Abstract

An installation structure for an electronic component for a tire, where a case for the electronic component attached to a rim well portion can be prevented from being destroyed during attachment and removal of the tire to and from a wheel. In the installation structure, the electronic component received in the case is attached to the rim well portion in a tire air chamber. When the case is subjected to external force applied in the radial direction of the tire, the case is positionally released from a fixed state before it is destroyed by the force.

Claims

1. An installation structure for an electronic component for a tire, in which the electronic component received in a case is attached to a rim well portion in a tire air chamber, characterized in that an attachment force of the case to the rim well portion is set to be smaller than a breaking stress of the case so that, when the case is subjected to an external force applied in an axial direction of the tire, the case is separated from the rim well portion before the case is destroyed by the external force.

2. An installation structure for an electronic component for a tire, in which the electronic component received in a case is attached to a rim well portion in a tire air chamber, characterized in that a base is previously attached to the rim well portion, the case is attached to the base, and an attachment force of the base to the rim well portion is set to be smaller than a breaking stress of the case, so that when the case is subjected to an external force applied in an axial direction of the tire, the base is separated from the rim before the case is destroyed by the force.

3. An installation structure for an electronic component for a tire, in which the electronic component received in a case is attached to a rim well portion in a tire air chamber, characterized in that a base is previously attached to the rim well portion, the case is attached to the base, and a mechanical strength of the base is set to be lower than a mechanical strength of the case, so that when the case is subjected to an external force applied in an axial direction of the tire, the base is deformed or destroyed before the case is destroyed by the force, and the case is separated from the base.

4. An installation structure for an electronic component for a tire, in which the electronic component received in a case is attached to a rim well portion in a tire air chamber, characterized in that a base is previously attached to the rim well portion, the case is attached to the base by means of a binding member, and a mechanical strength of the binding member is set to be lower than a mechanical strength of the case, so that when the case is subjected to external force applied in an axial direction of the tire, the binding member is deformed or destroyed before the case is destroyed by the force, and the case is separated from the base.

5. An installation structure for an electronic component for a tire, in which the electronic component received in a case is attached to a rim well portion in a tire air chamber, characterized in that a base is previously attached to the rim well portion, the case is attached to the base by means of a fitting mechanism, the fitting mechanism allows only a slide of the case in an axial direction of the tire, and fitting of the base and the case is released by the slides, so that when the case is subjected to an external force applied in an axial direction of the tire, the case is separated from the base before the case is destroyed by the force.
