高になるなどの欠点があつた。 In such structures, there have been cases where the columnar protrusions that support the force of the coil springs have been deformed or damaged, or the springs have been dislodged from the protrusions. Also, if the spring constant is set small, the opening/closing operation will become unstable, and if the protrusion is made of strong material such as iron or the outer diameter of the protrusion is increased, the spring will be larger and the handle will also be larger. There were drawbacks such as high cost.

の先端部分を支持している。 Embodiments of the present invention will be described below based on the drawings. FIG. 3 shows an embodiment of the present invention, FIGS. 3a and 3b are both front views of the handle and essential parts, and FIG. 3c is a sectional view taken along the line Q-Q of FIG. 3a. In the figure, the same components as those shown in FIG. 2 are given the same reference numerals, and the explanation thereof will be omitted. This invention is based on a groove 3 in the columnar protrusion 3c shown in FIG.
A bridging portion 31 is provided extending from the side wall of the side wall a to connect the tip of the protrusion 3c to strengthen the protrusion 3c, and the coil spring 7 can be easily assembled to the handle 30 and the coil spring 7 can The bridging part 31 is arranged on the protruding part 3c so as not to come off the protruding part 3c, and the protruding part 3c and the bridging part 31 are integrally molded with the handle 30. That is, when the opening/closing mechanism and the tripping device (not shown) operate, the coil spring 7 operates between the direction of arrow 33 and the direction of arrow 34. During this operation, the hook portion 7a
The tip portion of the side plate 31 is made to slightly protrude from the end face of the bridging portion 31 as shown by dimension C, and the side plate 31 is formed with a width B smaller than the gap A between the hook portion of the coil spring 7 and the coil portion. Further, as shown in FIG. 3C, the bridging portion 31 has a protrusion 3c so that the coil spring 7 can smoothly expand and contract within the groove 3a.
