- 摘要：
PROBLEM TO BE SOLVED: To provide a wall suction bag turning down the volume of a sound when an air bubble breaks and inhibiting water level rising caused by air, which allows a user to comprehend accurate suction pressure.
SOLUTION: A pressure control part 40 controls the suction pressure to certain pressure by introducing air from an air inlet port 15 through pressure control water W2 into a gas region 13, where the sound when the air bubble B breaks can be extinguished since a porous body 44 provided with the pressure control water W2 breaks up and vanishes the air bubble B generated from the air passing through the pressure control water W2. The air (bubble) passes along a channel 44a provided with the porous body 44, which can prevent the water rising by the air stored in the porous body 44 and allows the user to comprehend accurate suction pressure from the liquid level height of the pressure control water W2.
