A pin hole 18 is bored at the tip of the pin hole 18 . Also,
Narrow parallel walls 16c and 16d are formed at the other end of the unit member 10, and the narrow parallel walls 16c and 16d are provided with wide parallel walls 16c and 16d of the unit member 10 adjacent to and pivotally connected to the unit member 10. A pair of engagement pins 20 that are loosely inserted into and locked in each of the pin holes 18 of the walls 16a and 16b are bored in accordance with the positions of the pin holes 18.

Accordingly, the guide chain of the present invention is made up of a plurality of unit members 10 having the above-mentioned structure connected in a line as shown in FIG. , narrow parallel walls 16c and 16d of adjacent unit members 10
are inserted into the respective pin holes 18 of the wide parallel walls 16a and 16b of the unit member 10, and the narrow parallel walls 16c and 16 of the adjacent unit member 10 are inserted into the pin holes 18 of the wide parallel walls 16a and 16b of the unit member 10.
The engagement pin 20 of d is loosely inserted and locked, and the ends of the adjacent unit members 10 are pivotally connected to each other so as to be rotatable within a predetermined plane. Further, by pushing the wide parallel walls 16a and 16b outward, the joints can be separated.

The ring portion 14 of each unit member 10 constituting the guide chain is composed of two flexible thin plate-shaped parallel extending frames 14a and 14b,
A cutting portion 22 formed of an extremely thin plate-like member that can be separated approximately in the center of the extended frames 14a and 14b.
is provided. The cut portion 22 facilitates molding of the ring portion 14 using a synthetic resin material, and also prevents deformation of the ring portion 14 during assembly of the guide chain.

Therefore, when using the guide chain, one end of a guide chain of an appropriate length is fixed to a movable part of a mechanical device, the other end is fixed to a predetermined fixed part of a mechanical device, and the guide chain is A guide chain connects the movable part and the fixed part of the mechanical device by appropriately bending the parts within a predetermined plane, and
Using a knife or the like, cut the cutting portion 22 that connects the approximately central portions of the extended frames 14a and 14b of each ring portion 14 of the connected guide chain, bend the extended frames 14a and 14b, and press A cable, hose, etc. is inserted into the through hole 12 of each unit member 10 that is penetrated between the extended extension frames 14a and 14b along the guide chain, and the flexible part of the mechanical device is opened.
