Abstract
The present invention provides a traction coefficient measurement device having a driving roller rotated around a driving shaft, a driven shaft is rotated together with a driven shaft, corresponding to the rotation of the driving roller, based on the engagement with the driving roller, and a load device for applying a resistance to the driven shaft against the rotation, wherein the driving shaft is fixed in position and the driven shaft is supported so as to move to and from the driving shaft, and a press apparatus is used to force the driven shaft to the driving shaft for measurement operation, and the driven shaft is positioned lower than the driving shaft in height, and the traction force acting on the engagement portion between the driving roller and the driven roller is directed in a direction to push the driven shaft downward.
