<p><P>PROBLEM TO BE SOLVED: To provide a movement prevention device for an in-conduit cable, which can be installed in a conduit without the need of securing an installation space in a manhole, even if a space between a cable and the inner wall of the conduit is narrow. <P>SOLUTION: A movement prevention device for an in-conduit cable includes: a cable presser fitting 3 striding over a cable 2 laid in a conduit 1; a lower side wedge piece 4 which is provided on the cable presser fitting 3 so as to be vertically movable along with the fitting but immovable in the conduit direction with respect to the fitting and of which top face is an inclined plane; an upper side wedge piece 5 which is provided between the lower side wedge piece 4 and a ceiling plane in the conduit so as to be movable in the conduit direction and of which bottom face is an inclined plane sliding with the inclined plane of the lower side wedge piece 4; and a shaft 6 which moves the upper side wedge piece 5 in the conduit direction. The lower side wedge piece 4 and the cable presser fitting 3 are pushed downward by drawing the upper side wedge piece 5 to a conduit opening by the shaft 6, thereby pushing and restraining the cable 3 to the inner face of the conduit. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
