PROBLEM TO BE SOLVED: To provide a tire pressure detecting device comprising a pressure detecting sensor capable of always detecting proper pressure without being damaged and dropping off at the time of attaching/detaching a tire, on an automobile wheel. SOLUTION: A pressure detecting sensor 21 is fitted in a fitting groove 11 arranged on a thick-walled portion 10 of a rim portion 1 of an automobile wheel A, or fitted in a peripheral groove 12 arranged in a well portion of the rim portion 1. Therefore, the pressure sensor 21 is securely fixed to the wheel, and prevented from being damaged and dropping off at the time of attaching/ detaching a tire, so that proper pressure can be stably detected at all times. |
