Transmitter for tire state monitoring apparatus
First Claim
1. A transmitter for use in a tire state monitoring apparatus, wherein the transmitter transmits data indicating the state of a vehicle tire mounted on a wheel having an outer circumferential surface, the transmitter comprising:
- a valve stem having an axial direction and connectable to the wheel to which the tire mounts;
a circuit board on which a plurality of electric components are mounted to detect the state of the tire;
a casing for accommodating the circuit board in the tire, wherein the casing is positionable facing the outer circumferential surface of the wheel;
a connecting portion for connecting the casing to the valve stem pivotally about a line perpendicular to the axial direction of the valve stem; and
a pressing mechanism for pressing the casing toward the outer circumferential surface of the wheel to restrict pivoting of the casing.

Abstract
A transmitter for a tire state monitoring apparatus that is easily connected to a wheel in an optimal manner. The transmitter includes a valve stem connected to a wheel to which the tire is attached. Electric components are mounted on a circuit board to detect the state of the tire. A casing accommodates the circuit board in the tire. The casing faces toward an outer circumferential surface of the wheel. A connecting portion connects the casing to the valve stem pivotally about a line perpendicular to the axial direction of the valve stem. A pressing mechanism presses the casing toward the outer circumferential surface of the wheel to restrict pivoting of the casing.
