Abstract: The present invention provides a blade-type tensioner system for a chain that can easily improve spring properties. A blade-type tensioner includes a blade shoe and a blade spring positioned on the back side of chain sliding surface of the blade shoe so as to impart tension to a chain through the blade shoe. The blade shoe is pivotably supported around a shoulder bolt inserted into a proximal end portion of the blade shoe, and a distal end portion of the blade shoe is slidably supported on a supporting face provided in the engine. The distal end portion of the blade shoe contacts a flat, first supporting face at a point. When tension in the chain is increased, the distal end portion contacts a concave, second supporting face at a point which is continuous with the first supporting face.

Abstract: The present invention provides a process for producing surface-modified rubber that is useful as a recycled material having characteristics inherent in vulcanized rubber, wherein the surface-modified rubber is obtained in such a manner that waste vulcanized rubber resulting from scrap tires and so on is dipped in a silane-coupling agent diluted with a solvent to improve the adhesiveness of the rubber surface. Such a silane-coupling agent preferably has a mercapto group or an S—S bond and is used in such a manner that the agent is diluted so as to have a content of 0.5 to 5%. Furthermore, the present invention provides a process for producing surface-modified rubber, obtained by modifying the surface of vulcanized rubber by corona discharge treatment or the like, having a contact angle of 80 degrees or less. In this process, it is preferable that the vulcanized rubber is further treated with a silane-coupling agent.
