連通ずる空気補給路と、この空気補給路の空気入口とな
る開口を設けたシート部と、このシート部に対向して上
記空気補給路内に設置され、コイルバネによって押し上

ート又は規制弁のいずれか一方に外周側から中心側に向
はテーパー状にした事を特徴とする負圧制御装置。an air supply path that bypasses the throttle valve and communicates the upstream side of the throttle valve with the intake manifold side; a seat portion provided with an opening that serves as an air inlet for the air supply path; and an air supply path that faces the seat portion. It has a plate-shaped regulation valve that is installed inside and pushed up by a coil spring, and when the engine intake negative pressure becomes larger than the set value, the regulation valve is separated from the seat part and air is introduced. The negative pressure control device operates to reduce the suction negative pressure, wherein either the seat or the regulating valve has a tapered shape from the outer circumferential side to the center side.
