To provide a booth, in which curtain installation work can be easily performed in a short time by dispensing with a fastener such as small screw or bolt and nut or a hook-and-loop fastener in installation of a curtain.

In the booth 1 including struts 2, a beam 3 connecting upper parts of the struts 2, and a curtain 4 closing an opening part between the struts 2, a dovetail groove 10 is formed over the whole length of the struts 2 and the beam 3, a curtain locking member 7 formed of an elastically deformable material is inserted to a loop part 4a formed by folding an end portion of the curtain 4, and the curtain locking member 7 is fitted to the dovetail groove 10 together with the loop part 4a at the end portion of the curtain 4.
