To provide a bar-shaped object pushing tool which is easy to assemble although having cassette type functions, which has no troubles with its actuating property since a very slender bar-shaped object suited for drawing fine lines during rotating operations advances straight without rotating, which has a guide pipe provided between the bar-shaped object and a front shaft to make a bar-shaped object receiving part very thin, which prevents damage to the bar-shaped object by the impact of drop or the like by allowing only little clearance between the outer wall of the bar- shaped object and the inner wall of the guide pipe, and which has good operability.
This pushing tool has a front shaft 1 provided rotatably with respect to a rear shaft 2 and formed with a rotation stopping means 1b thereinside, and an intermediate shaft 3 provided in such a manner as to have its rear projected into the end shaft 1 and to rotate along with the rear shaft 2 and having a spiral means 3a formed on its inner periphery. The pushing tool also has a guide pipe 4 provided inside the intermediate shaft 3 and having formed thereon a guide groove 4c along the longitudinal direction of its rear and provided with an engagement means which engages the rotation stopping means 1b of the end shaft 1 to lock rotation, and a slider 5 being slidable within the guide pipe 4 but having its rotation locked and having a bar-shaped object receiving part 5a at its tip.
