A change-speed construction for a fishing rod includes a hollow cylindrical shaft, and a control shaft that is movable within the cylindrical shaft between an outer position and an inner position. A key member is carried on a carrier, which is disposed axially and movably within the cylindrical shaft. A coiled small compression spring has two ends that are fastened respectively to the carrier and the control shaft. Two gears are sleeved rotatably on the cylindrical shaft. The key member is engaged within a keyway unit in one of the gears when the control shaft is located at the outer position, and within a keyway unit in the other one of the gears when the control shaft is located at the inner position. As such, the key member is urged by the small compression spring to move smoothly between the keyway units.
