<p><P>PROBLEM TO BE SOLVED: To provide a cable trough that enables a connection portion to be formed between both ends of the cable trough according to remaining laying length, when the laying length of the expected laying area is shortened. <P>SOLUTION: The trough 1 of roughly a U shape in cross section, which is made of a synthetic resin and laid being connected to each other, has a female connection portion 2 on the ends of both inside surfaces of which locking pieces 20 are formed at one end side in the longitudinal direction of the trough, a male connection portion 3 on the ends of both outside surfaces of which locking projections 30 corresponding to the locking pieces 20 are formed at the other end side in the longitudinal direction of the trough and which is guided into the female connection portion 2 in a dropped-into state, foot stripe portions 4 at both sides of a bottom surface except at least the male connection portion 3 along the longitudinal direction, vertical ribs 5 at the same positions in the longitudinal direction of both outside surfaces at prescribed intervals, and dimensions which enables both sides of the cut surfaces except the foot strip portions 4 at the cut portion to be engaged with the locking pieces 20 of the female connection portion 2, when the trough is cut in a state perpendicular to the longitudinal direction at a position including either one of the vertical ribs 5. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
