaped) structure at the distal end portion 48a, the lower portion of the inlet duct 48 is formed. In the position, the element holder 43 and the cleaner main body 44 can be engaged. In particular, in the case of the present embodiment, since the distal end portion 48a of the inlet duct 48 and the locking portion 443 are arranged so as to overlap in the vertical direction in a side view, the distal end portion 48a and the locking portion 443 are closer to each other. I have. However, even in such a positional relationship, the element holder 43 and the cleaner main body can be engaged. The entirety of the locking portion 443 may overlap with the distal end portion 48a, or a part thereof may overlap with the distal end portion 48a.
　また、本実施形態の場合、橋渡し部４４７は、クリーナ本体４４側から、エレメントホルダ４３側かつ内方に向かって傾斜した傾斜部４４９を有している。これにより、突出部４３４をエレメントホルダ４３側から斜めに挿入することができるため、エレメントホルダ４３を取り付けやすくなる。したがって、エレメントホルダ４３の組付性をより向上することができる。なお、本実施形態の場合、橋渡し部４４７の下側の面は、傾斜部４４９と、突出部４３４の上側の面に沿った部分とを有しているが、橋渡し部４４７の下側の面全体が傾斜部４４９でもよい。 In addition, in the case of the present embodiment, the bridging portion 447 has an inclined portion 449 that is inclined inward from the cleaner body 44 toward the element holder 43. Accordingly, the protrusion 434 can be inserted obliquely from the element holder 43 side, so that the element holder 43 can be easily attached. Therefore, the assemblability of the element holder 43 can be further improved. In the present embodiment, the lower surface of the bridging portion 447 has an inclined portion 449 and a portion along the upper surface of the protruding portion 434, but the lower surface of the bridging portion 447. The whole may be the inclined portion 449.
　また、本実施形態の場合、エレメントホルダ４３は突出部４３４よりもクリーナ本体４４側に配置された位置決め部４３５を有し、クリーナ本体４４は、位置決め部４３５と係合する位置決め部４５０を有している。本実施形態の場合、位置決め部４３５が凸部４３５ａであり、位置決め部４５０が凸部４３５ａを受け入れる凹部４５０ａである。これらの構成により、クリーナ本体４４に対するエレメントホルダ４３の仮想面Ｖの面上の方向の位置を規制することができる。 In the case of the present embodiment, the element holder 43 has a positioning portion 435 disposed closer to the cleaner main body 44 than the projecting portion 434, and the cleaner main body 44 has a positioning portion 450 that engages with the positioning portion 435. ing. In the case of the present embodiment, the positioning portion 435 is a convex portion 435a, and the positioning portion 450 is a concave portion 450a that receives the convex portion 435a. With these configurations, the position of the element holder 43 in the direction on the virtual plane V with respect to the cleaner main body 44 can be regulated.
　本実施形態の場合、位置決め部４３５および４５０は、それぞれ接続面４７に沿って無端状に形成されており、接続面４７上で互いに係合している。また、位置決め部４３５および４５０は、一方が凸部、他方が凹部であればよく、位置決め部４３５が凹部であり、位置決め部４５０が凸部である構成も採用可能である。しかしながら、本実施形態の構成では、上下方向で下側の位置決め部４５０が凹部４５０ａを有していることにより、後述のようにシール部材４５０ｂを有する構成を採用する場合に凹部４５０ａにシール部材４５０ｂが保持されるのでエレメントホルダ４３を取り外し時にシール部材４５０ｂの落下を防ぐことができる。 In the case of the present embodiment, the positioning portions 435 and 450 are formed endlessly along the connection surface 47, and are engaged with each other on the connection surface 47. The positioning portions 435 and 450 only need to have one convex portion and the other concave portion, and a configuration in which the positioning portion 435 is a concave portion and the positioning portion 450 is a convex portion can be adopted. However, in the configuration of the present embodiment, since the positioning portion 450 on the lower side in the vertical direction has the concave portion 450a, when the configuration having the seal member 450b is employed as described later, the seal member 450b is provided in the concave portion 450a. Is held, it is possible to prevent the sealing member 450b from falling when the element holder 43 is removed.
　図６Ａないし図７Ｂを再び参照する。本実施形態の場合、接続面４７はシール面４７ａである。例えば、凸部４３５ａおよび凹部４５０ａが、これらの間に設けられたシール部材４５０ｂを挟むことによりシール面４７ａが形成される。突出部４３４はシール面４７ａに沿って複数設けられてもよく、本実施形態では２つ設けられている。これにより、突出部４３４を橋渡し部４４７が延設している長さと同じ長さにわたって設ける必要がなく、突出部の軽量化を図ることができる。また、１つの突出部４３４に対して１つの開口４４８を設ける場合と比べて、これらの部品の許容誤差が大きくなるので、成形品の製造をより容易に行うことができる。 再 び Refer to FIGS. 6A to 7B again. In the case of the present embodiment, the connection surface 47 is a sealing surface 47a. For example, the convex portion 435a and the concave portion 450a sandwich the seal member 450b provided therebetween to form the seal surface 47a. A plurality of protrusions 434 may be provided along the seal surface 47a, and two protrusions 434 are provided in the present embodiment. Accordingly, it is not necessary to provide the protruding portion 434 over the same length as the bridging portion 447 extends, and the weight of the protruding portion can be reduced. In addition, compared to the case where one opening 448 is provided for one protruding portion 434, the tolerance of these components is increased, so that it is possible to more easily manufacture a molded product.
　図２および図９を参照する。図９は車両１を背面からみた図であって車体フレームと吸気構造４の位置関係を示す図である。本実施形態の場合、シール面４７ａが車両側面視でシートレール１３よりも上方に配置されている。他の部分と比べて外方に突出するシール面４７ａがシートレール１３の上方のスペースに配置されるので、シートレール１３の間のスペースをクリーナ本体４４の浄化室４４１のスペースとしてより大きく確保することができる。よって、エアクリーナ４１の容量をより大きく確保することができる。特に、本実施形態の場合、シートレール１３が後方かつ上方に傾斜して延設し、その上部に配置されるエアクリーナ４１のシール面４７ａも後方かつ上方に傾斜している。これにより、シートレール１３とシール面４７ａとの干渉を避けることができるので、エアクリーナの内部容量を最大化することができる。 参照 Refer to FIG. 2 and FIG. FIG. 9 is a view of the vehicle 1 as viewed from the rear, and shows a positional relationship between the vehicle body frame and the intake structure 4. In the case of the present embodiment, the seal surface 47a is disposed above the seat rail 13 in a vehicle side view. Since the sealing surface 47a protruding outward as compared with the other parts is arranged in the space above the seat rail 13, a larger space between the seat rails 13 is secured as a space for the purification chamber 441 of the cleaner main body 44. be able to. Therefore, a larger capacity of the air cleaner 41 can be secured. In particular, in the case of the present embodiment, the seat rail 13 extends rearward and upward inclining, and the sealing surface 47a of the air cleaner 41 disposed above the seat rail 13 also inclines rearward and upward. Thus, interference between the seat rail 13 and the sealing surface 47a can be avoided, so that the internal capacity of the air cleaner can be maximized.
　また、図３で示すように、上面視で、シール面４７ａとシートレール１３は一部が重なるように配置されている。これにより、車幅方向でシール面４７ａがシートレール１３よりも外側に突出しないため、左右方向でもスペースを拡大せず、配置することができる
　また、本実施形態の場合、インレットダクト４８の入り口（先端部４８ａ）とクロスフレーム１６とリアサスペンション１７上部とが側面視で上下方向に重なるように配置される。これにより、車両レイアウトをコンパクト化することができ、特に車両の前後方向にコンパクトにこれらを配置することができる。さらに、本実施形態の場合、インレットダクト４８の入り口が下方に傾くように配置される。これにより、車両後方での上下高さを低減することができ、エアクリーナ４１を上下方向にコンパクトに配置することができる。 Further, as shown in FIG. 3, the sealing surface 47a and the seat rail 13 are arranged so as to partially overlap each other when viewed from above. As a result, the sealing surface 47a does not protrude outside the seat rail 13 in the vehicle width direction, so that the space can be arranged without expanding the space in the left-right direction. In the case of the present embodiment, the entrance of the inlet duct 48 ( The distal end portion 48a), the cross frame 16, and the upper portion of the rear suspension 17 are arranged so as to overlap in the vertical direction in a side view. As a result, the vehicle layout can be made compact, and particularly, these can be compactly arranged in the front-rear direction of the vehicle. Further, in the case of the present embodiment, the inlet of the inlet duct 48 is disposed so as to be inclined downward. Thus, the vertical height behind the vehicle can be reduced, and the air cleaner 41 can be compactly arranged in the vertical direction.
　図９で示すように、背面から見ると、インレットダクト４８の先端部４８ａがクロスフレーム１６の上方に位置し、橋渡し部４４７がインレットダクト４８とクロスフレーム１６との間に車幅方向に延びて配置されている。これにより、インレットダクト４８とクロスフレーム１６との間のスペースに橋渡し部４４７が配置されるので、上下方向にコンパクトに配置することができる。また、クリーナ本体４４のクロスフレーム１６側の側壁４５１をよりクロスフレーム１６側に配置できるので、エアクリーナ４１の容量をより大きく確保することができる。 As shown in FIG. 9, when viewed from the back, the distal end 48 a of the inlet duct 48 is located above the cross frame 16, and the bridging portion 447 extends between the inlet duct 48 and the cross frame 16 in the vehicle width direction. Are located. Accordingly, the bridging portion 447 is arranged in the space between the inlet duct 48 and the cross frame 16, so that the bridge portion 447 can be compactly arranged in the vertical direction. Further, since the side wall 451 of the cleaner main body 44 on the cross frame 16 side can be further disposed on the cross frame 16 side, the capacity of the air cleaner 41 can be further secured.
　本発明は上記実施の形態に制限されるものではなく、本発明の精神及び範囲から離脱することなく、様々な変更及び変形が可能である。従って、本発明の範囲を公にするために、以下の請求項を添付する。 The present invention is not limited to the above embodiment, and various changes and modifications can be made without departing from the spirit and scope of the present invention. Therefore, to make the scope of the present invention public, the following claims are appended.
