PROBLEM TO BE SOLVED: To provide a tire-ground contact state measurement device that can be miniaturized.SOLUTION: A tire-ground contact state measurement device comprises: a running surface 1; a tire drive unit 2 configured to let a tire T land on the running surface 1 and to drive the tire; a measurement sheet 3 that is mounted on a portion of the running surface 1 to measure the contact state of the tire T; a protective sheet 4 that covers the measurement sheet 3; and a front-to-back tension application mechanism 5 configured to apply tension on the protective sheet 4 along a tire traveling direction MD. The running surface 1 has a space 6 formed on at least either of a delay side and advance side of the measurement sheet 3 in the tire traveling direction MD to pull the protective sheet 4 toward below the running surface 1. The front-to-back tension application mechanism 5 includes a roller 50 disposed in each space 6, and is configured to pull at least one end of the protective sheet 4 in the tire traveling direction MD fixed to the roller 50 from below the running surface 1 by turning the roller 50.SELECTED DRAWING: Figure 2B
【課題】装置を小型化可能な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、走行面1には、測定用シート3のタイヤ進行方向MDの遅れ側及び進み側の少なくとも一方に、保護シート4を走行面1よりも下方に導く空間6が形成されており、前後張力付加機構5は、空間6内に配置されたローラ50を有し、ローラ50に固定された保護シート4のタイヤ進行方向MDの少なくとも一端を、ローラ50を回転させることで走行面1の下方から引っ張るように構成されている。【選択図】図2B
