とするクランクケースベンチレーシヨンバルブ。 By receiving negative pressure in the intake passage, the valve body that closes the valve hole is pushed up against the force of the spring, causing the atmospheric temperature to be low in the crankcase ventilation valve that recirculates the blow-by gas. A crankcase ventilation valve characterized in that a spring made of a shape memory alloy whose free length increases when the valve body is moved is disposed on the opposite side of the spring with respect to the valve body, and supports the valve body.
