PROBLEM TO BE SOLVED: To provide a tire information acquisition device which is configured to reduce an influence on a riding comfort performance and a high-speed durability performance of a tire.SOLUTION: A tire information acquisition device 1 includes a sensor module 3 equipped with a sensor 2 for acquiring information on a tire 30 and a support skeleton 5 which is installed on an inner surface of the tire for supporting the sensor module 3 and is made of rubber. The support skeleton 5 is hollow, and the sensor module 3 is mounted on the support skeleton 5 in a floating state with respect to the inner surface of the tire. In addition, to further reduce an influence on riding a comfort performance and a high-speed durability performance of the tire, a difference ΔP between an inner pressure Pof the tire and a pressure Pof a gaseous matter inside the support skeleton 5 is set in a range of 50kPa≤ΔP≤150kPa, and a thickness d of the rubber of the support skeleton 5 is set in a range of 0.8 mm≤d≤1.2 mm.SELECTED DRAWING: Figure 1

    【課題】乗り心地性能やタイヤの高速耐久性能への影響を少なくできる構成のタイヤ情報取得装置を提供する。【解決手段】タイヤ30の情報を取得するセンサ2を備えたセンサモジュール3と、タイヤ内面に設置されて、センサモジュール3を支持するゴム製の支持躯体5とを備えたタイヤ情報取得装置1において、支持躯体5を中空状とするとともに、センサモジュール3を、タイヤ内面に対して浮いた状態で支持躯体5に取付けた。また、乗り心地性能やタイヤの高速耐久性能への影響を更に少なくするため、タイヤの内圧P1と支持躯体5の内部の気体の圧力P2との差ΔPを、50kPa≦ΔP≦150kPaの範囲とし、支持躯体5のゴムの厚さdを、0.8mm≦d≦1.2mmの範囲とした。【選択図】図1
