。 A pulley-belt transmission system connects the rotational force from the crankshaft to a driven part such as a camshaft, and a tension pulley biased by an elastic tension control mechanism to control the tension of the belt is mounted on the front of the cylinder block. The tension control mechanism is covered from the outside by a fixed belt cover, and the tension control mechanism has a main body that is inserted from the outside into an insertion hole of the cylinder block, and a tension control mechanism that is elastically movable in and out of the main body and cooperates with a tension pulley. A tension member that applies tension to the belt by applying tension to the belt, a removable pop-out prevention pin that maintains the elastic tension in a contracted position within the main body before installation, an insertion portion of the pop-out prevention pin, and a sliding portion of the tension member. a belt tensioning device for an internal combustion engine, comprising elastic means for sealing the insertion portion of the main body into the hole.
