LIQUID TANK, BREATHER DEVICE FOR THE LIQUID TANK, AND EXHAUST GAS PURIFICATION DEVICE FOR ENGINE

摘要

In a liquid tank 7 provided with a pressure relief vent hole 25, a shielding plate 30 surrounding the vent hole 25 is disposed inside the liquid tank 7. The shielding plate 30 forms an isolated chamber 32 communicated with the vent hole 25. In a portion 31 a located to the side of the vent hole 25 in the horizontal direction, the shielding plate 30 allows communication between the isolated chamber 32 and an inner space in the liquid tank 7 excluding the isolated chamber 32. On the other hand, in a portion 31b located below the vent hole 25, the shielding plate 30 blocks movement of the liquid between the isolated chamber 32 and the inner space.
