要があり解除作業が困難となっていた。However, in the above-mentioned conventional structure, a coil spring for elastically urging the slider is required, and the slider and the coil spring are combined at the time of assembly.
Two parts had to be stored in the key points of the body, and workability was poor. On the other hand, in order to solve the above-mentioned problem, it is conceivable to provide the slider itself with an elastic piece for elastically urging the slider toward the fitting groove, but like the above-mentioned conventional configuration, the mounting direction of the slider on the body is There was no freedom in the mounting direction of the slider because it was limited to either from the fitting groove part or from the outer surface of the body, and for example, it tried to automate the mounting of the slider on the body. In this case, there is a problem in that the design of equipment for mounting work is restricted. Further, since the slider is always elastically biased in the direction of the fitting groove, in an electric device having many sliders when removing the electric device from the rail,
Since it is necessary to release the locked state of the plurality of sliders and the rail at the same time, the release work is difficult.

Therefore, the operation sensitivity of the switchgear 40 (that is, opening and closing). In order to prevent variations in the passing current of the main circuit when the device 40 operates, the amount of protrusion of the adjusting screw 62 screwed into the bimetal 61 from the bimetal 61 to the trip plate 44 side is adjusted. Will be required. Therefore, after assembly, the adjusting screw 62 is operated with the adjusting window 63 provided in the body 10 being opened. Meanwhile, the adjusting screw 62
Since it is not necessary to operate the adjusting screw 62 after adjusting once, the closing plate 64 closes the adjusting window 63 to inadvertently operate the adjusting screw 62 or foreign matter enters the inside of the body 10. Try not to.

And the overhanging piece 80a are engaged with each other, and the body 10 is fixed to the rail 80. When the slider 84 is pushed, it is necessary to overcome the elastic force of the elastic pressure piece 88 and overcome the ridge 89 over the protrusion 88a of the elastic pressure piece 88. And the protrusion 8
8a rides over the mountain portion 89 and the groove portion 88b of the protrusion 88a.
The rail 80 is held in a fixed state by the engagement of the crest 89 with the crest 89. In addition, even if a force is applied in this state such that the slider 84 is pulled out toward the outer surface of the body 10, the protrusion 88a is elastically biased laterally by the elastic pressure piece 88, so that a certain amount of force or more is exerted. As long as is not applied, the protruding portion 88a does not go over the mountain portion 89 and return to the release position, and the slider 84 is prevented from being released accidentally and the rail 80 falling from the body 10.

The degree of freedom in the direction can be increased, which is also advantageous when the slider 84 is automatically attached to the body 10. Further, the storage groove 83 is provided by the pressing piece 88.
Since the protrusion 88a is locked to the inner wall of the recess 83a of
The detachment of the slider 84 from the storage groove 83 can be reduced. In addition, the concave portion 83 formed in the storage groove 83
Since the mountain portion 89 is formed on the inner wall surface of the a close to the fitting groove portion 81 and the groove portion 88b that engages with the mountain portion 89 is formed on the protrusion portion 88a of the slider 84, when the body 80 is removed from the rail 80, Since the slider 84 maintains a stable position in a state where the mountain portion 89 formed in the concave portion 83a and the groove portion 88b formed in the protrusion portion 88a of the slider 84 are released from each other,
As shown in FIG. 7, even when the circuit breaker, which is an electric device, has a large number of sliders 84, the releasing work of the sliders 84 may be performed individually, which facilitates the releasing work, and the crests 89 and the grooves 88b. When and are engaged, the elastic force of the elastic pressure piece 88 against the movement of the slider 84 in the releasing direction exerts a force on the slider 84 in the direction of the fitting groove 81, and the slider 84 is inadvertently released. Can be prevented.

レール取付装置。1. A fitting groove portion, into which a rail having an overhanging piece protruding outwardly along the longitudinal direction from both sides is fitted, is provided on a bottom surface of a body of an electric device, and the rail is provided between the fitting groove portion and an inner bottom surface. One of the protruding pieces is fitted with a fitting protrusion protruding from one side wall of the fitting groove portion, and a slider for projecting movably in the fitting groove portion to lock the other protruding piece of the rail is provided. In a rail mounting device in which the slider is held in a state of being projected into the fitting groove portion, the other side wall of the fitting groove portion is communicated with the outer surface of the body, and the back side is wider than the opening side and at least the slider An accommodating groove for accommodating the slider is formed in the body so that the tip portion of the accommodating groove portion projects forward and backward, and a recess is formed on the inner side wall of the accommodating groove so that the cross-sectional shape of the slider corresponds to the cross-sectional shape of the accommodating groove. While making it almost the same, A rail mounting device characterized in that a slider is provided with a protrusion that is locked to both end walls of the recess according to movement of the slider, and an elastic piece that elastically presses the protrusion against the inner wall of the recess.
