  • the substantially S-shaped flexible conductors 62 forming parts of the terminal 60 are accommodated in most of an upper area in the housing 30, the socket terminals 20A as the inner connecting portions of the terminals 60 are accommodated in a lower end part of the housing 30 and terminal insertion openings 45 are concentrically open directly before the socket terminals 20A.
  • Such a terminal block T1 is similarly mounted on the upper wall 2 of the transmission case 1.
  • one or more pin terminals p provided on the one or more respective wires, particularly on the tips of the enable wires at least partly are inserted into the one or more socket terminals 20A as the inner connecting portions in connecting the one or more, particularly three inner conductive members (particularly enamel wires) of the motor side to the inner connecting portions of the terminals 60, and the one or more, particularly three outer conductive members (particularly busbars) of the inverter side and the outer connecting portions 11 of the corresponding terminals 60 are connected particularly by bolting.
  • the motor and the inverter are directly coupled.
  • the flexible conductor 62 as the vibration absorbing portion is provided for the terminal 60 mounted in the terminal block T1
  • this vibration is absorbed by the flexible conductor 62 and the transmission thereof to the opposite conductive member side is suppressed.
