Helical body, helical conversion device and being entwined prevention device of helical body

摘要

Topic Forming helically, it obstructs the fact that it invades to inside the internal space of the helical body from the opening where the other helical body and the like which it adjoins to the center line direction in helical body such as expansion and contraction possible cirque code, was formed to the helical body.SolutionsBeing entwined prevention component 50, coiling is done the coil section the first arm the second arm 53 which is the other end of 52 which is one end of 51 which and coil section 51 and coil section 51 and, has the wire rod for the spring. It winds coil section 51, and direction electric wire when it becomes opposite to 2 and spring 10 is laid out inside the internal space of electric wire 2. In addition, with electric wire 2 we are united first arm 52 as one end side fixed component by the unity band 40 in the part near the top of coil section 11 of spring, 10 with electric wire 2 we are united by the unity band second arm 53 as the other end side fixed component in the part near the bottom of coil section 11 of spring 10 40.
