Insert it through the mounting hole
It is known that two nuts screwed into the screw of the terminal tube are clamped with a mating member sandwiched between them. However, since the nuts are tightened with a tool such as a spanner, tightening work should be done in a narrow space. It is difficult to perform, and when determining the axial mounting position of the terminal tube, it is necessary to adjust the position of the terminal tube while loosening or tightening both nuts, which is a troublesome work.

行なうことができる効果がある。The operation and effect of the present invention With the above-mentioned configuration, the tubular holder is fixed to the mating member with the locking member fitted in the retracted position separated from the claw piece, and the terminal tube of the end of the outer casing is tubular. After fitting in the shape holder and adjusting its axial position,
When the locking member is moved to the forward position, the locking member presses the claw piece to bend it at the easy-bending portion.
Since the claw pieces engage with the irregularities on the locking surface of the terminal tube and the terminal tube is fixed so that it cannot move in the axial direction, no tools are required and it can be installed if there is space to move the lock member. Therefore, it can be applied even in a narrow space and the range of use can be greatly expanded, and it is only necessary to insert the terminal tube into the tubular holder fixed to the mating member and move the locking member to the forward position. Therefore, the mounting work itself becomes extremely easy.When the terminal tube is positioned and mounted in the axial direction, the terminal tube is simply moved in the axial direction in the cylindrical holder to adjust the position, and the lock member is moved to the forward position. Since it can be moved, the positioning work can be easily performed.

びロツク部材28が一体的に組み付けられる。This embodiment has such a structure, and before mounting it on the mounting plate 10, first, each component is temporarily assembled for carrying in, and the procedure is as follows. After pushing in the fitting claw 30 from the rear side to the guide portion 20 of 12 until it fits into the positioning hole 22 on the rear side, and fixing it in the retracted position, the terminal coil 5 is covered with the compression coil spring 32,
The tip of the terminal tube 5 and the terminal of the inner cable 3 protruding from the terminal tube 5 are inserted into the insertion holes 13 of the tubular holder 12 while elastically retracting the retaining pieces 8 of the terminal tube 5, and the terminal of the inner cable 3 is tubular. While pulling out in front of the holder 12 and elastically compressing the compression coil spring 32 between the spring seat 9 and the cylindrical holder 12, the terminal tube 5 is pushed until the retaining piece 8 projects from the insertion hole 13.
The retaining piece 8 is locked to the edge of the insertion hole 13 of the cylindrical holder 12,
The terminal tube 5, the tubular holder 12, and the lock member 28 are integrally assembled in a state in which the terminal tube 5 is restricted from moving rearward by the restoring elastic force of the compression coil spring 32.

られる。When mounting on the mounting plate 10, as shown in FIG. 1, the fitting portion 14 of the cylindrical holder 12 is fitted into the mounting hole 11 of the mounting plate 10 and the abutting plate 16 is butted against the insertion groove 15. The tubular holder 12 is fixed to the mounting plate 10 by fitting the clip 33 formed of a spring plate, and then the terminal tube 5 is attached to the compression coil spring 32.
The front end of the inner cable 3 is connected to an actuating member (not shown) by pushing forward against the resilience of the inner cable 3 and finally, the locking member 28 is picked up by the knob 29 and the fitting claw 30 thereof is inserted. When it is pushed forward while escaping from the positioning hole 22 on the rear side, the upper and lower inner edges of the front surface of the locking member 28 are fixed to both claw pieces.
When the outer surface of 24 is pressed to bend the claw piece 24 inward from the easy-bending portion 25, the fitting claw 30 is fitted into the positioning hole 21 on the front side, and the locking member 28 is fixed at the forward position, as shown in FIG. Thus, the locking teeth 26 of the claw piece 24 mesh with the unevenness of the locking surface 7 of the terminal tube 5, so that the terminal tube 5 is attached so as to be immovable in the axial direction.

の張力が付与される。In this embodiment, a compression coil spring 32 is mounted between the tubular holder 12 and the terminal tube 5, and the elastic force of the compression coil spring 32 causes the terminal tube 5 to exert a biasing force in the direction indicated by the solid line arrow in FIG. Is added,
A constant tension in the same direction is applied to the outer casing 2 and the inner cable 3.

を行なうことができる。Further, the concavo-convex of the locking surface 7 of the terminal tube 5 is formed in a sawtooth shape such that the front side is a right-angled surface and the rear side is a slanted surface. Since the structure is formed in a sawtooth shape, when the locking teeth 26 engage with the locking surface 7, the inner cable 3 is pulled in the direction of the broken line arrow in FIG. Since the right-angled surface of the locking surface 7 of FIG. 5 is locked by the right-angled surface of the locking tooth 26, the meshing load for locking the terminal tube 5 is high, and the locking by the bending of the claw piece 24. When the teeth 26 are engaged with the unevenness of the locking surface 7 and the pitch is displaced, the slant surface of the locking tooth 26 presses the uneven surface of the locking surface 7 and always slides the terminal tube 5 forward. Therefore, the terminal tube 5 can be locked without increasing the tension applied to the inner cable 3.

また、端末筒５の凹凸を付けた係止面７は必ずしも上下
両面に形成する必要はなく、一面に形成するだけでもよ
い。Moreover, the engaging surfaces 7 having the projections and depressions of the terminal tube 5 do not necessarily have to be formed on both upper and lower surfaces, and may be formed on only one surface.
