Kind Code:
A1
Abstract:
Provided are: an engine that, using a low number of components, can put a cam chain under tension; and a saddle-type vehicle provided with said engine. Said engine (44) is provided with a chain chamber (210). Said chain chamber contains a chain (154) and a tensioner (158) that puts said chain under tension. Said tensioner includes a leaf spring (166) and a blade shoe (168) that supports said leaf spring and contacts the chain inside the chain chamber. The engine is also provided with a support shaft (240) and a support part. Said support shaft pivotably supports the tensioner. The support part supports the tensioner by contacting a supported part (228) formed on the blade shoe. When the tensioner pivots about the support shaft, the support part supports the supported part such that said supported part can slide within the chain chamber.
