Abstract: PURPOSE: A flexible cable hand-tool is provided to make a combine unit between a tip end portion and a handle of a T-shaped handle, a crank handle, and an extension bar as a flexible cable. CONSTITUTION: A tip end of a cable(1) inserted to a cable-inserting hole(7) of a dedicated tip(6) is pressed through the entire circumference. The other end is inserted to a pipe. Both the ends of the cable are pressed to a cable holding portion and the center portion is to a strong press portion. A shaft tube(12) of a handle inserted by the other end of the cable is fixed through the entire circumference and width. A flexible spiral tube covering the cable forms a cap of the handle side to a synthetic resin cap. The space between the cap and the handle is formed as an injection liquid passage and sealing unused. A strong stress is not worked on each wire organizing the cable but dispersed to the entire cable. Thus, a constricting torque and rotational force are delivered from the handle to the dedicated tip. The cable is twisted if the cable is long. To prevent the cable from twisting and to maintain the bent state, the flexible spiral tube omits a cap of the handle side and forms a cap during synthetic resin injection forming. The passage formed by making the synthetic resin injection passage thin is easily broken as the flexible spiral tube is twisted. Therefore, a sealing effect proves the non-use.
