1. A tire state quantity detecting apparatus provided in a tire for detecting a tire state quantity of the tire, comprising:
- a detector that is embedded in the tire, and that deforms by a force exerted from the tire, and that outputs a signal corresponding to a quantity of deformation of the detector; and
a reduction mechanism that is disposed between the tire and the detector, and that dynamically reduces the quantity of deformation of the detector with respect to a quantity of deformation of the tire, wherein the tire state quantity is detected based on the output signal of the detector.

Abstract
In a tire state quantity detecting apparatus, a detector that deforms by force exerted from a tire and that outputs a signal corresponding to the quantity of deformation is embedded within the tire. The detector is enclosed in a capsule within the tire, so that the quantity of deformation of the detector is reduced relative to the quantity of deformation of the tire.

12. A method of detecting a tire state quantity of a tire, comprising the steps of:
-
outputting a signal from a detector that is embedded in the tire, and that deforms by a force exerted from the tire, the signal corresponding to a quantity of deformation of the detector, wherein a reduction mechanism is disposed between the tire and the detector so as to reduce the quantity of deformation of the detector with respect to a quantity of deformation of the tire; and
determining the tire state quantity of the tire based upon the output signal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
