摘要： A mechanical pencil is constructed of (a) a decorative barrel to be held by a user; (b) a lead-feeding mechanism disposed within the decorative barrel; (c) a lead guide connected to the lead-feeding mechanism; (d) a lead-containing cartridge held detachably in the decorative barrel. The mechanical pencil according to the present invention can be continuously used by simply replacing a used-up cartridge with a fresh cartridge containing a plurality of writing leads. Thus, it is unnecessary, in contrast to conventional mechanical pencils, to insert a fresh supply of writing leads one by one into the mechanical pencil. Since a user is not required to touch writing leads directly, his hands are not smeared.

摘要： In a stick-shaped material propelling container capable of propelling and retracting a stick-shaped material, the influence of variation of the dimension of the stick-shaped material can be made small. An inner barrel (14) is slidably inserted in an outer barrel (12), an elastic body (16) which urges the inner barrel (14) rearward is provided between the inner barrel (14) and the outer barrel (12), a chuck piece (18) which holds a stick-shaped material is provided at a tip end portion of the inner barrel (14), and a chuck ring (20) is inserted between the chuck piece (18) and the outer barrel (12). A cross section of the stick-shaped material forms a triangular shape, the frictional force applying part (12b) which is in contact with the stick-shaped material to apply a frictional force is formed on an inner peripheral surface of the outer barrel (12), and the frictional force applying part (12b) abuts on a side in the vicinity of a vertex of the stick-shaped material in a cross section of the stick-shaped material.
