A vehicle for performances comprises a roof, a floor, and a roof lifting member that is disposed in an orthogonal direction between the floor and the roof. Also, roof extension panels are pivotably coupled to both sides of the upper end of the roof, and floor extension panels are pivotably disposed at both sides of the floor. In this case, the roof extension panels are spread, and then the roof is lifted up. Thereafter, the floor extension panels are spread, and then folding-type auxiliary panels are spread to both sides and fixed by supports. Next, flying speaker supporting trusses are pivoted to the outside by a certain angle to install flying speakers. Next, the visual equipment supporting trusses are spread to both sides, and then visual equipment is spread. Thereafter, an installation into a performance state is completed by shortening the length of a fixing cable.
