The pump unit (50) has a gripper portion (51) whose internal space is enlargingly and reducingly deformable by a gripping operation by an operator to feed the gas to the water storage tank (40). The adapter (30) has a drill-mounting portion (31b) for mounting on the core drill (1), a tank mounting portion (34) where the water storage tank (40) is mounted, a water passage (37) that connects between the drill-mounting portion (31b) and the tank mounting portion (34), and a valve unit (33) that opens and closes the water passage (37).
