A tension gauge for accurately and visually indicating the tension on an elongated element, such as an automobile fan belt, includes a frame, a spring-loaded actuating member supported for reciprocal movement on the frame, and an extender which is secured to and extends away from the frame and has a pair of spaced surfaces thereon at a location remote from the frame which engages one side of the element. A third surface located intermediate the pair of surfaces engages the same side of the element, is connected to the actuating member by a linkage mechanism and is reciprocally movable in a direction transverse of the element in response to reciprocal movement of the actuating member. A spring-loaded fourth surface engages the opposite side of the element and urges the element firmly against the third surface. An indicator on the frame provides a visual display of the position of the third surface relative to the pair of surfaces, such position being proportional to the tension on the element.
