In the case of compressing the wire rope 7 together with the socket portion 14 and integrally molding the same, in order to obtain sufficient strength, if the diameter of the wire rope 7 is d, the length of the compressed portion of the wire rope 7 is 6d. There is a need. For this reason, there is a problem that the socket section 14 must be longer than the case of the babbit filling. Furthermore, when performing integral molding,
In order to prevent the socket 14 from cracking,
As the material No. 4, it is necessary to use a material having a lower carbon content and a relatively lower hardness than S45C or the like among carbon steel SC materials. Therefore, there is a problem that the dimensions of the socket portion 14 must be enlarged in order to give the socket portion 14 the same strength as the conventional one.

うにしたものである。According to the present invention, the rope is not compression-fixed directly at the socket portion, but the rope is compression-fixed by a sleeve into which the outer shape of the compression-fixed rope is tapered. By connecting the tapered portion to the socket portion, sufficient strength can be provided even if the length of the compressed portion of the rope is about 4d, and a material having high hardness can be used for the socket portion. Things. . Furthermore, the present invention is configured such that the socket portion is fitted into the tapered portion of the sleeve and the recess is formed so that the rope can be stuffed with a babbitt.
In addition to the above-described effects, compatibility with Babbitt stuffing is provided.

This will be described below. FIG. 1 is a front view, and FIG. 2 is a view showing a sleeve. In the figure, reference numeral 20 denotes an insertion portion 21 into which the wire rope 7 is inserted.
2 is a sleeve comprising Reference numeral 30 denotes a socket portion provided with a tapered hole 31 fitted into the tapered portion 22 of the sleeve 20, and the same reference numerals as those in FIG.

ワイヤロープ７の切り縮めも現場で行うことができる。As described above, in the present embodiment, the socket portion 30 is not plastically deformed.
A material having high hardness can be used. Further, in an elevator, the wire rope 7 may be elongated due to long-term use, and the wire rope 7 may be cut or shrunk. In this case, the conventional technique shown in FIG. In the present embodiment, since the sleeve 20 can be changed to a babbit-filled portion,
The wire rope 7 can also be cut and contracted on site.

It is not always necessary to fit them, and it is sufficient that the sleeve portion 20 can support the sleeve 20. Further, if the hemp core of the portion to be compressed of the wire rope 7 is removed and a steel core having the same hardness as the wire rope 7 is inserted instead, the volume of the wire rope 7 does not decrease at the time of compression. , The holding force of the wire rope 7 can be increased. Further, the present invention can be similarly implemented by using an equivalent material for the sleeve even if the rope is made of a material other than a steel wire such as a synthetic resin.

Because the sleeve with the tapered portion is used, the length of the compressed portion of the wire rope can be relatively shortened,
It is possible to realize a rope terminal device in which the socket portion can be made small and further, the installation can be changed to babbing after installation.
