- the rotary connector 1 of this embodiment includes a dummy tape assembly 60.
- the dummy tape assembly 60 of the present embodiment is manufactured by a method including a tape body creation process and a folding process.
- the tape body creation step one tape body 70 is created.
- the tape body 70 integrally includes a plurality of dummy tape portions 61 having different lengths in the longitudinal direction and a folded portion 62 that connects the end portions of the dummy tape portions 61 in the longitudinal direction.
- attachment holes 63 for attachment to the rotary connector 1 are formed.
- the tape body 70 is folded by the folding unit 62.
- FIG. 13 is a side view showing the overall configuration of the dummy tape assembly 60x of the second embodiment.
- the same or similar members as those of the above-described embodiment may be denoted by the same reference numerals in the drawings, and description thereof may be omitted.
- the tape body 70 includes, in order from one end in the longitudinal direction, a first dummy tape portion 61a, a folded portion 62a, a second dummy tape portion 61b, and a folded portion. 62b and a third dummy tape portion 61c are arranged.
- the three dummy tape portions 61 have a length that increases in the order of the first dummy tape portion 61a, the second dummy tape portion 61b, and the third dummy tape portion 61c. It is configured.
- the folding direction in the folded portion 62a and the folded direction in the folded portion 62b are reversed, and the tape body 70 is folded in a zigzag shape as shown in FIG.
- the dummy tape assembly 60x of the present embodiment can improve the quality by reducing the positional deviation between the dummy tape portions 61, and can simplify the work process. .
- the three dummy tape portions 61a, 61b, and 61c can be changed to various lengths.
- the number of dummy tape portions 61 is three, but the number is not necessarily limited to three.
- the effect of the above embodiment can be realized if the number of dummy tape portions 61 is two or more.
- the number of dummy tape portions 61 may be two or four or more.
- the process of making the folded portion 62 convex in the thickness direction may be applied to the configurations of FIGS. Moreover, as shown in FIG. 11 etc., you may apply the structure which makes the width
- a process of forming a V-shaped groove may be performed instead of the process of making the folded portion 62 convex in the thickness direction. Also in this case, it is possible to facilitate the folding at the folding portion 62.
- the position and shape of the mounting hole 63 are not limited to the above embodiment, and can be changed as appropriate according to circumstances.
