Abstract

A transmitter is attached to a wheel of a vehicle and transmits data indicating a condition of a tire of the vehicle. A mounting structure of the transmitter has a casing, a pin and a fastener cap. The casing accommodates the transmitter. The casing has a through hole. The pin is attached to the wheel and inserted into the through hole of the casing. The fastener cap is fastened to the pin such that the casing does not come off the pin.

Claims

1. A mounting structure of a transmitter for a tire condition monitoring apparatus, wherein the transmitter is attached to a wheel of a vehicle and transmits data indicating a condition of a tire of the vehicle, the mounting structure comprising:

a casing for accommodating the transmitter, wherein the casing has a through hole;

a pin attached to the wheel, wherein the pin is inserted into the through hole of the casing; and

a fastener fastened to the pin such that the casing does not come off the pin.

2. The mounting structure according to claim 1, wherein the pin is welded to the wheel.

3. The mounting structure according to claim 1, wherein the fastener is a cap, and wherein the pin is press fitted into the cap.

4. A mounting structure of a transmitter for a tire condition monitoring apparatus, wherein the transmitter is attached to a wheel of a vehicle and transmits data indicating a condition of a tire of the vehicle, the mounting structure comprising:

a casing for accommodating the transmitter;

an elastic member attached to the casing, wherein the elastic member has a through hole;

a pin attached to the wheel, wherein the pin is inserted into the through hole of the elastic member; and

a fastener fastened to the pin such that the elastic member does not come off the pin.

5. The mounting structure according to claim 4, wherein the casing is covered with the elastic member.

6. The mounting structure according to claim 4, wherein the elastic member has a mount portion and a plurality of inclined portions, wherein the transmitter is attached to the mount portion, and the inclined portions incline relative to the mount portion, wherein each incline portion extends from the mount portion toward the wheel such that a space is defined between the mount portion and the wheel, the space permitting the elastic member to be deformed.

7. The mounting structure according to claim 6, wherein the casing is attached to a part of the mount portion that is opposite from the space.

8. The mounting structure according to claim 6, wherein the casing is located in the space such that the casing is covered by the mount portion and the inclined portions.

9. The mounting structure according to claim 8, wherein a clearance exists between the casing and the inclined portions.

10. The mounting structure according to claim 6, wherein the mount portion has an opening.

11. The mounting structure according to claim 7, wherein the inclined portions include a first inclined portion and a second inclined portion, the second inclined portion extending from the mount portion to a direction away from the wheel, and wherein the second inclined portion covers the casing.

12. The mounting structure according to claim 11, wherein the second inclined portion is one of a plurality of second inclined portions, wherein the second inclined portions extend from opposite ends of the mount portion to approach each other, and wherein distal ends of the second inclined portions are spaced from each other.

13. The mounting structure according to claim 11, wherein a clearance is defined between the casing and the second inclined portion.

14. The mounting structure according to claim 4, wherein the pin is welded to the wheel.

15. The mounting structure according to claim 4, wherein the elastic member is a leaf spring.

16. The mounting structure according to claim 4, wherein the fastener is a cap, and wherein the pin is press fitted into the cap.

17. A mounting structure of a transmitter for a tire condition monitoring apparatus, wherein the transmitter is attached to a wheel of a vehicle and transmits data indicating a condition of a tire of the vehicle, the mounting structure comprising:

a casing for accommodating the transmitter;

a leaf spring attached to the casing, wherein a space exists between the leaf spring and the wheel, the space permitting the casing to be displaced relative to the wheel, and wherein the leaf spring has a through hole;

a pin attached to the wheel, wherein the pin is inserted into the through hole of the leaf spring; and

a fastener fastened to the pin such that the leaf spring does not come off the pin.
