Abstract

An operating wire has a multi-twisted structure constituted by twisting side strands, each formed by twisting element wires together around a core strand. A side element wire of the side strand faces the outside of the operating wire in the radial direction at a site located on the outer circumference of the operating wire and has a flattened surface where a flat portion provided in a portion of the side element wire in the circumferential direction extends in the X axis direction, the length in the X axis direction of the flattened surface being 4.8-11.0 times the diameter of the side element wire, and the pitch magnification of the side strand being 7.0-12.0 times the diameter.

First claim

The invention claimed is:

1. An operating wire rope having a multiple strand structure, wherein:
the multiple strand structure is composed of
a core strand composed of a plurality of element wires which are twisted together, and
a plurality of side strands disposed around the core strand, each of the side strands being composed of a plurality of element wires which are twisted together, the core strand and the side strands being twisted together;

a side element wire of the side strand includes a smooth surface at a portion located on an outer periphery of the operating wire rope, the smooth surface comprising a flat part which is provided facing radially outside of the operating wire rope at a part of the side element wire in a circumferential direction, the flat part extending along an axial direction;
an axial length of the smooth surface is 4.8 to 11.0 times a diameter of the side element wire; and
a pitch multiplying factor of the side strand is 7.0 to 12.0 times, the pitch multiplying factor being defined as a value obtained by dividing a strand pitch length of the side strand by an outer diameter of the operating wire rope.

2. The operating wire rope according to claim 1 , wherein the axial length of the smooth surface is 5.8 to 9.2 times the diameter of the side element wire.

3. A wire operation mechanism comprising:
a driving part;
a driven part; and
a direction turning member made of a resin, wherein:
the driving part and the driven part are connected together through the operating wire rope according to claim 1 ,
the operating wire rope is set around the direction turning member with a predetermined load, and
when the operating wire rope is moved by driving the driving part to move the driven part, the operating wire rope moves in a direction in which the operating wire rope extends with respect to a position of the direction turning member.
