Since the electric charge is accumulated in the-, the insertion port 35 of the receiving lock 36
The insertion portion 6a of the key body 6 is pulled out from both terminals 10a,
Even if the electrical connection between 10b is cut off, the LED lamp 12
Since the light emission of is continued for a predetermined time, the user can confirm the locking operation even after the predetermined time elapses after going out.

Further, the case body 2 molded with an insulating resin
Has a key mounting opening 8 for detachably mounting the grip portion 6b of the key body 6 at one end, and a battery mounting opening 2 for removably accommodating a battery holder 4 holding a power supply battery 5 at the other end.
