PURPOSE:To arrange effectively a spring in a jacket by providing the spring formed integrally with a coil spring and a linear spring prolonged from one end of the coil spring by one line body so as to miniaturize the entire spring. CONSTITUTION:The spring 50 is formed integrally by the coil spring 51 and the wire spring 52 prolonged from one end 51a of the coil spring 51 by one metallic wire such as piano wire. The spring 50 is fixed in the jacket 1 at the other end of the coil spring 51, the tip of the wire spring 52 of the spring is engaged with a shutter so as to activate the shutter in the close position with the bending force of both coil spring 51 and the wire spring 52. Thus, the spring is miniaturized and arranged effectively in a small space. |
