The outer case 2 includes a discharge path 4 for discharging released gas from a discharge valve to the outside. The discharge path 4 includes: a first collision plate 11 for reversing the flow direction of a released gas; a second collision plate 12 facing the first collision plate 11; an inflow duct 16; a discharge duct 18; a first guide plate 13 placed in the discharge duct 18; a reflective duct 17 for guiding the released gas to the second collision plate 12; a second guide plate 14 that separates the inflow duct 16 and the reflective duct 17; and a subplate 15 placed between the second guide plate 14 and the first guide plate 13. Between the lower edge of the second guide plate 14 and the outer case 2, a passage gap 24 for the released gas is formed, and between the upper edge of the subplate 15 and the outer case 2, an upper edge gap 22 is formed.SELECTED DRAWING: Figure 6
