PROBLEM TO BE SOLVED: To enable grease adherence to be resolved while maintaining the lock state of an operation device of a disconnector and reduce the occurrence of operation failures resulting from the grease adherence.SOLUTION: A lock out device 1 includes: a circular plate 10 which is provided at an operation shaft 100 operating a disconnector so as to be arranged coaxially therewith and has cutout parts 10a located at parts of an outer periphery; a lock lever 12 switching between a lock state where the lock lever 12 is engaged with the cutout part 10a to regulate rotations of the operation shaft 100 and a lock releasing state where the lock lever 12 is separated from the cutout part 10a to allow the rotations of the operation shaft 100; a pin 14 rotatably supporting the lock lever 12; and an electromagnetic solenoid 16a driving the lock lever 12 to switch the state of the lock lever 12 between the lock state and the lock releasing state. The pin 14 rotates independently from the lock lever 12 and further includes a rotation mechanism part 18 rotating the pin 14. |
