To measure a physical quantity acting on a tread of a tire during traveling accurately.SOLUTION: A measuring device 1 includes: a rotatable drum 2 having a travel road surface 10 for allowing a tire T to travel; and at least one measuring device 3 for measuring a physical quantity acting on a tread Ta of the tire T. The travel road surface 10 includes: a first road surface part 11 to which the measuring device 3 is attached; and a second road surface part 12 which is disposed at a position different from that of the first road surface part 11 in a drum circumferential direction and has a frictional coefficient larger than that of the first road surface part 11.SELECTED DRAWING: Figure 3

    【課題】 走行中のタイヤの踏面に作用する物理量を正確に測定することができる。【解決手段】 タイヤTを走行させるための走行路面10を有する回転可能なドラム2と、タイヤTの踏面Taに作用する物理量を測定するための少なくとも1つの計測器3とを含む測定装置1である。走行路面10は、計測器3が取り付けられた第1路面部11と、第1路面部11とはドラム周方向に異なる位置に配され、かつ、第1路面部11よりも摩擦係数の大きい第2路面部12とを含む。【選択図】図3
