Description

  The present invention relates to an electronic device mounting structure for mounting an electronic device such as a transponder on the inner liner side of the pneumatic tire, and a pneumatic tire including the electronic device mounting structure.

  In recent years, in order to measure the internal pressure or the like of a pneumatic tire, an electronic device such as a transponder is often attached to the inner liner side of the pneumatic tire, and the electronic device is usually attached to the inner liner side as follows.

That is, a rubber pedestal is previously attached to the surface of the inner liner by vulcanization adhesion using a raw tire vulcanization process. Then, an adhesive is applied to at least one of the front surface of the rubber pedestal or the back surface of the electronic device (the back surface of the electronic device main body), and the electronic device is placed at a predetermined position on the surface of the inner liner. An electronic device is attached to the surface of the base by bonding. Alternatively, by placing the electronic device at a predetermined position on the surface of the inner liner and tightening a screw (see Patent Document 1), the electronic device is mounted on the surface of the rubber pedestal by a screw action (screwing action).

  By the way, when the electronic device is repaired, discarded, etc., it is necessary to remove the electronic device from the rubber pedestal and mount the repaired electronic device or another electronic device on the rubber pedestal.

  However, since the electronic device is attached to the surface of the rubber pedestal by bonding or screwing, it is troublesome or time consuming to attach / detach the electronic device to / from the rubber pedestal. For this reason, there is a problem that work such as repair and discard of the electronic device becomes complicated or takes a long time, and work efficiency such as repair and discard of the electronic device decreases.
