Abstract
A valve timing transmission apparatus is disclosed that increases the freedom of attachment positions for a pivot pin supporting a one end of timing chain and enables arrangement of a chain tensioner in an optimum position for tensioning of the timing chain. An opening having a diameter greater than a sprocket is provided on the drive sprocket side of an outer side wall of a timing chamber which is formed in one side wall of an engine main body and which accommodates the timing chain. A lid plate is removably secured to the engine main body so as to close the opening. Support bosses supporting both ends of the pivot pin are formed in opposite walls of the engine main body and the lid plate.
