<p>PURPOSE:To prevent a wire harness from protruding from a slit at the time of bending by forming any one of small or large diameter part of bellows into an ellipse and the other into a circle and by forming a slit for inserting the wire harness in the maximum diameter-difference part of an elliptical part and circular part. CONSTITUTION:In a colgate tube 1, the small diameter part 3 of bellows 2 is formed into a circle and the large diameter part 4, into an ellipse and a slit 6 for inserting a wire harness is formed in the longer direction relative to the maximum diameter-difference part 5 of a circular diameter part 3 and an elliptical part 4. At the time of bending the colgate tube 1, the major axis D side of the elliptial part 4 has a sufficient deflection quantity so that the slit 6 is prevented from opening circumferentially. Thus, it is possible to prevent a wire harness from protruding from the slit 6 at the time of bending.</p> |
