Note that no ribs are formed on the upper and lower sides of the lattice 101 in FIG. FIG. 5 is a bottom perspective view of the suction grill 10.

図６はエアフィルタ９を示す図であり、(a)は平面図、(b)は底面図である。このエアフィルタ９は、波形フィルタシート９１が装着される開口部９２と、その開口部９２の全周を囲む枠部９３とを備え、枠部９３の開口部９２を区画する４辺にリブ９４が形成されている。そして、波形フィルタシート９１の稜線と平行な、互いに対向する２辺のリブに係止穴９５が形成されている。枠部９３の内の波形の稜線と平行な辺のリブに係止穴９５を形成した理由は、波形の稜線と直交する辺のリブにはフィルタシート９１の波形を受けるガイド部を形成する必要があるからである。図７にこのエアフィルタ９の上面斜視図を示す。   6A and 6B are views showing the air filter 9, wherein FIG. 6A is a plan view and FIG. 6B is a bottom view. The air filter 9 includes an opening 92 to which the corrugated filter sheet 91 is attached and a frame portion 93 that surrounds the entire periphery of the opening 92, and ribs 94 are formed on four sides that define the opening 92 of the frame portion 93. Is formed. And the locking hole 95 is formed in the rib of 2 sides opposite to each other parallel to the ridgeline of the waveform filter sheet 91. The reason why the locking holes 95 are formed in the ribs on the sides parallel to the corrugated ridge lines in the frame 93 is that the ribs on the sides orthogonal to the corrugated ridge lines need to form guide portions for receiving the corrugated filter sheet 91. Because there is. FIG. 7 is a top perspective view of the air filter 9.

さて、図４および図５に示すように構成される吸込グリル１０に対して、図６および図７に示すように構成されるエアフィルタ９を装着すると、図３に示すように組み立てられる。すなわち、吸込グリル１０の各リブ１０６の各係止爪１０９に対して、エアフィルタ９の２辺のリブ９４の各係止穴９５を合わせると、図３の拡大断面に示すように両者が係合し、エアフィルタ９の枠部９３のリブ９４が吸込グリル１０の吸込口１０２のリブ１０６の外側に位置するように組み立てられる。このとき、エアフィルタ９の枠部９３のリブ９４の下面は吸込グリル１０のストッパ１０７に当接し、且つガイド柱１０８によって図４(a)において上下方向への移動が規制される。   Now, when the air filter 9 configured as shown in FIGS. 6 and 7 is attached to the suction grill 10 configured as shown in FIGS. 4 and 5, the assembly is performed as shown in FIG. That is, when the locking holes 95 of the ribs 94 on the two sides of the air filter 9 are aligned with the locking claws 109 of the ribs 106 of the suction grill 10, both are engaged as shown in the enlarged cross section of FIG. The ribs 94 of the frame portion 93 of the air filter 9 are assembled so as to be located outside the ribs 106 of the suction port 102 of the suction grill 10. At this time, the lower surface of the rib 94 of the frame portion 93 of the air filter 9 is in contact with the stopper 107 of the suction grille 10, and the movement in the vertical direction in FIG.

以上のようにして、吸込グリル１０およびエアフィルタ９が組み立てられた組立体を化粧パネル７の内側に装着したとき、図３の拡大断面に示したように、エアフィルタ９の枠部９３のリブ９４が吸込グリル１０の吸込口１０２のリブ１０６の外側に位置するので、ベルマウス６の下面開口部を風量増大のために拡大し、これに合わせて吸込グリル１０の開口部１０２を大きくしても、エアフィルタ９の枠部９３がエア吸込みの抵抗とはならない。また、吸込グリル１０の枠部１０３の内縁には、エアガイドＲ部１１０を形成しているので、エア吸込がなめらかになり、この部分でも抵抗が減少する。   When the assembly in which the suction grille 10 and the air filter 9 are assembled as described above is attached to the inside of the decorative panel 7, as shown in the enlarged cross section of FIG. Since 94 is located outside the rib 106 of the suction port 102 of the suction grill 10, the lower surface opening of the bell mouth 6 is enlarged to increase the air volume, and the opening 102 of the suction grill 10 is enlarged accordingly. However, the frame portion 93 of the air filter 9 does not serve as an air suction resistance. Moreover, since the air guide R part 110 is formed in the inner edge of the frame part 103 of the suction grill 10, air suction becomes smooth and resistance also decreases in this part.
