PROBLEM TO BE SOLVED: To provide an unlocking device allowing automatic interruption of energizing to a motor at an initial position and a full stroke position, holding of a reciprocating member at the full stroke position for prescribed time and freely measuring of timing for returning the reciprocating member to the initial position. SOLUTION: This unlocking device has an operation switch, the motor, the reciprocating member 3 performing a reciprocating linear motion between the two positions, first and second electric conductors 12 and 13 connected to the reciprocating member 3, and first and second terminals 15a, 15b, 16a and 16b disposed to be approachable/separable to/from the first and second electric conductors 12 and 13. The first electric conductor 12 and the first terminals 15a and 15b are in contact with each other at the initial position. The first and second electric conductors 12 and 13 and the first and second terminals 15a, 15b, 16a and 16b are in contact with each other to maintain an energizing state at an intermediate position. The second electric conductor 13 and the second terminals 16a and 16b are in contact with each other to interrupt the energizing at the full stroke position. When the reciprocating member 3 is returned to the initial position, the second terminals 16a and 16b and the second electric conductor 13 are separated to interrupt the energizing.
