A measuring device capable of measuring a propulsion force and a force loss with a simple method is provided. This measuring device has: a first detection circuit (373a), that is, a bridged circuit to which a first strain gauge (369a) and a second strain gauge (369b), detection directions of which being set parallel to the length direction of a crank (105), are connected in order to detect bending deformation (x) of the crank; and a second detection circuit (373b), that is, a bridged circuit to which a third strain gauge (369c), detection direction of which being set parallel to the length direction of the crank (105), and a fourth strain gauge (369d), detection direction of which being set perpendicular to the length direction of the crank (105), are connected in order to detect bending deformation (y) and tensile deformation (z) of the crank (105). |
