The moving part is formed in a structure connected to the tip 110 in order to contact the tip 110 to the lower surface of the upper plate 220 constituting the seismic isolation device 200 by a spring 140 which is operated by a button 120; As a bridge structure knitting amount measuring device 100 is configured to include,
The moving part 120 is formed between the tip 110 and the shaft 130, one side is connected to one end of the shaft 130, when the moving part is moved by the elastic force of the spring 140 surrounding the shaft It characterized in that to advance the tip 110 in a state connected with the shaft,
The shaft 130 is formed in the center in the longitudinal direction of the body constituting the bridge structure knitting amount measuring device 100 is fixed to one end of the moving part 120 and the other end of the spring 140 and the core 150 The moving path is formed, characterized in that formed in a structure passing through the center of the primary coil 160 and the secondary coil 170 formed spaced apart from the core 150,
The spring 140 is formed on the outer circumferential surface of the shaft 130 between the moving part 120 and the core 150, the outer surface of the body surrounding the spring 140 in the state that the spring 140 is the most condensed A button having a structure forming a step inside is formed to fix an area closest to the moving unit 120 among the springs 130. When the button is pressed, the step is removed by the elasticity of the spring as the step is removed. Bridge 120 protrudes from the body, and condensed again the spring 140, bridge structure knitting amount measuring device, characterized in that for reuse of the bridge structure knitting amount measuring device (100). delete delete delete delete
