  Further, the end portion of the locking end portion 41 on the insertion side of the wire cable 42 has a projection portion 44 for hooking a jig, which is used in the cable pre-tensioning process, on the outer peripheral surface thereof. The protruding portion 44 is formed in a circumferential shape coaxially with the locking end portion 41.

[Fastening operation]
The fastening operation of the fastening member of the control cable of this embodiment will be described with reference to FIGS. 9 and 10.

  The locking end 41 of the cable 40 is inserted from the insertion hole 21 of the fastening body 20, and the E-ring 412 having a larger outer diameter than the insertion hole 21 in the space 27 is formed at the distal end of the locking end 41. Is fixed (see the axial sectional view of FIG. 10). Further, a detent nut (not shown) or the like can be used instead of the E ring 412.

The key member 30 is housed in the axial direction from the window hole 222 of the fastening body 20. At this time, since the convex portion 301 of the key member 30 protrudes outward from the surface 221 of the window hole 22, the elastic piece 361 is bent toward the gap 367 when the convex portion 301 is pressed relatively to the surface 221. Mu Then, as shown in the cross-sectional view of FIG. 9, the convex portion 301 of the key member 30 is fitted into the first groove-like portion 201 of the fastening body 20. This is the state of temporary insertion shown in FIG. 9, that is, the temporary insertion position. In the temporarily inserted state, the protrusion 338 of the key member 30 has a base protruding outward from the window hole opening 222. Therefore, even if the key member 30 is further pushed and pushed in the axial direction, the protrusion 338 Since the portion 338 hits the window hole 222, the key member 30 does not move downward any further. Further, in the temporarily inserted state, the urging spring 342 is in an extended state, so that the key member 30 is not pushed out of the window hole 22 by the urging force.

  In the temporary insertion state, pretension is applied to apply tensile load to both ends of the wire cable. When performing pre-tensioning, a hook for pre-tensioning (not shown) is hooked on the protrusion 44 at one end of the wire cable 42 from the wire cable 42 side, the other end of the wire cable 42 is fixed, and a tensile load is applied. . By performing pretensioning after assembling each component, the performance of the wire cable 42 can be stabilized and the bonding strength of each component can be confirmed.

  Thereafter, when the control cable is used in the transmission, the fastening portion 29 of the fastening member in the temporarily inserted state is fixed to the shift lever side and the other end is fixed to the transmission side.

Next, the locking end 41 of the cable 40 is slid in the axial direction within the insertion hole 21 to adjust the length of the cable 40. At this time, the sliding distance of the locking end portion 41 is regulated by the space portion 27. When the cable 40 has an appropriate length, the operation portion 318 is bent toward the space portion 317 by pressing both ends from above the key member 30, and the projection portion 338 is moved inward from the window hole 222. Then, the key member 30 is inserted in the axial direction in the state as it is, and the convex portion 301 of the key member 30 is fitted into the second groove-like portion 202 of the fastening main body 20 and at the same time, the protrusion 338 is engaged with the engaging groove 228. Engage with. Thus, the female screw 311 of the key member 30 and the male screw 411 of the cable 40 are locked. When the female screw 311 and the male screw 411 are locked, the cable 40 is fixed to the fastening member of the present invention while maintaining a desired length. This is the state of the main insertion shown in FIG. 10 , that is, the lock position .

  In the state of this insertion, the four protrusions 313 of the key member 30 are fitted into the recesses 223 of the fastening body 20. Thereby, it is possible to prevent the key member 30 from rattling in the window hole 22. Further, since the protrusion 338 of the key member 30 engages with the engagement groove 228 of the fastening body 20 and the operation portion 318 is not operated, the engagement cannot be released, and thus the key member 30 can be prevented from coming off. Further, the key member upper seat 340 and the biasing spring 342 are accommodated in the space 220 of the fastening body. In addition, the fastening body 20 and the key member 30 after this insertion have the end surface of the ceiling part 31 and the leg part 36 on the same circumference as the side surface of the fastening body 20, there is no protruding part, and the whole fastening member is a cylinder. It becomes a shape.

When changing from the temporarily inserted state to the fully inserted state, the key member 30 is not sufficiently pushed in the axial direction, and the protrusion 338 of the key member 30 and the engagement groove 228 of the fastening body 20 are completely formed. When not engaged, the key member 30 is pushed back in the direction of the temporary insertion position by the biasing force of the biasing spring 342. Thereby, it can be immediately determined whether the key member 30 and the fastening main body 20 are in an engaged state or incompletely engaged state.

In order to return to the temporary insertion state again from the main insertion, the operation portion 318 is bent toward the gap 317 by pressing both side surfaces of the key member 30 from the chamfered portion of the window hole opening 222. When the side surface of the key member 30 is bent toward the gap 317, the engagement between the protrusion 338 and the engagement groove 228 is released, and therefore, when the key member 30 is extracted from the fastening body 20, a temporary insertion state is obtained. .

[Key material]
FIG. 14 is a perspective view of the key member of the fastening member of the control cable of the present invention.

  In the control cable fastening member of this embodiment, the key member 60 is made of glass fiber reinforced nylon resin. The key member 60 is U-shaped as a whole, and has a ceiling portion 61 having an outer surface having the same radius of curvature as the outer peripheral surface of the cylindrical member 58 of the fastening body 50, and two linearly extending from the ceiling portion 61. The leg portion 66 is formed. The end surface of the leg portion 66 is on the same circumference as the outer surface of the ceiling portion 61. A female screw 611 is formed on the inner peripheral surface of the U-shaped key member 60, that is, the inner peripheral surface of the space formed by the ceiling portion 61 and the two leg portions 66.

  The side surfaces of the two leg portions 66 forming the outer surface of the key member 60 each have a convex portion 601 having a semicircular cross section that protrudes outward. The convex portion 601 is fitted to the first groove-like portion 501 and the second groove-like portion 502 of the fastening main body 50. That is, the first lock part 501, the second groove part 502, and the convex part 601 constitute a main lock part. The convex portion 601 is positioned at the tip of the elastic piece 661 having a shape cut out in a thin piece shape from the side surface of the leg portion 66. The elastic piece 661 is thin and has a gap 667 around the elastic piece 661. Therefore, when a force is applied to the convex portion 601 located at the tip of the elastic piece 661, the elastic piece 661 bends toward the gap 667. Mu

  Moreover, each side surface of the leg part 66 has the protrusion part 613 extended on the outer surface of the ceiling part 61 at both ends.

  The U-shaped side surface of the key member 60 has a protrusion 638 having a square cross section. The side surface having the projection 638 is a plate-like operation unit 618 cut out in a thin piece, and a gap 617 is provided vertically from the ceiling 61. Since the operation portion 618 is bent when a force is applied toward the gap 617, the protrusion 638 is moved by moving the operation portion 618. The protrusion 638 engages with the engagement groove 558 of the fastening main body 50. That is, the operation portion 618, the protrusion 638, and the engagement groove 558 constitute a sub lock portion.

[Fastening operation]
The basic fastening operation of the present embodiment is the same as that of the first embodiment. In the first embodiment, the upper seat 340 provided on the key member 30 is biased, whereas in the present embodiment, the four protrusions 613 of the key member 60 are biased.

Therefore, when the temporary insertion state is changed to the main insertion state, the key member 60 is not sufficiently pushed in the axial direction, and the protrusion 668 of the key member 60 and the engagement groove 558 of the fastening main body 50 are formed. When not completely engaged, the key member 60 is pushed back toward the temporary insertion position by the biasing force of the biasing spring 542 (not shown). Thereby, it can be immediately determined whether the key member 60 and the fastening main body 50 are in an engaged state or incompletely engaged state.
