  • the support member 82 supports the pressing piece 88 so that it can move back and forth between the standby position and the approach position, so that the biasing member 86 can be supported between the support member 82 and the pressing piece 88.
  • the connection work of the coil end drawer terminal 58 and the outer bus bar terminal 38 can be easily performed.
  • the pressing piece 88 has a pressing plate portion 88a and a guide portion 88g, when the coil end drawing terminal 58 is placed on the pressing piece 88, the tip of the coil end drawing terminal 58 can be placed on the pressing plate portion 88a while being pressed against the guide portion 88g. This makes it easy to place the tip of the coil end drawing terminal 58 on the pressing plate portion 88a.
  • the coil end lead-out terminal 58 is inserted into the terminal block body 72 through the inner opening 73h1 and placed on the connection member 80.
  • the outer bus bar terminal 38 is inserted into the terminal block body 72 through the outer opening 73h2 and placed on the coil end lead-out terminal 58.
  • the coil end lead-out terminal 58 and the outer bus bar terminal 38 are kept in contact with each other by the connection member 80.
  • connection direction of the outer connector 39 to the external connector 78 is set to be along the insertion direction of the outer bus bar terminal 38 to the outer opening 73h2
  • connection work of the outer connector 39 to the external connector 78 and the outer bus bar terminal 38 can be easily performed by connection work in the same direction.
  • the wiring 60, 62 connected to the outer terminals 79t1, 79t2 of the external connector 78 passes through the terminal block body 72 so as to face the inside of the device case 41. This makes it easy to incorporate signal wiring into the rotating electric machine 40.
  • the terminal block module 70 also supports the speed sensor internal connector 74 and the temperature sensor internal connector 76 so that they are positioned within the device case 41. Therefore, when the terminal block main body 72 that holds the connection member 80 is fixed to the device case 41, the speed sensor internal connector 74 and the temperature sensor internal connector 76 are positioned within the device case 41. Then, when the connectors for signals within the device, i.e., the connectors 106, 112 of the sensors 100, 110, are connected to the speed sensor internal connector 74 and the temperature sensor internal connector 76, the internal signals can be output outside the rotating electric machine 40 via the signal wiring 60, 62. In this way, the signal lines incorporated within the rotating electric machine 40 can be easily connected to wiring outside the rotating electric machine 40.
  • the rotating electric machine connection device 28 is applied as a connection device between a first terminal and a second terminal, rather than to a rotating electric machine 40, the first terminal supported by a cantilever can be pressed against the second terminal by a biasing member to connect the first terminal and the second terminal. This makes it possible to more reliably connect the terminals together without supporting the first terminal with a complex movable structure or connecting a braid or the like for movement. This further simplifies the terminal connection structure.
