A blade tensioner of a blade tensioner system for a chain that drivingly connects a drive shaft to a driving shaft in an engine, that improves the chain-damping efficiency in a blade tensioner applied to the chain within an engine, prevents the sideways tilt of the blade tensioner during operation, in a blade tensioner applied to the chain in an engine, and provides a blade tensioner with a functionality that allows it to transversely guide a chain along the chain sliding face in a blade shoe, while maintaining the flexural deformability (i.e., the flexibility) of the blade shoe.

Blade tensioner and system for a chain

A tensioner device for an engine comprises a support member , a blade shoe coming into sliding contact with a timing chain having a base end section held by a cylinder block and a tip end section supported by the support member , and a leaf spring held by the blade shoe for pressing the blade shoe against the timing chain elastically. The support member is formed integrally with the cylinder block . The tip end section comes into sliding contact with a guide surface formed on the support member to be supported.
