Abstract
A writing implement having a sleeve formed with a bore extending therethrough axially of the implement, a barrel inserted in the bore of the sleeve and retractably projectable forward from the forward end of the sleeve, and a closure so shaped as to close the forward end opening of the sleeve bore. At least the forward end portion of the sleeve and the closure are made of a magnetic material, and at least one of the sleeve forward end portion and the closure is formed by a magnet so as to attract the other. The closure is connected to the sleeve by a connecting member made of an elastic material so as to be movable between a position where the closure closes the forward end opening of the sleeve bore and a position where the closure opens the forward end opening to permit the barrel to project forward. The closure is biased by the connecting member toward the sleeve to a position where the closure is attractable by the sleeve.
