Abstract: An information output device that can output the position of a load applied to the pedal is provided. A strain gauge is provided on the inner face of a crank of a bicycle and detects strain occurring in the crank. A cycle computer display unit displays an image showing the center position of the load applied to the pedal connected to the crank based on the tangential force and the torsional torque calculated based on the output values of the first strain gauge to the sixth strain gauge.

Abstract: There is provided a measuring device capable of measuring a propulsion force and a loss force by using a simple method. A first detection circuit that is a bridge circuit, to which a first strain gauge and a second strain gauge disposed such that detection directions are parallel to a longitudinal direction of a crank are connected, detecting bending deformation x occurring in the crank, and a second detection circuit that is a bridge circuit, to which a third strain gauge disposed such that a detection direction is parallel to the longitudinal direction of the crank and a fourth strain gauge disposed such that a detection direction is perpendicular to the longitudinal direction of the crank are connected, detecting bending deformation y and tensile deformation z occurring in the crank are included.
