Abstract
A belt tension adjustment apparatus for vehicles, including a rotational shaft of a rotor; a first coupling pin and a second coupling pin protruding in a direction perpendicular to the rotational shaft; an outer pulley penetrating the rotational shaft and having a first coupling part extending toward a front direction, the first coupling part enclosing the rotational shaft and having a first slit penetrating at a point corresponding to the first coupling pin, and the first slit having an arc shape convex in the front direction. An inner pulley is disposed between the rotor and the outer pulley, to penetrate the rotational shaft, and has a second coupling part extending in a rear direction. The second coupling part encloses the rotational shaft and has a second slit penetrating at a point corresponding to the second coupling pin. The second slit has an arc shape convex in the rear direction.
