Claims
- 1. A mounting structure of a tire pressure sensing system in a tire pressure sensing system in which a pressure sensor is placed on a wheel to sense pressure of a tire which is mounted on the wheel,
wherein the wheel is a cast wheel for a vehicle including a rim portion where the tire is mounted, a hub portion provided at a center of the rim portion, and spoke portions connecting the rim portion and the hub portion, and the air pressure sensor is placed in a boundary portion between the rim portion and the spoke portions.
- 2. The mounting structure of a tire pressure sensing system according to claim 1, wherein a recessed portion having a shape recessed toward the hub portion is provided, and the pressure sensor is placed in the recessed portion.
- 3. The mounting structure of a tire pressure sensing system according to claim 1, wherein the pressure sensor is placed on an opposite side of an air valve which fills air to the tire.
- 4. The mounting structure of a tire pressure sensing system according to claim 2, wherein the pressure sensor is placed on an opposite side of an air valve which fills air to the tire.
- 5. The mounting structure of a tire pressure sensing system according to claim 1, wherein the pressure sensor is placed a side which is 180 degrees (+/−20 degrees) from the location of an air valve which fills air to the tire.
- 6. The mounting structure of a tire pressure sensing system according to claim 2, wherein collars are formed in the boundary portion, the tire pressure sensing system being mounted collars with fastening members.
- 7. The mounting structure of a tire pressure sensing system according to claim 2, wherein an insertion hole is formed in the boundary portion between the rim portion and one of the spoke portions, through which a detecting and transmitting unit is inserted into the recessed portion.
- 8. The mounting structure of a tire pressure sensing system according to claim 2, wherein the pressure sensor does not protrude into the tire and is lowered down into the spoke portions.
- 9. The mounting structure of a tire pressure sensing system according to claim 1, wherein pressure sensor is mounted on a stay, the stay having bent portions and which are formed ends thereof, the bent portions being welded to the rim portion.
- 10. The mounting structure of a tire pressure sensing system according to claim 9, wherein an escape hole is provided allowing a body portion of the pressure sensor to escape.
- 11. A mounting structure of a tire pressure sensing system in a tire pressure sensing system in which a pressure sensor is placed on a wheel to sense pressure of a tire which is mounted on the wheel,
wherein the wheel is a cast wheel for a vehicle including a rim portion where the tire is mounted, a hub portion provided at a center of the rim portion, and spoke portions connecting the rim portion and the hub portion, the air pressure sensor is placed in a boundary portion between the rim portion and the spoke portions, wherein an air valve which fills air the tire is positioned separately from the air pressure sensor.
- 12. The mounting structure of a tire pressure sensing system according to claim 11, wherein a recessed portion having a shape recessed toward the hub portion is provided, and the pressure sensor is placed in the recessed portion.
- 13. The mounting structure of a tire pressure sensing system according to claim 11, wherein the pressure sensor is placed on an opposite side of the air valve which fills the air to the tire.
- 14. The mounting structure of a tire pressure sensing system according to claim 12, wherein the pressure sensor is placed on an opposite side of the air valve which fills the air to the tire.
- 15. The mounting structure of a tire pressure sensing system according to claim 11, wherein the pressure sensor is placed a side which is 180 degrees (+/−20 degrees) from the location of the air valve which fills the air to the tire.
- 16. The mounting structure of a tire pressure sensing system according to claim 12, wherein collars are formed in the boundary portion, the tire pressure sensing system being mounted collars with fastening members.
- 17. The mounting structure of a tire pressure sensing system according to claim 12, wherein an insertion hole is formed in the boundary portion between the rim portion and one of the spoke portions, through which a detecting and transmitting unit is inserted into the recessed portion.
- 18. The mounting structure of a tire pressure sensing system according to claim 12, wherein the pressure sensor does not protrude into the tire and is lowered down into the spoke portions.
- 19. The mounting structure of a tire pressure sensing system according to claim 11, wherein pressure sensor is mounted on a stay, the stay having bent portions and which are formed ends thereof, the bent portions being welded to the rim portion.
- 20. The mounting structure of a tire pressure sensing system according to claim 19, wherein an escape hole is provided allowing a body portion of the pressure sensor to escape.
