Abstract
A writing tool is provided. An ink reservoir (7) and an ink supply passage (9) are formed in a barrel (1) provided with a brush body (2). Ink contained in the ink reservoir (7) is supplied to the brush body (2) via the ink supply passage (9). A wire (17) movably provided in the ink supply passage (9) is movably supported by a coiled spring (16). A ball (18) is provided in the ink reservoir (7). While the barrel (1) is being moved, the ball (18) collides with the coiled spring (16), thereby moving the wire (17).
