To make difficult an illegal change of the stored running distance integrated value, in a running distance integrating meter having a non-volatile memory for storing a running distance integrated value.
This running distance integrating meter for a vehicle includes an ECU 16 for a meter for controlling the operation of a liquid crystal display panel 15 so that the running distance integrated value of the vehicle is displayed according to the storage content of an EEPROM 18. The ECU 16 for a meter is enciphers the running distance integrated value taking a combination of input levels to a plurality of ports P1 to Pn provided on a microcomputer 17 of the ECU 15 for the meter as a parameter, and the enciphered integrated value is stored in an EEPROM 18. In the case of displaying the integrated value, the enciphered integrated value taking a combination of the input levels to the plurality of ports P1 to Pn as a parameter is decoded, and a display is made according to the decoded integrated value.
