PROBLEM TO BE SOLVED: To provide a cabinet which has a clean circumstance retaining mechanism and causes little variation of the wind velocity in the working space. SOLUTION: The safety cabinet 1 has a filter 26 and two rectification members 51 and 52 in the downstream of the filter 26, and the rectification members 51 and 52 are made of a punching metal and arranged so that the openings 55 and 56 are not superimposed mutually. The rectification members 51 and 52 are formed by bending a sheet of a punching metal and have a bent part 60, and an opening 61 is formed in the bent part 60. Air passing through the filter 26 is rectified by the rectification member 51, stays temporarily in a space 50 and is rectified again by the rectification member 52 so as to supply air with a uniform wind velocity into the working space 7.
