PURPOSE: To make it possible to use spring characteristics in various forms, by connecting both ends of an astride legs grip to a compression spring and connecting the rotating support by a snap method. CONSTITUTION: The synthetic resin pin is composed of two legs 2 and 3 and connected to astride legs grip 4 and 5 respectively and the ends of the astride legs grip are connected to a compression spring 6. The compression spring forms substantially U-shape and located inside of the astride legs grip. The rotating support 7 is located between the legs and the astride legs grip, which can be connected by a snap method. In the above structure, this pin can be manufacture by simple tools and obtain better spring characteristics by making the compression spring as the U-shape. |
