Wheel condition detector and wheel condition monitor
First Claim
1. A wheel condition detector that detects a condition of a wheel comprising:
- a case that is located in an internal space between a tire and a wheel member, the tire and the wheel member forming a wheel, wherein the case includes a detection space formed therein and includes a communication section that communicates the detection space with the internal space;
a condition sensor located in the detection space that detects a condition of the wheel; and
a restriction section that restricts an entry of foreign matter that exists in the internal space into the detection space through the communication section, wherein the restriction section includes a mode switching section that switches the communication section from a communication mode to a disconnection mode, if a preset condition, under which the foreign matter is expected to enter the detection space, is met.

Abstract
A wheel condition detector and a wheel condition monitor, each having a case provided in an internal space defined between a tire and a wheel member, the tire and the wheel member forming a wheel. The case has a detection space formed therein and a communication section for communicating an interior and an exterior of the detection space with each other. The wheel condition detector or the wheel condition monitor has: a condition sensor located in the detection space that detects a condition of the wheel; and a restriction section that restricts an entry of foreign matter present in the internal space into the detection space through the communication section.

10. A wheel condition monitor comprising:
-
a wheel-mounted device that is provided for a wheel and sends wheel information that indicates a wheel condition to a vehicle body; and a vehicle-mounted device that is mounted on the vehicle body and monitors the wheel condition based on the wheel information received from the wheel-mounted device, the wheel-mounted device comprising; a case located in an internal space defined between a tire and a wheel member, the tire and the wheel member forming a wheel, wherein the case includes a detection space formed therein and includes a communication section for communicating the detection space with the internal space; a condition sensor located in the detection space that detects a condition of the wheel; and a restriction section that restricts an entry of foreign matter that exists in the internal space into the detection space through the communication sections, wherein the restriction section includes a mode switching section that switches the communication section from communication mode to disconnection mode, if a preset condition, under which the foreign matter is expected to enter the detection space, is met. - View Dependent Claims (11)
