PURPOSE: A PCV valve is provided to prevent noise and abrasion, and to reduce manufacturing costs by decreasing the number of parts. CONSTITUTION: A PCV valve comprises a cover(20), a body(30), a valve body(50), and an elastic unit(60). An inlet(22) is formed in the cover. The body is connected to the cover with forming a flow path, and comprises an outlet(32). The valve body comprises a valve head(52). The valve body is formed inside the flow path in order that the valve head selectively secludes the inlet. An elastic member contacts with the valve head, and is formed inside the flow path to elastically support the valve body. A valve head gas groove(54) is formed on a surface contacting with the elastic member of the valve head.
