CONSTITUTION: A PCV valve comprises a body having a valve and a spring inside, a thread portion to assemble a head cover, a pipe portion to connect a rubber hose. The PCV valve induces a blowby gas in a crankcase into an intake manifold. A freezing preventing structure of PCV valve comprises a thread portion(32) connecting with a head cover(11) of an engine. The thread portion is positioned between a body portion(31) and a pipe portion(33). The thread portion is connected inside of the head cover toward outside. A pipe portion to connect with a rubber hose(35) only is exposed to outside of the head cover.
