PROBLEM TO BE SOLVED: To provide an easily portable small-sized input device for tire management allowing data to be simply inputted in inputting data on the tire. SOLUTION: Since tire mounting positions (press-operation parts 18G to 18R) of a vehicle are displayed on an operation panel 16, a worker can simply select a tire on which data are to be inputted by viewing the operation panel 16. Further, since a plurality of letters and numerals can be inputted at each press-operation part, the area of the operation panel 16 can be minimized, and therefore miniaturization can be realized and also portability is enhanced.
