ABSTRACT:
A flexible tube includes a number of joint members each having a neck portion of reduced diameter formed between a spherical member and a semi-spherical member. The joint members have a hollow passage for engaging with electric wires. The spherical members each has an annular tapered surface, and the semi-spherical members each has an annular tapered surface formed in the inner peripheral portion for engaging with the annular tapered surface of the spherical member so as to limit a rotational movement of the spherical member relative to the semi-spherical member.
