Claims

[Scope of utility model registration request]

A fan belt is wound between the cooling fan drive pulley that is integrally fixed to the flywheel, the fan pulley that is fixed to the cooling fan, and the tension pulley provided between both pulleys, and the flywheel and tension pulley are In a cooling fan drive mechanism for an internal combustion engine housed in a wheel cover, a tension lever is disposed near the cooling fan drive pulley, the tension lever having a threaded hole along the longitudinal direction at a rear end, The front end is provided with a support shaft perpendicular to the longitudinal direction, and an elongated hole is provided in the intermediate longitudinal direction, and the tension pulley is rotatably supported by the support shaft. The tip of the adjustment bolt screwed in toward the side is rotatably engaged in a fulcrum hole provided with a fixed part of the cylinder body, cylinder head, etc., and is brought into contact with the bottom of the fulcrum hole, and the tension is further increased. A fixing bolt is inserted into the long hole of the lever so as to be relatively movable along the length direction of the lever, and the tip of the fixing bolt is screwed onto the wall surface of the fixing part outside the flywheel cover. A belt tension device for an internal combustion engine, characterized in that the tension lever is sandwiched between a head and the fixing part, and the tension lever is fixed to the fixing part.
