Abstract: A spring part without increasing the total surface of the clip body. A part of the clip body is cut out as cutout part which is bent to form the spring part. The cutout part which is a part of the clip body is utilized as the spring part.

Abstract: The present invention provides a spring part without increasing the total surface of the clip body. A part of the clip body is cut out as cutout part which is bent to form the spring part. The cutout part which is a part of the clip body is utilized as the spring part.

Abstract: A clip fixing structure in which there is no possibility for producing a frictional scratch at an outer surface of a cylinder when it is fixed. The fixing section formed at the rear part of the clip section is bent along widthwise opposing sides and form to face at the rear surface as seen in a front elevational view of the clip section, and the fixing piece sections are provided with the engaging sections. Then, the clip set section formed at the cylinder is adapted to a forward or rearward size and a width size of the inner space of at least the fixing section, its part is protruded in a protruded shape becoming the fixing reference point where the fixing section is fitted, and both side surfaces of the clip set section corresponding to the engaging sections are provided with the holding sections for fixing and holding the fixing section to the clip set section.

Abstract: A clip fixing structure in which there is no possibility for producing a frictional scratch at an outer surface of a cylinder when it is fixed, its fixing is conveniently carried out, its productivity is improved and at the same time a loss of material is restricted, and it can be sufficiently adapted for its fixing to a high-class writing instrument.

Abstract: A clip body having upper and lower clamping pieces which flare continuously and from both ends of a bending portion in a desired width and a pressing cover having upper and lower clamping pieces continuously extending from both ends of a bending portion which is formed so as to provide a desired width, in which tops of the upper and lower clamping pieces are to be engaged with upper and lower parts close to the bending portion of said clip body, and a width formed between the tops being narrower than the maximum width formed between the upper and lower clamping portions of the clip body and wherein the pressing cover being slidably provided on the outer portions of the clip body so that both the upper and lower clamping pieces of the clip body approach each other in a pressing state.
