PROBLEM TO BE SOLVED: To provide a cord-feeding mechanism of a bush cutter, in which, when the cord is worn, it is easily replaced with a new cord.SOLUTION: A cord-feeding mechanism of a bush cutter comprises: an approximately flat disk-like upper lid in which cord-inserting holes are disposed on its outer peripheral edge in a mutually facing state an approximately flat disk-like lower lid detachably fitted and attached to the upper lid a cord-winding bobbin disposed in a space surrounded with the upper lid and the lower lid in a state energized with a spring and a bottom lid whose connection shaft is penetrated and detachably attached to the lower lid and the cord-winding bobbin. The cord-winding bobbin is integrally formed with a downward projected pressing portion, is disposed in a state capable of being rotated around a driving shaft and capable of being upward or downward moved in an axial direction, and is divided into upper and lower cord-winding portions on which the cords can be wound into two layers through a central division portion. Cord guide holes having a division guide means for vertically dividing cords are disposed in the central division portion of the cord-winding bobbin in a mutually facing state.
