<P>PROBLEM TO BE SOLVED: To provide a retractable coater which has a relatively tough constitution, to which a bending part is not provided, and which does not require a space and can prevent the diameter of a shaft cylinder from increasing, can reliably open a cover body when pushing out a writing body and can reliably seal an opening upon storage of the writing body. <P>SOLUTION: The retractable coater is constituted such that upon advance operation of a shaft-like coating body 12, the shaft-like coating body 12 is made to advance, a protrusion 18c1 on the side part of the shaft-like coating body 12 is located on a front part in a long hole 34a, a connection member 32 is made movable to the front side, thereby, the back surface side of the cover body 16 is pushed by a coating part 14 and the cover body 16 is driven in the opening direction, and, on the other hand, upon retraction operation of the shaft-like coating body 12, the protrusion 18c1 on the side part of the shaft-like coating body 12 is made to be abut on a rear part in the long hole 34a, thereby, the connection member 32 is retracted to the rear side and the cover body 16 is made to perform a closing operation. <P>COPYRIGHT: (C)2010,JPO&INPIT |
