PROBLEM TO BE SOLVED: To provide a vehicle power supply device in which a power supply unit and a fuse can be connected with each other without using a power cable, and the fuse can be easily connected to each system of the power supply unit and fixed even when the power supply unit has a plurality of systems.SOLUTION: A plurality of first voltage terminals 6 of a DC/DC converter 3 are provided on a lateral face of a case 3a. A plurality of second voltage terminals 7 of a plurality of fuses 41 are provided in a lateral face of a fuse holder 4a. When a fuse holder module 4 is assembled to the DC/DC converter 3, the second voltage terminals 7 are simultaneously inserted into the plurality of first voltage terminals 6 respectively, and the first voltage terminals 6 and the second voltage terminals 7 are directly connected with each other. In an inner peripheral surface of each first voltage terminal 6, a projection part 62 is formed. A lock ball 94 protruded from a housing 91 holding the second voltage terminals 7 abuts on the projection part 62, and thereby, the case 3a and the fuse holder 4a are locked while the first voltage terminals 6 and the second voltage terminals 7 are connected with each other. |
