<P>PROBLEM TO BE SOLVED: To provide a pivoted shaft structure of hairdressing scissors having a moving blade rotatably pivoted at a round shaft of a bolt and a static blade non-rotatably pivoted at a rectangular shaft of the bolt and having a coil spring installed between a nut threadably fitted to the bolt protruding out of the static blade and the static blade, wherein even if a slight clearance is present between the rectangular shaft of the bolt and a rectangular hole of the static blade, the static blade is neither loosened nor slanted in respect to the bolt to prevent it from opening, so that its sharpness can be improved and the scissors can be smoothly opened or closed. <P>SOLUTION: A concave portion 14 is formed at a static blade 11 and a rubber bushing 21 having an inner diameter smaller than an outer diameter of a threaded portion 13d is pushed into a threaded portion 13d of a bolt 13 within the concave portion, a long coil spring 22 having an inner diameter smaller than an outer diameter of the bushing 21 in a non-compressed state and having a natural length longer than an axial length of the bushing 21 is pushed outside of the bushing 21, and when a nut 23 is screwed into the threaded portion to cause the coil spring 22 to be compressed, the coil spring 22 is press contacted with a peripheral surface of the concave portion to cause the bolt 13 and the static blade 11 to be integrally assembled. <P>COPYRIGHT: (C)2013,JPO&INPIT |
