Abstract
A PCV valve coupling structure that couples a PCV valve to an internal combustion engine is employed in the PCV valve used to adjust a gas flow area of a blow-by gas passage. Blow-by gas in the internal combustion engine flows to an intake system of the internal combustion engine. In the PCV valve coupling structure, the PCV valve is coupled to the internal combustion engine in a non-removable manner.
