Abstract

In a wrapping type transmission structure for internal combustion engines, provided with a first wrapping type transmission system which includes a first tensioner urged into press contact with a first endless power-transmitting belt and which is disposed on a side wall of an engine body, and a second wrapping type transmission system which includes a second tensioner urged into press contact with a second endless power-transmitting belt and which is disposed at a location remoter from the engine body than the first wrapping type transmission system, a support shaft is fixed to the engine body and is inserted through the first and second tensioners which are relatively movable in a plane perpendicular to the axis of the support shaft, while permitting the movements of the tensioners in directions of press contact with the first and second transmitting belts. This enables the tensioner arrangement to be compact and permits an increase in freedom for disposition of the transmission systems.
