An apparatus for measuring a tension (T) of a belt in a spanned state includes a vibration detector (1A) for detecting a vibration of the belt, a vibration frequency arithmetic unit (2A) for arithmetically determining a vibration frequency on the basis of the vibration as detected, and a tester (3) equipped with a display device (35). The tester (3) includes an information processor (32) for arithmetically determining a tension (T) of the belt on the basis of the vibration frequency supplied from the vibration frequency arithmetic unit (2A) and information about the belt read out from a storage medium (9), and the display device (35) for displaying the result of the arithmetic operation performed by the information processing means. The storage medium (9) is constituted by an external memory unit capable of being detachably connected to the tester (3). The tension measuring apparatus can profitably be used for detection of a tension (T) of a belt of a belt transmission mechanism employed in a motor vehicle with high accuracy and flexibility.
