Moving. When the fixing member 13 further moves toward the rear end of the terminal member 1, the holding portion 12 moves so as to be pinched toward the outer casing 2, and the fixing member 13 that slides or rotates on the holding portion 12 is pinched. It moves over the tip side convex part 221 of the part 12 and moves to the fixed position P1. Since the fixing member 13 is located at the fixing position P1 at the rear portion of the terminal member 1, it is possible to maintain the state in which the holding portion 12 made of a plurality of pieces holds the outer casing 2. Thereby, it can prevent that the outer casing 2 remove | deviates from the terminal member 1. FIG.

  Next, the procedure for attaching the terminal member 1 described above to the outer casing 2 will be described with reference to FIG. FIG. 4A shows a state in which the terminal member 1 is inserted through the insertion member 31, and FIG. 4B shows a state in which the terminal member 1 is removed from the insertion member 31. The insertion member 31 is a separate member from the terminal member 1, the outer casing 2, and the inner cable 3, and is provided at a predetermined location and has an insertion hole through which the terminal member 1 can be inserted.

  First, the outer casing 2 is disposed between the holding pieces 121 and 122 in a state where the inner cable 3 is inserted through the insertion holes of the contact portion 11 and the base portion 10. Subsequently, the outer casing 2 is clamped by the clamping pieces 121 and 122 with the tip of the outer casing 2 in contact with the contact portion 11 of the terminal member 1, and the terminal member 1 is positioned at the tip of the outer casing 2. In a state where the terminal member 1 is disposed at the tip of the outer casing 2, the terminal member 1 is inserted through the insertion member 31 from the front as indicated by the arrow in FIG. The insertion hole of the insertion member 31 has an inner diameter that is substantially the same as or slightly larger than the outer diameters of the distal end portion 14 and the connection portion 16.

  At this time, since the maximum outer diameter of the distal end portion 14 and the connection portion 16 is smaller than the outer diameter of the fixing member 13, the fixing member 13 held movably on the outer periphery of the base portion 10 has an insertion hole of the insertion member 31. It cannot pass through, and a load is applied by the outer wall of the insertion member 31. As a result, the fixing member 13 is detached from the holding portion 24, and the temporary fixing to the base portion 10 is canceled. As the terminal member 1 is inserted, the fixing member 13 moves to the fixing position P <b> 1 and the insertion member 13 is inserted. The hole and the tip side tapered surface of the tip side convex portion 221 come into contact with each other, and the pushing of the terminal member 1 is stopped. At this time, even when the outer diameter of the clamping part 12 that clamps the outer casing 2 is larger than the inner diameter of the fixing member 13 by the protrusion 23 on the inner peripheral side of the clamping pieces 121 and 122, the fixing member 13 reaches the fixing position P <b> 1. When moving, since the fixing member 13 presses the clamping part 12 inward, the protrusion 23 bites into the outer casing 2, and the terminal member 1 is more firmly fixed to the outer casing 2.

  If the terminal member 1 is fixed to the outer casing 2, the terminal member 1 is removed from the insertion member 31 (refer FIG.4 (b)). When the insertion member 31 is an attachment object to which the terminal member 1 is attached, the control cable is attached to the insertion member 31 as it is. Of course, the fixing member 13 can be positioned at the fixing position P1 without using the insertion member 31.

  As described above, according to this embodiment, the outer casing 2 is inserted through the insertion member 31 while pressing the outer casing 2 that is in contact with the contact portion 11 of the terminal member 1. Can be held by the holding portion 12. For this reason, the terminal member 1 can be fixed to the outer casing 2 by a simple operation. Therefore, the outer casing 2 can be reliably fixed to the terminal member 1 in a short working time.

  In the present embodiment, the contact portion is described as being formed at the rear end of the base portion, but the present invention is not limited to this, and the contact portion is formed separately from the base portion, and is formed at the rear end of the base portion. It may be connected.

  Further, in the present embodiment, the case where the sandwiching portion is divided into two pieces has been described, but the present invention is not limited to this and may be divided into three or more pieces.

  In the present embodiment, the fixing member is described as a ring shape, but the present invention is not limited to this, and for example, the fixing member may be C-shaped or U-shaped. Moreover, although the fixing member has been described as a resin or the like, the present invention is not limited to this, and may be a metal, for example. Further, the temporary fixing of the fixing member to the base portion is not limited to the connection by the holding portion, and may be fitting or loose fitting with a convex portion that protrudes radially outward of the base portion.

  Further, in the present embodiment, the case where the insertion member is formed with a through-hole is shown, but the present invention is not limited to this, and the insertion member may be a U-shaped slit that does not penetrate the hole.

  In the present embodiment, the outer casing has been described as an example of the long member. However, the present invention is not limited to this and may be a rod-shaped member such as a rod.

  In the present embodiment, the configuration in which the base portion is located at the tip of the terminal member has been described. However, the present invention is not limited to this, and a hook, a cover, or the like may be provided at the tip of the terminal member.

  The present invention is useful for securely fixing a long member to a terminal member.
