ENGINE, AND SADDLE TYPE VEHICLE

摘要

An engine capable of providing a cam chain with tension with a reduced number of parts and a saddle riding type vehicle including the engine are provided. The engine (44) includes a chain chamber (210). The chain chamber stores a chain (154) and a tensioner (158) that provides the chain with tension. The tensioner includes a plate spring (166) and a blade shoe (168) that supports the plate spring and contacts the chain in the chain chamber. The engine further includes a support shaft (240) and a support part. The support shaft supports the tensioner in a swingable manner. The support part supports the tensioner by contacting a supported part (228) formed at the blade shoe. The support part supports the supported part so that the supported part can slide in the chain chamber when the tensioner swings around the support shaft.
