<p><P>PROBLEM TO BE SOLVED: To provide a cable burying ceramic protecting tube in which a trouble such as a crack hardly occurs even if the contact of protecting tubes occurs or the impact of a falling object or the like is given thereto. <P>SOLUTION: Band-shaped protrusions 5 are formed on the external peripheral surface of a nearly square columnar body 1 having six cable insertion holes 2 circular in cross sections. The band-shaped protrusions 5 are uprightly formed so as to be nearly orthogonal relative to the external peripheral surface of the body 1, slightly bent halfway to form nearly L-shapes in the cross sections, and extended in the longitudinal direction of the body 1 at equal intervals. The width between rising parts of the band-shaped protrusions 5 is nearly 5.0 mm, the height of the rising part is nearly 9 mm, and the interval is nearly 10 mm. <P>COPYRIGHT: (C)2004,JPO</p> |
