A window hole through which the uneven surface of the terminal tube projects is formed on the side surface of the cylindrical holder that is fitted onto the terminal tube and is fitted onto the terminal tube freely in the axial direction to be fixed to the mating member. It has a structure in which locking teeth that mesh with the unevenness of the locking surface are formed on the surface corresponding to the window of the clip to be clamped, the tubular holder is fixed to the mating member, and the terminal tube is moved and adjusted in the tubular holder. After that, it has been proposed that the clip is clamped in a cylindrical holder and the terminal teeth are fixed by engaging the locking teeth with the unevenness of the locking surface protruding from the window hole. .

However, in the type in which the engaging teeth are engaged with the concavities and convexities of the engaging surface of the terminal tube as described above, the movement of the terminal tube can be adjusted only in one pitch unit of the unevenness, so that the desired position can be accurately adjusted. However, there is a possibility that a slight amount of extra tension may be applied to the cable or slack may occur on the cable.

As a means for solving the above problems, as a means for solving the above problems, the control cable terminal attaching device of the present invention is a control cable outer casing terminal in which an inner cable is slidably inserted in an outer casing. A terminal holder having an external thread formed on the outer periphery thereof is fitted into the cylindrical holder, which is fitted onto the terminal tube so as to be freely axially movable and fixed to a mating member, and is larger than its center hole, and , A female thread for locking, in which a fitting hole opened on one surface of the outer circumference is formed, and a female thread which is loosely fitted in the outer circumference of the terminal tube and which is engaged with the male thread of the terminal tube is formed on the inner circumference in the fitting hole.
