<P>PROBLEM TO BE SOLVED: To provide a ball-point pen having an enhanced assembly characteristics by relaxing dimensional accuracy required for an ink pressurizing member for pressurizing ink in a refill and a connecting member for returning the ink pressurizing member to a back end side by following a push-action member. <P>SOLUTION: The ink in the refill 3 is pressurized when the push-action members 10 and 11 are pressed down to a leading end side, and the pressurization of the ink in the refill 3 is released when the push-action members 10 and 11 are returned to the back end side. In this ball-point pen, the ink pressurizing member 8, which is moved to the leading end side so as to pressurize the ink in the refill 3 when the push-action members 10 and 11 are pushed down to the leading end side, is arranged on the back end side of the back end part 3b of the refill 3; and the connecting member 12 is provided in the state of connecting the push-action member 11 and the ink pressurizing member 8 together to return the ink pressurizing member 8 to the back end side in such a manner that the ink pressurizing member 8 follows the push-action member 11 when the push-action members 10 and 11 are returned to the back end side. <P>COPYRIGHT: (C)2007,JPO&INPIT |
