必要となる。D. Problems to be Solved by the Invention The conventional devices shown in FIGS. 5 to 7 have the following problems. First, the common attachment body 37 is required because the reduction gear device 2+, the link mechanism attachment body 32, and the closing spring 29 are attached to the common attachment body 37. Second, since the closing spring 29 and the link mechanism mounting body 32 to which the closing cam 28 is pivotally mounted are separately attached to the common mounting plate 37, there is a gap between the closing spring 29 and the closing spring fixing frame 31. It is necessary to insert the adjustment plate 31a to adjust the closing spring set load. Thirdly, since the link mechanism mounting body 32 that pivotally connects the sprocket 25 connected to the closing cam 28 and the reduction gear 21 are installed separately, it is necessary to reduce the speed in order to adjust the slack of the chain 26. Means is taken to move the device 2I left and right in the figure in the case of FIG. 6, and up and down in the figure in the case of FIG. Fourth, in the case shown in Fig. 7, the direction of the closing spring 29 is changed to shorten the height, or if such a configuration is used, the closing spring mounting frame 3
6 to the common mounting plate 37,
Since a large force is applied to the mounting frame 36, the frame needs to have a strong shape and also requires support from the mounting legs.

When the closing spring 29 is open, the closing spring 29 is charged by transmitting the rotational movement of the reduction gear 21 to the large sprocket 25 via the small sprocket 22 and the chain 26 to rotate the closing cam 28. At this time, the retracted spring 29 is kept in a charged state by a hook (not shown) so that it is not released. When the energy storage state of the closing spring 29 reaches a predetermined value, the closing spring 29 is released so that the engagement of the hook (not shown) is released using a closing electromagnet (not shown) or the like. As a result, the input cam 28 rotates, and the link mechanism 18
is extended, and the releasing force is transmitted to the connecting rod 12 inside the case 5, fixing the vacuum interrupter 7 and closing the movable contacts 8a and 8b.
