Abstract: A writing implement. A tubular outer shell (11) is provided outside a grip member (10), an inner shell (12) made of a soft material is provided entirely inside the outer shell (11), and the inner shell (12) is covered with the moderately hard outer shell (11). Thus, while the inner shell (12) inside can allow the user to feel the fit, the outer shell (11) outside prevents the inner shell (12) from getting damaged or worn even if the inner shell (12) is soft, so as to fully secure durability of the grip member (10). Since a thin part (11A) of the outer shell (11) is sufficiently thin on a swell (13), the excellent fit can be given to the user even if the outer shell (11) is formed of a hard elastic material to fully secure the durability of the grip member (10).

Abstract: A writing implement is provided including a knock mechanism, in which, without obstruction of normal operation, impact can be cushioned by a damper space that is sealed off from the outside. The writing implement (10) including the knock mechanism capable of advancing a writing tip (11) by push-out operation, includes: a holding section (12) for holding the writing tip (11); a shaft tube (20) for containing the holding section (12); a knock section (30) for covering a rear end portion of the shaft tube (20); a push-out section (13) for pressing the holding section (12) toward a front end in operative association with push-out operation of the knock section (30); and the damper space (40) provided between the knock section (30) and the shaft tube (20), being sealed off from the outside, and changing its volume by push-out operation of the knock section (30).

Abstract: A ballpoint pen body 1 has a convex portion 4 integrally formed on the outer surface 1a thereof, and a pair of shaft bodies 4a are formed on the convex portion 4. Receiving holes 5e are formed in a clip body 5 between the ball portion 5a and the operation portion 5b. With the shaft bodies 4a being received in the receiving holes 5e, the clip body 5 and the ballpoint pen body 1 are swingably coupled to each other. The receiving holes 5e are sized to be larger than the shaft bodies 4a, and the clip body 5 is allowed to move relative to the ballpoint pen body 1 being coupled to the ballpoint pen body 1. A leaf spring 6 is provided to urge the clip body 5 toward the ballpoint pen body 1.
