PROBLEM TO BE SOLVED: To suppress rotation of a tire information acquisition device in a rubber pedestal in use.SOLUTION: A tire information acquisition device 10G with a rubber pedestal comprises a tire information acquisition device 10 having a sensor module 11A and a housing 11B, and a rubber pedestal 20 to which the tire information acquisition device 10 is attached and which is attached to a tire inner surface. The housing 11B of the tire information acquisition device with rubber pedestal has a tubular bottom part 12a and a cylindrical side wall part 12b for covering a side surface of the sensor module 11A. A length dimension lof one direction out of directions orthogonal to a tire radial direction measured from a center of a cylinder forming the side wall part 12b of the bottom part 12a is equal to or more than a radius of the cylinder, a length dimension lof the other direction out of directions orthogonal to the tire radial direction measured from the center of the cylinder is equal to or more than the length dimension lof the one direction, a maximum value L of a distance to a peripheral edge part of the bottom part 12a measured from the center of the cylinder is, when l=lis satisfied, L>l, and is, when l>lis satisfied, L≥l.SELECTED DRAWING: Figure 1
【課題】使用中にタイヤ情報取得装置がゴム台座内で回転してしまうことを抑止する。【解決手段】センサモジュール11Aと筺体11Bとを備えたタイヤ情報取得装置10と、タイヤ情報取得装置10を装着してタイヤ内面に取付けられるゴム台座20とを備えたゴム台座付きタイヤ情報取得装置10Gの筺体11Bが、板状の底部12aと、センサモジュール11Aの側面を覆う円筒状の側壁部12bとを備え、底部12aの、側壁部12bを構成する円筒の中心から測ったタイヤ径方向と直交する方向のうちの一方の方向の長さ寸法lbを、円筒の半径以上とし、円筒の中心から測ったタイヤ径方向と直交する方向のうちの他方の方向の長さ寸法laを、前記一方の方向の長さ寸法lb以上とし、かつ、円筒の中心から測った当該底部12aの周縁部までの距離の最大値Lを、la=lbのときにはL>laとし、la>lbのときには、L≧laとした。【選択図】図1
