PROBLEM TO BE SOLVED: To provide a vehicular gauge capable of reducing heating of a diode, even in a simple constitution, under a predetermined condition.SOLUTION: A vehicular gauge comprises diodes 3 and 4 for parallely connecting a first power source supply circuit B1 via fuse F from an on-vehicle battery B and a second power source supply circuit B2 for electrically conducting when an ignition switch S is ON and respectively connected to the first and second power source supply circuits B1 and B2, an output terminal P for supplying electric power to external equipment K by using the electric power from the on-vehicle battery B supplied via these diodes 3 and 4, switch means 6 for switching the existence of supply of the electric power between the diodes 3 and 4 and the output terminal P and control means 9 for adjusting output from the output terminal P by controlling the switch means 6 on the basis of this determination result by determining an electric conduction state via the fuse F.SELECTED DRAWING: Figure 1 |
