The device control unit 51 collates the identification information stored in advance in the memory with the identification information included in the response signal C. When the identification information matches (authenticates), the device control unit 51 outputs a first unlock signal to the control device 9. When the identification information does not match (non-authentication), the first unlock signal is not output.

  Further, when the user holding the portable device 11 grips the outdoor movable grip 23, when the user's hand touches the touch sensor 52, the device control unit 51 outputs a second unlock signal to the control device 9. . Note that when the touch sensor 52 does not detect contact with a human body, the second unlock signal is not output.

  When the control device 9 recognizes the input of the first unlock signal and the second unlock signal, it outputs a drive signal to the main electric lock 7. The main electric lock 7 controls the drive means based on the input drive signal, retracts the main-side dead bolt 70, and performs unlocking. When the main electric lock 7 is unlocked, the control device 9 outputs a drive signal to the sub electric lock 8.
