APPARATUS FOR PREVENTING NOISE OF STICK SPRING USING FOLD TYPE SEAT

摘要

The present invention relates to a noise prevention device for folding a sheet of spring stick , the insertion of the tube 14 the rod 12 and extending the coil spring by pulling output 16 provided to stick a spring 10 loaded on the sheet when folded in the 12 to the bottom of the rod 12 in the case of rotation in the axial direction having the piston seat 20 and toward the axial coil spring 16 in the rotation blocking member between ball bearing 30 or the protrusion 42 is a coil spring in the piston seat 20 formed through a rotation plate (40) (16) by blocking the rotational force is transmitted will be one direction to prevent the generation of friction noise of the coil spring .
