Provided is a fixing member used in a support structure () for a bed. The support structure includes a lower frame (), an upper frame (), a raising/lowering mechanism () configured to raise and lower the upper frame with respect to the lower frame and including a support shaft () extending in a width direction of the bed, and a supported member () fixed to the upper frame and supported by the support shaft. The support shaft moves in a longitudinal direction of the bed while supporting the supported member when the upper frame is raised and lowered. The fixing member includes a plurality of fixing tools (Sto S) configured to fix the supported member to the upper frame. Each of the plurality of fixing tools includes a flexure element (SB) fixed to the upper frame at one end and fixed to the supported member at the other end, and a strain gauge (SG) attached to the flexure element.

A screwing machine includes a motor, an output shaft, a twist portion, a plate portion, a strain gauge, an amplification circuit. The output shaft is driven by the motor. To the output shaft, a bit is attachable. The twist portion is hollow. To the twist portion, torque applied to the output shaft is transmitted through a transmission element. The output shaft is configured to be indirectly twisted by the torque applied to the output shaft. The plate portion is integrally formed with the twist portion. The strain gauge is disposed on the twist portion. The amplification circuit is disposed on the plate portion. To the amplification circuit, a signal from the strain gauge is input.

A first pedaling force measurement device measures a plurality of pedaling force parameters acting on a first crank arm to one end of which a first pedal can be attached and to another end of which a crank shaft can be attached. The first pedaling force measurement device is provided with a strain-flexing part, a first parameter detection part and a first interference suppression part. Strain acting on the first crank arm is conveyed to the strain-flexing part. The parameter detection part is disposed on the strain-flexing part, and detects a plurality of parameters based on the strain being conveyed to the strain-flexing part. The interference suppression part suppresses interference in one parameter detected by the parameter detection part from the other parameters.
