Casing structure of transmitter of tire condition monitoring apparatus

摘要

A transmitter in an apparatus for monitoring a condition of a tire attached to a wheel of a vehicle is fixed to the wheel such that the transmitter faces an outer circumferential surface of a wheel rim. The transmitter includes a circuit portion that detects the condition of the tire. The transmitter includes a casing that accommodates the circuit portion, and a leg that extends from the casing toward the outer circumferential surface of the wheel rim. The extended amount of the leg is adjustable such that the leg contacts the outer circumferential surface of the wheel rim when the transmitter is fixed to the wheel. Therefore, the transmitter is mounted to the wheel such that legs of the casing abut against the wheel rim regardless of the size of the wheel.
