Engagement holes 11 as engagement portions or engaged portions with which the engagement protrusions 10 are engaged are formed at the right flange portion 5e of the frame 5b, and the shutter 5 slides to the above-described regular mounting position. When this is done, the engaging projection 10 and the engaging hole 11 are engaged, and the sliding of the shutter 5 in the left-right direction is locked.

図２及び図４に示すように、シャッター５を本体フレーム２に装着するときは、右手でシャッター５の右側のツマミ部９を抓み、シャッター５のフランジ部５ｅ左側を本体フレーム２のフランジ部３の右側に当接させ、シャッター５を左方へスライドさせ、図５に示すように、シャッター５の上部の張出し部７ａ、７ａ、下部の張出し部７ｂをそれぞれ本体フレーム２の上部の引掛け部６ａ、６ａ、下部の引掛け部６ｂに係合させ、かつ、シャッター５の左端をストッパ１２に当接させ、本体フレーム２の面板３の右側の係合凸部１０と、シャッター５の右側のフランジ部５ｅの係合孔１１とを係合させる。   As shown in FIGS. 2 and 4, when the shutter 5 is mounted on the main body frame 2, the right-hand knob portion 9 of the shutter 5 is pinched with the right hand, and the left side of the flange portion 5 e of the shutter 5 is the flange portion of the main body frame 2. 3, the shutter 5 is slid to the left, and as shown in FIG. 5, the upper projecting portions 7 a and 7 a and the lower projecting portion 7 b of the shutter 5 are respectively hooked on the upper portion of the main body frame 2. Engage with the parts 6a, 6a and the lower hooking part 6b, and with the left end of the shutter 5 abutting against the stopper 12, the engagement convex part 10 on the right side of the face plate 3 of the main body frame 2 and the right side of the shutter 5 The engaging portion 11 of the flange portion 5e is engaged.

シャッター５は、本体フレーム２の面板３、上部の引掛け部６ａ、６ａ、下部の引掛け部６ｂ、ストッパ１２及び係合凸部１０により、本体フレーム２に対して、上下、左右及び前後へ動かないように係止されるので、換気扇１００が、天井へ設置されてもシャッター５が重力により落下することはなく、また、シャッター５のツマミ部９を抓んで片手操作により本体フレーム２に装着することができる。   The shutter 5 is moved up and down, left and right, and front and rear with respect to the main body frame 2 by the face plate 3 of the main body frame 2, the upper hooking portions 6a and 6a, the lower hooking portion 6b, the stopper 12, and the engaging convex portion 10. Since it is locked so that it does not move, the shutter 5 does not fall due to gravity even if the ventilation fan 100 is installed on the ceiling, and it is attached to the main body frame 2 by holding the knob portion 9 of the shutter 5 and operating with one hand. can do.

また、上部の張出し部７ａが横方向に所定幅に形成され、上部及び下部の引掛け部６ａ、６ｂが横方向に所定幅に形成され、シャッター５の正規位置では、上部の張出し部７ａと上部の引掛け部６ａが重なり合い、かつ、下部の張出し部７ｂの左端が下部の引掛け部６ｂの左端に一致しているので、シャッター５を前記の正規位置から右方へ所定幅スライドさせれば、張出し部７ａ、７ｂと引掛け部６ａ、６ｂとの係合を解いてシャッター５を前方へ取り外すことができる。   Further, the upper overhanging portion 7a is formed with a predetermined width in the lateral direction, and the upper and lower hooking portions 6a, 6b are formed with a predetermined width in the horizontal direction. Since the upper hooking portion 6a overlaps and the left end of the lower overhanging portion 7b coincides with the left end of the lower hooking portion 6b, the shutter 5 can be slid rightward from the normal position by a predetermined width. In this case, the shutter 5 can be removed forward by releasing the engagement between the overhanging portions 7a and 7b and the hooking portions 6a and 6b.

また、図４及び図６に示すように、シャッター５を前記の正規位置までスライドさせないと、干渉部としてのツマミ部９が面板３から右側にはみ出すようになっていて、グリル８を本体フレーム２に装着するとき、グリル８の側面（枠部）８ｂとツマミ部９が干渉して、グリル８を本体フレーム２に装着することができないようになっている。これにより、シャッター５の誤装着を防止することができる。   As shown in FIGS. 4 and 6, if the shutter 5 is not slid to the normal position, the knob portion 9 as an interference portion protrudes from the face plate 3 to the right side, and the grill 8 is attached to the main body frame 2. When attaching to the main body frame 2, the side surface (frame portion) 8 b of the grill 8 and the knob portion 9 interfere with each other so that the grill 8 cannot be attached to the main body frame 2. Thereby, erroneous mounting of the shutter 5 can be prevented.
