ROTARY HOLDER FOR CORRUGATED TUBE

摘要

PROBLEM TO BE SOLVED: To provide a rotary holder which smoothly rotates an inner rotary body even if positional dislocation is caused in respective butting surfaces between a plurality of fixed dividing members.

SOLUTION: In this rotary holder 20 for a corrugated tube, the inner rotary body 22 is housed in an outer fixed body 21 for holding the corrugated tube 23, and an outer peripheral sliding surface 35 of this inner rotary body 22 slides on an inner sliding surface 26 of the outer fixed body 21. The outer fixed body 21 has circular arc surfaces 28b and 30b on the inner periphery, and is composed of a base member 24 and a cover 25 by abutting the respective abutting surfaces 28a and 30a. The inner sliding surface 26 is formed of the respective circular arc surfaces 28b and 30b of the base member 24 and the cover 25. An outside leaving surface 32 positioned outside a virtual circumferential locus of the circular arc surface 28b is extended to an end part of the circular arc surface 28b of the base member 24. Mutual both end parts of the circular arc surface 30b of the cover 25 is set to a dimension coincident with a tip surface of the outside leaving surface 32.
