PROBLEM TO BE SOLVED: To solve the problem of a combination of a lock lever 23 is more easily loosened, if the number of times of operation of interlocking increases, since a driving lever 26 is stopped with the lock lever 23 conventionally. SOLUTION: An interlocking mechanism for an integrated apparatus of a drawer type electrical apparatus unit 3 and a grounding switch, is fitted with a means, which links the lower end of a lock lever 23 and a stopper pin 9 which moves horizontally and converts the rotation of the lock lever 23 into insertion an withdrawal action of the stopper pin 9, an arm 21 which is composed, so that the driving lever 26 touches the underside of the tip of the stopper pin 9, rotates and moves by the positional change by insertion and withdrawal of the unit 3, a link 22 liked with the arm 21, a lock lever 23 to be locked or unlocked with the link 22, a twisting spring 24 for rotating the lock lever 23 in a counterclockwise direction, an attaching portion for attaching an operating handle 25 for operating the grounding switch manually, a driving lever 26 provided with a rod 27 for making and opening the grounding switch and a stopper portion 26c, and the stopper pin 9 which slides and is moved by the lock lever 23 horizontally. The stopper pin 9 is put in the middle of the lock lever 23 and the driving lever 26, to form a mechanism which prevents the force of the driving lever 26 from acting directly on the lock lever 23. |
