  • the writing component 1 has an intermediate portion 19 between the shoulder 10 and the large diameter portion 5.
  • the intermediate portion 19 is held elastically by a holding member 20 of the barrel 2.
  • the holding member 20 is generally conical-shaped and has slits 21.

  • a circumferential groove 30 is formed on the periphery of the front piece 22 for receiving a projection 29 of the barrel main body 23 to prevent detachment of the front piece 22 from the barrel main body 23.
  • the front piece 22 also has a longitudinal groove 32 for receiving a projection 31 of the barrel main body 23 to prevent relative rotation between the front piece 22 and the barrel main body 23.
  • the barrel main body 23 functions as a cap and also functions as a grip during a writing operation.
  • the barrel main body may have a multi-layer structure (not shown) wherein a basal portion is formed with a hard layer and the surface portion is formed with a soft layer by, e.g., two-color molding or an injection molding process.
  • a clip 33 is disposed on the outside of the barrel main body 23.
  • the barrel 2 is maintained at the housed position where the engagement portion 7 engages with the lock portion 6 of the writing component 1.
  • the writing tip 3 is housed in the airtight sleeve 9, the inner raised portion 11 is in contact with the shoulder 10, and the cap plate 15 is pressingly contacted to the slanted opening edge 13 by the projecting rib 17, whereby the inside of the airtight sleeve 9 is kept in an airtight condition and the writing tip 3 is prevented from drying.
  • the barrel is maintained at the writing position, and the user can perform a writing operation by gripping the barrel main body 23.
  • the engagement force at the lock portion 6 and the engagement portion 8 at this time is set to such a level that it can withstand the writing force.
  • the airtight sleeve 9 abuts on the inner side 16 of the barrel 2, the projecting rib 17 comes out of the window hole 18 and is in slidable contact with the inner side 16, and the cap plate 15 is pressed toward the slanted opening edge 13 and, as shown in Fig. 1, the airtight sleeve reaches the retracted position and holds the writing component 1 at the housed position.
  • the cap plate of the airtight sleeve is opened, and the writing tip of the writing component can be protruded from the aperture of the barrel at the time of writing. Further, when the barrel is moved forward from the writing position, the cap plate is rotated by the projecting rib and closes the bore of the airtight sleeve, whereby the cap plate surrounds airtightly the periphery of the writing tip and prevent the writing tip from drying.
  • the cap plate Since the cap plate is pressed against the slanted opening edge by the projecting rib, the pressing force can be transferred over the entire cap plate and the cap plate can be closely contacted to the opening edge securely and entirely.
  • the opening edge is slanted, the rotation of the cap plate can be made small as compared with the case where the opening edge is set at a right angle, and thus the stress exerted on the hinge is low and the durability is improved.
  • no special means, such as a spring is required to pressingly fit the cap plate, and the pressing force can always be imparted by means of the projecting rib, the overall structure of the writing instrument is simplified. Furthermore, since the number of parts of the writing instrument is reduced, it is possible to reduce the diameter of the barrel, assembly of the writing instrument is facilitated, and the writing instrument can be obtained economically.
