屈曲不能にして相互に連結されている。Embodiment FIGS. 1 to 3 show an embodiment of the present invention. FIG. 1 is a front view showing the bent state of the inner surface of the link plate of the cable drag chain, and FIG. 2 is a top perspective view of the upper connecting rod 3. The cable drag chain 1 that stores, inserts, and guides cables, etc., is
The ends of a large number of link bodies 2 are overlapped and connected to each other and sequentially connected by connecting pins, and each link body 2 is connected in one direction between the fixed end F and the movable end M of the cable drag chain 1, for example, As shown in the figure, they are bendable in the downward direction, but are connected to each other in a manner that they cannot be bent in other directions, for example, upward.

が侵入しないように密閉されている。 One end of the upper side connecting rod 3 is rotatably fitted around the upper side of one link plate 4a, and the other end center portion of the upper side connecting rod 3 is fitted inwardly to the upper side of the other link plate 4b. It has a fitting coupling part 8 which is fitted into a snap locking part 7 protruding toward. The overlapping cover parts 3a and 3b formed on both side edges of the upper side joining rod 3 respectively cover one side 3b of the overlapping cover parts of the adjacent one upper side joining rod 3 so that there is no gap, and The cable drag chain 1 is covered with the other overlapping cover part 3a of the cable drag chain 1 without any gaps, and is sealed to prevent foreign matter from entering the cable drag chain 1 from the outside.

る。 Therefore, when an external pressing force is applied from above to the overlapping cover portion 3b of the upper side connecting rod 3, the fitting joint portion 8 of the upper side connecting rod 3 is pressed against the link plate 4b.
Since only the center portion is fitted by the snap locking portion 7, a tilting moment is generated in the upper side connecting rod 3 due to the external pressing force, causing the overlapping cover portion 3b to tilt downward. A gap is formed between the overlapping cover part 3a and the overlapping cover part 3a, which poses a risk of foreign matter entering, and the fitting part 8 may come off from the snap locking part 7.

Polymerization cover part 3a if necessary
A locking claw 9' is also formed protrudingly on the side, and the locking claw 9,
9' are respectively engaged with locking recesses 10 and 10' formed on the inner surface of the link plate 4b.

ことができるものである。Effects of the Invention As described above, the present invention provides a locking pawl 9 protruding from the end surface 3c of the end portion of the upper side connecting rod 3 having the fitting connection part 8 at at least one location separated from the fitting connection part 8. As a result, even if an external pressing force is applied to the upper side connecting rod 3, the upper side connecting rod 3 will not tilt around the fitting joint part 8, so that the overlapping cover parts 3a and 3b of the adjacent upper side connecting rods will not be tilted. There is no risk of a gap occurring,
Therefore, it is possible to prevent foreign matter from entering into the cable drag chain from the outside, and there is no risk that the fitting connection between the upper side connecting rod and the upper side of the link plate will separate, so that airtightness can be maintained. Moreover, since tilting is prevented, torsional stress is not generated in the upper connecting rod, so a durable cable drag chain can be obtained.
