Abstract
A heating device of a PCV valve includes a PCV valve, a conduit and a bush. The PCV valve contacts the bush. The bush includes an outward protrusion. The outward protrusion includes a curved surface contacting an outside surface of the conduit in a manner of a surface-to-surface contact. Therefore, when the conduit is heated by engine cooling water, the bush contacting the conduit in the manner of a surface-to-surface contact is heated and the PCV valve contacting the bush is heated. Therefore, the PCV valve can be heated by the engine cooling water.
