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.
