PURPOSE:To prevent a wheel from being affected adversely and its external view from being damaged by setting up a detector at a penetrating hole which communicate to the inner part of a type and reach the wheel hub. CONSTITUTION:The tubeless tyre 3 is mounted on the rim 2 of the wheel 1 and the penetrating hole 6 which communicate to the inner part of the tyre 3 and reach the hub 5 of the wheel 1 is formed at a part of the spokes 4 of the wheel 1. Detector A which operates by the variation of the inner pressure of the tyre is mounted on the hub 5 and communicates to the penetrating hole 6 through the auxiliary hole 8. Since this detector A is mounted on the hub 5 near the center of the wheel 1, the wheel 1 is not affected adversely. When the inner pressure of the tyre 3 decreases below the preset value, an alarm is given from the detector A. In addition, the lead wire 9 can be wired to the handle position of the driver. |
