- 摘要：
PROBLEM TO BE SOLVED: To prevent separation of the respective layers of a skin layer molded in a multi-layer and to improve moldability.
SOLUTION: A flexible tube 10 includes: a cylindrical flexible tube raw material 14 and a two-layer skin layer 15 molded by stacking an inner layer 17 covering the whole peripheral surface in the circumferential direction of the flexible tube raw material 14 and an outer layer 18 covering the whole peripheral surface in the circumferential direction of the inner layer 17. When seen in a cross-section orthogonal to the axial direction of the flexible tube raw material 14, an interface 19 where the outer peripheral surface of the inner layer 17 and the inner peripheral surface of the outer layer 18 touch each other is shaped like an imperfect circle, to be concrete, an ellipse having the major axis R
L and the minor axis RS .COPYRIGHT: (C)2011,JPO&INPIT
