[Claims for Utility Model Registration] Consisting of a negative pressure detection passage provided in the inner part of the main body forming an intake air passage, and a metering orifice connecting the negative pressure detection passage and the inner peripheral wall of the intake air passage. In the negative pressure detection device, a space having a larger volume than the metering stop is formed on the inner circumferential wall of the intake air passage "1," and the metering stop is connected between this space and the negative pressure detection passage. A rapid pressure detection device, characterized in that the metering orifice' is arranged so as to be bent with respect to the direction in which the space extends.
