Etc., more preferably about 4 to 90 mm 2 ). That is, for example, even engagement in a small area of about 1 to 115 mm 2 means that strong engagement is achieved by a mechanical male-female structure or the like, which itself has a known structure.

- the color member used in the vulcanization molding process of the pneumatic tire of the present invention is removed from the tire after the vulcanization molding is completed. That is, when the tire is used, it does not become a constituent member of the tire. However, in the space formed between the protruding tip of the mechanical fastener member and the tire inner surface around the mechanical fastener member, the protruding tip of the mechanical fastener member and the mechanical fastener In order to physically protect the entire member, a detachable collar member may be loaded and used for distribution and storage of the tire.

- the thing of the comparative example 1 is a thing which does not use a color
- the shape in plan view of the concave flat surface area as in Example 1 is a track-and-track shape as shown in FIG.
- the depth d of the concave flat surface region is 0.3 mm
- the depth d of the concave flat surface region is 0.8 mm.
- the tire of Comparative Example 1 does not have a concave flat surface area.
- the test tire has a tire size of 195 / 65R15 (load 5 kN, air pressure 150 kPa), and in the form shown in FIG. 7B, a mounting object (housing) containing an air pressure sensor having a weight of 100 g and an electronic circuit including a transmitter.
- the body was attached to the tread portion on the inner surface of the tire, and the rotation of the casing was observed while running on a drum testing machine (running speed 80 km / hour, running time 20 hours).
- Example 1 and 2 products were both excellent in preventing rotation, and according to Examples 1 and 2, the radio wave reception rate was high and the casing was not damaged.
- the thing of the comparative example 1 had a low radio wave reception rate, the damage of the housing
- the machine in a pneumatic tire in which an object having specific functionality is attached to the inner surface of the pneumatic tire using a mechanical fastener member, the machine is moved along with the rolling of the pneumatic tire. It is possible to effectively prevent an object having a specific function attached with a target fastener material from rotating about the mechanical fastener material as a rotation center axis. As a result, the specific function of the object can be used with high durability and accuracy.

Abstract
Description
(1)タイヤ内面に、2つの部材に分離できる機械的留め具のうちの一方の部材を有し、該機械的留め具部材の周囲のタイヤ内表面に、その周辺部とは段差を有した凹部として形成された凹部平坦面領域を形成されてなることを特徴とする空気入りタイヤ。
(2)前記段差がタイヤ内表面の鉛直方向に0.5mm以上あり、かつ、タイヤ内面をその鉛直方向から平面視した場合に、前記機械的留め具部材の中心と前記凹部平坦面領域の輪郭線との距離が一定ではなく、変化しているものであることを特徴とする上記(1)記載の空気入りタイヤ。
(3)タイヤ内面をその鉛直方向から平面視した場合に、前記凹部平坦面領域の輪郭形状は、前記機械的留め具部材の中心を通るタイヤ軸方向線とタイヤ周方向線のいずれかまたは双方に対して非線対称であることを特徴とする上記(1)または(2)記載の空気入りタイヤ。
(4)タイヤ内面をその鉛直方向から平面視した場合に、前記凹部平坦面領域の輪郭形状は、鋭利な角部を持たず、曲率半径2mm以上の曲線または直線で構成されていることを特徴とする上記(1)~(3)のいずれかに記載の空気入りタイヤ。
(5)タイヤ内面をその鉛直方向から平面視した場合に、前記凹部平坦面領域の輪郭形状は、前記機械的留め具部材を中心に、タイヤ周方向とタイヤ軸方向の直交座標において、少なくとも一方の軸に対して線対称であり、略円弧と直線で構成された形状であることを特徴とする上記(1)~(4)のいずれかに記載の空気入りタイヤ。
(6)タイヤ内面にある前記一方の機械的留め具に係合するもう一方の機械的留め具を有する取付け物体を、それら2つの留め具を係合させることによりタイヤ内面に固定してなることを特徴とする上記(1)~(5)のいずれかに記載の空気入りタイヤ。
(7)タイヤ内面をその鉛直方向から平面視した場合に、前記取付け物体が前記機械的留め具部材を中心軸にして回転できる角度が10度以下であることを特徴とする上記(6)記載の空気入りタイヤ。
(8)前記もう一方の留め具を有する物体が、(a)センサーを含む電子回路、(b)バランスウェイト、(c)ランフラット中子、(d)脱酸素剤、乾燥剤および/または紫外線検知発色剤を塗布または搭載した物体、(e)吸音材のいずれか一つかまたはそれらの複数を組合せた物体であることを特徴とする上記(6)または(7)に記載の空気入りタイヤ。
実施例1、2、比較例1
凹部平坦面領域の形成の有無と、形成させたもの(実施例1、2)ではその深さdの相違により、取り付け物体の回転の有無を調べた。凹部平坦面領域の形成は、加硫成形の際に機械的留め具の加硫接合と同時にカラーを使用して行った(実施例1、同2)。比較例1のものはカラーを使用しないものであり、凹部平坦面領域は形成されていないものである。
