PROBLEM TO BE SOLVED: To provide a tire ground contact state measurement device that can prevent damage of a measurement sheet for measuring a ground contact state of a tire even at a time of a high load.SOLUTION: A tire ground contact state measurement device comprises: a travelling surface 1; a tire driving device 2 that brings a tire T into ground contact with the travelling surface 1, and causes the tire T to roll; a measurement-purpose sheet 3 that is placed in a partial area of the travelling surface 1, and is for measuring a ground contact state of the tire T; a protection sheet 4 that covers the measurement-purpose sheet 3; and a back/forth tension addition mechanism 5 that applies tension along a tire onward movement direction MD to the protection sheet 4. The back/forth tension addition mechanism 5 has a back/forth tension adjustment mechanism that adjusts the tension along the tire onward movement direction MD so that the protection sheet 4 cancels out force to be received from the tire T along the tire onward movement direction MD.SELECTED DRAWING: Figure 2B

    【課題】高負荷時であってもタイヤの接地状態を測定する測定用シートの損傷を防ぐことができるタイヤの接地状態測定装置を提供する。【解決手段】走行面1と、走行面1にタイヤTを接地させ且つ転動させるタイヤ駆動装置2と、走行面1の一部領域に載置され、タイヤTの接地状態を測定するための測定用シート3と、測定用シート3を覆う保護シート4と、保護シート4に対してタイヤ進行方向MDに沿った張力を加える前後張力付加機構5と、を備え、前後張力付加機構5は、保護シート4がタイヤTから受けるタイヤ進行方向MDに沿った力を打ち消すように、タイヤ進行方向MDに沿った張力を調整する前後張力調整機構を有する。【選択図】図2B
