MEASUREMENT DEVICE, AND MEASUREMENT METHOD

摘要

Provided is a measurement device capable of detecting the torque by means of a simple method. A measurement module (301) for measuring the force applied to a bicycle (1) is provided with an upper/lower surface strain gauging set (369) capable of joining to the upper surface side or lower surface side of the crank (105) of the bicycle (1), and an upper/lower surface bridge circuit (373A) to which the output from the upper/lower surface strain gauging set (369) is inputted, wherein the upper/lower surface strain gauging set (369) and the upper/lower surface bridge circuit (373A) cancel at least a portion of the strain in the twisting direction and in the inner/outer direction being applied to the crank (105) and are capable of detecting the strain in the rotational direction.
