MEASUREMENT DEVICE, AND MEASUREMENT METHOD

摘要

Provided is a measurement device capable of detecting the wastage by means of a simple method. A measurement device for measuring the force applied to a bicycle (1) is provided with a side surface strain gauging set (371) capable of joining to the side surface of the crank (105) of the bicycle (1), and a side surface bridge circuit (373B) to which the output from the side surface strain gauging set (371) is inputted, wherein the side surface strain gauging set (371) and the side surface bridge circuit (373B) cancel at least a portion of the strain in the twisting direction and in the rotational direction being applied to the crank (105) and are capable of detecting the strain in the inner/outer direction.
