JP-A-8-258488 (FIGS. 7 and 8) Japanese Patent No. 3175933 (FIGS. 1 and 2)

  The problem to be solved by the present invention is to form the clip body of the writing instrument shaft cylinder, cap or other held body separately, incorporate the clip body into the held body, and urge the clip body in the holding direction with a holding spring. In the clip made to do so, it is not necessary to provide an insertion hole for inserting a protrusion or holding spring for holding the clip body into the held body, and it is to provide a clip that is easy to manufacture and assemble and is not easily broken, Another object of the present invention is to provide a clip that does not easily fall out even when the spring clamping force is insufficient.

  According to the present invention, a clip holder that holds the clip body in a swingable manner is provided, the leg piece is formed in a state of being opposed to the clip holder, and the engaging portion is formed on the outer surface of the leg piece. A base end of a leaf spring-like sandwiching spring that has a retaining hole, engages the engaging portion of the clip holder with the hole edge of the retaining hole, and biases the clip body between the leg pieces in the sandwiching direction. Is provided in a substantially inscribed state, and the above-described problems are solved.

  Further, according to the present invention, there is provided the above clip, wherein the clip has a retaining piece formed of a soft material on the inner surface of the clip body, and the tip of the retaining piece is inclined toward the clip holder. .

  Since the clip holder is formed separately from the object to be held, and the engaging portion is formed on the outer surface of the leg piece provided opposite to the clip holder, the clip spring is attached before the clamping spring is attached. The clip holder can bend the leg piece inward easily, and the engaging portion can be easily engaged with the hole edge of the retaining hole of the holder. After that, if the base end of the leaf spring-shaped clamping spring is inserted between the leg pieces in a substantially inscribed state, it becomes difficult to bend the leg pieces inward, and the clip holder and the held body are securely connected. And easy to assemble. Moreover, since a retaining hole should just be formed in a to-be-held body, manufacture is easy and can be obtained economically.

  An upright piece is formed in the clip holder so as to be inserted between both side walls of the clip body, and the clip body and the clip holder can swing on the inner surface of the side wall of the clip body and the outer surface of the upright piece. When the engaging portion to be connected is formed, when the engaging portions are engaged, the upright pieces are bent inward so that the engaging portions can be easily engaged with each other. By inserting one end of the holding spring in a substantially inscribed state, the upright piece is less likely to bend, so that the clip body and the clip holder can be easily and reliably connected.

  Furthermore, when a retaining piece made of a soft material with the tip inclined toward the clip holder is provided on the inner surface of the clip body, when inserting a fastening body such as paper or clothes between the held body and the clip body, It can be easily pinched, and after the pinching, the retaining piece becomes a resistance and can be made difficult to fall off in the pulling direction. In addition, if the retaining pieces are formed in a plurality of pleats, for example, even if a clip is sandwiched from a longitudinal direction or a lateral direction to a stationary body such as a notebook or notebook, it does not tilt or slide off. Therefore, it can be attached more reliably and can be prevented from being lost.
