Abstract

A tire valve unit includes a tire valve and a sensor unit. The tire valve includes a valve stem and a rubber body located on the periphery of the valve stem. The sensor unit includes a sensor mounted on a wheel and a housing that accommodates the sensor and is secured to the tire valve. The tire valve unit is mounted on the wheel by press-fitting the tire valve into a mounting hole in the wheel. The body includes an attaching portion. The tire valve includes an attaching projection that projects in the axial direction of the tire valve from the inside of the attaching portion toward the outside. The tire valve unit further includes a fixture that secures the attaching projection to the housing.

Claims

1. A tire valve unit comprising:

a tire valve including a valve stem and a rubber body located on a periphery of the valve stem, the tire valve including a first axial end and a second axial end; and

a sensor unit including a sensor that detects a condition of a tire mounted on a wheel and a housing that accommodates the sensor, and the sensor unit is secured to the tire valve, wherein

the tire valve unit is mounted on the wheel by press-fitting the tire valve into a mounting hole in the wheel from the first axial end,

the body includes

an opposed portion that is opposed to an inner surface of the mounting hole with the tire valve unit mounted on the wheel,

a proximal end portion located closer to the second axial end of the tire valve than the opposed portion, and

an attaching portion including the opposed portion and the proximal end portion,

the tire valve includes an attaching projection that projects in the axial direction of the tire valve from the inside of the attaching portion toward the outside of the attaching portion, and

the tire valve unit further includes a fixture that secures the attaching projection to the housing.

2. The tire valve unit according to claim 1, wherein

the housing includes an attaching wall including an attaching hole,

the attaching projection is inserted through the attaching hole and includes a groove at a part of the attaching projection that projects from the attaching wall, and

the fixture is fitted to the groove.

3. A tire valve unit comprising:

a tire valve including a valve stem and a rubber body located on a periphery of the valve stem, the tire valve including a first axial end and a second axial end; and

a sensor unit including a sensor that detects a condition of a tire mounted on a wheel and a housing that accommodates the sensor, and the sensor unit is secured to the tire valve, wherein

the tire valve unit is mounted on the wheel by press-fitting the tire valve into a mounting hole in the wheel from the first axial end,

the body includes

an opposed portion that is opposed to an inner surface of the mounting hole with the tire valve unit mounted on the wheel,

a proximal end portion located closer to the second axial end of the tire valve than the opposed portion, and

an attaching portion including the opposed portion and the proximal end portion,

the tire valve includes a first threaded member incorporated in the attaching portion, and

the tire valve unit further includes a second threaded member that is inserted in a through-hole in the housing and is screwed to the first threaded member.

4. A tire valve unit comprising:

a tire valve including a valve stem and a rubber body located on a periphery of the valve stem, the tire valve including a first axial end and a second axial end; and

a sensor unit including a sensor that detects a condition of a tire mounted on a wheel and a housing that accommodates the sensor, and the sensor unit is secured to the tire valve, wherein

the tire valve unit is mounted on the wheel by press-fitting the tire valve into a mounting hole in the wheel from the first axial end,

the body includes an attaching portion that is located closer to the second axial end of the tire valve than the portion located outside the tire with the tire valve unit mounted on the wheel,

the tire valve includes an attaching projection that projects from the inside of the attaching portion toward the outside of the attaching portion in the axial direction of the tire valve, and

the tire valve unit further includes a fixture that secures the attaching projection to the housing.
