`face 418 functions as the exhaust passage 46, and the exhaust air from the workroom 15
`flows into the blower 14 side for exhaust air through the exhaust passage 45. The exhaust
`oassage 45 has the upper duct 4.65 (exhaust duct) which extends between the back face. 41%
`of the housing 17, and the back plates 43 u
`succeeding t. e lower duct 45A which passes
`along the lower part of the work plate 42, and the lower duct 46A. The lower part end oi" the

`After it passes the catalyst. 2.8 for inhalation of air, the air (gas) of the. outside of the glove box
`11 flows into the inhalation-of-air chamber 33 via the valve 29 for inhalation of air. and it
`spreads crosswise [ of the inhalatiomof—air chamber 33 ,I' whole 3, it passes the air cleaner 34,
`and dust is removed, and it flows from the uooer part in the workroom 16. The air which
`flowed in the workroom 16 continues crosswise [ whole
`in the workroom 16, flows caudad
`i‘r m the. upper part, reaches the lower duct 46A from each exhaust hole part 451 of the front

`passes the exhaust air filter 37, and flows into the exhaust chamber 36, The Sr which flowed
`into the exhaust. chamber 36 is sucked out. by the blower 14 for exhaust air, and is exhausted
`outside through the exhaust valve 30 and the catalyst 31 for exhaust air.

`Fig.3 and Fig.4 are the figures which looked at the inside or" the workroom 16 from the upper

`As shown in Fig.3, the concave part 47 for door accommodation of the recessed approximately
`rectangle is caudad formed in the work plate 42 on the operation area ZS side. The concave
`
`part 47 for door accommodation is formed in accordance with the form of the,
`'nt box door
`23A, and as shown in Fig.4, when the joint box door 23A is in an opened state, it stores the
`joint box door 23A in the concave part. Where the joint box door 23A is stored in the concave
`part 47 for door accommodation, the upper surface of the joint box door 23A corresponds to
`the upper surface of the work plate 42, and becomes some work plates 42.

`That is, when performing culture, the joint box doc-r 23A is used by an opened state, and
`functions as a stand for work. Culture is performed mainly on th joint box door 23A, Thus,
`since the joint box door 23A is pushed down caudad to make an opened state and it
`accommodates in the concave part 47 for door accommodation, while being able to prevent
`the joint box, door 23A from barring the display of the display 26, the joint box door 23A can be
`used as a stand for work.
`The wall is provided between the concave part 47 for door accommodation, and the lower duct
`46A, and the concave part 47 {or door accommodation does not communicate the lower duct
`46A directly.

`The centrifuge 2i) is covered with the freely ooenable/ciosa‘oie covering device 26A, and is
