摘要： A friction unit includes a friction piece and a retention portion, the friction piece being configured to allow generation of frictional heat to cause handwriting in thermochromic ink to undergo a thermochromic change and the retention portion being configured to allow retention of the friction piece and attachment to and detachment from a barrel or cap of a thermochromic writing instrument. The retention portion has a tubular side wall forming an internal space opening at least downward, the side wall has at least one vent hole formed to communicate with the internal space, and air is allowed to flow between the vent hole, the internal space, and the downward opening.

摘要： Cam faces 24a and 24b are continuously formed in a circle on upper and lower faces which are perpendicular to an axial direction of a rotatable cam 24 which constitutes a rotational drive mechanism 21. Elastic members 23b are formed integrally with a holder member 23 for rotatably supporting the rotatable cam 24 to extend in the axial direction, and the first fixed cam and second fixed cam 23c and 23d having a small number of cam faces at butts and tips of the elastic members are arranged to face each other via the upper and lower cam faces 24a and 24b of the rotatable cam 24. The rotatable cam 24 is retreated and moved forward in the axial direction by writing pressure applied to a writing lead to be rotationally driven in one direction and rotational motion of the rotatable cam 24 is transmitted to the writing lead.
