PROBLEM TO BE SOLVED: To provide an electric lock having enhanced safety with a plurality of electrically retractable dead bolts or the like and being capable of constructing a power supply part having many batteries without excessive enlargement of the external shape of the lock.SOLUTION: An electric lock including a main lock 2 and a sub-lock 3 is mounted in a cavity part for accommodation. The main lock 2 and the sub-lock 3 have a lock case in which a lock mechanism part, a motor 72, a control board, and power supply parts 35a and 35b are housed. The power supply part 35a of the main lock 2 includes four batteries 76 which are series connected to generate a direct current voltage of 6 volt. The power supply part 35b of the sub-lock 3 also includes four batteries 76 which are series connected to generate a direct current voltage of 6 volt. The power supply part 35a of the main lock 2 and the power supply part 35b of the sub-lock 3 are parallel connected to constitute a power supply having a voltage of 6 bolt and a capacity of the two batteries 76. The power supply is once inputted to the main lock-side. The power is supplied to the sub-lock-side 3 from the main lock-side through power lines 86 and 87. |
