Abstract: A ball-point pen, wherein a cover member (6) is fitted to a joint member (3) connecting a writing tip (1) rotatably supporting a writing ball (2) at the tip thereof to an ink storage tube. When the cover member (6) is fitted to the joint member (3) along the outer peripheral surface thereof, a part of the cover member does not come within 0.2 mm (within the range of the chain double-dashed line) from around the writing tip. Thus, even if the accuracies of parts and assembly machines are dispersed, a problem with an existing ball-point pen wherein a cover member is brought into contact with a writing tip and the writing tip is damaged in an assembly step can be avoided.

Abstract: [Purpose] To provide a lead holding structure of a mechanical pencil where a predetermined lead holding force is maintained so that a lead does not move even if a writing pressure is repeatedly applied to the lead and where a so-called biting-off of a lead (break) is prevented without damaging the lead in repeatedly sending forward and backward operations. [Configuration] An outer periphery 5b of a chuck 5 corresponding to a lead holding section 5a is composed of a peripheral surface (horizontal surface) 5c and a peripheral surface (inclined surface) 5d. The peripheral surface 5c extends from substantially the center of the outer periphery 5b to its forward end and is substantially parallel to an axis or inclined toward the axis. The peripheral surface 5d extends from substantially the center backward and is a surface orthogonal to the axis or inclined toward the axis.

Abstract: An ink follower which has stable followability regardless of a pen body specification, a flow rate for writing and a writing speed and does not cause back leaking of the ink originating in shortage in the ink follower in the middle of writing and scattering of the ink follower by impact applied to the pen body and which does not flow out from the ink reservoir in storing the pen body at a high temperature and provides a stable flow rate for writing. An ink follower is also provided which prevents the ink from volatilizing by shutting off the ink from the outside air (volatilization preventing property) and which prevents the ink from leaking in writing with the pen turned upward. The ink follower, for example, contains a non-volatile or slightly volatile organic solvent and a non-styrene base thermoplastic elastomer which is soluble or swollen in the organic solvent and showing viscoelasticity which is predominant in elastic response.
