Abstract

A tire condition monitoring apparatus monitors the condition of a tire of a vehicle. A transmitter of the apparatus includes an installed portion, a casing, and arms. A tire condition detecting element is installed in the installed portion. The casing accommodates the installed portion. The installed portion is connected to the casing by the arms. The arms tolerate reactive force and protect the installed portion from that reactive force.

Claims

1. A transmitter of an apparatus for monitoring the condition of a tire of a vehicle, comprising:

an installed portion, wherein an element for detecting the condition of the tire is installed in the installed portion;

a casing, wherein the casing accommodates the installed portion; and

an arm, wherein the installed portion is connected to the casing by the arm, and the arm tolerates reactive force acting on the casing and protects the installed portion from that reactive force.

2. The transmitter according to claim 1, wherein the arm is formed integrally with the installed portion.

3. The transmitter according to claim 1, wherein the arm is one of two arms, and the arms are located at positions to form mirror images with respect to the installed portion.

4. The transmitter according to claim 1, wherein the arm has a substantially L shape.

5. The transmitter according to claim 1, wherein an attachment hole is formed in a distal end of the arm, a boss formed integrally with the casing is fitted in the attachment hole, and, in this state, a distal portion of the boss is deformed to a rivet-like shape.

6. A transmitter of an apparatus for monitoring the condition of a tire of a vehicle, comprising:

an installed portion, wherein an element for detecting the condition of the tire is installed in the installed portion;

a casing, wherein the casing accommodates the installed portion; and

an elastic arm, which projects from the installed portion, wherein the installed portion is connected to the casing by the arm.

7. The transmitter according to claim 6, wherein the arm is one of two arms, and the arms are located at positions to form mirror images with respect to the installed portion.

8. The transmitter according to claim 6, wherein the arm has a substantially L shape.

9. The transmitter according to claim 6, wherein an attachment hole is formed in a distal end of the arm, a boss formed integrally with the casing is fitted in the attachment hole, and, in this state, a distal portion of the boss is deformed to a rivet-like shape.
