<P>PROBLEM TO BE SOLVED: To provide a liquid feeding implement which uses a rotary cam mechanism for feeding liquid and smoothly feeds liquid with assistance of pressurizing action, the liquid feeding implement ensuring switching operation of the rotary cam mechanism. <P>SOLUTION: The implement includes a liquid storing tube 14 which is stored with liquid, is arranged movably in the axial direction in a barrel and which is provided with a point tip 32 movable to a position projected from the tip end of the barrel and to a position receded inside the barrel. The rotary cam mechanism 16 capable of moving the liquid storing tube 14 back and forth has a rotary cam 40 made movable between a forward position and a backward position, with a pressurizing space 18 provided in the rear part inside the rotary cam 40, wherein the pressurizing space 18 is able to pressurize inside the liquid storing tube 14 by being compressed when the point tip 32 is at the projected position. <P>COPYRIGHT: (C)2010,JPO&INPIT |
