Reference numeral 6 denotes a groove-shaped strip, which has an opening 7 formed on one side and has a cross-sectional groove shape, and is erected on the hoistway 1 so that the hanging portion of the fixed portion of the moving cable 3 is housed in the groove 8. The periphery of the pulley 5 is fitted to the pulley 7 while forming a gap. Numerals 9 denote projecting portions, which are formed on both edges of the opening 7 of the channel-shaped strip 6, respectively, and are provided so as to project outward.

Reference numeral 10 denotes a brush body, which is an opening 7 of the groove-shaped strip 6.
It is arranged along the length at the edge, is provided in a flocking state in a direction facing the side surface of the tension wheel 5, and is arranged so as to close the opening 7. Reference numeral 11 denotes a guide device, and a tensioning wheel 5 is pivotally mounted at an intermediate portion, and a support plate 12 provided above and below the intermediate portion, and a projection 9 of the groove-shaped strip 6 provided on the support plate 12 in a horizontal plane. The roller guide shoe, which is a roller guide shoe composed of rollers disposed to face each other in three directions, that is, a guide 13.

In the moving cable apparatus for an elevator configured as described above, a control signal and the like are transmitted from the hoistway 1 to the car 2 by the moving cable 3. In addition, the hanging curve 4 of the moving cable 3 moves in the vertical direction as the car 2 moves up and down. A brush body 10 is provided so as to close the opening 7 of the channel 6, and the fixed portion suspension side of the moving cable 3 housed in the groove 8 of the channel 6 moves from the inside of the groove 8.
