An inverter (apparatus), to which two motors are connected, or a connecting structure of the inverter and the motors is made compact. A direct mounting connector to be directly mounted on an apparatus, includes: six independent busbars 21-26 for connecting the apparatus to two auxiliary machines for three-phase alternating current; two first terminal parts 11, 12 of U-pole, two first terminal parts 13, 14 of V-pole and two first terminal parts 15, 16 of W-pole of three-phase alternating current, altogether the six first terminal parts 11-16 being connected to the apparatus and formed at first ends of the respective six busbars 21-26, the two first terminal parts of the same pole are arranged adjacently to each other; and two sets 31-33 and 34-36, each set of which consists of a second terminal part of U-pole, a second terminal part of V-pole and a second terminal part of W-pole, altogether the six second terminal parts being connected to the two auxiliary machines and formed at second ends of the respective six busbars, the two sets being arranged adjacently to each other having a distance therebetween. The busbars 22, 25 include extended parts 22c, 25c extending between the two sets 31-33, 34-36 of the second terminal parts. The busbars 21-26 are molded in an insulating resin part.
