Abstract
A liquid supply implement can accommodate a large amount of liquid without being subjected to limitation of a capacity of a temporary storage chamber temporarily storing the liquid overflowing a tank, or can reduce the capacity of the temporary storage chamber. A tank formed inside a rear barrel and accommodating a liquid is divided into a plurality of tank portions. In order that all the tank portions do not communicate with a tip end supply element between the tank and a pen tip, any one of a plurality of through-holes of an inner plug respectively communicating with the respective tank portions is allowed to communicate with one through-hole formed in a lateral wall of a front barrel. By rotating the rear barrel with respect to the front barrel, selected tank portion can be switched.
