发明名称 BALL-POINT PEN
摘要 <P>PROBLEM TO BE SOLVED: To provide a ball-point pen in which even if manufacturing variation arises, a resilient force of a spring can be easily accommodated, and moreover, a user can accommodate the spring to a favorite resilient force, and can get a favorite feeling of writing. <P>SOLUTION: The ball-point pen includes: a ball-point pen tip 2 in which a ball 21 is rotationably held at a front end; a holder 3 which holds a rear part of the ball-point pen tip 2; an ink housing tube 4 to which a rear end of the holder 3 is attached; and a spring 5 which biases the ball 21 ahead. The ball-point pen is configured such that a spring supporting member 43 which supports a rear end of the spring 5 is formed at the ink housing tube 4, the holder 3 and the ink housing tube 4 are mutually rotationably screwed, and thereby a distance of an axial direction between a back surface of the ball 21 of a front end of the ball-point pen tip 2 and the spring supporting members 43 of the ink housing tube 4 can be regulated. <P>COPYRIGHT: (C)2012,JPO&INPIT
