摘要： A chuck for a mechanical pencil, wherein a lead holding part (62) is formed with several teeth (63) for use in holding the lead under four-point or six-point contacted condition. In this manner lead dust discharging regions are made. The extremity end (41) of the lead supplying cylinder is abutted against the rear raised surface (601) of the flange part (6a) from the rear end side of the lead chuck, forced applied from both directions when the front raised surface (602) of the flange part (6a) receive the rear end of the resilient member (12) installed between it and the sleeve (7) are utilized and each of the chuck members (61) generates a flexing phenomenon and then the chuck members may perform an instantaneous expanding operation under this flexing force.

摘要翻译： 一种用于自动铅笔的卡盘，其中引线保持部分（62）形成有多个齿（63），用于将引线保持在四点或六点接触状态。 以这种方式制成排尘区域。 引线供给筒的末端（41）从引线卡盘的后端侧抵靠凸缘部（6a）的后凸起面（601），当前凸起面（602） 使用凸缘部分（6a）的接收件（其安装在其与套筒7之间的弹性构件12的后端），并且每个卡盘构件（61）产生弯曲现象，然后卡盘构件可执行 在这种弯曲力下瞬时膨胀的作业。
