  • the first magnet 83 and the second magnet 53 have a magnetic field when the first connector 80 and the second connector 50 are connected.
  • the first magnet 83 is provided in the first connection terminal arrangement portion 81a
  • the second magnet 53 is provided in the second connection terminal arrangement portion 51a. In the vicinity of the first connection terminal 82 and the second connection terminal 52, a magnetic force acts in the direction of connecting the first connection terminal 82 and the second connection terminal 52, and an electrical connection can be achieved more reliably.
  • first connection terminal 82 is arranged so as to be sandwiched between the first magnet 83 and the second connection terminal 52 is arranged so as to be sandwiched between the second magnet 53, the first connection terminal 82 and the second connection are connected. Since the magnetic force acts to help the terminals 52 come into contact with each other on the surface, the first connection terminal 82 and the second connection terminal 52 can be reliably electrically connected without one-sided contact.
  • the first connector and 80 are provided with a third magnet 57 located on the opposite side of the second connector 50, and the third magnet 57 is a second magnet when the first connector 80 and the second connector 50 are not connected. Since they attract each other with 53, when the first connector 80 is pulled out from the second connector 50, the second magnet 53 of the second connector is attracted by the third magnet 57 to keep the second connector member 51 in the open state. be able to.
  • the stopper member 56 as an over-rotation prevention structure for preventing over-rotation is provided on the back side of the second connector 50, when the first connector 80 is inserted into the second connector 50, the second connector member 51 It can be maintained in an appropriate position where it can rotate under the load from the first connector 80.
  • the PCU 75 since the first connector 80 is provided on the PCU 75 and the second connector 50 is a connector connected to the battery 29, the PCU 75 can be easily connected to the connector connected to the battery 29. An electrical connection can be made reliably.
  • the second connector member 51 is rotated by the load inserted into the second connector 50 of the first connector 80, and the first connection terminal 82 and the second connection terminal 52 are connected to each other.
  • the crank mechanism, the link mechanism, etc. are made to work by the load of inserting the first connector into the second connector, and the first connector is seconded through these mechanisms.
  • the second connector may be moved in parallel toward the first connector so as to be electrically connected / disconnected so as to be different from the direction of insertion into the connector.
  • the left-right arrangement of the illustrated embodiment has been described, but even if the left-right arrangement is different, it is included in the present invention as long as it is within the scope of the gist of the invention.
