To provide a vehicle information obtaining device capable of suppressing radio interference.
The vehicle information obtaining device 1 is provided with an information detection sensor 2 for detecting information of tires Ta-Td respectively; a transmission device 3 for transmitting the detection information detected by the respective information detection sensors 2 respectively; a receiving device 4 for receiving the detection information transmitted from the respective transmission devices 3 respectively and amplifying the received detection information; and an obtaining device 5 for obtaining the detection information amplified by the respective receiving devices 4. The respective information detection sensors 2 are mounted to respective wheels 10a-10d respectively, the respective transmission devices 3 are mounted to respective hubs 11a-11d, and the respective receiving devices 4 are mounted to respective knuckles 20a-20d for rotatably supporting the respective wheels 10a-10d and the respective hubs 11a-11d. Since a distance between the respective receiving devices 4 and the respective transmission devices 3 is made short, transmission output can be reduced and the detection information can be amplified.
